Analysis of a Planet Bearing in a Gear Transmission System

This paper develops a general theory whereby the effects of the elastic distortions of a planet bearing outer ring due to gear loads and inertial forces on the bearing load distribution and fatigue life can be considered. The analysis makes use of a recently developed solution for a thin elastic ring under an arbitrary system of loads. A numerical example for a planet gear roller bearing under heavy gear loads and operating at a high speed is presented.
