The role of tapered roller bearings and use

wallpapers Resource 2020-05-21
Tapered roller bearings mainly bear combined radial and axial loads. The bearing capacity of the bearing depends on the raceway Angle of the outer ring. The larger the Angle, the greater the carrying capacity. This type of bearing is a split bearing, according to the number of rows of rolling elements in the bearing is divided into single row, double row and four row tapered roller bearings. The clearance of single-row tapered roller bearings shall be adjusted by the user during installation. According to user's requirement, the clearance of double row and four row tapered roller bearings has been given at the factory without user's adjustment. Tapered roller bearings have tapered inner and outer raceways and are arranged with tapered rollers in between. The projection lines on the conical surface converge at the same point on the bearing axis. This design allows tapered roller bearings to withstand composite (radial and axial) loads. The axial load capacity of the bearing depends mainly on the Angle of contact Angle.

The higher the axial load capacity. The Angle is represented by the calculated coefficient e; The greater the e value, the greater the contact Angle, and the greater the applicability of the bearing to bear axial load. Tapered roller bearings are usually of a split type, i.e. the tapered inner ring assembly consisting of an inner ring with a roller and cage assembly can be mounted separately from the tapered outer ring (outer ring).

 
Tapered roller bearings are used in automobile, steel rolling mill, mining, metallurgy, plastic machinery and other industries. The second reason why tapered roller bearings appear in the installation process is that the bearings are being assembled, and the inner and outer rings are tilted during the assembly process. Or the load is in the process of assembly and assembly and forms the bearing. . When installing tapered roller bearings, stop according to the working specification. If there are many achievements, if the form or method of the device is not used, the bearing surface and the bone surface of the bearing will form a winding line. The deep groove ball bearing device indirectly reflects the accuracy, life and function of the bearing. Although tapered roller bearings are of better quality in all respects, rolling bearings are precision components that must be used with care. No matter how much the bearing is used, if it is not used properly, it will not happen. There are several considerations regarding the use of bearings:

(1) keep tapered roller bearings and their surroundings clean.

 
Even small dust particles that are invisible to the eye can have a bad effect on the bearings. Therefore, keep the surroundings clean so that dust does not invade the bearings.
 
(2) use with care and care. In the use of taper roller bearing given a strong impact, will produce marks and indentation, become the cause of the accident. In severe cases, cracks and fractures may occur, so pay attention.
 
(3) use the right tools instead of the right tools.
