1. Starting torque
The torque required to rotate a bearing ring or washer relative to the opening of another fixed ferrule or washer.
2. Rotational torque
When a bearing ring or washer rotates; the torque required to block the movement of the other ring or washer.
The effect is the load in the direction of the axial direction of the straight bearing.
The effect is the load in the direction of the axis of the parallel bearing shaft.
When the relative rotational speed of the bearing ring or washer is zero (central or thrust bearing) or when the rolling element does not move in the direction of rolling (linear bearing); the effect on the bearing.
When the bearing ring or washer is relatively rotated (central or thrust bearing) or when the tumble element is moving in the direction of rolling (linear bearing); the effect on the bearing.
The general term used to account for theoretical loads; in certain situations; the bearing appears to bear the practical load under the theoretical loading effect.
Radial static load (intermediate axial static load) corresponding to the total eternal deformation of the roll and raceway. If under zero load; roller and raceway (roller bearing) are or assumed to be normal busbars (full line When touched; under the maximum touch stress; the total eternal deformation occurring at the roll and raceway touch is 0. 0001 times the diameter of the roll body. For single row angular touch bearings; the radial extra load is such that the bearing rings are opposite each other. The radial weight of the load with pure radial displacement.
Stable radial load (stable intermediate axial load); under this load; the rolling bearing can theoretically saturate the fundamental extra life of 1 million rpm. For single-row angular touch bearings; the radial additional load is the resulting bearing sleeve The weight of the load relative to each other with a pure radial displacement.
10. Life (refers to a set of bearings) life
The number of revolutions of a ferrule or a washer or a tumbling element of the bearing is initially shown before the fatigue is enlarged; the number of revolutions of one ferrule or one washer relative to the other ferrule or a washer. The life is also available at a given steady speed. Working hours to indicate.
11. Reliability (referring to bearing life) reliability
A group of nearly identical rolling bearings operating under the same conditions. The percentage of bearings that wish to reach or exceed a certain number of lifespans. The reliability of a set of bearings is the probability that the bearing will reach or exceed the ruled life.
12. Extra life rating life
The guess value of the lifespan based on the radial fundamental extra dynamic load or the axial fundamental extra dynamic load.
13. Basic extra life
Additional lifespan associated with 90% reliability.
14. Life factor
15. Bearing block plummer block
A combination of a radial bearing and a seat; a support plate on the support surface parallel to the bearing axis.
16. Vertical block plummer block housing
Mount the bearing for the rolling bearing.
17. Flanged housing
a seat having a radial flange and a screw hole for the device on the outer surface of the support shaft.
An axially open sleeve having a cylindrical bore; the outer surface is conical and has a small end with an external thread. For use with a tapered bore bearing assembly (with lock nut and lock washer) On the axis of the appearance.
19. Withdrawal sleeve withdrawal sleeve
a sleeve having a cylindrical inner bore axially open; the outer outer surface is conical and the outer end is externally threaded. For mounting the tapered bearing on the shaft of the outer cylindrical outer surface (with a nut).
20. Lock nut locknut
Screw nut with cylindrical outer surface and axial groove; lock the nut with an outer claw of the lock washer and the annular wrench. It is used for axial positioning of the rolling bearing.
twenty one. Lock washer lockwasher
A thin steel plate washer with many external claws. One outer claw is used to lock the nut; one inner claw is inserted into the axial groove of the adapter sleeve or shaft.
twenty two. Eccentric locking collar
a grooved steel ring having a pain in the inner hole at one end; the device is in the flat end of the inner spherical bearing with a flat and painful extension end. The inner ring is rotated relative to the inner ring to fix the inner ring; then the top wire is fastened to fix it Tight on the shaft.
twenty three. Concentric sleeve
The rim is mounted on the wide inner ring of the outer spherical bearing; the top wire is screwed into the hole in the inner ring and touched with the shaft.
