Abstract

The present invention relates to the technical field of mechanical self-locking structures, in particular to a planetary backstop, which includes a cylinder body in which a shaft sleeve I, a locking piece and a shaft sleeve II are sequentially set, one end of the locking piece and the shaft sleeve II The sleeve is fixed, one end of the locking piece is set on the end of the shaft sleeve I, and the circumference of the shaft sleeve I close to the shaft sleeve II is provided with teeth I; The mounting holes for the connection of the shaft sleeve I and the shaft sleeve II, the frame body is evenly distributed around the center of the circle to open a plurality of grooves, the grooves are connected to the mounting holes, the grooves are provided with wedges, and the side of the wedges away from the shaft sleeve I is provided with Elastic part, the center line of elastic part is perpendicular to the center line of axle sleeve 1, and the both sides of elastic part are respectively provided with ball. The device guarantees the precision requirement of synchronous transmission, realizes the reliability of mechanical self-locking, and at the same time ensures that no mechanical impact occurs when the drive shaft transmission stops, and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of mechanical self-locking structures, in particular to a planetary backstop. Background technique [0002] As a mechanical product with mechanical self-locking function, the backstop can be widely used in electric lifting mechanisms, hoisting mechanisms, turntables and other occasions that require mechanical self-locking. Its basic function is expressed as that when there is a transmission input at the input end, no matter whether it is rotating forward or reverse, the output end also has a synchronous transmission output; when the transmission at the input end stops, the output end also stops synchronously. Neither the reversal nor the reverse can be transmitted to the input end, that is, the mechanical self-locking of the output end can be realized. [0003] Backstop is an evolutionary product of an overrunning clutch. Usually when this product is used, problems such as failure of self-locking function, ...
