### Slippage of the belt in belt drives

0
The relative motion on the pulleys, which is always present due to the elasticity of the belt, is called elastic slip! Elastic slip When the belt rotates around the pulleys, it is exposed...

### Power transmission of a belt drive

0
In this article, learn more about the power transmission in belt drives and the necessary pretensioning force. Circumferential force in the belt In belt drives, forces are transmitted from the input pulley to...

### Centrifugal forces in the belt of a belt drive

0
At high speeds, the centrifugal forces acting on the belt reduce the contact pressure and thus the maximum transmittable circumferential force. Formation of centrifugal forces With a belt drive in a resting state,...

### Maximum belt stress in belt drives

0
In this article, learn more about the maximum belt stress, which must not be exceeded, otherwise the belt will be damaged. Introduction In general, the forces acting in the belt must not exceed...

### Basics of power transmission in belt drives

0
The basis of power transmission in the belt drive is the belt friction equation according to Euler and Eytelwein (rope friction equation). Forces acting on a fixed pulley In the article How does...
