Research on Elastohydrodynamic Lubrication Theory of Rolling Bearing Type Planetary Friction Transmission Mechanism

摘要

Elastohydrodynamic lubrication theory is adopted in rolling bearing type planetary friction transmission mechanism in this paper. Operation performance and using life-span are improved. Minimal oil film thickness formula is deduced based on the elastohydrodynamic lubrication theory. Relationship curve between minimal oil film thickness and rotate speed is presented. Variation law between minimal oil film thickness and work parameters is given.
