<p>PURPOSE: To use a sealing ring sold on the market ignoring the demand of space of bearing structure and rotation movement scanning by arranging an angle encoding means in a sealing retention ring having a sealing ring fixed on the bearing orbit ring. CONSTITUTION: A tooth 20 is machined on a outer circumference of a sealing retention ring 6 as an angle encoding means, and is arranged with a little space to the tooth 21 from the A direction of the arrow sign and oppositely to the sensor 22. The sensor 22 is, for example, an induced action type, and it resolves accelerating speed or reducing speed based on the signals generated while the tooth 21 passes by it and changes them to the controlling signals or regulation signals for a drive arrangement or a brake arrangement. By this constitution, it is not necessary to add or specially arrange an element equipped with an angle code means for detecting the revolution, and it can be used as a retention means of the sealing ring 10. Therefore, a sealing ring sold on the market can be used ignoring the demand of space of the bearing structure and rotation movement scanning.</p> |
