Load Distribution over Raceways of an 8-Point-Contact Slewing Bearing

Article Preview

Abstract:

An 8-point-contact slewing bearing is usually applied with strict requirements. The load distribution over raceways is the fundament to calculate both the static and dynamic capability of a slewing bearing. The paper discussed a method for calculating the load distribution in an 8-point-contact slewing bearing under general load conditions (turnover moment, axial load and radial load). Based on the method, some suggestions were proposed for optimization of the slewing bearing design.
