Abstract

The invention discloses an anti-backlash gear structure. The anti-backlash gear structure comprises a driving gear and a first anti-backlash gear meshing with the driving gear. A second anti-backlashgear capable of coaxially rotating is arranged at one end of the first anti-backlash gear, a turbine structure is arranged on the second anti-backlash gear, a worm structure capable of rotating is arranged on the first anti-backlash gear, spiral teeth matched with vortex teeth of the turbine structure are arranged at one end of the worm structure, and a phase angle adjusting mechanism is arrangedat the other end of the worm structure. The anti-backlash gear structure is insensitive to temperature change, and can well ensure the effect of eliminating gear meshing backlash; and the structure issimple, the size is small, occupied space is small, friction pairs are few, and efficiency is high.

Description

technical field [0001] The invention relates to gear transmission technology, more specifically, it relates to an anti-backlash gear structure. Background technique [0002] In the prior art, for example, the patent No. CN201410019294.2 is an industrial robot joint gapless transmission mechanism. This patent uses multi-stage cylindrical gears and two sets of worm gears to drive, and changes the relative rotation direction of the gears to generate opposite torque to eliminate gears. Clearance, its structure is complicated, takes up a large space, and the multi-stage transmission has many friction pairs, and the transmission efficiency is low. [0003] For example, the patent No. is a gear device of CN200580007835.9. The anti-backlash gear of this patent is composed of two aligned gears. Each gear plate has an aligned hole, and there is a "C"-shaped spring element in the hole. The hole is divided into There are two arcuate slots for two parts, each slot accommodates part of t...
