The V-belt transmission is a common power transmission device with low cost, and has the characteristics of simple structure, low manufacturing cost, high transmission efficiency, low working noise, stable movement, convenience in installation and maintenance and the like, so that a plurality of machines use belt transmission as the power transmission device. Because the belt used for V-belt transmission has certain elasticity, after the V-belt transmission is used for a period of time, the V-belt can be loosened due to plastic deformation, the friction force between the V-belt and the wheel surface of the belt wheel is reduced, the phenomenon of belt slipping is generated, and the normal transmission work of the V-belt is further influenced. From the above analysis, it can be known that after the V-belt and the pulley are used for a period of time, the V-belt needs to be tensioned so that the V-belt always maintains a proper tension and the belt is prevented from slipping.

In the prior art, V belt tensioning is generally realized by adjusting center distance and adopting a tensioning wheel. Traditional adjustment centre-to-centre spacing is through removing the centre-to-centre spacing from driving wheel and action wheel, make the belt tensioning from between driving wheel and the action wheel, but when adjusting the position from the driving wheel, because the tensioning is difficult to master from the driving wheel regulating variable, if adjust improperly, make from the driving wheel too big apart from the distance of action wheel, will make the belt tension lead to the fracture, if make from the distance of driving wheel and action wheel on the small side, will make the belt too loose and the phenomenon that skids appears, so need carry out many times the debugging repeatedly and just can adjust suitable position from the driving wheel, the process of regulation is comparatively loaded down with trivial details, operator working strength is great, and work efficiency is extremely low. The tension wheel is adopted for tensioning a follow-up wheel pressed on a belt for changing the wrap angle of a belt pulley or controlling the tension force of the belt, the tension wheel is usually added between the drive wheel and the follow-up wheel, and the position of the tension wheel can be determined only by repeatedly debugging for many times.
