Abstract :
The influence of tribological behaviors of journal bearing Made of C83600 Red Brass alloy under dry sliding condition against a shaft made of stainless-steel shaft was investigated experimentally in the present paper. A special tribometer was developed and tests carried out under dry sliding conditions, actual radial load (RL) of (2000 and 3000) N and sliding velocity (250, 500, 1000, and 1500) rpm were applied. Changes in temperature, coefficient of friction COF, and weight loss of journal bearing were monitored. Increasing the radial load, sliding velocity, and sliding time resulted in increasing the average temperature. It was also detected that the friction coefficient decreases with the increasing of radial load RL and sliding velocity SV. On contrary, weight loss increases with increasing RL and SV.
