1. What is the life of the bearing?
For a single bearing, the number of revolutions of one ring relative to the other before fatigue expansion of one ring or rolling element material first occurs is called the bearing life. Due to differences in manufacturing accuracy, material homogeneity, etc., even bearings of the same material, same size and produced in the same batch work under exactly the same conditions, their lifespans will be very different.
2. What are the main failure modes of rolling bearings?
The main ones are: pitting corrosion, plastic deformation, abrasive wear, adhesive wear, rust, bearing burn, etc.
3. What is the basic rating life of the bearing?
According to the number of revolutions (in millions of revolutions) or the number of working hours before pitting damage occurs in 10% of the bearings in a set of bearings, and 90% of the bearings do not suffer from pitting damage, the life of the bearing is taken as the life of the bearing. It is called the basic rating life, and it is expressed as L10.
4. What is the basic dynamic load rating of the bearing?
When the basic rated life of the bearing is exactly one million revolutions, the load value that the bearing can bear is called the basic dynamic load rating of the bearing, which is represented by C. For radial bearings, it refers to pure radial load, which is represented by Cr; for thrust bearings, it refers to pure axial load, which is represented by Ca.
5. What is the equivalent dynamic load of the bearing?
If the rolling bearing bears radial and axial combined loads at the same time, in order to compare the bearing life under the same conditions, the actual load must be converted into an equivalent dynamic load consistent with the load conditions for determining the basic dynamic load rating when calculating the life of the bearing. , denoted by P.
6. Why should the static load be calculated for rolling bearings?
Static load refers to the load acting on the bearing when the relative speed of the bearing ring is zero or the relative speed is extremely low. In order to limit the excessive contact stress and permanent deformation of rolling bearings under static load, static load calculation is required.
