Characteristics Of Structure And Properties Of Five Kinds Of Bearings
The structure and characteristics of thrust tapered roller bearings?
Because of thrust tapered roller bearings roller of tapered roller and structure by rolling bus Raceway bus collection with the washer on the bearing axis at a point on the line and rolling surface forming pure roll, ultimate speed higher than the cylindrical roller thrust bearing.
Tapered roller thrust bearings can withstand the unidirectional axial loading.
Thrust tapered roller bearing type codes to 90000.
Due to low production of thrust tapered roller bearings, the plant has been producing models for non-standard dimensions and standard size series, less production, so there is no such bearing dimension national standards in place.
Thrust angular contact ball bearing structure and performance characteristic?
Angular contact thrust ball bearings contact angle is 60 ° of angular contact thrust ball bearings double direction angular contact thrust ball bearings, mainly used in precision machine tool spindles, and double row cylindrical roller bearings are used in conjunction, can be subjected to bi-directional axial load, high precision, high rigidity, low temperature, high speed, easy to disassemble and so on.
Structure and properties of double row tapered roller bearing characteristics
Structure of double row tapered roller bearing range maximum is 35000, have a double roller Cup, and two inner rings, there is a spacer between the two inner rings, changing the thickness of the spacer clearance can be adjusted. This type of bearing radial load axial load in two directions at the same time, restrictions within the axial internal clearance of the bearing axis and axial displacement of the shell.
The structural characteristics of tapered roller bearings.
Tapered roller bearing type 30000, tapered roller bearings are separable bearings. Under normal circumstances, especially in the GB/T307.1-94 involved in the rolling bearings-radial bearings-tolerance within the size range of the tapered roller bearing outer ring is completely interchangeable with the component are used interchangeably. Point of view as well as in the outer ring raceway diameter sizes with the same dimensions are standardized provisions. Is not allowed in the design and manufacturing changes. Tapered roller bearing outer ring and universal around the world exchanged between components.
Tapered roller bearings are mainly used in under a radial load of radial and axial combined loading. Compare with angular contact ball bearings, bearing capacity, low speed limit. Tapered roller bearings can accommodate axial loads in one direction, to limit the axial displacement of the shaft or housing in one direction.
Characteristics of deep groove ball bearings?
Structure of deep groove ball bearings on each ring with a cross section around the Equatorial circumference of the ball one-third the continuous Groove Raceway.
Deep groove ball bearings are mainly used in radial load, and can also withstand axial loads.
When the radial clearance of bearings increases, has the nature of angular contact ball bearings to withstand alternating axial loads in both directions.
Compared with other types of bearings of the same size, this kind of bearing friction coefficient, high speed, high precision, is preferred by the user selection of bearing type.
Deep groove ball bearings is simple in structure, easy to use, is the largest production batch, the widest range of application of a kind of bearings.
