What is the relationship between the elastic slip of belt drive and the effective tension at the initial tension of the belt?
If the work load is increased further, the effective circle reaches the critical value Fec, then the belt and pulley will slide relatively significant, which is slipping. Slip will aggravate the wear of the belt, and the speed of the driven wheel will decrease sharply and the belt drive will fail. This situation should be avoided.2. the relationship between the initial tension and the effective working tension
The belt drive has not been working, with the preload of transmission is F0, remember belt and small pulley or pulley between the total frictional force is Ff, the value of which is decided by the power P belt and V belt speed.The effective pulling force of the belt determined by the load is Fe = P/v, and there is obviously Fe = Ff. The Euler formula gives the relation between the forces of the belt drive in the limit state, or the maximum effective pull Fec that a belt drive can provide.
Elastic slide: belt drive at work, from the tight side to the loose side, the belt is subject to changes in tension, so the band of elastic deformation is also changing. In belt transmission, the relative motion between the belt and the pulley due to the elastic deformation of the belt is called elastic sliding. The elastic sliding results in the circumferential velocity V2 of the driven wheel, the circumference speed V1 of the driving wheel, and the degree of velocity reduction can be expressed by sliding rate epsilon.
