A swing arm type pulse continuously variable transmission

Abstract

A swing arm type pulse continuously variable transmission includes a transmission part, a speed ratio adjustment part and an output part. An eccentric wheel is fixed on the input shaft of the transmission part, and a rolling bearing is fixedly installed on the outer side of the eccentric wheel, which is rollingly connected with one side of the lower swing arm of the transmission swing arm. They are respectively rollingly connected with one side of the upper swing arm of the transmission swing arm and one side of the output swing arm, and the contact position of the rolling connection can be changed by manually adjusting the speed control handle. The output swing arm of the output part can swing around the axis of the output transmission shaft. There is an output transmission gear on the output transmission shaft. The output transmission gear meshes with the output gear. The output gear is fixedly connected to the output shaft through a key.

Description

technical field [0001] The invention relates to a swing arm type pulsating continuously variable transmission, in particular to a speed adjustment method of the pulsating continuously variable transmission. Background technique [0002] With the rapid development of the economy, people have more and more demands for power in production and life, and the process of power use often involves the need for speed regulation. At present, most of them are realized through multiple sets of gears, but this kind of The gear structure is slow in speed, low in safety, high in energy consumption and easy to wear, and still needs technological innovation; the pulsating continuously variable transmission has the advantages of reliable operation, wide range of speed regulation, and many speed regulation methods. It is currently used in pharmaceuticals, food, and textiles. , chemical industry, light industry, plastics, papermaking and other industrial fields are widely used; CVTs have many te...

Problems solved by technology

However, its speed regulating mechanism has relatively many parts and its structure is relatively complicated.

[0004] The Chinese invention patent application with the application number 89201734.1 discloses a pendulum type pulsating mechanical continuously variable transmission, which is transmitted by means of an eccentric disc and an overrunning clutch. During the speed regulation, it changes with the length of the rack or the crank, the pulsation curve of the output shaft speed changes irregularly, and the mechanical efficiency is low. The relative relationship of the main mechanism remains unchanged when the speed is changed, and the output can work in both forward and reverse directions. The value of the ratio coefficient remains unchanged, the output is stable, etc., but its structure is complex and huge, the manufacturing cost is high, the maintenance is difficult, and the speed ratio adjustment is also difficult, especially it cannot provide a very low speed ratio, such as zero speed ratio.
