Gear Tooth Contact Analysis of Cycloidal Pinwheel Transmission Mechanism of RV Reducers
Abstract
The loaded tooth contact analysis of cycloid pin wheel transmission mechanism of RV reducers is the basis of lubrication analysis of the mechanism. To clarify the dynamic contact characteristics between the cycloidal gear teeth and the needle teeth, as well as between the roller needles and the inner and outer rings of the crankshaft bearing, based on the meshing principle of the cycloidal needle gear transmission mechanism, the kinematic characteristics of the gear tooth clearance and meshing points under six different tooth profile modification methods are analyzed; combining the static equilibrium equation and deformation coordination conditions, the nonlinear Hertz contact stiffness is introduced and a three-dimensional dynamic load-bearing contact analysis model of the cycloidal needle gear transmission mechanism is established. The load deformation of the gear teeth with initial clearance is determined, and the model solution is completed using the iterative method. The time-varying force characteristics at the meshing of the gear teeth and the inner and outer rings of the crankshaft bearing roller needles during the transmission process are clarified.
