What are the important parameters for planetary gearbox selection

Industry news|2022-05-18| admin

Everyone knows that in the selection process of planetary gearbox, you need to know the parameters such as the rated torque, return clearance and size structure of the gearbox, but there are some more important parameters that need to be known. Next, we will introduce the selection of planetary gearbox Which parameters?

To put it simply, the focus of planetary gearbox selection is: the power of the motor, the reduction ratio of the planetary gearbox, the accuracy of the planetary gearbox, and the load condition of the gearbox. After understanding these parameters, it is easy to choose a suitable planetary gearbox.


1. Motor power.

In many cases, the type selection of the gearbox is carried out, or there is a need for replacement. After understanding the power of the motor, match the suitable type of gearbox according to the power.

2. Reduction ratio.

The speed ratio of the gearbox is diversified, the main one is 3, 4, 5, 7, 8, 10, the second is 9, 12, 15, 16, 20, 25, 32, 40, 64, and the third is Ratio 60, 80, 100, 120, 160, 200, 256, 320, 512, etc. are available for selection, and the specific selection is based on needs.

3. Accuracy requirements.

The accuracy requirements of the gearbox refer to the return clearance of the planetary gearbox, and the gear accuracy of the planetary gearbox is determined according to the accuracy requirements to narrow the model range.

4. Load factor

It is an important parameter for calculating the service factor of the gearbox. The load factor of the gearbox = load time ÷ total running time.

Because when the planetary gearbox is running, the load is intermittent. The load conditions in different time periods may be different, and it is more likely that there will be no load for a period of time.

The above is the relevant knowledge about the parameters of the planetary gearbox selection. The selection process needs to calculate and match the data of the planetary gearbox. Shenzhen Win-drive Automation Professional Technology provides the gearbox selection plan.
