Now, with the development of industry field, the belt pulley is used more and more extensively. With the popularization of belt pulley application, many people generate various doubts. Now we focus on explaining the reason why the belt pulley wears the belt. In the usage of mechanical equipment, the belt pulley inevitably generates excess temperature in the transmission, then the "wear" of belt may occur. Why does such phenomenon happen? The following several reasons are analyzed for the reference. 

The used belt doesn't match with the model of the used belt pulley. The Type A, the Type SPA and the Type XPA belts are corresponding to the Type SPA belt pulley. The Type B, the Type SPB and the Type XPB belts are corresponding to the Type SPB belt pulley. 

It should be noted that the Type XPA belt and Type A belt distinguish with the Type SPA belt and the belt in the Type beginning with the X is equipped with the tooth, which has better heat dissipation and could adapt high-speed running. 

The second reason is that the belt pulley size doesn't meet the torque of machine, with heavy load. The excessive stress of belt causes the slipping. 

The third reason is that one group of driving belt pulleys is on the same horizontal line, which would influence the transmission of belt pulley. 

The above reasons explain why the belt pulley wears the belt. You could consult us if having questions and needing help.
