Advantages and disadvantages of coincidence degree to belt drive

Advantages: improving transmission effect and output power, disadvantages: increasing energy loss and noise.

The coincidence degree will affect the performance and application effect of belt drive. Specifically, the advantages and disadvantages of coincidence degree to belt drive are as follows:

Benefits:

1, when the overlap ratio is large, the pulley transmission efficiency is high, it can bear more load and torque, and the transmission effect and output power are improved.

2. When the coincidence degree is large, the friction between pulleys is large, which can improve the traction and transmission accuracy of transmission.

3. When the coincidence degree is large, the service life of the pulley is relatively long, the maintenance cost is low, and the equipment running for a long time is more economical.

Disadvantages:

1, when the overlap ratio is large, the belt speed of belt drive will slow down, so the transmission efficiency will decrease and the working efficiency of mechanical equipment will be affected. Br>2. When the overlap ratio is large, the friction between pulleys will also increase, thus increasing energy loss and noise, which may cause interference to equipment with high noise sensitivity.

3. When the overlap between pulleys is too large, it will increase the wear and heat of the belt, accelerate the aging and damage of the belt, and cause certain difficulties to the maintenance and repair of the equipment.

Coincidence refers to the ratio of the length of the overlapping part of two pulleys to the belt length in belt drive. The influence of coincidence degree on belt drive is twofold, and it is necessary to determine the appropriate coincidence degree according to the specific use situation and work requirements.
