A non-impact gear clutch structure

Abstract

The invention discloses a non-impact gear clutch structure, which belongs to the technical field of clutch gears. The non-impact gear clutch structure includes a central shaft, and driving wheels, clutch gears, driving wheels, gaskets, springs, retaining rings inserted on the central shaft in sequence; the central shaft runs through the entire gear clutch mechanism, and the The retaining ring is fixed to the central shaft, the driving wheel is fixed to the central shaft, the spring is arranged between the gasket and the retaining ring; the gasket is arranged in the recess of the driving wheel. The invention is applied to various miniature gear transmission machinery, so that the transmission mechanism can realize clutch protection when the load exceeds a certain level, and solves the problems of frequent impact, loud noise, serious wear and obvious attenuation of the clutch protection threshold in the clutch process of the existing gear clutch mechanism And other problems, it ensures that the clutch threshold will not fail below the rated output torque, which improves the service life and reliability of the entire mechanism.

Description

【Technical field】 [0001] The invention relates to the mechanical field, in particular to an impactless gear clutch structure. 【Background technique】 [0002] In the mechanical structure, especially in the field of gear transmission structure, in order to avoid damage to the motor due to overload, a gear clutch device is used. When the gear reaches a certain load, it can automatically disengage from the transmission to protect the motor. Most of the existing clutch protection mechanisms are not disengagement and engagement in the strict sense. During the working process, the clutch mechanism disengages and occludes frequently alternately, resulting in repeated tooth grinding or grinding, resulting in impact, noise and severe wear; and the alternation of disengagement and occlusion makes the spring repeatedly impact and compressed, the spring rigidity rapidly decays, and the clutch protection threshold is rapid. Reduced, resulting in the gear transmission being unable to outp...
