[0014] Through the above technical scheme, polyethylene foam plastic has the characteristics of small density, good flexibility, high recovery rate, strong impact resistance and the like. During the operation of the belt wheel, when impacted or vibrated, the material can effectively absorb and disperse energy, buffers the impact force through deformation of itself, reduces damage to the belt wheel and other components, and improves the service life of the belt wheel and the related transmission system.

[0018] Compared with the prior art, the utility model has the beneficial effects that:

[0019] The reasonable installation of the main buffer assembly and the auxiliary buffer assembly in the belt wheel ensures that when the belt wheel is impacted from outside or vibrated during operation, the buffer pad can absorb energy through elastic deformation of itself, reduces the influence of impact and vibration on the belt wheel and the entire transmission system, and for example, in some devices with intermittent load, the buffer assembly can prevent sudden load change from damaging the belt wheel.

[0020] The utility model discloses a buffering assembly is installed firmly in the installation groove of pulley, improves the reliability of whole pulley structure, buffering assembly can play a role continuously in the long -term working process, protects pulley and other related parts, reduces the frequency of maintenance and replacement, reduces the maintenance cost of equipment, and through the fastening effect of fixed bolt, can prevent the displacement of second buffer pad in the pulley working process because of vibration, centrifugal force and other factors, ensure that second buffer pad is always in correct working position, thereby guaranteeing the effective play of its buffering function.
