Abstract
A method and apparatus are provided for measuring the load measuring rolling element deformity of rolling element bearings as a result of applied loads by providing a load measuring rolling element in a bore of a rolling element bearing, defining a fluid cavity about a central shaft and first and second end seal means. The fluid cavity is in continuous communication with a fluid conduit, the fluid conduit in communication with an external volumetric liquid measuring means. When the rotating bearing is placed under dynamic loading, the rolling element will distort and the applied load is a function of the amount of distortion of the rolling element, i.e., the fluid cavity thus producing a correlated volumetric change of the amount of fluid contained in the fluid cavity. The load measuring apparatus is calibrated to provide the measurement of three-dimensional loading and averaging of loading along the rotating bearing axis.
