Entitative change of lubrication mechanism has taken place because kinds of additive are perfec-ted constantly, performance is advanced great extent, complex technology is constantly mature. Chemistry film replaces adsorb film. Mechanism of anti-extreme pressure is changed basically. Chemistry adsorb film replaces physics one. Adhere strength of lubricant on gear surface is increased in 5 times ~ 10 times. The problem which lubricant can not be put into engaged area does not exist Currently standards and criterions with aim ensuring oil film thickness and increasing viscosity, controlling temperature have not satisfied requirements. These standards and criterions must be revised on base of modern technology. This paper has demonstrated main problems in cur-rently standards and brings forward our opinions.
