Abstract
A device for gauging relative rotational movement and/or displacement between the races (10, 11) of a bearing comprises a pulse generator (13) activated by the rotating race (11) and coupled to a non-rotating sensor (12). The pulse generator consists of a coding wheel and the sensor consists of an optical encoder. The coding wheel (13) comprises a disk of reflecting material on which a plurality of non-reflecting zones or apertures is provided.
Claims6
A device for gauging relative rotational movement and/or displacement between races of a bearing, wherein the bearing comprising:
- a rotating race with a pulse generator means activated by the rotating race;
- and
- a non-rotating race with a non-rotating sensor means mounted to the non-rotating race and coupled to the pulse generator means;
- wherein said pulse generator means consists of a coding wheel mounted to the rotating race of the bearing and said sensor means consists of an optical encoder.
