Integrally moving friction disk type one-way clutch

Abstract

The invention discloses an overall mobile friction plate type one way clutch, which uses the inner holes of an outer positioning sleeve to position and uses one way friction plate starting shaft which is provided with two transverse alignment sliding bearings. The one way clutch used in high-power starting engine has high coaxiality, high transmission torque, and small inversing drag resistance after starting, good reliability, novel structure and is an innovative product.

Description

Technical field [0001] The invention relates to an improvement of a one-way clutch, which is mainly suitable for high-power deceleration starters. technical background [0002] At present, the concentricity of the traditional roller type one-way clutch used in domestic high-power deceleration starters is relatively poor, and problems such as slipping and moving difficulties are prone to occur. Therefore, some people have proposed improvements to this related technology, for example, Chinese Patent No. CN200420024272.7 Regarding the "new roller type one-way clutch", it is mentioned that there is a drive gear, a guide cylinder, a spring, a roller and a cover plate mechanism. On the inner peripheral surface of the curved cavity at the large end of the guide cylinder, there is a radial Uniformly distributed axial reinforcement, the reinforcement has a step, the roller is placed between the axial reinforcement and the step of the adjacent axial reinforcement and leans against the...

Problems solved by technology

[0002] At present, the concentricity of the traditional roller type one-way clutch used in domestic high-power deceleration starters is relatively poor, and problems such as slipping and moving difficulties are prone to occur. Therefore, some people have proposed improvements to this related technology, for example, Chinese Patent No. CN200420024272.7 Regarding the "new roller type one-way clutch", it is mentioned that there is a drive gear, a guide cylinder, a spring, a roller and a cover plate mechanism. On the inner peripheral surface of the curved cavity at the large end of the guide cylinder, there is a radial Uniformly distributed axial reinforcement, the reinforcement has a step, the roller is placed between the axial reinforcement and the step of the adjacent axial reinforcement and leans against the eccentric arc of the inner circumference of the curved surface cavity at the large end of the guide cylinder On the surface, the spring is placed on the step and its two ends lean against the roller and the axial reinforcement respectively. The cover plate is installed on the spring and the roller, and is connected with the inner peripheral surface of the curved cavity at the large end of the guide cylinder and the driving gear. The outer peripheral surface constitutes the working chamber of the spring and the working chamber of the roller. Its steel reinforcing rib integrated with the guide cylinder can completely replace the existing nylon bracket. The transmission torque of this one-way clutch is increased, but the structure is more complicated. The quality is not stable enough, and the production cost increases
