Gears can realize transmission between parallel shafts and any staggered shafts, while sprockets can only realize transmission between parallel shafts.
1. The gear is an involute tooth shape, and the sprocket is a "three arcs and one line" tooth shape.
2. Gears can realize transmission between parallel shafts and any staggered shafts, while sprockets can only realize transmission between parallel shafts.
3. The gear transmission is compact, and the sprocket can realize long-distance transmission.
4. The gear is driven by the meshing of the teeth of the two gears, and the transmission between the two sprockets is achieved by a chain.
5. The torque transmitted by the gear ratio is larger than that of the sprocket.
6. The machining accuracy and installation cost of gears are higher than those of sprockets.
7. Chain drive is suitable for transmission with large middle distance, and has the characteristics of light weight and low cost;
8. The machining accuracy and installation accuracy of the chain and sprocket in the chain drive and the accuracy of the intermediate spacing are lower than the requirements of the gears, and it is easier to install and maintain the existing chain transmission by changing its parameters (transmission ratio, intermediate spacing, etc.). easy and convenient;
9. Under normal circumstances, the chain drive has the characteristics of high sprocket teeth meshing with the chain at the same time, the sprocket tooth slot arc is large, and the gear stress concentration is small. Therefore, the chain drive has a large bearing capacity, and the wheel The tooth appearance wear is also relatively light;
10. Because the chain has good elasticity, and each hinge part of the chain can store lubricating oil, therefore, compared with the rigid contact gear teeth, it has better buffering ability and vibration-absorbing ability.
