MATHEMATICAL MODEL TO SIMULATE AXIAL STIFFNESS IN AXIAL PRELOADED SLEWING RINGS WITH DUPLEX RINGS UNDER AXIAL LOAD
Abstract
There are many cases when the large dimensions slewing rings have to assure an initial preload or a small negative clearance. In this case a useful solution is to create and control the preload using a “preload gap” between the duplexes races. In this paper, an external ring from a slewing ring is machined from 2 distinct parts as a sum of a duplex rings.
