What is the difference between the elastic slip and the slip phenomenon of belt drives?
The results of elastic sliding are as follows: 1) the transmission ratio is not stable; 2) reduce the transmission efficiency; 3) cause the wear of belt and the temperature rise of belt, and reduce the life of beltThe elastic sliding zone is due to the tension difference and the elastic deformation caused by the elastic deformation and the elastic modulus of the belt, the high elastic modulus with material, can reduce the elastic slip, but because of friction tape drive, it is through the elastic belt tension load transmission, so the elastic slip is the inherent characteristics of belt transmission work, can not completely eliminate is inevitable.
This shows that with bypass pulley in belt shrinks backwards relative to the wheel surface (1 - 8 2), and the local relative sliding pulley surface between the lead belt, belt speed is less than the circumference of the driving wheel speed gradually. Similarly, in a driven wheel, when the belt from point C to point d the movement process, the tension increases gradually, gradually elongated along the wheel surface relative sliding forward, the belt speed is more than V between the belt and the belt wheel sliding is called elastic sliding zone from the circumferential velocity v 2. wheel due to the elastic deformation produced.
Elastic slip of bandThe drive belt is an elastic body, the tension will produce elastic deformation due to the tight side and slack side tension, the elastic deformation is also different. As shown in Figure 7-12, when the edge points in the a around the driving wheel, the pulling force of the F 1, with the line speed of V and the circumference of the driving wheel the speed of v 1 phase. In the driving wheel and the belt from a to B during the movement, with the tension reduced by F 1 to F 2, the elastic elongation decreases as the delta delta 1 by 2
