1. What is a sprocket?

A sprocket is a gear-like component used to transmit power through a chain.
It’s commonly found in motorcycles, bicycles, industrial machinery, and conveyor systems, efficiently transferring engine or motor power to wheels or devices.

2. Main functions

• Transmits power via the chain
• Adjusts torque and speed
• Ensures smooth and stable movement

3. Types of sprockets

• Drive sprocket (front): Receives power from the engine or motor
• Driven sprocket (rear): Transfers power to wheels or devices
• Double/Triple sprockets: Used in machines requiring multi-stage power transmission

4. Common materials

• Steel: Durable and cost-effective
• Aluminum: Lightweight, ideal for sports use
• Stainless steel: Corrosion-resistant and suitable for harsh environments

5. How to choose the right sprocket

• Select the material and tooth count based on intended use
• Changing the tooth count can adjust acceleration and top speed
• Regular inspection and replacement ensure smooth operation

6. Conclusion

The sprocket is a key component in power transmission, directly influencing performance and efficiency.
Choosing the right sprocket for your motorcycle or machine will enhance both safety and ride quality.
