Why is the mechanical transmission system in the belt drive on the high-speed level and the chain drive at low speed?
Because the high-speed impact load is relatively large, belt drive shock absorption, reduce the impact of the role of the impact, while the belt slip and overload protection role. Belt drive is a protective ring. Chain drive can not reduce the vibration inertia, can only be used in low-speed transmission occasions.
Chain drive is not suitable for high-speed, especially the relatively heavy chain, inertia is too large, can only be used in low-speed transmission occasions. Belt drive can be used in high-speed transmission. [Belt drive there is vibration, noise.
Because of the characteristics of the two drives (high speed and high speed, low speed and low speed and large transmission power), the mechanical transmission system determines the belt drive on the high-speed level and the chain drive at low speed.
The belt drive is characterized by the fact that the transmission force is driven by the friction force of the pulley and the belt, and the strength of the belt is limited. Therefore, the transmission force is small, but its structure is simple and can be used for the movement of the long distance. , This transmission to reduce the high-speed movement of the impact of vibration, smooth operation, low noise. Therefore, the transmission speed is high (5-25m / s).
