Embodiment Construction

[0017] Examples of the present invention figure 1 , figure 2 , image 3 Shown.

[0018] The present invention is innovatively improved on the basis of the metal belt or metal chain continuously variable transmission. The conical surface of the bevel wheel is designed as a pyramid surface to increase the friction between the metal belt or chain and the bevel wheel, such as figure 1 Shown. The pyramid surface can increase the friction between the metal belt or chain and the bevel wheel through the equidistant ridge line, thereby reducing the slipping phenomenon in the transmission process, and can increase the torque of the continuously variable transmission, and improve its power transmission capacity .

[0019] The edge angle of the two adjacent planes of the pyramid surface is 175 0 -178 0 , The cone angle between two adjacent edges is 22.5 0 . The cone angle determines the number of planes that make up the pyramid surface. The number of planes should not be too much. Too much ...

Abstract

The invention discloses a design method for a continuously variable transmission device, and belongs to the technical field of design and manufacturing for continuously variable transmission devices. The invention discloses a design method for a novel continuously variable transmission device on the basis of the traditional metal belt-type or metal chain-type continuously variable transmissions and oscillating tooth continuously variable transmissions. According to the design method, a friction force between a metal belt or chain and the traditional conical wheel is increased by designing the conical surface of the conical wheel to be a pyramidal surface, and a slipping phenomenon during a transmission process is reduced and the torque of continuously variable transmission is increased by increasing the friction force; and the design method can be applied to the traditional metal belt-type or chain-type continuously variable transmission devices and oscillating tooth continuously variable transmission devices. The designed continuously variable transmission device is capable of bearing a high torque, high in transmission efficiency, simple in structure, and capable of being widely applied to the fields of high-speed and high-power vehicles, and industry.

Description

Technical field [0001] The invention belongs to the technical field of design and manufacture of a continuously variable transmission device. Background technique [0002] In the mechanical field, gear transmission is a very widely used transmission mechanism, but this kind of mechanism has high manufacturing precision and installation precision, and its transmission ratio is fixed, which cannot realize continuously variable transmission. With the rapid development of science and technology, continuously variable transmission as a more ideal transmission has been widely used in the automotive industry. At present, the continuously variable transmission for vehicles is mainly metal belt type continuously variable transmission and metal chain type continuously variable transmission, which adopts friction transmission The way, that is, the conical wheel of the conical surface transmits power by axially clamping the metal belt or chain. However, the torque transmitted by this fricti...
