Tapered roller bearings refer to radial thrust bearings with rolling bodies as tapered rollers. A small cone angle and large cone angle two. The small cone angle is mainly subjected to radial and axial joint loads based on radial load, which is often used in double use, reverse installation, internal and external seats can be installed separately, and the radial and axial clearance can be adjusted in the installation and use. The big cone angle is mainly subjected to axial and radial joint loads mainly with axial load, which is generally not used alone to bear pure axis. The load can be used as a pair of configurations (relatively installed at the same name) to withstand pure radial load.
Tapered Roller Bearing Feature
The type of tapered roller bearing is 30000, tapered roller bearings are separable bearings. Generally, one hundred percent can be used interchangeably between the outer ring and the inner components of the tapered roller bearing in the range of dimensions involved in the tolerance of the GB/T307.1-94 rolling bearing centripetal bearing.
The main type we make,
The angle of the outer ring and the diameter of the raceway are standardized with the same size. It is not allowed to change at the time of design and manufacture. The outer ring and inner components of the tapered roller bearing can be exchanged all over the world.
Tapered roller bearings are mainly used to bear radial load combined with radial load. Compared with angular contact ball bearings, the bearing capacity is high and the limit speed is low. Tapered roller bearings can withstand axial loads in one direction, which can restrict the axial displacement of the shaft or shell in one direction.
Tapered Roller Bearing Application
Tapered roller bearings mainly bear radial and axial combined loads. Bearing capacity depends on the raceway angle of the outer race, and the greater the angle is.
The greater the capacity is. The bearings are separable bearings. According to the number of rollers in bearings, they are divided into single row, double row and four row tapered roller bearings. Single row tapered roller bearing clearance needs the user to adjust when installation; double row and four row tapered roller bearing clearance has been given at the end of the product in accordance with the user requirements, without the user adjustment.
Tapered roller bearings have a conical inner ring and an outer race raceway, and tapered rollers are arranged between them. The projection lines of all conical surfaces are gathered at the same point of the bearing axis. This design makes tapered roller bearings particularly suitable for compound (radial and axial) loads. The axial load capacity of the bearing is mostly determined by the contact angle. The greater the angle, the higher the axial load capacity. The size of the angle is expressed by calculating the coefficient e. The greater the E value and the greater the contact angle, the greater the applicability of the bearing to axial load.
Tapered roller bearings are usually separated, that is, the conical inner ring components with the inner ring of the roller and the cage assembly can be installed separately from the conical outer ring (outer ring).
Tapered roller bearings are widely used in automobile, rolling mills, mines, metallurgy, plastics machinery and other industries.
