Taper Roller Bearings Widely Used In Plastics Machinery And Other Industries
- Nov 01, 2017 -

Tapered roller bearings are separate bearings, bearing inner and outer ring with a tapered raceway. This type of bearing according to the number of columns installed roller is divided into single row, double row and four row of tapered roller bearings and other different structural types. Single row tapered roller bearings can withstand radial loads and single direction axial loads. When the bearing under radial load, will produce an axial component, so when you need another bearing in the direction of the axial force to balance. Widely used in automobiles, rolling mills, mining, metallurgy, plastic machinery and other industries.

Tapered roller bearings are mainly subjected to radial-based radial and axial combined loads. Bearing bearing capacity depends on the outer raceway angle, the greater the angle the greater the carrying capacity. This type of bearing is a separate bearing, according to the number of rolling bearings in the bearing is divided into single row, double row and four row tapered roller bearings. Single row tapered roller bearing clearance to be installed at the time of adjustment; double row and four row of tapered roller bearing clearance has been in the product factory according to user requirements given, no user to adjust.

Tapered roller bearings have conical inner and outer ring raceways, tapered roller arrangement between the two. The projection lines of all conical surfaces converge at the same point on the bearing axis. This design makes tapered roller bearings particularly suitable for receiving composite (radial and axial) loads. The axial load capacity of the bearing is mostly determined by the contact angle α; the larger the α angle, the higher the axial load capacity. The angle size is expressed by the calculation factor e; the greater the e value, the greater the contact angle, the greater the applicability of the bearing to the axial load.

Tapered roller bearings are usually separable, that is, by the roller with the cage assembly of the inner ring of the conical inner ring assembly can be installed with the conical outer ring (outer ring).

Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.

Tapered roller bearings are mainly used to bear the radial load-based radial and axial joint load. Compared with angular contact ball bearings, bearing capacity, low speed limit. Tapered roller bearings are capable of withstanding axial loads in one direction, limiting axial displacement of the shaft or housing in one direction.
