Abstract

The invention discloses a transmission device capable of changing reciprocating rotation motion into unidirectional rotation motion. According to the transmission device, a multistage gear transmission mode is utilized, the reciprocating rotation motion of an input shaft is subjected to multistage gear transmission through two unidirectional couplers, and claw wheels of the unidirectional couplers are driven to rotate clockwise or counterclockwise, so that the two unidirectional couplers can rotate clockwise or counterclockwise; therefore, an output shaft always keeps rotating clockwise in spite of counterclockwise rotation or clockwise rotation of the input shaft, so that the unidirectional rotation output of the output shaft is realized; and the device has the characteristics of reciprocating rotation driving and unidirectional rotation output, is widely applied and is particularly suitable for a reversing device of a sea-wave power generation device. The transmission device is low in gear transmission stage number and high in efficiency and has the characteristics of compact structure and high reliability, and high coaxiality of the input shaft and the output shaft can be kept. Compared with the prior art, the transmission device has the advantages that the device has a simple structure, is high in transmission efficiency and high in reliability and is easy to replace.

Description

technical field [0001] The invention belongs to the field of mechanical transmission, and in particular relates to a transmission device for changing reciprocating rotary motion into unidirectional rotary motion. Background technique [0002] At present, most of the devices driven by reciprocating force only use the driving force to do work in one way, while the other one-way does not do work, and only completes mechanical reset, which limits the efficiency and continuity of transmission. The existing bidirectional drive and unidirectional output technology and devices have the characteristics of complex structure, high manufacturing cost, and low reliability. [0003] The invention with the patent application number of 200610041414.4 provides a bidirectional drive, the drive has an internal ring gear, the internal teeth of which mesh with two planetary gears at the same time, one of the planetary gears directly meshes with the one-way gear with movable teeth, and the other ...
