"Bearing Failures"...
Mike Page, Editor, writes:
We see from your search that you're looking for information on the term "Bearing Failures", and we have a large number of manufacturers' news releases and technical articles here on Manufacturingtalk which will be of interest. Let me be your guide. Start with the news release Vibration monitor detects rolling element failures from IFM Electronic, which we summarised at the time by saying "A cost effective predictive maintenance vibration monitor detects rolling element bearing failures and shaft imbalance conditions even where there is an explosion hazard". A couple of weeks before, we featured the news release Failure prediction with vibration monitor from IFM Electronic: "Preventive maintenance becomes more effective with bearing condition monitoring using vibration sensors". In June 2007, we covered the news from Revolvo concerning its Bearings - take a look at Longer bearing life needs whole life consideration which says: "Adrian Menzies of Revolvo discusses how reducing downtime due to bearing failure requires an approach where whole life costs are paramount". Take a look also at the news release from Morgan Construction Company, New gearbox speeds mill, as well as Heavy duty baseplate design chemical pump from CDR Pumps (UK), and Condition monitoring improves engine manufacturing from SKF UK.

next generation internet
Coming Soon: Next Generation, Super-Fast Grid Internet
A super-fast, new global network's controllers will turn it on sometime this year, but exactly when it will be available to you and me, in the same way the Internet we know is today... Only time will tell.As is practically always the case, the new technology driving the "Grid" network was borne out of need.
The Times Online published an article discussing the new network:
"Cern, based near Geneva, started the grid computing project seven years ago when researchers realised the LHC would generate annual data equivalent to 56m CDs - enough to make a stack 40 miles high."This meant that scientists at Cern - where Sir Tim Berners-Lee invented the web in 1989 - would no longer be able to use his creation for fear of causing a global collapse."This is because the internet has evolved by linking together a hotchpotch of cables and routing equipment, much of which was originally designed for telephone calls and therefore lacks the capacity for high-speed data transmission."By contrast, the grid has been built with dedicated fibre optic cables and modern routing centres, meaning there are no outdated components to slow the deluge of data. The 55,000 servers already installed are expected to rise to 200,000 within the next two years."Imagine high-definition holographic video conferencing, or downloading movies and other massive pieces of data (well, massive by today's standards anyhow) in a couple seconds or less.
Even if the Grid network is never made available to the public and is used solely by researchers, the technologies that are created and used to drive it can be used in the public space to drive change for everyone.
Let's just hope people seriously think about security this time around, during design rather than after the fact.(one of several interesting links found today via Warner Crocker)

BOMBAY MOTOR STORE
BOMBAY MOTOR STORE was established in 1968 under the able leadership of Mr. R.G. Shah, as an importer of automobile spare parts. At that time India with almost no manufacturing base in the automotive segments, was mainly serviced by European and American companies, leading to expensive replacement parts to the Indian vehicle owner.
In order to provide quality products at competitive prices, in the seventies, BMS started indigenously manufacturing replacement parts applicable to vehicles which were then running on the Indian roads. Manufacturing activity actually started with precision parts like Carburetor Jets, Needles, floats etc for European & American vehicles like Austin Morris, Mercedes Benz, Opel, Dodge Etc. and gradually expanded to other Parts applicable to Engine, Gear Box, Steering & Suspension. Since then BMS has gained critical acclaim for its workmanship in the Indian replacement market for all types of vehicles including four wheelers, cross country vehicles, light-medium-heavy commercial vehicles plus tractors & farm equipment, thereby becoming a one-stop-shop for genuine replacement parts.
Mr.R.G.Shah was soon joined by his two sons - Mr. Amrish Shah and Mr. Anup Shah - who with their techno-commercial background gave a new direction to the company. To match with the market demand, they brought a new concept of kit packaging (as generally prescribed by the workshops), thereby making it convenient for the consumers to have all the parts in a single pack. They introduced a new trademark - AUTO77 - which till date specializes in replacement parts for four wheelers and LCVs, in applications like Overhaul kits for Gear Box, Suspension, Steering mechanism and Conversion kits for gear change (Column shift to floor shift) & OF COURSE Individual spare parts.
During the 1980s the Indian automobile industry saw the invasion of Japanese technology in this segment. Needless to mention this brought prominent players like Toyota, Mitsubishi, Hyundai, Suzuki and Maruti. This came along with a demand for a new kind of technically advanced Automobile Spare parts. BMS successfully capitalised on this opportunity by venturing into developing replacement parts for the Japanese vehicles. This was a result of continuous Research and Development and resulted in giving a new business dimension to BMS.
Impressed by the quality products, many leading Indian Exporters of Automobile Spare Parts tied up with BMS to provide them with parts on the basis of prototypes of international brands. This has proved BMS' credentials on the international scenario.
Due to its world class product, expertise in various automotive segment, quality and pricing, BMS has now eyed for global opportunities, INDEPENDENTLY.
BMS has carved out a niche for manufacturing Spare Parts based on prototypes and the range includes not only domestic automobiles but major American, Japanese, and European automobiles.

Executive summary
General tolerances for linear and angular dimensions without individual tolerance indications.
Abstract
This part of EN 22768 is intended to simplify drawing indications and it specifies general tolerances for linear and angular dimensions without individual tolerance indications in four tolerance classes.
This European Standard applies to the dimensions of parts that are produced by metal removal or parts that are formed from sheet metal.
This standard only applies to the following dimensions which do not have an individual tolerance indication:
a) linear dimensions (e.g. external sizes, internal sizes, step sizes, diameters, radii, distances, external radii and chamfer heights for broken edges);
b) angular dimensions, including angular dimensions usually not indicated, e.g. right angles (90 degrees), unless reference to ISO 2768-2 is made, or angles of uniform polygons;
c) linear and angular dimensions produced by machining assembled parts.
This standard does not apply to the following dimensions:
- linear and angular dimensions which are covered by reference to other standards on general tolerances;
- auxiliary dimensions indicated in brackets;
- theoretically exact dimensions indicated in rectangular frames.

A pressing instrument for pressing bushings, cable lugs, or similar items
Pressing instrument for pressing on bushings, cable lug presses, or similar items
Document Type and Number:
United States Patent 5644944
Link to this page:
Abstract:
A pressing instrument for pressing bushings, cable lugs, or similar items upon a work piece reveals two tools that can be brought together with the help of a drive mechanism, forming a pressing chamber, with each tool revealing two opposite pressing cheeks, whose pressing surfaces are shaped so that a polygonal shape will result during pressing. In order that work pieces of differing diameter can be processed with the pressing tool, that production costs can be kept comparatively low, and that good operational reliability can be achieved, opposite pressing cheeks (10, 11; 36, 37, 54, 55) of at least one tool (4, 34, 35) can be swung on them so that the other tool (5, 34, 35), as the tools are brought together (4, 5, 34, 35), will run against the swingable pressing cheeks (10, 11, 36, 37, 54, 55) and will swing them out of a starting position into a pressing position forming the pressing chamber.

corrosion inhibiting grease
Title: Study on tribological and corrosion inhibiting properties of thiadiazole derivative as lubricant grease additive
Author(s): Jian-Qiang Hu, Xian-Yong Wei, Zhi-Min Zong
Journal: Industrial Lubrication and Tribology
ISSN: 0036-8792
Year: 2006 Volume: 58 Issue: 6 Page: 320 - 323
DOI: 10.1108/00368790610691400
Publisher: Emerald Group Publishing Limited
Abstract: Purpose – Pure 2,5-dimercapto-1,3,4-thiadiazole (DMTD) disulfide dimer (DMS2) shows excellent four ball weld properties, however, the product is a solid material with relatively low initial seizure load and exhibits certain corrosion, which accelerate oxidation of the lubricant by catalytic effect on metals. The author make efforts to resolve problems said by design a novel thiadiazole complex. Design/methodology/approach – The complex of thiadiazole dimmer and polyglycol (DMS2-GL) was synthesized as ashless grease additive. The antiwear and load carrying properties of the additive and their synergistic effects was evaluated by four ball tester in four types of lubricant grease. Moreover, corrosion inhibiting properties of compositions said was investigated by copper corrosion test. Findings – The additive DMS2-GL possessed good load carrying capacity, and exhibits good synergistic antiwear and load carrying prop with rust inhibitor. In addition, dates obtained from copper corrosion test show that it does not corrode copper but coats the metal with a film, and could improve the anticorrosion of corrosive additives molybdenum dialkyldithiophosphate (MoDDP) and molybdenum dibutyldithiocarbamate (MoDTC) by forming protective films on rubbing surface, which contribute to improving corrosion inhibiting property of greases. Finally, the tribo-chemical mechanism was proposed that thiadiazole dimer and polyglycol could coordinate with each other by polydentate surface interaction, which means thiadiazole rings interact with the metal surface, polyglycol affords a bridging technology linked thiadiazole dimmers so as to lighten loads and strengthen forces between thiadiazole dimmer moleculars. Originality/value – This paper provides a good ashless additive which has good antiwear, extreme pressure and corrosion inhibiting properties, and fulfils an identified resources need, which can offer practical help in industrial applications and to an individual starting out on an academic career.

Non ferreous metals
CONCAST
HISTORY OF PROCESS AND EVOLUTION OF MACHINE DESIGN
Continuous casting of non-ferrous metals can be in the vertical or horizontal mode, the particular application generally dictated by the product size and volume of output. There are a number of definitions of continuous casting, possibly one of the more appropriate being 'the continuous solidification and withdrawal from a shaping mould. It may he inferred from this simple statement as a simple process. but the metallurgical complexities involved in the process have as their focal point the thermal and mechanical interactions between the mould and the moving solidifying shell of the casting. Neglecting for the moment the importance of economics in continuous casting, it is the heat transfer within the mould that is the overriding factor for the ultimate success of the process. Today casting plants are handling large-scale production of continuous cast and rolled strip in aluminium, copper,lead and zinc.
MODE OF CASTINGThe crucible is heated by induction or electric resistance to maintain the melt at the appropriate casting temperature. The crucible can act simply as a reservoir of liquid metal above the mould. being fed separately from a melting-furnace. Alternatively, the crucible can function as a melting. holding and casting chamber.The crucible can be manufactured in a suitable ceramic refractory with water- cooled graphite die assembly attached. High-quality graphite is used as the die or mould material in the majority of non-ferrous metals including all of the copper- based alloys, gold and silver alloys. The fully graphite-lined containment system for the molten metal used with submerged graphite dies and using inert gas protection is now applied to a wide range of applications.
Continous Casting Machine
Manufactures Casting MachineStoker manufactures casting machine is used to melt and cast in continuous lengths a wide range of copper and copper-based alloys. The applications of casting machinery are semi-finished rods, strips, tubes or other profiles. Our small table top machines are specially designed to process gold, silver and their alloys. This machine, therefore, converts scrap of almost all copper and copper-based alloys. It helps in cutting down costs drastically. The machine processes recycled expensive scrap, which results in reducing scrap wastage to the minimum.Design of Casting MachineStoker Concast has been technically designed according to the latest international standards and the manufacturers have taken care that it can be comfortably used in high temperature applications. It is also environment friendly as the furnace is completely sealed and kept under inert nitrogen gas atmosphere.Fumes coming out of it are negligible. Whether it is the cost of the machine, the technology behind it or its design, Stoker Concast triumphs on all counts. It is the first and the only jewelry making machine from India. It is making waves in and across the country's borders.Technical Data of Casting MachineStoker machines cover a wide range - from 10 Kg/hr to 250 Kg/hr for precious metals. The selection of machine depends on a particular application. The product sizes can range from as small as 6.0 mm diameter rods to billets of 150 mm diameter. The widest strip and section, upto150 mm width may be produced on large machines. Every model of the Stoker range of machines features great flexibility in terms of product profile and product alloy. A few minor modifications are required to change the machine from strip to rod production. AdvantagesA unique and distinctive feature of the Stoker Machines is that they are specially designed to suit difficult working conditions. A number of innovations have been introduced to meet the severe operating conditions under which users have to operate these machines.It has been designed to face the challenges like erratic electricity supply, non-availability of superior quality raw materials etc. All the models are electrically heated and operated on 3-phase input supply. Using three phases as input supply (a balanced load) it can be run on generator.At the time of commissioning the machine at the customer's site the transfer of technology is undertaken completely. Great emphasis is given to training of manpower in order to make the workers handle the machine independently.The casting machine is of significant use to those involved in the following:

During the recent survey of small to medium sized process plants in India especially those were built during 80’s and early 90’s it is my firm opinion that with a little bit fore-sightedness on the part of the plant owners a lot more problems faced by them on today would have been solved had they went with rudimental plant automation system at that time.
Now because of open market, post WTO regime, and severe competition Indian manufacturer finds it increasingly difficult time to deliver quality goods at international competitive prices. But this is not true with major plant complexes i.e. oil refinery, fertilizer complex or petrochemical complex etc where plant automation level remains one of the best in the contemporary world scenario. Obviously the most neglected sectors are small to medium size plants that suffer today due to initial shortage of funds and lack of proper advice or due to lack of vision. My areas of concerns and concentration is for these type of plants where a lot of advisory or counseling roles are required to introduce cost effective , appropriate and right automation system. For this only an experienced professional with good engineering consultancy background with wide exposure to various types of plant operating in India and abroad can offer right advice to plant owners.
Consequently most of such plants continue to suffer and some of the ills are as follows:
Poor control on quality or consistency of product.
Poor productivity.
Utility consumption per Ton / Kg of product is high.
Plant is highly labour intensive.
Management is victim of union people.
Because of prevailing culture management is reluctant to introduce automation.
Refusal to believe that plant automation can lead to overall improvement of the plant.
Cost to benefit ratio is not studied thoroughly and as a result reluctance to spend on incremental automation.

Engineering Drawing
Geometric dimensioning and tolerancing
Geometric dimensioning and tolerancing is a symbolic language used on engineering drawings and computer generated three-dimensional solid models for explicitly describing nominal geometry and its allowable variation. It is often referred to by the abbreviation, GD&T.
Geometric dimensioning and tolerancing is used to define the nominal geometry of parts and assemblies, to define the allowable variation in form and possibly size of individual features, and to define the allowable variation between features.
Dimensioning and tolerancing and geometric dimensioning and tolerancing specifications are used as follows:
Dimensioning specifications define the nominal, as-modeled or as-intended geometry.
Tolerancing specifications define the allowable variation for the form and possibly the size of individual features, and the allowable variation in orientation and location between features.
There are several standards available world-wide that describe the symbols and define the rules used in GD&T. One such standard is ASME Y14.5M-1994. This article is based on that standard, but other standards such as those from the International Organization for Standardization may vary slightly.
