Condition monitoring tool for angular contact ball bearing

This paper deals with condition monitoring of an angular contact ball bearing in high speed at applicable axial loading in rotating systems such as motors or space actuators that nowadays can be found in a variety of consumer products. Some measuring methods of torque in instrument ball bearing in small motors or similar applications have been summarized. All these methods are not suitable for the extremely low torques and depend on dimensions of the systems. Therefore a completely new diagnosis tool for angular contact ball bearing with applied applicable axial loading at high speed, in applicable range is designed and developed. This tool allows us to gauge ball bearing quality and integrity, ensuring that precision specifications are under control, and the maximum efficiency can be gained. Through this tool the user ensures maximum performance of ball bearing by physically diagnosing of irregularities in bearing prior to use. Problems such as retainer hang-up, ball or race surface problems and contamination, can be determined on a bearing through different samplings.
