Abstract

The invention discloses a high-temperature high-speed pin disc friction testing machine. The testing machine is provided with a main transmission system, a loading system, a friction disc clamping device, a heating device, a numerical control feeding device and a data acquisition system; a friction disc sample is mounted on the friction disc clamping device; a friction pin sample is connected withthe numerical control feeding device through a cross beam and a lead screw; the friction disc sample and the friction pin sample are arranged opposite to each other to form a friction pair; a heatingand cooling device is arranged by the side of the friction disc sample and the friction pin sample; an input end of the data acquisition system is connected with a testing system; an output end of the data acquisition system is connected with a computer. By adopting the high-temperature high-speed pin disc friction testing machine, high-speed steady rotating of a rotating main shaft of the testing machine and quick heating of the surface of a friction pair sample can be realized.

Description

technical field [0001] The invention discloses a high-temperature and high-speed pin-on-disc friction testing machine, which is especially suitable for evaluating the friction and wear performance of materials at high speed and high temperature, especially for studying the service conditions of new cutting tool materials for high-speed cutting, and evaluating the cutting tool itself and coating materials Tribological properties at high speed and high temperature. Background technique [0002] According to incomplete statistics, about 1 / 2~1 / 3 of the world's energy is consumed in friction in various forms, and about 80% of damaged parts are caused by various forms of wear. Abrasive wear is the most common type of sheet wear in industrial applications, accounting for approximately 50%. According to incomplete statistics, my country consumes more than one million tons of steel every year due to abrasive wear. Some common high-temperature working environments, such as the grate...
