Planetary reducer（planetary gearbox reducer, planetary gearboxes, planetary reducer, gear reducer, reduction gear) can be used more and more popular because of its compact size, higher efficiency, and low noise level. But do you know how to test its quality when you get the planetary reducer? and do you know how to distinguish your planetary gear is bad? In this article, you will find the answer:

The key components will influence the quality of the planetary reducer

1. Gear tooth quality and meshing mechanism

2. Seals and gaskets

3. Cases and housings

4. Shafts

5. Pinions

6. Bearings

Also, the below test is necessary to do for the planetary reducer:

1. Gearbox Backlash Tests

Backlash in a gearbox can reduce torque efficiency and cause wear. 

2. Spin Test

torque transmission, noise levels, centrifugal force losses, and temperature need to be tested in this action. In total, it tests determines the efficiency of the planetary reducer.

3. Vibration Test

It has important significance in identifying undesirable noise and potential wear and tear on the bearings.

4. Planetary Gearbox Efficiency Test

It can find the reason why inefficiency in the gearbox, maybe by churning lubricants, seals, or bearings. 

5. Planetary Gear Mesh Alignment Test

6. Overheating Planetary Gearbox Testing

Overheating can lead to wear and reduce the service life of a gearbox.

How do you know if your transmission planetary gear is bad?

If you can't open up your planetary hub when you suspect there is something within the planetary reducers. Listening to abnormal sounds and vibrations. if the sounds and vibrations are different from normal like new sounds or rattles develop, it shows that there is something in the planetary gearbox.

If you open up your gear hub, here are the signs of wear to remind you to change a new planetary gear

1. Worn gear teeth that look more pointed than squared

2. Cracking (this starts at the root of the gear teeth where the stress is the highest) surface damage, such as pits, and scuffing.

3. Bent gear teeth

Here you need to note that:

Any bits of metal that chip off or break off are going to stay within the gear system, it will cause the wear.

Gear oil can make sure that your planetary gear system doesn't wear out earlier.  Good lubrication is key to a system that runs efficiently and lasts for a long time. It's also important to keep your gear oil as free from contamination as you can.

RicoCNC supplies a series of planetary gearboxes, no matter which brands planetary gear box reducers, like NIDEC reduction gear, EISELE, Bonfiglioli, and NAIF, and undergo a rigorous quality inspection before they are shipped out. Welcome your inquiry, we will be always here.
