Document Type and Number:
Japanese Patent JP2005156499
Kind Code:
A
Abstract:
To provide a multiple rotation absolute position detector with a simple structure.
In this multiple rotation absolute position detector arranged in a speed reducer 8, a bearing with a rotation sensor is used for a bearing 4 supporting an output shaft 2 among bearings 3 and 4 supporting an input shaft 1 and the output shaft 2 in the speed reducer 8. The bearing 4 with the rotation sensor is provided with a rolling bearing part 5 and a rotation sensor 6 for detecting a rotational position between races 5a and 5b on the fixed side and the rotational side in the rolling bearing part 5.
