Abstract

The present invention relates to a driver for a north seeker. The driver comprises a first input shaft, a first drive member, a second input shaft, a second drive member, a harmonic speed reducer, a damping mechanism and an output shaft, wherein the first drive member and the first input shaft are connected so as to drive the first input shaft, the second input shaft and the first input shaft are concentrically arranged, the second input shaft can rotate relative to the first input shaft, the second drive member and the second input shaft are connected so as to drive the second input shaft, the harmonic speed reducer comprises a first rigid gear, a second rigid gear and a harmonic wave generator, the first rigid gear is fixedly connected with the second input shaft, the harmonic wave generator is fixedly connected with the first input shaft, the damping mechanism performs damping on the second input shaft through friction, the output shaft and the first input shaft are coaxially arranged, one end is connected with the second rigid gear, and the other end is connected with the north seeker. With the driver, the north seeker can meet application environment requirements, and further can meet the full range north seeking requirements.

Description

technical field [0001] The invention relates to a driver, in particular to a driver used in a north finder. Background technique [0002] In the prior art, the north finder is mostly driven by a worm gear transmission. Although the worm gear transmission is used as the driving device of the north finder, although the structure is simple, it cannot meet the requirements of all-round north seeker. In addition, with the continuous improvement of modern automation technology and the degree of automation of electromechanical products, higher requirements are put forward for drives or transmissions in the field of precision machinery. How to improve the degree of automation of drives or transmissions and ensure the reliability of the mechanism is a A research hotspot in the field of precision machinery, especially for the north finder, based on its special application environment, very limited use space and multifunctional requirements, it is more necessary to have a small size, v...
