Ultra Shear Viscometer

Ultra Shear Viscometer

Lubricant formulators have long been aware of the shortcomings of existing high shear viscometers. Whilst the state of the art in high shear rate viscometry has remained around the 1,000,000 reciprocal second mark for many years, developments in engine and lubricant technology mean that in-service conditions are more like 10,000,000 reciprocal seconds. Extending the measuring range of existing viscometers is […]

Wind Turbine Issues

The Statistics     Wind Turbine Components Gearbox Wind Turbine gearbox generally employs three stages of gear enhancements providing appropriate speed ratio between the low and high-speed shafts. Designed to handle highly varying loads from the low-speed driveshaft due to the transient nature of wind. Braking loads when the overspeed brake is engaged, as the […]

Micro and Macro Pitting

Definitions: Macropitting: A surface fatigue phenomenon that causes large pits to form on the surfaces in contact. These result from surface or subsurface initiated cracks propagating into large scale pits. Macropitting tends to occur in more heavily loaded contacts than micropitting. Micropitting: A surface fatigue phenomenon resulting in microscopic pits forming on the surfaces in […]

Biotribology is Everywhere

Biotribology is one of the most exciting areas of tribology research and one which affects every aspect of our every day life from skin blisters to artificial joints and contact lenses. In many cases interaction with our environment is governed by tribology and in particular our response to perceived friction. The use of touch to […]

MTM: Wet Clutch Screening

Research using the MTM has been carried out using an MTM Clutch disc, the specimen consists of a friction material coated steel disc, which is designed for the accurate screening of lubricants in a wet clutch type contact. The MTM Clutch Screening Method was used; this test configuration, which has been successfully used at Imperial College London, UK […]

Biotribology Investigation of Chocolate

Introduction A selection of chocolate samples produced by a popular Chocolate Brand were supplied to PCS Instruments for analysis using a bio-tribology technique. This shows the lubrication regime of the chocolate and how it is controlled by the constituents within the chocolate. Method The chocolate test samples where heated in an oven at 60°C for […]
