Abstract

The invention belongs to the field of the transmission, and relates to a less differential gear reducer with an adjustable gap. The less differential gear reducer comprises a transmission shell and two inner gears which have changeable tooth thickness and are arranged in the transmission shell through a gap adjusting module; the inner gear is engaged with an outer gear which has adjustable tooth thickness and is arranged in the inner gear to form a transmission pair; a small gap is formed between the outer gear and a pin shaft bracket, so that the outer gear is not in contact with the pin shaft bracket, and the outer gear is connected with the pin shaft bracket through a pin shaft column penetrating through the outer gear; and the inner side of the outer gear is connected to an input crankthrough a bearing. According to the reducer, the transmission requirements of no return difference and high precision of less differential gear planetary gear transmission are achieved, the gear backlash caused by manufacturing error, installation error and working wear of a transmission device can be compensated and eliminated, and thus the precise transmission without backlash and return difference is achieved.

Description

technical field [0001] The invention belongs to the field of transmission, and relates to an adjustable backlash and small tooth difference reducer. Background technique [0002] N-type small-tooth differential transmission is widely used in various fields of industry because of its high transmission ratio, compact structure and strong load capacity due to the large number of meshing teeth at the same time. However, with the development of production technology and a series of precise positioning requirements The needs of advanced equipment and instruments, such as medical equipment, robots, military equipment, etc., so there are more stringent requirements for the accuracy of the transmission and the hysteresis control of the transmission. To achieve zero backlash transmission, an anti-backlash device must be introduced, and the anti-backlash device can ultimately determine the precision of the entire reduction gear. However, most of the anti-backlash devices will affect t...
