4 faults may occur when the planetary reducer gearbox operates in a harsh environment- Shanghai SGR Heavy Industry Machinery Co., Ltd.

Planetary reducer gearboxes are a type of transmission device commonly used in the mechanical field, which converts high-speed input into low-speed high-torque output. Planetary gear reducers are mainly used in various aspects of industrial and general machinery fields. Due to different operating scenarios, the operating environment will also be different.

Shanghai SGR Heavy Industry Machinery Co.,Ltd. is a professional gear reducer R&D and production manufacturer, focusing on the R&D and production of various planetary reducer gearboxes , double enveloping worm gear reducers and special reducers. After more than 15 years of deep cultivation in gear reducers, SGR found that maintaining a relatively good and stable operating environment plays a great role in improving the performance of planetary reducer gearboxes.

On the contrary, planetary gear reducers may have various problems and abnormalities in harsh operating environments. These 4 main problems and abnormalities include:

(1) Failures caused by abnormal temperature

When the operating environment temperature of the planetary gear reducer is too high, the lubricating oil will become thinner, reducing the lubrication effect of the gears and bearings, which may increase friction and wear, and ultimately affect the life of the reducer.

Conversely, when the operating environment temperature of the planetary gear reducer is too low, the lubricating oil will become viscous, making the operation of the planetary reducer gearbox more difficult, which may cause difficulty in starting, unstable operation, and increased power loss. Both too high or too low are not good for the planetary reducer gearboxes.

(2 )Failures caused by abnormal ambient humidity and particulate matter

When the humidity of the planetary gear reducer is too high, it may cause corrosion of the metal parts inside the reducer and may also cause the seal to fail.

If the operating environment of the planetary gear reducer is seriously polluted by particulate matter, it may enter the planetary reducer gearbox, causing gear wear and bearing damage.

For example, particulate matter in the environment can act as abrasives, causing accelerated wear on gear teeth and bearing surfaces.The combination of humidity and particulate matter can worsen abrasive wear, affecting the gear reducer's performance.

High humidity levels can introduce moisture into the lubrication system, leading to lubricant contamination.Particulate matter can also contaminate the lubricant, reducing its effectiveness and leading to increased wear on components of the planetary reducer gearboxes.

(3) Failures caused by abnormal special acid-base environment

Some industrial environments may contain acidic or alkaline chemicals that can attack the metal parts of the planetary gear reducer, causing some kinds of failures.

Acid-base environments can cause corrosion on the planetary gear reducer's components, leading to degradation of materials and reduced performance. Corrosion can weaken the structure of the gear reducer and eventually lead to failure if not addressed.

Acidic or basic environments can degrade the lubrication inside the planetary reducer gearboxes, leading to insufficient lubrication between gears.Inadequate lubrication can result in increased friction, overheating, and accelerated wear of components.

In some cases, special acid-base environments can accelerate the degradation of materials used in the gear reducer.Materials may lose their strength and durability, compromising the overall performance and reliability of the gear reducer.

(4) Failures caused by other harsh operating environments

Harsh environments mainly include frequent vibration shocks, high loads, and frequent starts and stops, which may cause the components of the planetary gear reducer to loosen or be damaged, affecting the operating stability. The planetary gear reducer is subjected to greater loads and frequent starts and stops, which may cause fatigue and damage.

In addition, harsh operating environments often lead to wear, leakage and other faults in planetary gear reducers. In order to deal with these problems, appropriate measures are usually required. When purchasing, mechanical and industrial companies can choose durable reducers suitable for harsh environments, conduct regular inspections and maintenance, and use appropriate lubricants and seals to ensure that the planetary reducer gearboxes can operate efficiently in harsh environments and extend its life.

Finally, SGR recommends that you regularly check the operation of the planetary gear reducer. If you find any abnormal noise, abnormal vibration or other abnormal performance, please contact the planetary gear reducer manufacturer in time or repair it in time.（Author: SGR, Angie Zhang）
