Abstract

The invention provides a rotary device guaranteeing the axiality of a rotor and a stator of a rotary motor and realizing assembling work of the rotary device efficiently. The rotary device (1) is provided with a motor (100) and a reducer (200). The motor is provided with the rotor (111) and the stator (113). The reducer is provided with an input shaft (211) provided with a roller gear cam (212); and an output shaft (221). The periphery of the output shaft is provided with cam driven pieces (222) clamping with the roller gear cam successively. The output shaft extends along a direction perpendicular to the output shaft. The motor is provided with a rotary shaft (101) fixed with the rotor. The output shaft of the rotary shaft and the reducer are connected coaxially. The motor also includes a bearing support part (140) supporting a bearing (213) and exerting a certain preload to the bearing. The bearing supports the output shaft of the reducer to rotate freely. The rotor is arranged in the bearing support part.

Description

technical field [0001] The present invention relates to a rotary device used as a drive source such as a rotary table device. Background technique [0002] Conventionally, in the field of machine tools, for example, a rotary device including a rotary motor and a reducer has been used as a drive source of a rotary table device serving as a mounting table for workpieces (for example, refer to Patent Document 1). In this rotary device, the rotor of the rotary electric machine is connected to the input shaft of the speed reducer with bolts via a mounting flange. In addition, a roller gear cam is provided on the input shaft of the reducer. In addition, the cam followers provided on the outer periphery of the output shaft engage with the roller cam sequentially, whereby the rotation of the input shaft is decelerated and transmitted to the output shaft. The input shaft and the output shaft are rotatably arranged in the housing so that the axial directions of the respective shafts...
