If the tension of the triangular belt of the barite ore mill is too large, the additional bending moment of the shaft and the synthetic moment will be increased.

The stress in the working process of the belt will increase significantly, even exceed the allowable stress of the shaft, which will directly lead to the destruction of the shaft. Therefore, the tension of V-belt needs to be adjusted in time.

It is suggested that the tension of V-belt should be reduced as much as possible on the premise of ensuring normal transmission. Of course, this phenomenon can be avoided by changing to flexible connection.
