Design method for oscillating-tooth continuously variable transmission slide sheet

Abstract

The invention discloses a design method for a slide sheet of an oscillating-tooth continuously variable transmission device, belongs to the technical field of design and manufacturing for continuously variable transmission devices, solves the problem of line-surface contact of a traditional continuously variable transmission device during engagement of a slide sheet and chain teeth, and is technical innovation and development on the basis of the traditional continuously variable transmission device. According to the design method disclosed by the invention, a traditional right-angled slide sheet is designed to be a fan-shaped slide sheet, and the two side surfaces of the fan-shaped slide sheet are intersected at the central axis of the arc surface of the outline of an oscillating-tooth unit beam. The line-surface contact during the engagement process of the slide sheet and the chain teeth is changed into surface-surface contact during high-speed running of the oscillating-tooth continuously variable transmission device; on one hand, a transfer torque of the oscillating-tooth continuously variable transmission device is increased, and transfer efficiency is increased; and on the other hand, the problem of stress concentration during the engagement of the slide sheet and the chain teeth is solved, the lives of a metal chain and the slide sheet are prolonged, and transfer stability is improved. The oscillating-tooth continuously variable transmission device can be 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 continuously variable speed transmission device design and manufacture. Background technique [0002] Gear transmission is a widely used transmission mechanism in the mechanical field, but this mechanism has high manufacturing precision and installation precision, and its transmission ratio is fixed, so it cannot realize stepless speed change. With the rapid development of science and technology, continuously variable transmission is widely used in the automobile industry as an ideal transmission. Patent 200580039668.6 (slide deformed teeth stepless meshing movable gear, authorized announcement date: June 10, 2009, authorized announcement number: CN 100498006C) introduces a sliding plate deformed movable teeth stepless meshed movable gear device, movable teeth The continuously variable transmission device is a continuously variable transmission based on the theory of movable tooth meshing. This movable t...

Problems solved by technology

When meshing, the edge line of the sprocket meshing surface will first contact with the sliding plate meshing surface. This kind of line-surface contact will cause the instability of the transmission on the one hand when the movable tooth CVT is running at high speed, reducing the transmission torque and reducing Transmission efficiency; on the other hand, a large stress concentration will be generated at the meshing point, especially for the sliding plate (thin, about 2mm), which may cause fracture, etc., which will pose a great threat to the life of the meshing parts
