DYNAMIC ANALYTICAL METHOD FOR ROLLING BEARING UNDER PLANETARY MOTION

摘要

PROBLEM TO BE SOLVED: To provide a dynamics analyzing method capable of executing relatively simply a dynamics analysis for a rolling bearing under a planetary motion, and capable of contributing to solution of quality problems in various rolling bearing components represented with the damage of a holder.;SOLUTION: This dynamics analyzing method conducts the dynamics analysis for the rolling bearing 9, in a planetary gear mechanism wherein a planetary gear 1 meshed with an external sun gear 3 and an internal gear 2 is supported rotatably to a carrier 7 via the rolling bearing 9. The method uses a model wherein a degree of freedom of the motion of the each constitutive component in the planetary gear mechanism is limited within a radial plane, wherein angular velocities of the rotation of the planetary gear 1 and the rotation of the carrier 7 are made constant, and wherein the center positions of the carrier 7 and the external sun gear 3 are fixed to the center of the internal gear 2, as a dynamics analyzing model of the planetary gear mechanism. A load acting on the rolling bearing 9 is simulated by expressing a transmission torque of the planetary gear mechanism with a revolution-radial-directional load of the planetary gear 1, in the dynamics analyzing model.;COPYRIGHT: (C)2008,JPO&INPIT
