Problems solved by technology

Chinese patent application No. 200310101149.0 discloses a mechanical continuously variable transmission with an incomplete gear device, but the processing of the incomplete gear is complicated, and there is a sudden change in speed when entering and exiting meshing, causing rigid impact, which is not suitable for high-speed transmission
These weaknesses of the above-mentioned continuously variable transmission have restricted its development and popularization

Abstract

This invention refers to a active tooth stepless speed variator, which contains two connected slotted wheels, active tooth whose two ends are located in slots of two slotted wheels, the eccentric worm wheel and restriction ring restrict the active tooth to make circle motion using the center of eccentric hole of eccentric worm wheel to change the position of large and small end of output cone for changing effective transmission radius.

Description

technical field [0001] The invention relates to a continuously variable transmission, and in particular to a movable tooth continuously variable transmission. Background technique [0002] With the advancement of science and technology, more and more power devices are used in various fields such as machinery, electric power, transportation, industrial and agricultural production, among which speed change equipment is an indispensable and important part. Among them, transmissions can be divided into fixed ratio transmissions and continuously variable transmissions according to their functions. And with the development of the industry and the improvement of the automation of the production process, the continuously variable transmission, as an important transmission mechanism, has been widely used at home and abroad after years of development. [0003] Due to its high precision and complete control system, the friction continuously variable transmission is used in middle and ...
