A transmission tensioning device

Abstract

The invention discloses a transmission tensioning device, which comprises a motor base, a motor box, an eccentric shaft, a shaft, a slider and a support shaft, one end of the motor base is connected with the motor box through the support shaft, and Rotate around the fulcrum, the other end of the motor base is fixed to the shaft, the shaft is covered with a slider, the slider is fixed on the edge of the shaft end of the eccentric shaft and moves in a circle with the rotation of the eccentric shaft , sliding on the shaft at the same time; the present invention cancels the transmission design scheme of the traditional tensioning pulley tensioning belt, only needs to turn the handle, and utilizes the height difference generated by the eccentric shaft to raise the motor base and shorten the motor belt. The distance between the pulley and the pulley makes the installation and replacement of the transmission belt faster and more convenient, and then uses the gravity of the motor to tension the belt for transmission with the structure of eccentric shaft, pin shaft and slider; without using any tools Under certain circumstances, it is convenient to adjust the gear position of the belt on the motor pulley and adjust the running speed of the machine.

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...
