Abstract

The invention relates to a gapless flexible transmission mechanism which is mainly formed by a lead screw, a screw nut matched with the lead screw, a circumferential rotating device and a plurality of flexible strips. The screw nut is arranged on the lead screw. The two ends of one side of the screw nut are respectively provided with a fixed support. The circumference of the circumferential rotating device is provided with two pin seats. The flexible strips are symmetrically and oppositely connected between the screw nut and the circumferential rotating device. The two ends of the flexible strips are connected to the fixed supports of the screw nut and the pin seats of the circumferential rotating device respectively. According to the gapless flexible transmission mechanism, reciprocating motion of the circumferential rotating device within a certain angle is achieved through bidirectional tensioning of the flexible strips. The flexible strips have tensioning characters, so motion stagnation and return difference will not occur. The gapless flexible transmission mechanism has the advantages of being simple in structure, high in transmission ratio, high in transmission accuracy, low in noise and long in service life.

Description

technical field [0001] The invention relates to a transmission mechanism, in particular to a gapless flexible transmission mechanism for transmitting motion and power between two interlaced shafts. Background technique [0002] The mechanical transmission mechanism can change the way, direction or speed of the movement provided by the power, and is used purposefully by people. The current mechanical transmission mechanism mainly includes rack and pinion transmission, chain transmission, belt transmission and worm gear transmission. The belt drive is composed of a driving wheel, a driven wheel and a belt tensioned on the two wheels. It has the advantages of stable transmission, low noise and simple structure. However, the belt drive cannot maintain an accurate transmission ratio because the belt slips during work. Hysteresis is generated, the transmission efficiency is low, and the belt life is short; the chain transmission can ensure a more accurate transmission ratio, but i...
