Impact-resistant speed changer based on volute spiral spring

Abstract

The invention belongs to the technical field of speed changers and particularly relates to an impact-resistant speed changer based on a volute spiral spring. The impact-resistant speed changer comprises a first shell body, an input shaft, a connection mechanism, an output shaft, a one-way clutch ring, a first shaft, a gear ring, the volute spiral spring and the like. By using the volute spiral spring in the connection mechanism to realize variable speed drive, the speed changer has the beneficial effects that the effect of variable speed is realized through a simple structure; and meanwhile, due to the fact that the pull force provided by the volute spiral spring is continuous, physical impact damage cannot be generated at the moment of gear shifting and speed changing, and in this way, the service life of the speed changer is greatly prolonged. A gear is made to rotate automatically through meshing of a drive tapered tooth and other tapered teeth, and transfer of large torque is realized; and besides, the gear is made to perform revolution around the gear ring under the gear shifting and speed increasing effect of the connection structure, and transfer of a large rotation speed isrealized under the dual effect of automatic rotation and revolution of the gear. The impact-resistant speed changer is simple in structure and has a good use effect.

Description

technical field [0001] The invention belongs to the technical field of transmissions, in particular to an anti-shock transmission based on scroll springs. Background technique [0002] At present, the traditional transmission needs to adjust the output speed suitable for this working condition according to different working conditions during the operation process. The traditional transmission generally performs gear shifting according to the gears in the gearbox. In the process of gear shifting, the main drive gear needs to engage and shift gears between gears of different sizes, then an instantaneous impact force will be generated during the instant meshing process between the main drive gear and another gear, which will affect the teeth of the gear. With a certain impact damage, it is easy to reduce the service life of the gear in the long run, and even the phenomenon of slipping occurs when the gears mesh. In order to avoid the impact damage caused by the instantaneous me...

[0002] At present, the traditional transmission needs to adjust the output speed suitable for this working condition according to different working conditions during the operation process. The traditional transmission generally performs gear shifting according to the gears in the gearbox. In the process of gear shifting, the main drive gear needs to engage and shift gears between gears of different sizes, then an instantaneous impact force will be generated during the instant meshing process between the main drive gear and another gear, which will affect the teeth of the gear. With a certain impact damage, it is easy to reduce the service life of the gear in the long run, and even the phenomenon of slipping occurs when the gears mesh. In order to avoid the impact damage caused by the instantaneous meshing of the gears, it is necessary to design an impact-resistant transmission.
