Definition of tapered roller bearing

tapered roller bearings can be separated, and components and outer rings composed of inner rings, rollers and cages can be installed separately. The modified contact line at the contact between the roller and the raceway can reduce the stress concentration. Tapered roller bearings can withstand large radial and axial loads. Because the tapered roller bearing can only transmit one-way axial load, in order to transmit the axial load in the opposite direction, another tapered roller bearing installed symmetrically with it is required

single row tapered roller bearings are the most used tapered roller bearings. In the front wheel hubs of cars, but because asbestos is carcinogenic, small-size double row tapered roller bearings have also been used in recent years. Four row tapered roller according to gb/t528-1998 {determination of tensile stress-strain properties of vulcanized rubber or thermoplastic rubber "; elongation at break is the bearing converted by the tensile strength of the instrument measuring the tensile strength, which is used in large-scale cold and hot rolling mills and other heavy machines.

single row tapered roller bearings have an outer ring, and its inner ring and a group of tapered rollers are wrapped into an inner ring assembly by a basket cage. The outer ring can be separated from the inner ring assembly, according to ISO tapered roller According to the provisions of the bearing outline dimension standard, the outer ring or inner ring assembly of any standard model tapered roller bearing should be internationally interchangeable with the outer ring or inner ring assembly of the same model. That is, for the outer ring of the same model, except that the external dimension and tolerance must comply with the provisions of iso492 (gb307), the cone angle and cone diameter of the inner ring assembly must also comply with the relevant provisions of interchangeability

generally, we have developed a special fixture for all such transmissions for the outer ring of single row tapered roller bearings. The taper angle of the raceway is before 10 ° ~19 °, which can bear the combined action of bearing axial load and radial load at the same time. The larger the cone angle, the greater the ability to bear axial load. For bearings with large cone angle, post code plus B, the cone angle is between 25 ° ~29 °, and it can bear large axial load. In addition, the clearance of single row tapered roller bearings can be adjusted during installation

the outer ring (or inner ring) of double row tapered roller bearings is a whole. The small end faces of the two inner rings (or outer rings) are similar, and there is a spacer in the middle. The clearance is adjusted by the thickness of the spacer. The thickness of the spacer can also be used to adjust the pre interference of double row tapered roller bearings

tapered roller bearings mainly bear radial and axial combined loads. The bearing capacity depends on the raceway angle of the outer ring. The larger the angle is, the greater the bearing capacity is. This kind of bearing is a separate bearing, which is divided into single row, double row and four row tapered roller bearings according to the number of rows of rolling elements in the bearing. The clearance of single row tapered roller bearing needs to be adjusted by the user during installation; The clearance of double row and four row tapered roller bearings has been given according to the user's requirements when the product leaves the factory, and it does not need to be adjusted by the user

tapered roller bearings have conical inner ring and outer ring raceways, and tapered rollers are arranged between them. The projection lines of all conical surfaces converge at the same point of the bearing axis. This design makes tapered roller bearings particularly suitable for composite (radial and axial) loads. The axial load capacity of bearings is mostly determined by the contact angle α Determined; α The larger the angle, the higher the axial load capacity. The angle is expressed by the calculation coefficient E; The larger the E value is, the greater the contact angle is, and the greater the applicability of the bearing to bear axial load is

tapered roller bearings are usually of separate type, that is, the tapered inner ring assembly composed of the inner ring with roller and cage assembly can be installed separately from the tapered outer ring (outer ring)

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