Problems solved by technology
[0002] During the working process of the belt tensioning wheel, the moving body of the support plate is still and a large friction is formed between them, so a damping member is arranged between the support plate and the body, thereby improving the service life of the entire tensioning wheel, but the existing technology Washers are usually used to pad between the support plate and the body. In the actual work process, the rotation will occur without the washer, which will make the entire tensioning wheel loose and cause abnormal noise, and the formed gap will increase the entry of dust and foreign objects. degree, leading to a reduction in the life of the tensioner

Embodiment Construction
[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0025] Such as figure 1 , 2 As shown in and 3, a dust-proof anti-rotation belt tensioner includes a body 1, a support plate 2, and a damper 3 connecting the body 1 and the support plate 2, and the damper 3 includes a wear-reducing plate 31 and a connection On the extension 32 of the outer ring of the wear reduction plate 31, the thickness of the extension 32 is greater than the thickness of the wear reduction plate 31, and the wear reduction plate 31 protects the support plate 2 and the body 1 Function, the existence of the extension edge 32 can increase the contact area between the damping member 3 and the body 1 and the support plate 2, can effectively reduce the pressure on the damping member 3, and improve the service life. The wear-reducing plate 31 is at least provided with a limiting opening 4 and a limiting convex point 5, the support plate 2 is pro...

The invention designs a dustproof anti-rotation belt tensioner for solving the problems that a belt tensioner is short in service life and a gasket is inconvenient to use. The dustproof anti-rotationbelt tensioner comprises a body, a supporting plate and a damping part connecting the body with the supporting plate; the damping part comprises an antifriction plate and an extension side connected to the outer ring of the antifriction plate; the thickness of the extension side is larger than that of the antifriction plate; the damping part of the dual-way edge turning structure is added betweenthe supporting plate and the main body, dust and foreign matter can effectively prevent from entering, the contact area of the damping part is increased, pressure borne by the damping part is effectively reduced, the service life of the damping part is prolonged, a limiting protrusion point of the damping part is in assembled connection with a limiting concave pit on the body, and through limitingof a limiting block and a limiting groove, rotation of the damping part can be effectively prevented.
Description
technical field [0001] The invention relates to the technical field of pulley system design, in particular to a dust-proof and anti-rotation belt tensioner. Background technique [0002] During the working process of the belt tensioning wheel, the moving body of the support plate is still and a large friction is formed between them, so a damping member is arranged between the support plate and the body, thereby improving the service life of the entire tensioning wheel, but the existing technology Washers are usually used to pad between the support plate and the body. In the actual work process, the rotation will occur without the washer, which will make the entire tensioning wheel loose and cause abnormal noise, and the formed gap will increase the entry of dust and foreign objects. To a certain extent, the life of the tensioner is reduced. Contents of the invention [0003] In order to solve the above technical problems, the present invention designs a dust-proof and ant...
