<p><P>PROBLEM TO BE SOLVED: To provide a rolling element behavior measuring method for rolling bearing with which a rolling element behavior can be measured without affecting a behavior of a rolling bearing in processing for measurement and the rolling element behavior can be measured as it is even for a completed rolling bearing after building-up. <P>SOLUTION: A method for measuring a behavior of a rolling bearing 1 is provided in which a central portion of a roller 7 watched from a bearing axis direction can be observed from the outside of the bearing without being hidden by a holder 8 at all the time. Marks M1-M4 are applied to an end face of a rotary shaft 9 to which an inner ring 5 of the rolling bearing 1 is fitted and to an end face of the roller 7 of the rolling bearing 1 and while rotating the rotary shaft 9, the marks M1-M4 are imaged by a video camera. Rotation speeds of the rotary shaft 9 and the roller 7 are calculated from a trajectory of the marks M1-M4 obtained from the captured images. Furthermore, a slip ratio of the roller 7 is calculated with the determined actual rotation speed of the rotary shaft 9 as a criterion. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
