Abstract

The invention discloses a cam type stepless speed change method and a transmission. Two groups of end face circular groove cam crank stud transmission pair are stacked together in parallel in a staggering manner, speed regulation is realized through regulating an offset of the center of an end face disc cam to the center of a primary gear main shaft, a control mechanism is operated to correct and filter the speed regulation and speed change of a speed change mechanism with an end face circular groove cam, the disadvantage operation speeds of an upper starting point and a lower starting point of the end face circular groove cam crank stud transmission pair and adjacent low velocity low efficiency operating areas are eliminated, the advantage operating speeds of high speed high efficiency areas are reserved, so that the efficient balanced variable transmission of the transmission is realized, when the speed is regulated and changed, the inertia moment of a balancing mechanism is synchronously regulated, and the mechanical vibration which is generated by offset variation is eliminated; and finally, the power is output through the speed collection of a crank gear ring pair with a unidirectional bearing.

Description

technical field [0001] The present invention relates to a mechanical transmission mode and device, especially a continuously variable transmission mode and device; it is mainly used in automobiles, rolling stock, ships, construction machinery, agricultural machinery, mining machinery, light textile machinery and aerospace machinery Equipped with continuously variable speed. Background technique [0002] In the current mechanical engineering, speed change is a mechanical transmission method that is often used. The speed change is mainly realized through the transmission; gearboxes and continuously variable transmissions. [0003] With the continuous improvement of technology, continuously variable transmission is more and more widely used; the so-called continuously variable transmission refers to a transmission system that can continuously obtain any transmission ratio within the transmission range. The best match between the drive train and the engine operating conditions...
