Hycote Workshop Belt Slip, 400 ml
- Brand: Unbranded
Description
The higher the circumferential forces to be transmitted and the more elastic the belt is, the higher the elastic slip! S = \frac{\epsilon_t-\epsilon_s}{1+\epsilon_t} = \frac{\frac{F_t}{E \cdot A}-\frac{F_s}{E\cdot A}}{1+\frac{F_t}{E\cdot A}} = \frac{F_t-F_s}{E \cdot A+F_t}\\[5px] sounds to me like the belt has stretched slightly and dried on the long journey. My timing belt, fan belt and air-con belt was changed last may, however, since then, i havent done a long journey like this with my air-con switched on, on the motorway.

The reduction in peripheral speed between the driving pulley and the driven pulley is directly relatet to a loss in power, because a decrease of the circumferential speed v at a transmitting circumferential force F c means a direct decrease in power according to the P=F c⋅v. i took it from london to manchester yesterday, around a 200mile drive, and found that when i got there, i started to get a squealing-screeching noise when i accelerate on first and second gear. Since the circumferential speeds can also be expressed by the rotational speeds n and pulley diameters d (v=π⋅d⋅n), the elastic slip can also be determined as follows: The relative motion on the pulleys, which is always present due to the elasticity of the belt, is called elastic slip (partial relative motion between belt and pulley)!The belt adapts to the different speeds by elastic slip on the pulleys! Circumferential speed of the pulleys The higher the circumferential forces to be transmitted and the more elastic the belt is (e.g. low Young’s modulus!), the greater the elastic slip. With the increased elastic slip, the sliding zone also includes a larger portion of the wrap angle. Figure: Increase in elastic slip with increase in circumferential force With the definition of the elastic slip S as the ratio of speed loss Δv and circumferential speed of the input pulley v i, the following formula applies v o: circumferential speed of the output pulley):

The entire wrap area φ can therefore be divided into two zones. In the co-called sliding zoneφ’ a relative motion takes place between belt and pulley. With the acting sliding friction, this zone ensures the transmission of the circumferential force. In the remaining adhesion zone, the belt adheres to the pulley without a relative motion and without force transmission. Note that in this case it is not, as previously always assumed, the static limit case in which the belt is not yet slipping. Rather, slipping is already present from the very beginning due to the elastic slip (µ s as coefficient of sliding friction!). Sliding slip is the complete sliding of the belt over the entire pulley in the event of overload (complete relative motion between belt and pulley)! Belt speedsNote: In the previous articles on belt drives, the sliding anglewas equated with the wrap anglefor reasons of conservative calculations. The statements made must then always be interpreted at the limit to sliding slip! Calculation of the elastic slip

As can be seen from the animation below, the belt is running more and more ahead due to the increasing stretching on the driven pulley. This means that the speed of an imaginary point on the belt is always slightly higher than the peripheral speed of the pulley. This corresponds to the relative motion between belt and pulley described above. The figure below shows schematically the distribution of the speed along the belt according to the animation above. Figure: Speed distribution along the belt In addition to elastic slip, which is due to the elasticity of the belt, the belt can also slip completely over the entire driven pulley in the event of overload. This is then referred to as sliding slip.Note that every belt has a certain elasticity and therefore always results in elastic slip, whereby sliding slip should always be avoided.
