Chuck type stepless speed changing mechanism

Abstract

The invention relates to a chuck type stepless speed changing mechanism which comprises a driving belt pulley and a driven belt pulley. Each belt pulley comprises a rotary shaft, a rear mounting base end cover, a front mounting base end cover, spiral discs and chuck plates, each rear mounting base end cover is arranged at one end of the corresponding rotary shaft, and each front mounting base end cover is arranged at the other end of the corresponding rotary shaft. The chuck type stepless speed changing mechanism is characterized in that the spiral discs are arranged on the rear mounting base end covers, positioning tooth spaces which can be meshed with spiral tooth spaces of the spiral discs are arranged on the inner side surfaces of the chuck plates, belt wheels are arranged at the tail ends of the chuck plates, a plurality of belt clamp grooves are spliced with one another to form each belt wheel and are arranged around the axis of the corresponding rotary shaft, and the chuck plates are mounted on plate grooves of the front mounting base end covers, are fixed by the aid of fixing grooves and only can move along the radius directions of the belt wheels. The chuck type stepless speed changing mechanism has the advantages that only the radiuses of wheel discs of the two belt pulleys need to be adjusted, so that a speed regulating ratio of the mechanism can be changed, and speeds can be regulated under the condition that the belt pulleys are not changed; the chuck type stepless speed changing mechanism is flexible in regulating range, and speed regulating tasks under different working conditions can be implemented.

Description

technical field [0001] The invention relates to a continuously variable transmission mechanism, in particular to a continuously variable transmission mechanism composed of adjustable radius pulleys. Background technique [0002] The speed regulating mechanism is widely used in various mechanical equipment such as machine tools, automobiles, water pumps, etc., but the current speed regulating mechanisms are all speed regulating with a fixed speed regulating ratio or jumping between several fixed speed regulating ratios, which cannot realize Flexible speed regulation; some existing stepless speed change mechanisms are complex in structure, difficult to manufacture, and expensive in cost. They are only used in some high-end cars and are difficult to popularize. Contents of the invention [0003] The present invention is to provide a chuck-type continuously variable transmission mechanism, which can change the transmission speed ratio by changing the diameter ratio of the two ...
