Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clutches, in particular to an outer planetary wheel one-way clutch. Background Art
[0002] A one-way clutch is a single-direction transmission mechanism. When the power source is driving the passive element, the transmission is in one direction only. If the power source changes direction (e.g., from clockwise to counterclockwise), the passive element ceases to transmit power. Planetary one-way clutches are widely used in construction machinery due to their simple structure and high load capacity.
[0003] For example, the authorization announcement number "CN107956817B" is named as the alien wheel one-way clutch. Although the alien wheel raceway surface and the spring block are made into a separate type, the alien wheel raceway surface is not constrained by the spring block and can be milled and ground at will, completely solving the problems of machining accuracy and surface quality of the existing structure raceway surface. At the same time, it can be processed by existing ordinary milling machines and grinding machines, with high production efficiency, low processing cost, and easy to achieve mass production. However, multiple baffles are connected to the alien wheel separately, and the baffles are not a whole, resulting in unstable installation of the baffles, shortening the service life of the one-way clutch; at the same time, the extended installation part of the folding spring is squeezed by the alien wheel and the baffle for fixing, which will cause the folding spring to be unevenly stressed and offset, resulting in a weakened elastic effect of the folding spring.
