Evaluation of rear axle extreme pressure (ep) lubricants by a disc machine

Abstract The performance evaluation of extreme pressure lubricants for hypoid rear axles is a time-consuming and expensive process. A method for performance evaluation which utilizes a disc machine is described. Initial work shows that by using a special technique CRC reference gear oils can be clearly classified under shock loading conditions. The importance of a critical rise in friction and film conditioning with regard to scuffing was briefly considered.
