Method of distributing load among stacked bearings |
摘要 |
A series of axially stacked rolling bearing assemblies for transmitting axial thrust load between relative rotating cylinders, such as in a fluid powered downhole motor, is provided with the bearing races of each assembly formed from a bearing material significantly softer than the balls thereof so as to readily wear to a condition wherein the thrust load is generally equally distributed throughout each assembly within the stack.
