This machine comprises a shaft which is along a prescribed axis, a bearing which bears the shaft, a lubrication chamber which contains the shaft and the bearing and which can store a fluid lubricant, and three through-holes which each pass through a wall surface of the lubrication chamber and which can be opened, wherein: two through-holes (for example, a through-hole or a through-hole) among the three through-holes open to respective spaces on both sides of the lubrication chamber in the axial direction with the bearing sandwiched therebetween; when the lubricant is introduced, at least one of the two through-holes is open as a lubricant introduction hole; and when the lubricant is drained, the two through-holes are open as ventilation holes, and the remaining through-hole (for example, a through-hole) is open as a lubricant drainage hole.

A preloaded ball bearing assembly includes a primary bearing assembly disposed between a rotating component and a static structure. The assembly also includes a preload bearing assembly disposed in contact with the rotating component. The assembly further includes a flexible support disposed between the primary bearing assembly and the preload bearing assembly.

A squeeze film damper bearing device includes an inner race that is fitted around an outer periphery of a rotating shaft, an outer race that is supported via an annular space on an inner periphery of a bearing sleeve provided on a bearing retaining member, the annular space forming a squeeze film, and a plurality of rolling bodies that are disposed between the inner race and the outer race. The bearing sleeve is formed from a plurality of sleeve elements that are divided in a peripheral direction, and the plurality of sleeve elements move in a radial direction so as to be capable of changing a height in the radial direction of the annular space.

A pressure plate bearing device assembled by quick connection includes a bearing and a pressure plate. The pressure plate includes a sleeving hole which sleeves outside an outer race of the bearing, a limiting groove provided in a position where the outer race of the bearing is nested in the sleeving hole in a matching manner, and a steel ball arranged in the limiting groove. Based on the limiting match between the steel ball and the sleeving hole and that between the steel ball and the outer race of the bearing, at least the axial limit between the bearing and the pressure plate is at least fulfilled. The outer race of the bearing or the pressure plate is provided with a mounting channel that is in communication with the limiting groove. The pressure plate bearing device assembled by the quick connection is more easily assembled and reliably connected.
