Abstract

A double worm spur gear anti-backlash transmission device is provided, comprising a main drive worm and a slave drive worm, the main drive worm and the slave drive worm are connected through a pair of meshing gears and installed in parallel in the worm seat, the main drive The worm and the slave drive worm are in mesh with a spur gear, the main drive worm and the slave drive worm rotate in opposite directions, and one end of the slave drive worm is equipped with an anti-backlash locking device. The present invention adopts the design scheme of meshing two involute worms and one involute spur gear, and uses one involute spur gear to replace the two integrated worm gears, which solves the problems of difficult processing of worm gears and inseparable transmission of worm gears , the transmission precision is improved and the installation process is simple.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission, and in particular relates to a double worm spur gear anti-backlash transmission device, which can be used for a servo drive transmission device of a high-precision full-closed-loop numerical control system. Background technique [0002] In recent years, with the continuous development of my country's equipment manufacturing technology in the direction of digitalization, precise and zero-backlash transmission requirements have been put forward for servo-driven transmission devices, especially in semi-closed-loop and fully-closed-loop servo control systems, which are more sensitive to backlash. At present, double worm and worm gear anti-backlash transmission is a widely used transmission form. Its specific structure is generally that the driving worm and driven worm are connected by a pair of meshing pinions, installed in parallel on the worm seat, and the driving worm and driven wor...
