Abstract

The invention discloses a micro-amplitude low-frequency tensioning device for flexible transmission. The micro-amplitude low-frequency tensioning device comprises a machine frame, a planetary gear mechanism, a crank rocker mechanism and a tensioning execution mechanism. A driven wheel axle is of a hollow structure, one end of the driven wheel axle is fixedly connected with a driven wheel through a flange and a bolt, and the other end of the driven wheel axle is supported on the machine frame and can rotate. The planetary gear mechanism is arranged in a cylindrical space of the hollow driven wheel, a tooth ring is arranged on the circumference of the inner side of the driven wheel, a planetary gear is meshed with a center gear and the tooth ring, and the center gear is fixedly connected to the machine frame. A planet frame is provided with a crank pin; the crank rocker mechanism is formed through the hinging of the crank pin, a connecting rod, a rocker bar and the machine frame, and the bar length ratio is set so that the rocker bar performs small oscillating angle movement. A pressing wheel is installed on a guide rod fixedly connected with the rocker bar. The device does not rely on the gravity principle; and when the machine frame performs complex spatial movement or a frequently-used tensioning mode fails in the slight gravity and even weightless environment, the device stills has a tensioning and vibration absorption function.

Description

technical field [0001] The present invention relates to an automatic tensioning device used in occasions where the commonly used tensioning methods in friction-type or meshing-type flexible transmissions are ineffective or even ineffective, and in particular to a micro-amplitude low-frequency tensioning device for flexible transmissions . Background technique [0002] Flexible transmission is very common in mechanical transmission, and can be composed of two or more transmission wheels and an intermediate annular flexible member. When the driving wheel moves, the motion and torque are transmitted to each transmission wheel through the flexible member. Common flexible transmissions mainly include belt transmission, chain transmission and rope transmission with pulleys, sprockets and rope wheels as transmission wheels, and the flexible parts are transmission belts, transmission chains and transmission ropes respectively; from the perspective of transmission principle , there ...
