Topic: Gear Reducer

1. What is a Gear Reducer?
A gear reducer is a mechanical device used to reduce speed and increase torque. It is often installed between a motor and a mechanical load to enhance stability and power transmission.

2. Why Use a Gear Reducer?

• Reduces speed and increases torque

• Improves control accuracy

• Extends equipment life

• Reduces motor load

3. Gear Ratio Formula (Plain Text):
Gear Ratio = Input Speed ÷ Output Speed
Gear Ratio = Output Torque ÷ Input Torque

Example:
If input is 10 kgf and desired output is 150 kgf:
Gear Ratio = 150 ÷ 10 = 15

4. Common Types of Gear Reducers:

• Planetary Gearbox: High precision, compact size

• Spur/Helical Gearbox: High efficiency, durable

• Integrated Gear Motor: Easy installation

• Worm Gearbox: Self-locking, ideal for lifting systems

5. Selection Criteria:
Output torque, installation space, efficiency, lifespan, and cost
