Abstract

A vacuum tribometer was developed which was used to investigate the maximum friction force occurring at the initial instant of slipping in rubber-metal friction pairs under conditions of a given (from 5 to 40%) compressive strain at a low pressure in the temperature range from +100 to −100°C. Filled rubbers on a base of nitrile-butadiene rubbers were studied. Up to the glass transition temperature Tg the vacuum had practically no effect on the maximum friction frocefm; at temperatures Tg and lower the values offm obtained in a vacuum were 10–15% higher than those obtained in the atmosphere. It is shown that with a decrease of temperature from 20°C to the glass transition temperature Tg the slope of the dependence of the maximum friction force on the degree of deformation increases, and below Tg decreases. The effect of the slipping speed v on the maximum friction forcefm was also studied.
