Abstract
The grease for roll bearing is a high-performance roller bearing grease that uses composite metal soap to thicken and deeply refine mineral base oil and adds various functional additives.It has good high-temperature resistance,adhesion,and ex-treme pressure and wear resistance.Faced with complex working conditions such as high temperature,water,heavy load,and long cycle,the use of roller bearing grease in the centralized lubrication system of a large steel plant production line is not suitable,re-sulting in occasional poor adhesion and easy loss.This study aims to increase the maximum refining temperature of the reaction process,adjust the ratio of high viscosity HVI 120 BS and HVI 750 base oil for production,and adjust the types of additives.By adding 2%antioxidant A2 and 1.5%extreme pressure and wear resistance B2,the soap content of the grease for roll bearing can be reduced,the adhesion of the grease for roll bearing can be improved,and the extreme pressure and wear resistance and oxidation stability can be improved.In practical applications,the problem of poor adhesion and easy loss can be effectively improved.关键词
