Planetary Reducer

Introduction of planetary reducer

Why choose a planetary reducer?

1. Reduce the speed and increase the torque
2. Save space
The reducer is a relatively precise machine, which is generally used for low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed operating power is meshed with the gear with a small number of teeth on the input shaft of the reducer and the large gear on the output shaft. gears to achieve the purpose of deceleration. Geared motors can be used in almost any field, with excellent performance, high speed and axial load capacity.

Technical Charcteristics

SPECIAL SURFACE TREATMEN: The surface of the gearbox is treated with electroless nickel, and the upper and lower flanges are treated with anode surface treatment to improve environmental resistance and corrosion resistance. Abrasion, low temperature rise.
GREASE:  Select synthetic compound package base lubricating grease, oil leakage, anti-leftover, low noise, low wear and low temperature rise.
INPUT PORT: Adopting modular design, it can be easily adapted to servo motors of any brand and form, and magnesium-aluminum alloy is adopted, which can ensure the strength and force at the same time under the premise of reducing the weight.
GEAR MATERIAL: Use special 20CRMOTI to be heat-treated to the gear surface hardness of 60HRC, in order to obtain the best wear resistance and impact resistance toughness.
PLANETARY GEAR: Drum-shaped teeth are used for hard hobbing/grinding after carburizing to ensure that the gear accuracy class reaches JIS2.
INSIDE THE PLANET: "Metal cage needle roller bearings" are used to ensure that the reducer can withstand sufficient radial forces under the premise of stable installation.
INPUT SHAFT: It adopts double-cylinder compact structure to ensure the dynamic balance of the holding torque with the motor shaft and its own parts.
THE INPUT SHAFT IS CONNECTED WITH THE SUN WHEEL :Use internal and external spline transition fit to ensure that there is no risk of slippage in this connection.
OUTPUT END,INPUTEND: All use TC skeleton oil seals to ensure that the protection level of the reducer reaches IP65.

Advantages of planetary reducer

1.Powerful: High axial and radial overload capacity, high drive torque
2.Steady: One-piece molded shell integrates high precision, high rigidity and high strength
3.Flexible: Manufacturers can provide customers with all geared motor brakes and other options
4.Modular: Thanks to the modular structure design, the geared motor can be used in combination with other motors, powerful, stable operation, convenient and flexible
5.High torque: can be achieved and the torque load can be distributed to different gears. With a small volume, the planetary reducer can withstand higher torque than other reducers.
6.Cost savings: With the planetary reducer, the application can use a motor with a low power, greatly reducing the overall cost of the configuration.
7.High precision: Most planetary reducers produced today have extremely high precision.
8.Low noise: Even larger planetary gears have very low noise levels during operation.
9.High efficiency: The loss of power with a planetary gear train is small, so transmission efficiency can reach up to 97%.
10.High reduction ratio: Through the combination of multiple stages, higher reduction ratios can be attained.
11.Wide range of applications. Due to the high torque potential, high precision, high reduction ratio and compact characteristics of planetary reducers, they have unlimited potential uses in industrial applications.1. Reduce the speed and increase the torque.

Classification of planetary reducer

There are many types of reducers with different models, and different types have different purposes.

According to the transmission type, it can be divided into gear reducer, worm reducer and planetary gear reducer;

According to the number of transmission stages, it can be divided into single-stage and multi-stage reducers;

According to the gear shape, it can be divided into cylindrical gear reducer, bevel gear reducer and conical-cylindrical gear reducer;

According to the layout of the transmission, it can be divided into expansion type, shunt type and coaxial type reducer.

There are also harmonic reducers, pendulum reducers, etc.

We mainly provide planetary reducers (control motors, servo motors, stepping motors), which are characterized by high precision, commonly used 3 5 8 10 15 20 (level 1) compact structure, long life and high price With synchronous belt, screw rod, etc., you can consult us if you have any questions!

Selection Guide

Determine the use coefficient according to the load type, the number of starts and stops per hour and its working life：fs

1. According to the required torque Ts, the calculation torque is obtained according to the following formula：Tc=Ts*fs
2. From the required output speed n2 and input speed n1 transmission ratio：i=ni/n2
3. After determining Tc and i, according to the reducer rating table, select the gearbox model that is closest to the calculated value and meets the following conditions：TN≥Tc
4. Safety factor[S]

*The safety factor can be selected according to the table below
