Movable piece continuously variable transmission

Abstract

A movable piece continuously variable transmission comprises an active cone disk assembly, a passive cone disk assembly and an annular transmission belt arranged on the active cone disk assembly and the passive cone disk assembly in a sleeving manner, and is characterized in that the transmission belt comprises an annular bearing body and transverse parts installed on the annular bearing body; andthe transverse parts are continuously arranged and installed on the annular bearing body, and can transversely move left and right on the axis of the annular bearing body, so that the surfaces of thetwo sides of the transmission belt can form a tooth profile in any shape and size. Transmission teeth are arranged on the cone face of a cone disk included by the active cone disk assembly and the passive cone disk assembly. The movable piece continuously variable transmission has the beneficial effects that the continuously variable transmission can achieve tooth engagement continuously variablespeed transmission, and the defects that a continuously variable transmission performing transmission by means of conventional friction force is small in transmitted torque, low in bearing capacity,poor in overload resistant and impacting resistant performance, large in sliding rate, low in mechanical efficiency, large in power loss, and limited in transmission power and application range are overcome.

Description

Technical field [0001] The invention relates to a mechanical transmission device, which belongs to the technical field of mechanical transmission, in particular to a continuously variable transmission. Background technique [0002] 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, local stress is large, which can easily lead to scratches or glue on the working surface, limited transmiss...

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
