Non-friction type transmission pair capable of separation and joining

Abstract

The invention discloses a non-friction type transmission pair capable of separation and joining. The transmission pair comprises a primary rotating part, a secondary rotating part and a transmission part. The primary rotating part and the secondary rotating part are arranged together coaxially in a sleeved mode and are matched in a rotating mode. Wheel teeth are arranged on the rotating matching face of the secondary rotating part. The transmission part comprises a floating block which is arranged on the rotating matching face of the primary rotating part in a floating mode in the radial direction and is in meshing transmission with the wheel teeth. The tangential direction angle of the action points of the floating block and the wheel teeth is continuously changeable. The primary rotating part and the secondary rotating part are in separation-and-joining transmission through the transmission part. The tangential direction angle of the action points of the floating block and the wheel teeth is continuously changeable in a certain range, continuously-changeable joining force is generated, when the tangential direction angle is large, equal-torque output can be achieved, torque transmission capacity is high, the application range is wide, meanwhile, the floating block and the wheel teeth are matched in a non-friction mode, the problem that due to part abrasion, maintaining is frequent, and service life is short can be avoided, and operation cost is lowered.

Description

technical field [0001] The invention relates to a transmission pair, in particular to a non-friction clutchable transmission pair. Background technique [0002] At present, clutchable transmission pairs are mostly friction structures, and the clutch transmission is realized through the engagement and separation between the active friction plate and the driven friction plate, such as the clutch and brake of the vehicle, and these devices are in the driving process of the vehicle. Frequent operations are required to achieve effective control of the vehicle, and with the gradual increase in the number of vehicles, the smoothness of road traffic is getting worse and worse, and the operating frequency of clutches and brakes is increased, resulting in serious wear of the friction plates, requiring maintenance Frequent, but the replacement and installation of the friction plate is difficult, the operating cost is high, and the service life is short. [0003] Therefore, in order to...

[0002] At present, clutchable transmission pairs are mostly friction structures, and the clutch transmission is realized through the engagement and separation between the active friction plate and the driven friction plate, such as the clutch and brake of the vehicle, and these devices are in the driving process of the vehicle. Frequent operations are required to achieve effective control of the vehicle, and with the gradual increase in the number of vehicles, the smoothness of road traffic is getting worse and worse, and the operating frequency of clutches and brakes is increased, resulting in serious wear of the friction plates, requiring maintenance Frequent, but the replacement and installation of the friction plate is difficult, the operating cost is high, and the service life is short

[0003] Therefore, in order to solve the above problems, a non-friction clutchable transmission pair is needed to avoid the problems of frequent maintenance and short life due to component wear, and reduce operating costs.
