[0002] Belt drive, also known as "belt drive", is a type of mechanical transmission. It consists of one or more belts tightly wrapped around two wheels (called "pulleys"). During the operation of the belt, vibration will occur. If the amplitude is too large, it will affect the transmission quality and belt life. Therefore, the performance of the transmission belt is particularly important. At present, the transmission belt mainly includes toothed belts and toothed belts. Therefore, in the actual rubber belt processing and production process, a good transmission performance dynamic test device is particularly important.

In the process, the belt adapter 6 can be driven to move at the same time to achieve the tensioning of the belt. The adjusting mounting plate 501 is set, and the sliding control plate 705 is moved to realize that when the driving shaft 104 rotates, the transmission shaft 701 is driven to rotate at the same time, and the extrusion cam 703 on the sliding mounting cylinder 702 is driven to rotate.

Block 901 rubs against the belt, causing the belt to generate frictional heat. By rotating the scraping lifting screw rod 904, the sliding scraping block 903 can be driven to rise in height, achieving strong scraping and accelerating destructive testing. It can be observed whether the pulley 602 on the rotating mounting shaft 102 is slipping. By rotating the detection advancing threaded rod 202, the external vibration detector 302 can be driven to connect the belt periphery for detection. At the same time, by rotating the detection threaded rod 304, the upper vibration detector 303 can be driven to detect the side vibration parameters of the belt. By rotating the lateral driving threaded rod 205, the lateral position of the detection can be adjusted.

[0031] Finally, it should be noted that when describing the position of each component and the matching relationship between them, the present invention usually takes one / a pair of components as an example. However, those skilled in the art should understand that such position, matching relationship, etc. are also applicable to other components / other pairs of components.

[0032] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
