A movable tooth continuously variable transmission device

Abstract

The invention discloses a movable tooth stepless speed change transmission device, belongs to the design and manufacturing technical field of stepless speed change transmission devices, has and widens the functions and the technologies of movable tooth stepless speed changers, can bear high torque, and is high in transmission efficiency and simple in structure. The invention can solve the slip problem between a metal tooth-shaped chain and a driven wheel in the starting phase of a traditional movable tooth stepless speed changer. The invention proposes a novel movable tooth stepless speed change transmission device, that is, movable tooth bevel gears at the same sides of a driving wheel and a driven wheel are designed as bevel gears having engaged teeth at the edges; a transition gear is mounted between the bevel gears at the same sides; and the movable tooth bevel gear at the other side is not changed. As a traditional movable tooth stepless speed change bevel gear machine is simply improved and designed, the slip problem of the chain and the driven wheel in the starting process can be radically solved. The novel movable tooth stepless speed change transmission device can be widely applied to the industrial field of high-speed and high-power vehicles.

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...
