Industrial Sprocket uses a chain drive, and the model unit is usually English. Compared with the gear, it can be used in the situation where the center of the two axes is far away.
The gears are driven by meshing with each other. Most of the model units are metric and expressed by modulus. The chain and sprocket drive has a wide range of power and speed. The compact structure can realize large transmission ratio, high efficiency and long service life.
The difference between sprocket and gear is mainly:
1. The gear is an involute tooth profile, while the sprocket is a "three arc straight line" tooth profile.
2. The gear can realize the transmission between parallel shafts and any staggered shafts, while the sprocket can only realize the transmission between parallel shafts.
3. The gear transmission is compact, while the sprocket can achieve long-distance transmission.
4. The gears are driven by the meshing of the teeth of the two gears, and the chain is driven by the chain between the two sprockets.
6. The gear transmits more torque than the sprocket.
7. Gear machining accuracy and installation cost are higher than sprocket.
8. Sprocket transmission is suitable for transmission with large center distance, and it has the characteristics of light weight and low cost.
9. The processing and installation accuracy of chain and sprocket in the sprocket transmission and the accuracy of the center distance are lower than the requirements of the gear, and its installation and maintenance are also simpler and more convenient.
10. Under normal circumstances, a sprocket has sprocket teeth and a chain participating in meshing at the same time, and the sprocket cogging arc is large, and the stress concentration of the gear is small. Therefore, the sprocket has a higher bearing capacity and the gear surface wear is relatively light.
11. Because the chain has better elasticity, and each hinge part of the chain can store lubricant, compared with rigid contact gear teeth, the sprocket's buffering capacity and vibration absorption capacity are better.
