Hard tooth surface gear transmission speed reducer

Abstract

The invention discloses a hard tooth surface gear transmission speed reducer which comprises a box body. A first-stage speed reducer body and a second-stage speed reducer body are arranged in the box body, the first-stage speed reducer body comprises an input shaft, the input shaft is rotationally connected with the interior of the box body through a bearing arranged at the outer side of the input shaft, and the outer side of the input shaft is fixedly sleeved with an input small gear; and the input small gear is in transmission connection with an input large gear. The invention relates to the technical field of speed reducers. The hard tooth surface gear transmission speed reducer can effectively solve the problems that in the prior art, straight teeth or helical teeth are adopted for gears in the transmission hard tooth surface gear speed reducer, the helical teeth can generate axial force during transmission, meshing abrasion between the gears is accelerated, the service life of the gear speed reducer is shortened, vibration is generated during direct contact and meshing of the straight teeth, collision stress is relatively direct, the stress range is shorter than that of the helical teeth, borne torque is small, and particularly after long-time continuous use, tooth surface abrasion leads to reduction of precision.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a hardened gear drive 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 work needs; the gear reducer is a combination of a geared motor and a large reducer without coupling The gear and adapter are compact, and the load is distributed on the planetary gear, so the load capacity is higher than that of the general helical gear reducer, which meets the needs of small space and high torque output. [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. When the straight teeth directly contact ...

AI Technical Summary

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
