Q: SKF bearing dynamic load rating of Cr (N), the rated static load Cor (N) what is the meaning that what is the difference?
Load bearing SKF bearing dynamic load is when the plant is in operation?
Answer: A, rated radial (or axial): refers to the dynamic load of rolling constant radial load SKF bearing theory can bear (or constant axial load). SKF bearings in the load, rated life of SKF bearing one million rpm. This mainly reflects the ability of resistance to SKF bearing rolling contact fatigue.
Basic rated radial bearing and thrust bearing SKF SKF dynamic loads are called radial basic rated dynamic load and axial basic rating, represented by Cr and Ca.
Two, the radial (or axial) basic static load rating: refers to the maximum load and rolling body raceway contact center and the calculation of contact radial stress equivalent static load (center of the axial static load). For the self-aligning ball bearing SKF, 4600MPa; SKF for radial ball bearings and thrust ball bearing SKF, other types of 4200MPa; for the radial and thrust roller bearing SKF, 4000MPa.
The total permanent deformation of the rolling elements and raceways contact stress in these produced about 0.0001 times the diameter of the rolling body.
SKF bearing too much to bear the static load and low speed or under impact load, roller and raceway contact surface will produce local permanent deformation. The deformation increases with the increase of load, beyond a certain limit of words, will affect the normal rotation. Basic rated radial bearing and thrust bearing SKF SKF static load are basic static radial load rating and axial basic static load rating, represented by Cor and Coa.
Rated dynamic load and static load ratings for each manufacturer has a different design, its value has bigger difference. Values of each manufacturers were recorded in each sample. You in the process design of the device, dynamic load SKF bearing load is not rated SKF bearing, should be in SKF bearing radial load and axial load.
