Abstract

The invention discloses a friction circular plate type gear shifting mechanism which aims at solving the problem that continuously variable transmission cannot be achieved through gear transmission in the prior art. The friction circular plate type gear shifting mechanism comprises a frame and also comprises a driving shaft, a driven shaft and a lead screw; the driven shaft is parallel to the driving shaft; the lead screw is arranged between the driving shaft and the driven shaft; one end of the driving shaft is provided with a detachable first circular plate; one end of the driven shaft is provided with a detachable second circular plate; the first circular plate and the second circular plate are arranged in a parallel eccentric mode; concave pits are distributed in the first circular plate and the second circular plate densely; the lead screw is provided with a transmission wheel which is connected with the lead screw through a sleeve; the sleeve is driven by the transmission wheel to rotate; the sleeve can move along the lead screw; the transmission wheel is connected with the first circular plate and the second circular plate; the transmission wheel can move between the first circular plate and the second circular plate; the outer edge of the transmission wheel is provided with non-slip texture. According to the friction circular plate type gear shifting mechanism, the structure is simple and the continuously variable transmission can be achieved.

Description

technical field [0001] The invention relates to the technical field of speed change, in particular to a friction circular plate speed change mechanism. Background technique [0002] The transmission mechanism is commonly used in machine tools, and the transmission mechanism is more commonly used for gear transmission. However, due to the fixed number of gear teeth and fixed transmission ratio, the gear transmission cannot realize infinitely variable or even multiple variable speeds. Contents of the invention [0003] The present invention intends to provide a friction circular plate speed change mechanism to solve the problem that the gear transmission cannot be infinitely variable in the prior art. [0004] The friction circular plate transmission mechanism in this program includes a frame, a driving shaft, a driven shaft parallel to the driving shaft, and a screw rod arranged between the driving shaft and the driven shaft. One end of the driving shaft is provided with a ...
