The difference between planetary and turbo reducers

Worm gear reducers and planetary reducers are two commonly used deceleration devices that have the function of reducing output speed and increasing torque (load capacity). The gearbox structure, transmission parameters, specifications, and applicability of worm gear reducers and planetary reducers are different. Below, the editor will briefly introduce these two types of reducers and summarize their differences.

Planetary reducer

A planetary reducer is a type of power transmission mechanism that utilizes a speed converter of gears to reduce the rotation of the motor to the desired number of revolutions, thereby obtaining a larger torque. The gear with fewer teeth on the transmission shaft of the planetary reducer meshes with the large gear on the output shaft to achieve deceleration.

Worm gear reducer, also known as worm gear reducer, is a power transmission element, which can be used together with ordinary motor, continuously variable transmission and other transmission products. Commonly used in high torque and low speed transmission mechanisms, electric motors and other higher speed power are passed through worm gear reducers to reduce speed and increase output torque. The worm gear reducer is installed between the electric motor and the working unit, and is powered by the electric motor. The worm gear reducer slows down, thereby transmitting the speed and torque from the output shaft to the working unit.

Differences between planetary and worm gear reducers

1. The internal structure is completely different

The planetary reducer is a cylindrical gear structure, while the turbine reducer is a worm gear structure. Technically, it is called a planetary reducer. The bearing capacity, accuracy, and stability of the planetary reducer are higher than those of the turbine reducer.

2. Different characteristics

The main characteristics of planetary reducers are compact structure, small return clearance, high accuracy, long service life, and large rated output torque.

The main feature of a worm gear reducer is its reverse self-locking function, which can have a large reduction ratio. The input and output shafts are not on the same axis or plane. However, it is generally large in size, low in transmission efficiency, and poor in accuracy.
