What is backlash in planetary reducer? How can it be reduced?
2024/9/1

Usually, when we need a huge reduction in speed but high torque in a very short space. we use the planetary reducer, the planetary gearbox( also called planetary gear reducers, planetary reducer,  planetary gearhead, planetary gearboxes) has the features of high torsional rigidity, high reduction ratio, and compact design, and has infinite potential uses in industrial applications. In the planetary reducer, we also say that the lower the backlash, the higher the performance. the but do you know where is backlash and how can backlash influence it?

What is backlash? Why can't it be zero?

Backlash is the gap or clearance between two workpieces while combined. it means the gap between meshed gear teeth.

1.Gear backlash is required to keep gears meshing without getting stuck and also provide enough lubrication space.  

2.The backlash is also helpful to the assembly and maintenance of a planetary gear so that it can prolong the service life of the planetary gear.  

3.If the planetary gearbox overheats and teeth damage, backlash can ensure the planetary gearbox works smoothly. so this gap is very important for the gear machining error and the gear deformation 

Backlash is commonly measured in arc minute (arcmin) or arc-second (arcsec).  the backlash of the planetary gearbox can be divided into ≦1 arcmin, ≦3 arcmin, ≦5 arcmin, and ≦7 arcmin. There is no The smaller the backlash, the higher the precision and the higher the relative price.  higher accuracy,  the more costs. The planetary gearbox backlash ≦1 arcmin for precision instruments, robotics, or machine tools. Therefore, controlling and reducing the backlash of the planetary gearbox is very important.

 How to reduce backlash in planetary gearbox?

You can reduce the backlash by specifying higher precision gears or by custom fitting the gears.

It is usually used to reduce the output speed of the drive motor and increase the output torque to achieve the ideal transmission effect. it can be used in robots, CNC machine centers, woodworking processing centers, etc.
