Transmission device

Abstract

The invention provides a transmission device. The transmission device comprises multiple belt wheels, a belt connected with the belt wheels, racks, optical shafts, fixed plates and moving plates; theoptical shafts and the fixed plates are fixed to the racks; first wheel sets are fixedly arranged on the racks, second wheel sets are fixedly arranged on the moving plates, one belt wheel in each first wheel set serves an input wheel, one belt wheel in each second wheel set serves as an output wheel, two wheel sets are in series connection through a transmission belt, and the positions of the moving plates in the vertical direction are adjusted through a control handle, the transmission belt part, between the first wheel sets, of the transmission belt is parallel to the transmission belt part,between the first wheel sets and the second wheel sets, of the transmission belt, and the two transmission belt parts of the transmission belt are parallel to the moving direction of the moving plates. When the handle is rotated to enable the moving plates to ascend or descend, the axial distances between the output wheels and the input wheels are changed, the length of the transmission belt cannot be changed, and normal work is not affected.

Description

technical field [0001] The invention relates to the field of mechanical power transmission, in particular to a transmission device. Background technique [0002] Belts (or chains) are often used to transmit power in mechanical equipment. When traditional belts or chains are used to transmit power, the wheelbase of the two shafts is generally required to be a fixed value. If the wheelbase changes, the length of the belt or chain will be insufficient. Or the belt is loose and power transmission cannot be fully realized. Under normal circumstances, changing the wheelbase will cause the belt to break or loosen, so that it cannot work normally. [0003] Occasionally, in mechanical equipment, it is necessary to transmit power when the wheelbase changes. At present, dual motors are often used to drive, or the direction of power is changed by using a worm turbine and then the spline principle is used to make the distance variable. Relatively speaking The cost is relatively high. ...
