Abstract

The invention discloses a speed changing device which comprises a rotating main shaft, a fixed rotating disc fixedly connected to the rotating main shaft and driven rotating discs symmetrically arranged at two sides of the fixed rotating disc, the driven rotating discs are rotatably connected with the rotating main shaft, the fixed rotating disc and the driven rotating disc are provided with strip-shaped chutes matched with each other, the number of the strip-shaped chutes in the fixed rotating disc and the driven rotating disc is multiple, the multiple strip-shaped chutes in the fixed rotating disc are uniformly distributed along the circumference, the multiple strip-shaped chutes in the driven rotating disc are uniformly distributed along the circumference, a sliding rod is arranged in each strip-shaped chute, the extending direction of the sliding rod is perpendicular to the plane where the fixed rotating disc is located, the sliding rod is rotatably connected with a roller matchedwith the strip-shaped chute, and the roller can only slide and roll relative to the strip-shaped chute. According to the device, a new speed changing mode is provided the characteristics of light weight, small size, low manufacturing cost and large transmission ratio change range are achieved, the condition that an engine always does work in a rated power range can be guaranteed, the service lifetime of the engine is prolonged, and the applicability is high.

Description

technical field [0001] The present invention relates to the technical field of speed change transmission, and specifically refers to a speed change device. Background technique [0002] Variable speed transmission is a commonly used form of function transformation.
