| Thrust bearing is composed by two or more thrust sheets and more rolling elements. The thrust sheets divide into shaft washer & housing washer, the rolling elements was fixed by the steel or brass cage. Many of thrust bearing is ball thrust bearing Thrust bearings absorb axial loads from rotating shafts into the stationary housings or mounts in which they are turning. Axial loads are those transmitted linearly along the shaft. Good examples of axial loads are the forward thrust on boats or prop-driven airplanes as a result of their propeller's rapid rotation. Thrust bearings are also used in power drills, where the user puts their weight into a rotating bit to drill through tough materials. Merry-go-rounds have massive thrust bearings to support all the rotating weight. Pure thrust bearings are so termed because they only resolve axial forces from the rotating component into their mounting and not radial forces. As in other types of bearings, there are two major groupings of these bearings, sliding bearings and rolling bearings. An example of a sliding thrust bearing is a thrust washer which is a low-friction material between the shaft and the bearing journal along the rotating component. Types of rolling thrust bearings are ball thrust bearings, and specialized tapered roller bearings. |
