Problems solved by technology

[0003] The structure of the tensioner is various, which generally includes a fixed structure and an elastic automatic adjustment structure. Automatic rebound controls the tension of the belt and chain. At present, the chain tensioner that can be automatically adjusted in China mostly uses a spring structure, but the spring-type tensioning mechanism has the following problems. First, it is difficult to adjust the coplanarity with the sprocket Second, the end surface of the sprocket has a serious beating, and third, the support rigidity of the sprocket is poor; therefore, a chain tensioning mechanism is urgently needed to solve the above problems

Abstract

The invention relates to a chain tensioning mechanism. The chain tensioning mechanism comprises a U-shaped plate fixed to a side plate, a long-strip-shaped hole is formed in the closed end of the U-shaped plate, a square neck screw is in an L shape, the A end of the square neck screw penetrates through an opening of the U-shaped plate and stretches out of the long-strip-shaped hole in the closed end of the U-shaped plate, and the B end of the square neck screw stretches out of a space formed by two perpendicular parts of the U-shaped plate; and an adjusting device used for adjusting the end face position of a tensioning wheel is installed at the end A of the square neck screw, the end face of the tensioning wheel and the end face of a chain wheel are located on a same plane, and a pressure adjusting device used for adjusting the tensioning force of the tensioning wheel is installed at the end B of the square neck screw. The problems generated in the background technology are solved, and the service life of a chain is prolonged.

Description

technical field [0001] The invention relates to a chain tensioning mechanism, which belongs to the field of tensioners. Background technique [0002] The tensioner is a commonly used holding device on the belt and chain transmission system. Its characteristic is to keep the belt and chain with proper tension during the transmission process, so as to avoid the belt slipping, or to prevent the synchronous belt from skipping teeth or detaching the teeth. drag out. Or prevent the chain from loosening and falling off, and reduce the wear and tear of sprockets and chains. [0003] The structure of the tensioner is various, which generally includes a fixed structure and an elastic automatic adjustment structure. Automatic rebound controls the tension of the belt and chain. At present, the chain tensioner that can be automatically adjusted in China mostly uses a spring structure, but the spring-type tensioning mechanism has the following problems. First, it is difficult to adjust ...
