Electromechanical integration nutation oscillating tooth transmission device

Abstract

The invention relates to an electromechanical integration nutation oscillating tooth transmission device, which is characterized in that the nutation oscillating tooth transmission device composed of a fixing disc end cover, a first end cover bearing, a fixing disc, a rotating drum, a nutatoin disc, a rotating disc end cover, a second end cover bearing, a rotating disc, an outer end cover and an output shaft is installed in a box body. A bearing and the rotating drum are arranged on the outer lateral face of the nutation disc, and a motor composed of a rotor, a permanent magnet and a stator is installed along the outer lateral face of the rotating drum to achieve engagement of a roller of the nutation disc and teeth of the fixing disc, engagement of the roller of the nutation disc and teeth of the rotating disc and achieve the fact that a bolt and an output shaft fixedly connected with the rotating disc output torque. The electromechanical integration nutation oscillating tooth transmission device is novel and unique in design and compact in structure, has the advantages of no contact, small vibration and overload protection due to utilization of magnetic force transmission, avoids the fact that an inclined shaft section in the nutation oscillating tooth transmission device is difficult to machine, is capable of remarkably prolonging service life of a rotating arm bearing due to the fact that the rotating arm bearing is placed outside the nutation disc and has the advantages of being fewer in part number, high in bearing capability, low in noise, high in efficiency and thelike.

Description

technical field [0001] The invention belongs to a nutating movable tooth transmission device, in particular to an electromechanical integrated nutating movable tooth transmission device. Background technique [0002] As we all know, magnetic transmission uses magnetic coupling to realize the complete separation of the main and driven mechanisms, which can obtain dynamic static sealing, ensure zero leakage, and has small vibration, low noise, simple structure, and good mechanical transmission performance; but magnetic transmission Compared with traditional mechanical gears, worm drives and other transmission devices, the transmitted torque is at an obvious disadvantage. The nutating movable tooth transmission device on the market has the characteristics of compact structure, large transmission ratio range, and strong bearing capacity; after patent retrieval, its patent number is 200510078247.6 A kind of nutating movable tooth transmission device, its structure includes end co...
