A variational solution of two lobe bearings
暂无分享,去创建一个
Non-circular bearings are finding extensive use in high speed machinery as they enhance shaft stability, reduce power losses and increase oil flow (as compared to circular bearings), thus reducing bearing temperatures. Elliptical bearings are among the commonly used non-circular bearings. In this paper, a solution using a variational approach has been presented to analyse elliptical bearings. The results of an elliptical bearing actually in use in a 110 mW turbo-set have been compiled.
