ROLLING-ELEMENT BEARING AND METHOD OF COUNTERING LOAD APPLIED TO ROLLING-ELEMENT BEARING

摘要

A rolling-element bearing includes an inner bearing ring and an outer bearing ring. The inner bearing ring and the outer bearing ring define an axial direction and a circumferential direction. The rolling-element bearing includes a plurality of rolling elements. The rolling elements are configured to roll circumferentially between the inner bearing ring and the outer bearing ring. The rolling-element bearing includes at least one oil chamber. The oil chamber is between the inner bearing ring and the outer bearing ring. Each oil chamber is defined by the inner bearing ring, the outer bearing ring and an oil chamber housing. The oil chamber housing is fixed to one of the inner bearing ring and the outer bearing ring. The rolling-element bearing includes at least one duct corresponding to each oil chamber. The at least one duct is for a supply of oil to the corresponding oil chamber. Each duct extends through the bearing ring to which the oil chamber housing is fixed.
