Tu's high-sensitivity overrunning clutch

Abstract

The invention relates to a Tu's high-sensitivity overrunning clutch which comprises an external star wheel and an internal star wheel; the external star wheel or the internal star wheel is provided with a logarithmic helix groove structure; a roller, an ejector block and a spring are positioned in the groove structure; the groove is provided with a tooth groove for mounting the ejector block and the spring; the tooth groove is arranged in an inclined manner with a certain angle with the shafts of star wheels; and the roller is of a sectional structure, and separated sheets are arranged among all sections of roller. The roller, the ejector block and the spring are arrayed outwards or inwards in an inclined manner along the axial direction of the external star wheel or the internal star wheel at a certain angle, the perimeter distance occupied by the ejector block and the spring is shortened, and more rollers can be arrayed, thus the torque born by the rollers is increased greatly; by adopting the sectional multi-roller arrangement, the rollers hardly incline or deviate, and high sensitivity is achieved; the stress is uniform, the surfaces of the rollers and the star wheels are difficult to damage; and compared with the traditional roller-type overrunning clutch, the Tu's high-sensitivity overrunning clutch provided by the invention has higher sensitivity, can transfer greater maximum torque, and simultaneously has higher stability and longer service life.

Description

Technical field [0001] The invention and a high-sensitivity overrunning clutch. Background technique [0002] Traditional roller overrunning clutch, see image 3 , Is to arrange the roller 1, the top block 4, and the spring 5 in parallel along the cylindrical surface of the outer planet wheel 2 or the inner planet wheel 3, thus occupying a limited circumference distance. As a result, the rollers cannot be arranged too much, resulting in a smaller torque that can withstand. [0003] In the traditional roller-type overrunning clutch, the length of roller 1 is the same as the width of the overrunning clutch, and the single roller arrangement of the whole roller is adopted. Therefore, the roller is too long during operation, which is prone to tilt and offset This affects the response sensitivity of the overrunning clutch, and damages the surface of the roller or star wheel due to uneven force, which affects the service life of the overrunning clutch. Summary of the invention [0004] T...

As a result, the rollers cannot be arranged too much, resulting in a smaller torque

[0003] In the traditional roller overrunning clutch, the length of roller 1 is the same as the width of the overrunning clutch, and the single roller arrangement of the entire roller is adopted, so the roller is too long during operation, and it is easy to produce inclination and offset Thus affecting the response sensitivity of the overrunning clutch, and causing damage to the surface of the roller or star wheel due to uneven force, affecting the service life of the overrunning clutch
