As shown in fig. 1, in a common belt transmission mechanism, a driving wheel 1 and a driven wheel 2 are in transmission connection through a belt 3, and the belt 3 and the driving wheel 1 and the driven wheel 2 are in tight fit to a certain degree, so that the belt 3 and the driving wheel 1 and the driven wheel 2 can be synchronously rotated through friction force, and then the rotation driving force of the driving wheel 1 can be transmitted to the driven wheel 2. The driving wheel 1 and the driven wheel 2 are both belt pulleys.

When the belt transmission mechanism is applied to an engine system, the driving wheel 1 can be mounted on a crankshaft of an engine, and the driven wheel 2 can be mounted on a rotating shaft of a load, so that the rotary driving force of the engine can be transmitted to the load under the action of the belt 3. It will be appreciated that the application scenario of the belt drive is not limited to an engine system, but may be applied to virtually any other type of power system.

As a core technical point of belt transmission, it requires a tight fit between the belt 3 and the pulley, so that the belt 3 and the pulley can have enough friction force to avoid the slip of the belt 3. However, this technique requires that the installation of the belt 3 becomes difficult for a belt drive mechanism without a tension train (i.e., the belt drive mechanism shown in fig. 1).

Therefore, in the prior art, a solution for installing the belt 3 into the pulley by using a screwdriver or the like is available, which, although not requiring too many tools, is liable to damage the belt 3 and the pulley, and may affect the service life of the belt transmission mechanism and the stability of the belt transmission mechanism in the subsequent working process.
