概要
- 論文の詳細を見る
A two-dimensional analysis is presented for the dynamic performance of spiral groove spherical thrust bearings. The analysis is carried out to obtain the dynamic stiffness and damping factor for the case of vertical and translatory oscillations and the reaction forces of the film in the case of whirl motion. The analysis is restricted to the case where the centers of the rotating and stationary spheres coincide. New equations based on the narrow groove hypothesis are derived and numerical examples are presented. The results are compared with those of the two-dimensional analysis to demonstrate the accuracy.
