Understand how to select bearing model and specification for motor model
Author:admin Date:2023-01-28
The selection of motor bearings can be carried out as follows:
1. Select according to the limit speed. In the bearing table, all bearings are the main parameters with the limit speed. It is only necessary that the shaft speed does not exceed the limit speed of the bearing.
2. It is determined according to the load on the shaft. In the bearing table, all bearings list the main parameters of "rated dynamic load" and "rated static load". When selecting, it is not necessary to exceed the corresponding standard value.
3. The balance of rotating speed and load on the shaft shall be considered comprehensively, and it is not necessary to ignore the other items in the figure, otherwise, the bearing will be invalid prematurely and cause safety accidents.
4. After knowing the motor model, it means that you have already known the detailed structural mechanics calculation, otherwise you will not get the output power of the motor. Even though there are detailed structural mechanics calculations, there are actual main parameters for the load on the shaft (including the shaft speed), which is the basis for selecting the motor bearing.
5. When selecting motor bearings, don't forget one element, that is, the lubrication standard. (oil bath lubrication, boundary lubrication, pressure lubrication, manual lubrication, thin oil lubrication, dry oil lubrication, no lubrication) An organization with good lubrication standard can select a slightly lighter bearing. If the lubrication standard is poor, or the lubrication standard is not, it needs to select a stronger bearing.
6. Just as the size of TV can be selected according to the total area of the room, although there is an approximate reference specification, there can be some malleable selection space within a certain range.
