フレキシブルパッド軸受の静特性

抄録

A flexible pad bearing was developed as a highly stable bearing. This bearing has a monolithic construction with a pad and a web which supports the pad. Therefore, manufacturing the bearing is easy, and the flexible pad bearing is superior in durability. However, the static and dynamic characteristics, which indicate characteristics of load capacity, the coefficient of friction and stability, in the flexible pad bearing have not been completely obtained because the bearing has no time from development. In this paper, the static characteristics of the flexible pad bearing were studied theoretically. Consequently, the flexible pad bearing was found to be suited for use with light loads and at high speeds. Furthermore, at lower eccentricity ratio, it was found that the load capacity of a flexible pad bearing with a thinner web is larger than that with a thicker web, and that the coefficient of friction in a flexible pad bearing with a larger preload factor is smaller than that with a smaller preload factor.
