Embodiment Construction

[0006] Two power input shafts drive two cylindrical cams with the same size and shape to rotate at the same speed, the slopes of the two cylindrical cams are installed in parallel, and the follower is installed on two connecting rods that can move up and down. When the cylindrical cam rotates, the follower swings left and right.

[0007] When the rotation speed of the input shaft is constant, the swing speed of the follower will be different depending on the position of the contact point between the universal roller on the follower and the cylindrical cam. When the transmission gear is rotated, the gear drives the transmission rack to move, and the transmission rack moves to drive the connecting rod. Moving up and down changes the contact point between the universal roller on the follower and the cylindrical cam. The farther the contact point is from the center of the input shaft, the greater the swing speed of the follower and the greater the speed of the output gear. The clo...

Abstract

The invention provides a non-friction type cam mechanism continuously variable transmission. A driven part is driven to swing left and right by the rotation of two cylinder cams, and the driven part pushes an output gear to rotate. Continuously variable transmission can be realized within a certain range by moving contact points between the driven part and the cylinder cams. The non-friction typecam mechanism continuously variable transmission has the characteristics of simple structure, compact, non-friction transmission, continuously variable transmission within a certain range, simple speed change process, and low manufacturing cost.

Description

technical field [0001] The invention is a multi-purpose continuously variable transmission, which is mainly applicable to various vehicles, machine tools with speed requirements, textile machinery, light industrial machinery, printing machinery, and mechatronics assembly. Background technique [0002] The continuously variable transmission can realize the continuous change of the transmission ratio, so as to obtain the best match between the transmission system and the engine operating conditions, improve the fuel economy and power of the vehicle, and is suitable for the development of mechanization and automation of the current production process and the improvement of mechanical performance A general transmission device. But today's continuously variable transmission is mainly based on friction cvt gearbox, which cannot bear too much torque by metal belt friction transmission, is easy to slip, has short service life, high failure rate and other shortcomings, so it cannot b...
