The influence of granulometric composition of molybdenum disulfide on lubrication of rolling bearings

Abstract

In the work, laboratory tests are carried out to assess the wear of rolling bearings on the SMC-2 friction machine, depending on the granulometric composition (up to 1 and up to 7 microns) and the concentration of molybdenum disulfide added to the base industrial oil I-GT-A-100 (I-50A), produced according to GOST 20799- 2022. During the tests, numerical values of the wear condition of four bearings are obtained, the average value is indicated. The dependences of the concentration of molybdenum disulfide with a granulometric composition of up to 1 and up to 7 microns on the wear level and the average temperature of the bearing during the tests are determined.
