Abstract

The invention provides a crown gear coupling and a gear transmission system comprising the same. The crown gear coupling comprises a sleeve, a crown gear and an annular sealing part, wherein the sleeve comprises a sleeve body and an inner tooth part arranged on the inner circumference surface of the sleeve body; at least one part of the crown gear is arranged in a cavity of the sleeve, the crown gear comprises a bushing body, an extending part and a crowned tooth part, the extending part extends from the first end of the bushing body to the second end of the bushing body, an annular gap provided with an opening is formed between the extending part and the bushing body, the crowned tooth part is arranged on the outer circumference surface of the extending part and engaged with the inner tooth part and can do swinging and axial moving relative to the sleeve, and the outer circumference surface of the bushing body is provided with a first arc-shaped surface protruding outwards; and the annular sealing part is arranged on the outer circumference surface of the bushing body in a sleeving mode, in addition, the first end of the annular sealing part makes contact with the first arc-shapedsurface, and the second end of the annular sealing part is directly or indirectly connected with the sleeve body. Through the scheme, the problem that a crown gear coupling is poor in sealing performance can be solved.

Description

technical field [0001] The present invention relates to the technical field of couplings, in particular, to a drum-shaped tooth coupling and a gear transmission system having the same. Background technique [0002] Couplings are mainly used to connect two shafts (driving shaft and driven shaft) in different mechanisms, and make them rotate together to complete the task of torque transmission. It has a very wide range of applications in mechanical transmission equipment. In the field of rail transit, the coupling is a key component on the rail vehicle bogie, which plays an important role in transmitting the traction load and compensating for the displacement deviation between the motor output shaft and the high-speed shaft of the gearbox. In the high-speed and heavy-load power transmission of rail transit, the coupling must also have the functions of buffering, damping and improving dynamic performance. [0003] There are many types of couplings, usually according to the rel...
