Abstract

The invention provides a self-tensionsynchronization wheel shaft single-side fixing device, including firm banking plate, tensioning bolt and bar shaped top board; Square bearing mounting blocks are provided on the upside of firm banking plate; Chute is equipped on the left and right side of square bearing mounting blocks; Cylinder-shaped bearing mounting blocks are provided on the downside of firm banking plate; The axle hole for sequentially passing through square bearing mounting blocks, firm banking plate and cylinder-shaped bearing mounting blocks from top to bottom is provided in the center of square bearing mounting blocks; Back-up ring is fixed in axle hole; Screwed hole is provided with the leading flank of square bearing mounting blocks; The screw rod of tensioning bolt is screwed on threaded hole through the bar-shaped top board. In the single-side fixing device, the supporting wheel, the wheel support, the upper structural plate and the bearing seat on the upper structural plate are omitted from the other side of the synchronizing wheel shaft, so that the volume, the complexity and the weight of the transmission system are greatly reduced, and the tightening degree of the synchronous belt is convenient to control, and the tool can be removed after use.

Description

technical field [0001] The invention relates to a synchronous wheel shaft fixing device, in particular to a synchronous wheel shaft one-side fixing device. Background technique [0002] The synchronous wheel drive is composed of an endless belt with equally spaced teeth on the inner peripheral surface and a pulley with corresponding teeth. During operation, the belt teeth mesh with the tooth grooves of the pulley to transmit motion and power. It is a comprehensive belt Transmission, chain transmission and gear transmission have their own advantages, such as accurate transmission ratio, no slip, stable transmission, low noise, high transmission efficiency, and large speed ratio range. Therefore, the synchronous wheel drive is also widely used in unmanned helicopters. [0003] The synchronous belt needs to be given a certain tension in order to transmit power stably. There are two main ways of tensioning the synchronous belt: one is to use the tensioning wheel to press the s...
