Live piece infinitely variable transmission

Abstract

A movable plate continuously variable transmission, comprising: a driving conical disc set and a passive conical disc set, and an annular transmission belt sleeved on the active conical disc set and the passive conical disc set, wherein the transmission belt comprises: an annular carrier and a transverse member installed on the annular carrier, the transverse members are arranged in continuous arrangement on the annular carrier, and can move laterally left and right on the axis of the annular carrier, so that the two side surfaces of the transmission belt It can form tooth profile of any shape and size. Drive teeth are arranged on the conical surfaces of the conical disks included in the driving conical disk group and the passive conical disk group. The beneficial effects of the present invention are: the continuously variable transmission can realize tooth meshing continuously variable speed transmission, and overcomes the conventional continuously variable transmissions that rely on friction transmission for small transmission torque, low load capacity, poor anti-overload and impact resistance performance, and large slip rate , low mechanical efficiency, large power loss, limited transmission power, and limited application range.

Description

[0001] Technical field [0002] The invention relates to a mechanical transmission device, belonging to the technical field of mechanical transmission, in particular to a continuously variable transmission. Background technique [0003] At present, most CVTs use friction transmission, because of their small transmission torque, low bearing capacity, poor overload and shock resistance, large slip rate, and low mechanical efficiency; some also have pulsating output and discontinuous power flow; transmission; The power needs to increase the larger pressing force on the transmission belt to increase the frictional force, thus causing a larger power loss, and increasing the load of each bearing, and the bearing is easily damaged; the effective contact surface for power transmission is small, theoretically Line contact or point contact has large local stress, which is easy to cause scratches or gluing on the working surface, limited transmission power, and short life, which limits t...

[0003] At present, most continuously variable transmissions use friction transmission, because of their small transmission torque, low load-carrying capacity, poor anti-overload and anti-shock performance, large slip rate, and low mechanical efficiency; some also have pulsating output and discontinuous power flow; transmission The power needs to increase a large pressing force on the transmission belt to increase the friction, thus causing a large power loss, and causing the load of each bearing to increase, and the bearing is easily damaged; the effective contact surface for power transmission is small, theoretically Line contact or point contact, large local stress, easy to cause scratches or glue on the working surface, limited transmission power, short life, which limits the scope of application

The slide chain relies on the groove sprocket and the slide chain to transmit power in a quasi-engagement manner. It has the advantages of low sliding rate, precise transmission, wear resistance, and high impact capacity. However, because the slide of the slide chain is on the slide chain It is a non-continuous arrangement. When the sliders of the slider chain mesh with the grooves on the surface of the grooved sprocket, only one or a few pieces may be stressed, so it is easy to cause the sliders to break and damage
