Transmission device for changing straight reciprocating motion into rotary motion

Abstract

The invention discloses a transmission device for changing straight reciprocating motion into rotary motion. The transmission device for changing the straight reciprocating motion into the rotary motion comprises a first lever mechanism, a second lever mechanism, a rocker sliding block mechanism, a one-way clutch, a bevel gear mechanism and a spur gear mechanism. The first lever mechanism comprises a first transmission lever, a first sliding block and a sixth sliding block, the second lever mechanism comprises a second transmission lever, a second sliding block and a seventh sliding block, the rocker sliding block mechanism comprises a fifth sliding block, a connecting rod and a rocker, the bevel gear mechanism comprises a driving bevel gear and a driven bevel gear, and the spur gear mechanism comprises a driving spur gear and a driven spur gear. The transmission device for changing the straight reciprocating motion into the rotary motion can change the straight reciprocating motion into the rotary motion in a small space and is adjustable in rotation speed.

Description

technical field [0001] The invention relates to a transmission device for converting linear reciprocating motion into rotary motion. Background technique [0002] At present, the common mechanisms for converting linear reciprocating motion into rotary motion include rack and pinion, crank slider, ball screw and other mechanisms. Although the rack and pinion mechanism has high efficiency, it requires high installation accuracy and is relatively laborious. The crank-slider mechanism must have a dead point, and the force applied to the crank at different angular positions varies greatly. When the ball screw ball sleeve drives the screw, the energy loss is large, it is easy to slip, and the price is relatively high. Contents of the invention [0003] In order to overcome the problems of large volume, high installation precision requirements, difficult installation, large energy loss, easy slipping and high price existing in the existing mechanism, the present invention provi...
