Five types of bearing structure, performance characteristics
Thrust tapered roller bearing structure, performance characteristics:
Since the rolling elements in the thrust tapered roller bearing are tapered rollers, the rolling busbars of the rolling busbars and washers meet at a certain point on the axis line of the bearing in the structure, so the rolling surface can form a pure rolling, limiting rotation speed. Higher than thrust cylindrical roller bearings.
Thrust tapered roller bearings can withstand uniaxial load.
Thrust tapered roller bearing type code 90000.
Since the production of thrust tapered roller bearings is small, the models that have been produced in various plants are mostly non-standard external dimensions, while the series of standard external dimensions and varieties are less produced. Therefore, there is no national standard for the external dimensions of such bearings.
Axial angular contact ball bearing structure, performance characteristics:
Axial angular contact ball bearing contact angle is generally 60 ° commonly used thrust angular contact ball bearings are generally two-way thrust angular contact ball bearings, mainly used for precision machine tool spindles, commonly used in conjunction with double row cylindrical roller bearings, can withstand bidirectional shaft The load has the advantages of high precision, good rigidity, low temperature rise, high rotation speed, convenient assembly and disassembly.
Double-row tapered roller bearing structure, performance characteristics:
Double-row tapered roller bearings have a variety of structures. The maximum amount is 35000. There is a double raceway outer ring and two inner rings. There is a spacer ring between the two inner rings. The clearance can be adjusted by changing the thickness of the spacer ring. This type of bearing can bear two-way axial load while bearing radial load, and can limit axial displacement of the shaft and housing within the axial clearance of the bearing.
Tapered roller bearing structure features:
The type of tapered roller bearing is 30,000, and the tapered roller bearing is a separate bearing. Under normal circumstances, especially in GB/T 307.1-94 "Rolling Bearing Radial Bearing Tolerance" in the size range of tapered roller bearings between the outer ring and the inner component is 100% can be used interchangeably. The outer ring angle and outer raceway diameter dimensions have been standardized with the same dimensions as the outer dimensions. It is not allowed to change it during design and manufacturing. So that the outer ring and inner components of the tapered roller bearing can be universally interchanged between the world.
Tapered roller bearings are mainly used to withstand the radial and axial combined load mainly radial load. Compared with angular contact ball bearings, the bearing capacity is large and the limiting speed is low. Tapered roller bearings can withstand axial loads in one direction and can limit the axial displacement of a shaft or housing in one direction.
Deep groove ball bearing features:
Each ring of the deep groove ball bearing in the structure has a continuous groove type raceway having a cross-section approximately one third of the equatorial circumference of the ball.
Deep groove ball bearings are mainly used to withstand radial loads and can also withstand certain axial loads.
When the radial clearance of the bearing increases, it has the properties of angular contact ball bearings and can withstand alternating axial loads in both directions.
Compared with other types of bearings with the same size, this type of bearing has a small coefficient of friction, high limit rotation speed and high precision, and is the preferred type of bearing for user selection.
Deep groove ball bearing is simple in structure and easy to use. It is the largest production batch and the most widely used type of bearing.
