Description

Technical Field

[0001] The utility model relates to the field of tensioning mechanisms, in particular to a spring tensioning mechanism. Background Art

[0002] The spring tensioner is a commonly used retaining device in belt and chain drive systems. In order to keep the timing belt and timing chain at the appropriate tension, that is, to prevent them from jumping due to being too loose and being damaged due to being too tight, there is a special tensioning system. The spring tensioner provides pressure directed to the belt or chain. The tensioner is in direct contact with the timing belt, and the guide rail is in direct contact with the timing chain. As the belt or chain runs, they apply the pressure provided by the spring tensioner to it, so that they maintain the appropriate tension.

[0003] However, it still has some disadvantages. For example, after the spring tensioning mechanism is installed in the specified position, the pressure on the belt and chain is applied by manual adjustment of the spring tensioning mechanism to adjust the tension. The existing spring tensioning mechanism adjustment method is not simple enough, and the height of the spring tensioning mechanism cannot be controlled during pre-installation.
