Worm and gear gap adjusting mechanism

Abstract

The invention relates to the technical field of reducer production, in particular to a worm and gear gap adjusting mechanism. The worm and gear gap adjusting mechanism comprises a bearing seat and ischaracterized in that the bearing block comprises a connecting section and a threaded section, the connecting section is fixedly connected with the worm through a bearing, the threaded section is located at one end of the bearing seat far away from the worm, the outer side of the threaded section is provided with a locking disc for preventing the worm from axially moving, the locking disc is annular, the locking disc is in threaded connection with the bearing seat, a locking notch which is parallel to the surface of the locking disc is formed in the annular end surface of the locking disc, a fastening screw for compressing the locking notch is arranged on the axial end surface of the locking disc, and the clamping force of the fastening screw to the locking notch is used for locking the thread between the locking disc and the bearing seat. The gap of the worm and gear is adjusted through the clamping groove in the bearing seat, and the bearing seat is locked through the matching of thelocking disc, the locking notch and the fastening screw, so as to prevent the worm from axially moving, the gap adjustment of worm and gear and axial locking of worm are realized.

Description

technical field [0001] The invention relates to the technical field of reducer production, in particular to a worm gear clearance adjustment mechanism. Background technique [0002] The reducer is a relatively precise machine, which is used to reduce the speed and increase the torque to meet the work needs. Commonly used angular reducers are prone to vibration and noise due to the existence of the gap between the worm gear and the worm after a long running time, which accelerates the wear of the worm gear. [0003] See the Chinese utility model authorized patent, the authorized announcement number is 206129991U, and the authorized announcement date is April 26, 2017, which discloses a worm gear reducer, including a casing (1) and a worm ( 2), bearings (3) are connected between the box (1) and the position close to both ends of the worm (2), characterized in that: the box (1) is provided with a drive bearing (3) The end surface drives the worm (2) so that the end surface of...

Problems solved by technology

[0004] The worm gear and worm reducer disclosed above can only limit the axial position of the worm, but cannot adjust the axial clearance of the worm gear, so that the worm gear and the worm are meshed and connected with the teeth with the smallest gap, and can be adjusted to prevent the worm from occurring. to move
