Abstract

Previous work has suggested that the adhesion between oil and metallic surfaces of an engine could be an important factor in determining crankcase cleanliness. It can be shown that it is only necessary to measure the spreading pressure of an oil on metal in order to get a direct measure of the work of adhesion, Surface tensions of lubrictaing oils vary very little and it can be assumed that the critical film pressure (C.F.P.) obtained with a given apparatus is an acceptable measure of the work of adhesion as well as of the spreading pressure. Oils of similar properties may vary tenfold in their C.F.P's. The addition of additives influences the spreading pressure, the largest increments in C.F.P. being given by dispersant and detergent additives.

Abstract

The Eastern Region of British Railways are evaluating, on the tortuous 10 mile route between Liverpool Street and Chingford, methods of reducing flange wear on the wheels of multiple unit passenger trains. Among the greasing systems being studied is the Enots‐Vogel equipment designed for greasing both inner and outer faces of wheel flanges and supplied by Enots Ltd., Aston Brook Street, Birmingham 6. Equipment of this type has been in use on European railways for some time but only for the treatment of the outer faces of wheel flanges (this is because of a basic difference in railroad design practised there—in Europe check rails are, in general, only installed as parts of points, but in Britain they are often laid on curves so that check rail mileage often represents a significant proportion of total track mileage).

Abstract

Purpose

The CL60 steel wheels of subway vehicles operating on specific lines require frequent refurbishment due to rapid wear and tear. Considering this issue, MoS2-based and graphite-based solid lubricants are used to reduce the wear rate of subway wheels and extend their service life.

Design/methodology/approach

Under laboratory conditions, the effect of MoS2-based and graphite-based solid lubricants on the friction and wear performance of subway wheels and rails was evaluated using a modified GPM-60 wear testing machine.

Findings

Under laboratory conditions, MoS2-based solid lubricants have the best effect in reducing wheel/rail wear, compared to the control group without lubrication, at 2 × 105 revolutions, the total wheel-rail wear decreased by 95.07%. However, when three types of solid lubricants are used separately, the hardness evolution of the wheel-rail contact surface exhibits different characteristics.

Practical implications

The research results provide important support for improving the lifespan of wheel and rail, extending the service cycle of wheel and rail, reducing the operating costs of subway systems, improving the safety of subway systems and providing wear reduction maintenance for other high wear mechanical components.

Originality/value

The experiment was conducted through the design and modification of a GPM-60 testing machine for wear testing. The experiment simulated the wheel-rail contact situation under actual subway operation and evaluated the effects of three different solid lubricants, MoS2-based and graphite-based, on the wear performance and surface hardening evolution of subway wheel-rail.

Abstract

SELECTING the correct bearing for any particular application involves more than the determination of the correct type and size. It is true that the calculation of the nominal working life will give an indication of the operational life before failure, but this calculation only takes into account the fatigue life of the material. If this theoretical life is to be obtained—and perhaps exceeded—then additional factors must be taken into account when initially designing the bearing arrangement. Lubrication and protection from the operating environment are two very important considerations.

Abstract

Cooling samples of high‐temperature liquids. Sampling coolers (Fig. 1), designed for power stations, and those marine and industrial installations in which it is necessary to draw samples of liquids from vessels under conditions of high pressure and temperature, have been developed by Caird & Rayner Ltd., 777 Commercial Road, Limehouse, London, E.14. The coolers are also necessary in the operation of high‐pressure steam generating plant, where regular and accurate analysis of boiler water is essential.

Abstract

THE Engineering, Marine, Welding and Nuclear Energy Exhibition opens at Olympia on April 16th and runs until April 30. It is open from 10 a.m. to 6 p.m. each day (except Sundays), with the exception of April 27th, 28th, and 29th, when it remains open until 8 p.m. Price of admission is 3s. There are well over 500 stands and of these between 60 and 70 are showing products that should be of interest to most readers of Scientific Lubrication, since they concern some type of lubrication equipment. Amongst these are the following, and the illustrations reproduced here concern items which will be exhibited on the stands. Items in bold type describe new products or products being exhibited for the first time.

Abstract

PVC pipe wrapping Although many modern pipes come ready‐protected from the factories, removal of this protection for butt welding necessitates an alternative re‐protective method which is effective and quick to apply. John Gosheron & Co. Ltd., The Packaging and Industrial Tape Centre, 58–60 Kensington Church St., London W8, supply Polyvil PP.10 heavy duty pvc tape for this purpose. This form of anti‐corrosive wrapping is not only said to be comparatively cheap, but is also favoured by the operatives who apply it because of its clean handling and mess‐free application.

Abstract

Although increasingly used the power truck has never completely displaced the hand truck for even in fully mechanised establishments it can still justifiably find a place. The hand truck is a robust piece of equipment, made in various sizes and shapes. The simplest forms are the conventional two‐wheeled truck with either one or two handles, and the platform truck, which, with various arrangements of wheels and castors is used extensively for short hauls of light parts and cartons. Since the last war a large number of specially designed trucks have appeared for the carrying of particular materials or shapes of packages. Possibly the earliest member of the series was the barrel or cask truck but there are many others today, as, for example, those suitable for removing swarf.
