Abstract

The invention discloses an adjustable side-gap-free turbine worm reducer. The turbine worm reducer includes a shell in which a containing cavity is formed and which is oppositely provided with two worm holes and two worm gear shaft holes, a worm having the two ends penetrating through the worm holes; a worm gear, and four sets of adjusting devices, the two ends of the rotating shaft of the worm gear penetrate through the two worm gear shaft holes, the worm gear is in meshed connection with the worm, and the four sets of adjusting devices are arranged in the containing cavity, one end of the worm is symmetrically connected with two sets of adjusting devices, and each set of adjusting devices comprises a guide positioner, a guide screw rod, a positioning nut, an adjusting bearing seat and ascrew bearing. The adjustable side-gap-free turbine worm reducer is provided with the four sets of adjusting devices, the four sets of adjusting devices are symmetrically arranged relative to the worm, and the height and the inclination angle of the worm can be adjusted, so that the side gap between the worm and the worm gear reaches zero clearance, and noise and abrasion in the working process are reduced, the worm can be adjusted at any time, so that a zero-gap state is always kept between the worm and the worm gear, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to an adjustable backlash-free worm gear reducer. Background technique [0002] The worm gear reducer is a power transmission mechanism that uses the speed converter of the gear to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque mechanism. In the mechanism used to transmit power and motion, the application range of the reducer is quite wide. It can be seen in the transmission system of various machinery, from ships, automobiles, locomotives, heavy machinery used in construction, processing machinery and automatic production equipment used in the machinery industry, to common household appliances in daily life , clocks and more. Its application ranges from the transmission of large power to small loads. The application of the reducer can be seen in the precise angle transmission. In industrial applications, the reducer ...
