    • Abstract
  • By changing the contents of MoS2 (mass fraction 1.0%~2.0%) and graphite (mass fraction 0~1.0%), the bearing pressure limit value of bronze oil bearing at the certain sliding linear velocity was measured, the effects of MoS2 and graphite contents on the mechanical and frictional properties of bronze oil bearing were studied. The results show that, the limit value of load×linear velocity (pv) for the oil bearings decreases with the increase of MoS2 content without graphite addition, and the bronze-1MoS2 (1.0%MoS2, mass fraction) oil bearing has the highest pv value of 2.940 MPa·m·s-1. In the case of adding graphite and MoS2 at the same time, the friction coefficient of the oil bearing decreases with the increase of the graphite content, and the bronze-1MoS2-1graphite (1.0%MoS2 and 1.0%graphite, mass fraction) oil bearing has the lowest friction coefficient of 0.038. Graphite can improve the friction properties of oil bearings, but it may greatly reduce the mechanical properties of oil bearings.
