How to Choose the Model of Planetary Reducer？
The planetary gear reducer is the main type of reducer equipped with servo motors, which means that this product is basically equipped with our model of reducer. Of course, some consumers may have special needs, so they choose other types of reducers. However, based on the current selection situation of the vast majority of consumers in the market, They may be more willing to use this device. Of course, when choosing the equipment for these reducers, it is important to have a clear understanding of their model in advance, as the reduction ratio of our model is different.
- Determine the reduction ratio of planetary gear reducers
After determining the reduction ratio of the planetary gear reducer we need, you can also multiply the rated torque of the servo motor you need by the reduction ratio to obtain a number that must be less than the rated output of similar reducers on the product model record,
- Considering the overload capacity of the drive motor
The drive motor is not just required to meet normal operating conditions. Sometimes, it may reach some extreme conditions during production. However, if our equipment does not keep up with these extreme conditions, it is very likely that the equipment will malfunction. Therefore, it is necessary to consider these aspects, Of course, everyone must also consider the overload capacity of the driving motor and the maximum output current required in practice.
- Consider the return clearance of the reducer
It is necessary to consider the return clearance of the reducer, because the smaller the return clearance, the higher the accuracy, cost, and also the higher the cost. When selecting, users must choose a series of reducers that meet their own accuracy. Only in this way can they meet the production factors of everyone’s series, and we can also consider radial force and average lifespan.
