Just learned in the selection of motor bearings, in addition to the deep groove ball bearing, the rolling bearing to meet the following conditions: 1. the C3 clearance speed is higher than the reference speed bearing 70%; so choose C3 clearance of deep groove ball bearings at what time the 2. temperature greater than 10 DEG C when the inner and outer rings? Younger brother every time with the coefficient of linear expansion and temperature rise to reduce the amount of clearance, and then refer to the bearings and shaft and bearing seat to determine the use of clearance, so that there are other deficiencies? Request for comment
According to the estimation, the radial clearance reduction due to interference is chosen
In fact, in many cases, if the accessories do well, CNH, I think it is also a good choice, of course, depending on the working conditions I think, because there are many differences in cooperation
In the selection of motor bearings, according to the user's use results, deep groove ball bearings are generally the upper half of the C3, that is, the clearance value of the lower half, more suitable for the motor in the light load, medium and high speed. The normal work windage involves many factors, and the calculation can only solve most of the problems. In many typical application conditions, there is a mature design, and comparing each other is a more reliable method.
