Transmission tensioning device

Abstract

The invention discloses a transmission tensioning device. The transmission tensioning device comprises a motor base, a motor casing, an eccentric shaft, a shaft, a sliding block and a fulcrum shaft; one end of the motor base is connected with the motor casing through the fulcrum shaft and rotates around the fulcrum shaft; the other end of the motor base and the shaft are fixed together; the sliding block which sleeves the shaft is fixed at the edge of the shaft end of the eccentric shaft; circular motion is performed on the sliding block along with rotation of the eccentric shaft and the sliding block slides on the shaft simultaneously. According to the transmission tensioning device, the traditional transmission design scheme of tensioning wheels and tensioning belts is cancelled, ahandle needs to be rotated only and the height difference produced by rotation of the eccentric shaft is utilized to raise the motor base and shorten the distance between a motor belt wheel and a belt wheel, so that the installation and replacement of a transmission belt is rapid and convenient; the gravity of a motor is utilized and the structure of the eccentric shaft, a pin shaft and the sliding block is adopted to tension the belt to perform transmission; a gear of the belt on the motor belt wheel can be conveniently adjusted and the operating speed of a machine can be adjusted without any tool.

Description

technical field [0001] The invention relates to a motor transmission device, in particular to a transmission tensioning device. Background technique [0002] At present, in the field of textile machinery design, most of them rely on the main motor to transmit power to each actuator through belt drive. The traditional or similar models of drive belt tensioning methods are all realized by installing a tensioning wheel on one side of the belt. , but for motors that require a high maximum delivery speed, or often need to change the position of the belt on the tower pulley to change the running speed of the whole machine, this tensioning method has the following disadvantages: [0003] 1. It is troublesome and inconvenient to change the running speed of the whole machine or replace the belt; [0004] 2. Vibration will be generated when the motor is running at high speed, which will affect the operation performance of the whole machine; [0005] 3. It is easy to cause half of th...
