BEARING LOAD MEASURING APPARATUS

摘要

There is provided load measuring apparatus for determining loads applied to a rolling element bearing. A rolling element of such a bearing is provided with a substantially centrally disposed cavity within which is supported sensing means adapted to monitor a dimension of said cavity. When a bearing is loaded, the rolling elements will distort and the applied load is a function of the amount of distortion of the rolling elements. The load measuring apparatus is calibrated to provide the load from the output of the sensing means.
