Rolling torque loads and life
1. Start torque starting torque
So that a bearing ring or gasket relative to another stationary rings or gaskets starts rotating the torque required.
2. The rotational torque running torque
When a bearing ring or washer is rotated, the ring or gasket to prevent another motion torque required.
3. The radial load radial load
Vertical load acting on the bearing axis direction.
The axial load axial load
Load applied parallel to the bearing axis direction.
5. The static load static load
When the relative rotational speed of the bearing rings or washers to zero (or thrust bearing to the heart) or when the rolling elements in the rolling direction when no motion (linear bearings), the role of the load on the bearing.
6. The dynamic load dynamic load
When the bearing ring or gasket relative rotation (radial or thrust bearings) or when the rolling element in the direction of movement when scrolling (linear bearings), the role of the load on the bearing.
7. equivalent load equivalent load
General term used to calculate the theoretical load, in certain situations, in which the theoretical load bearing acts as the actual load to bear.
8. The radial (axial) Basic rated static load basic static radial (axial) load rating
And the rolling elements and raceways total amount of permanent deformation corresponding radial static load (center axial static load). If at zero load, roller and raceway (roller bearing) is the total amount of permanent deformation or presumed normal bus (line of contacts), the contact stress at the maximum, the rolling element and raceway contact of rolling elements produced at 0.0001 times the diameter. Single row angular contact bearings for radial load rating radial component causes the bearing rings relative to each other pure radial displacement of the load.
9. The radial (axial) basic dynamic load rating basic dynamic radial (axial) load rating
Constant radial load (constant axial load center), under the load, the rolling bearing can theoretically withstand 1 million revolutions of the basic rating life. Single row angular contact bearings for the radial load rating for the cause of the bearing rings relative to pure radial displacement of the load of each component.
10. Life (refer to a set of bearings) life
Before a collar or a washer or a rolling element bearing material fatigue expanded for the first time, a collar or a number of rotations relative to the other rings or a gasket washer. Life also by the number of operating hours at a given constant speed to represent.
11. can * (referring to bearing life) reliability
A group of nearly identical rolling bearings operating under the same conditions expected to reach or exceed a specified percentage of the bearing life. A bearing can be * To this end bearings reaches or exceeds a predetermined life expectancy.
12. The rated life rating life
The basic dynamic load rating radial or axial basic rated dynamic load predicted value based life.
13. The basic rating life basic rating life
And 90% * of the association can be rated life.
14. The life factor life factor
In order to obtain and given nominal lifetime corresponding basic dynamic load rating radial or axial basic dynamic load rating, equivalent dynamic correction factor applied to the load.
15. Bearings plummer block
An assembly radial bearings and housing combined, in line with the bearing axis parallel to the support surface of the base plate for mounting screws.
16. Vertical Block plummer block housing
Rolling fitted with seat.
17. flanged housing flange seat
Radial flange and on the axis perpendicular to the bearing surface of a bearing seat for its use of the mounting screw holes.
18. The adapter sleeve adapter sleeve
Having a cylindrical bore of the axial opening of the sleeve, and the outer surface of the small end has a conical external thread. For a tapered bore bearing installed (with lock nut and lock washer) in a cylindrical outer surface of the shaft.
19. The withdrawal sleeve withdrawal sleeve
Having a cylindrical bore axial opening of the sleeve, and the outer surface of the big end has a conical external thread. Used to have a tapered bore bearing installation or removal (with nuts) on the axis of the cylindrical outer surface.
20. locknut locknut
Having a cylindrical outer surface and an axial groove female screw with lock washer and an outer annular plate claw hand nut. Rolling bearings for axial positioning.
21. The lock washer lockwasher
There are many thin steel washer outside claw. An outer claw for locking nut, an inner claw insert an adapter sleeve or shaft axial slot.
22. The eccentric eccentric locking collar
One end opposite the hole eccentric groove rims, mounted on the outer end of equal elongation eccentric spherical bearing inner ring. The inner ring relative to the inner ring rotating eccentric tightened, then tighten jacking wire so that the fastening shaft.
23. The concentric sleeve concentric locking collar
Mounted on the outer rims of the spherical bearing inner ring width, Covered wire threaded into the hole in the inner ring and is in contact with the shaft
