Small diameter slewing rings for precision tasks: slewing bearings offer an elegant solution to both large and small applications says mike purchase of Kaydon, who are represented in the UK by Ra Rodriguez

摘要

Slewing rings are thin hoops - large diameter bearings with large bores designed to support axial, radial and tipping force loads Most likely-it will-be heavy-section, low precision applications that spring to mind immediately, but modern designs are capable of much more: Improved manufacturing methods and design concepts are permitting their use in increasingly small, sophisticated and precise applications, Both ball and crossed-roller configurations are common, The direction and degree of loading - especially tipping load -mounting arrangements and performance requirements all determine which design is most appropriate, To combine the function of a bearing and gear, often teeth are cut into the inner or outer race to either rotate with the assembly or remain stationary with respect to ground during operation.
