1.Different structure
Gear is an involute tooth shape. The transmission is realized by meshing the teeth of two gears.
Sprocket is a "three arc and one straight line" tooth shape, which is driven by the chain.
2.Different functions
Gear can realize transmission between any staggered shafts.
Sprocket is a kind of gear, which can only realize transmission between parallel shafts;
3.Different precision and price
Gear is high machining accuracy and cost;
Sprocket is low precision and cost.
4. Different Torque
The torque of sprocket is less than gear.
5. Different transmission carrying capacity
The load carrying capacity of sprocket is greater, and the tooth surface wear is less;
6. Different transmission performance
The transmission performance of gears is better when the transmission capacity is limited by space and the center distance is small.
