A kind of hard tooth surface gear transmission reducer

Abstract

The invention discloses a gear transmission reducer with hard tooth surface, which includes a box body, and the inside of the box body is respectively provided with a first-stage deceleration and a second-stage deceleration, the first-stage deceleration includes an input shaft, and the input shaft The outer bearing is rotatably connected with the box, and the outer fixed sleeve of the input shaft is provided with an input pinion gear, and the input pinion gear is connected with an input bull gear. The present invention relates to the technical field of reducers. This kind of hard tooth surface gear transmission reducer can effectively solve the problem that in the prior art, the gears in the transmission hard tooth surface gear reducer all adopt straight teeth or helical teeth, and the helical teeth will generate axial force during transmission. The meshing and wear between the acceleration gears will reduce the service life of the gear reducer. When the straight teeth directly contact and bite, they will vibrate. The collision force is relatively direct, the force range is shorter than that of the helical teeth, and the torque is also small, especially in long-term continuous operation. After use, the wear of the tooth surface leads to the problem of reduced accuracy.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a hardened gear transmission reducer. Background technique [0002] The gear reducer is an independent closed transmission device between the prime mover and the working machine, which is used to reduce the speed and increase the torque to meet the needs of the work; the gear reducer is a combination of a reduction motor and a large reducer, without coupling It has a compact structure and the load is distributed on the planetary gear, so the bearing capacity is higher than that of the general helical gear reducer, which meets the needs of high torque output in a small space. [0003] The gears in the transmission hard-tooth surface gear reducer are all straight teeth or helical teeth. The helical teeth will generate axial force during transmission, which will accelerate the meshing wear between the gears and reduce the service life of the gear reducer. Vibration will occur, the...

Problems solved by technology

[0005] Aiming at the above-mentioned shortcomings existing in the prior art, the present invention provides a hardened gear transmission reducer, which can effectively solve the problem that in the prior art, the gears in the transmission hardened gear reducer all adopt straight teeth or helical gears. Tooth and helical teeth will generate axial force during transmission, and the meshing wear between the accelerated gears will reduce the service life of the gear reducer. When straight teeth directly contact and bite, vibration will be generated. The collision force is more direct, and the force range is wider than that of helical teeth. It is short and bears a small torque, especially after a long period of continuous use, the wear of the tooth surface leads to the problem of reduced accuracy
