Principle of planetary gear reducer


A planetary gear reducer is commonly used in low-speed, high-torque applications. It works by taking high-speed input from a motor, internal combustion engine, or other power source and transmitting it through the gears on the input shaft. These gears then engage with larger gears on the output shaft, which reduces the speed while increasing the torque. This mechanism is essential for many industrial and mechanical systems where controlled, powerful movement is required. Most planetary reducers use multiple sets of gears that follow the same principle to achieve the desired reduction ratio. The transmission ratio is determined by the number of teeth on the large and small gears. For example, if the driving gear has 20 teeth and the driven gear has 100 teeth, the ratio would be 5:1, meaning the output speed is reduced five times while the torque is increased accordingly. Planetary gear systems are known for their compact design, efficiency, and ability to handle heavy loads. They are widely used in robotics, automotive transmissions, wind turbines, and various types of machinery. Their versatility makes them an important component in modern engineering solutions.
