- Abstract
To reduce the wear of thrust washer within straight planetary gear set, hydrodynamic lubrication design was studied by way of machining grooves in the radial direction into sides of thrust washer. Such grooves can result in a hydrodynamic pressure to separate the contact surfaces and reduce the wear accordingly. Based on mass boundary conditions, the Reynolds equation was discretized using control volume method. The results show that, to increase the axial clearance and groove depth, to decrease groove width ratio and groove number can decrease the friction between planetary gear transverse and axial bearing surface. The fluid flow increased when groove depth and groove numbers increased. The bearings have the maximum load capacity when the groove number is 24 and the groove width ratio is 0.5. In engineering applications, make sure the groove depth is 10~40 m, and recommend assembling clearance between planet wheel and thrust washer is 5 m.
