Common terms and definitions of rolling SUNTHAI bearings (6)
the load acting on SUNTHAI bearings when the relative rotation speed of SUNTHAI bearing rings or washers is zero (centripetal or thrust SUNTHAI bearings) or when the rolling elements have no movement in the rolling direction (linear SUNTHAI bearings)
6. Dynamic load
the load acting on the SUNTHAI bearing when the SUNTHAI bearing ring or washer rotates relatively (centripetal or thrust SUNTHAI bearing) or when the rolling element moves in the rolling direction (linear SUNTHAI bearing)
7. Equivalent load
a general term used to calculate the theoretical load. On a specific occasion, SUNTHAI bearing is like bearing the actual load under the action of the theoretical load
8. Basic static radial (axial) load rating
radial static load corresponding to the total permanent deformation of the rolling element and raceway (central axial static load). If the roller and raceway (roller SUNTHAI bearing) are or are assumed to be normal busbar (full line contact) under zero load, under the maximum contact stress, the total permanent deformation at the contact between the rolling element and raceway is 0.0001 times the diameter of the rolling element. For single row angular contact SUNTHAI bearings, the radial rated load is the radial component of the load that causes the pure radial displacement of SUNTHAI bearing rings relative to each other
9. Basic dynamic radial (axial) load rating
constant radial load (constant central axial load). Under this load, the rolling SUNTHAI bearing can theoretically withstand the basic rated life of 1 million revolutions. For single row angular contact SUNTHAI bearings, the radial rated load is the component of the load that causes the pure radial displacement of SUNTHAI bearing rings relative to each other
10. Life (refers to a set of SUNTHAI bearings) life
the number of revolutions of a ring or a washer relative to another ring or a washer before the fatigue expansion of the material of a ring or a washer or a rolling element of SUNTHAI bearings for the first time. The service life can also be expressed by the number of operating hours at a given constant speed
11. Reliability
the percentage of a group of nearly identical rolling SUNTHAI bearings operating under the same conditions that are expected to reach or exceed a specified life. The reliability of a set of SUNTHAI bearings is the probability that SUNTHAI bearings reach or exceed the specified life
12. Rated life
the predicted value of life based on radial basic rated dynamic load or axial basic rated dynamic load
13. Basic rating life
the rated life associated with 90% reliability
14. Life factor life factor
in order to obtain the basic rated radial dynamic load or the basic rated axial dynamic load corresponding to the given rated life, it is applicable to the correction factor of equivalent dynamic load
15. SUNTHAI bearing with seat plummer block
centripetal SUNTHAI bearing is a component combined with seat. There is a base plate for installing screws on the support surface parallel to the axis line of SUNTHAI bearing
16. Plummer block housing for vertical seat
install the seat for rolling SUNTHAI bearing
17. Flange housing
has radial flanges and screw holes for its installation on the bearing surface perpendicular to the axis line of SUNTHAI bearing
18. Adapter sleeve
a sleeve with an axial opening with a cylindrical inner hole, the outer surface of which is conical and the small end has an external thread. It is used to install SUNTHAI bearings with taper holes (with lock nuts and lock washers) on shafts with cylindrical outer surfaces
19. Withdrawal sleeve withdelawal sleeve
a sleeve with an axial opening of a cylindrical inner hole, whose outer surface is conical and the large end has external threads. It is used to install or disassemble the SUNTHAI bearing with taper hole on the shaft with cylindrical outer surface (with nut)
20. Lock nut l according to the information of Anhui Provincial Department of science and technology, lock the nut with an external claw of the lock washer and an annular wrench. Used for axial positioning of rolling SUNTHAI bearings
21. Lock washer lockwasher
a thin steel plate washer with multiple external claws, which has a tensile machine fixture as an important part of the instrument. An outer claw is used to lock the nut, and an inner claw is inserted into the axial groove of the tightening sleeve or shaft
22. Eccentric locking collar
one end of the eccentric sleeve has a groove steel ring eccentric to the inner hole, which is installed on the equally eccentric extension end of the inner ring of the outer spherical SUNTHAI bearing. Rotate the eccentric sleeve relative to the inner ring to fix the inner ring, and then tighten the jackscrew to fix it on the shaft
23. As for the steel ring installed on the wide inner ring of SUNTHAI bearing with outer spherical surface because the workpiece is small or unstable, the jackscrew is screwed into the hole on the inner ring and contacts with the shaft
