Motor bearing the relations of dynamic load and static load

Motor bearing static load including load (does not change with time Such as weight) And load changes slowly and can omit the inertial force of quasi static load; Motor bearing dynamic load of the quick action of impact load (including a short time Such as air hammer) Intercropping, at any time change of load cycles ( Such as air compressor crankshaft) And the random load cycles. Cr is rated dynamic load, it is under the rotational state of maximum load capacity, unit is KN; Co is a static load rating. It is not the load capacity under the rotation. Basic dynamic load rating C is used to calculate the bearing under the dynamic stress, namely a while under load bearing. The numerical said according to ISO 281:1990 standard, providing 1 million turn basic rating life of bearing load. Assumed load size and direction of the same, for the radial for radial load, is applied to center for thrust bearing axial load. Axial load, load along the axial direction. Radial load, perpendicular to the axis of the direction of the load. The two are radial load calculation. In short, it is a very professional knowledge, it is abstract. It is better to choose what brand of motor bearing is what brand reference samples. Because each brand bearings technical parameters are distinct. A: class, second class refers to what type of bearing? Next: what is the speed of the deep groove ball bearings
