Problems solved by technology

[0002] In transmission design, due to special requirements, such as mechanism self-locking, large transmission ratio, etc., it is necessary to use worm gear transmission. Now the fixed center distance is generally used to design the worm gear transmission structure. In order to achieve high transmission accuracy, each structural part is processed High precision requirements lead to high processing costs, and if the processing accuracy requirements are lowered, there will be backlash in the meshing state of the worm gear, so that the transmission accuracy will be reduced

Abstract

The invention discloses a worm and gear transmission structure. The worm and gear transmission structure comprises a mounting seat, a motor, a worm and a gear, wherein the worm and the gear are matched with each other, the output end of the motor is connected with one end of the gear, the worm is rotatably arranged on the mounting seat, the motor is movably arranged on the mounting seat, and the worm and gear transmission structure further comprises an elastic part, a first bearing and a bearing seat; and the first bearing sleeves the other end of the gear and fixed to the bearing seat, one end of the elastic part is connected with the mounting seat, and the other end of the elastic part is connected with the bearing seat so as to drive the gear to be close to the worm. Under the action of the elastic part, the worm and the motor can deflect by a certain angle, so that the center distance of the worm and the gear is automatically adjusted, zero-meshing backlash transmission of the worm and the gear is achieved, and the transmission precision of the worm and the gear is effectively guaranteed; and due to the fact that the center distance of the worm and the gear can be automatically adjusted, the machining precision requirement of the worm and the gear can be lowered, and the manufacturing cost of the worm and gear transmission structure is reduced.

Description

technical field [0001] The invention relates to the technical field of transmission structures, in particular to a worm gear transmission structure. Background technique [0002] In transmission design, due to special requirements, such as mechanism self-locking, large transmission ratio, etc., it is necessary to use worm gear transmission. Now the fixed center distance is generally used to design the worm gear transmission structure. In order to achieve high transmission accuracy, each structural part is processed High precision requirements lead to high processing costs, and if the processing precision requirements are lowered, there will be backlash in the meshing state of the worm gear, so that the transmission precision will be reduced. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a worm gear transmission structure with high transmission precision and low processing cost. [0004] In order to solve the a...
