Embodiment Construction

[0019] exist figure 1 The front contact surface (2) of the middle chain pin (4) meshes with the peak (10) of the left cone (3), and the peak (10) radially pushes the front contact surface (2) of the chain pin (4) to rotate, and the other end of the chain pin (4) The contact between the rear contact surface (8) and the peak (10) is an axial jacking force, that is, there is no radial thrust nor radial pull. Only one side of the helical bevel teeth at the two ends of the chain pin (4) is radial thrust, and the other side does not have radial thrust and pulling force, and only the axial jacking force is follow-up. refer to Figure 5 Each chain pin (4) has four contact surfaces of bevel teeth at both ends. When two front contact surfaces (2) and two rear contact surfaces (8) are in contact with the left and right cones, there is only one front contact surface (2) and one The rear contact surface (8) is in contact with the peak and valley teeth of the left and right cones, and no ...

Abstract

A universal toothed chain type stepless speed change transmission device is mainly composed of a left cone disc, a right cone disc and a transmission disc. The universal toothed chain type stepless speed change transmission device is technically characterized in that according to an existing toothed chain type stepless speed changer, radial concave teeth and radial convex teeth on a left cone disc and a right cone disc of a driving wheel and a driven wheel are changed into radial peak valley-shaped teeth; a chain pin is changed to move inside a chain pin sleeve in the axial direction; the two ends of the chain pin are designed to be two-faced inclined conical teeth in the front-back direction; during transmission, the inclined conical teeth at one end are subjected to axial thrust between the peak valley-shaped teeth of the left cone disc or the right cone disc, and the chain pin moves in the axial direction, so that the two-faced inclined conical teeth at the other end of the chain pin are inserted into the valley-shaped portions of the opposite conical disc, and a peak-insertion valley-pin mode is formed. According to the universal toothed chain type stepless speed change transmission device, pure-inclined teeth mesh transmission is achieved, the noise is low, pulsation and slipping are avoided, and the speed ratio torque is quite large.

Description

Technical field [0001] The invention relates to a gear chain type continuously variable transmission device, in particular to a gear chain gearless transmission device with universal tooth chain meshing, no slipping, no pulsation, and very large speed ratio torque. Background technique [0002] At present, known CVT and pendulum pin chain all are friction type continuously variable transmissions, are easy to slip and cannot adapt to high torque. There are several radial concave and convex teeth on the left and right cones of the tooth chain type continuously variable transmission, which are meshed with the sliding plates on both sides of the chain. Friction transmission, the formation of friction and meshing can not be accurately in place, resulting in low speed and small speed ratio torque, it is only used in low speed, small torque machinery and equipment, and all kinds of large, medium and small car transmissions do not use gears Chain continuously variable speed. Cont...
