Tapered roller bearing，Rodamiento de rodillos cónicos is a radial thrust type rolling bearing in which the rolling elements are tapered rollers. There are two kinds of small cone angle and large cone angle. The small cone angle mainly bears radial and axial combined loads mainly based on radial load. It is often used in double and reverse installation. The inner and outer races can be installed separately. The radial and axial clearance can be adjusted during installation and use. The large cone angle is mainly subjected to axial and radial combined loads mainly based on axial loads. Generally, it is not used alone to withstand pure axial loads. When paired configuration (relatively installed at the same name), it can be used to withstand pure radial loads.
Tapered roller bearings are separate bearings, and the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types such as single row, double row and four row tapered roller bearings according to the number of rows of rollers installed. Single row tapered roller bearings can withstand radial loads and axial loads in a single direction. When the bearing is subjected to a radial load, an axial component will be generated, so that another bearing that can withstand the axial force in the opposite direction is needed to balance.
Classification of tapered roller bearings
According to the number of rows of rolling elements in the bearing, it is divided into single row, double row and four row tapered roller bearings. The clearance of the single-row tapered roller bearing needs to be adjusted by the user during installation; the double-row and four-row tapered roller bearing clearance has been given according to the user's requirements at the time of shipment from the factory, and no user adjustment is required.
1> A single row tapered roller bearing has an outer ring, an inner ring assembly of the inner ring and a set of tapered rollers comprised of a basket-shaped cage. The outer ring can be separated from the inner ring assembly. According to the ISO tapered roller bearing external dimensions, any standard type of tapered roller bearing outer ring or inner ring assembly should be able to achieve internationality with the same type of outer ring or inner ring assembly. exchange. That is, the outer ring of the same model must meet the requirements of ISO492 (GB307) in addition to the external dimensions and tolerances. The taper angle of the inner ring assembly and the diameter of the component cone must also comply with the relevant provisions of the interchange.
Generally, the single-row tapered roller bearing outer ring raceway has a cone angle of 10° to 19°, and can simultaneously bear the combined effect of axial load and radial load. The larger the cone angle, the greater the ability to withstand axial loads. Large cone angle bearing, rear code plus B, cone angle between 25 ° ~ 29 °, it can withstand large axial loads. In addition, single row tapered roller bearings can adjust the clearance during installation.
2> The outer ring (or inner ring) of the double row tapered roller bearing is a whole. The two inner rings (or outer rings) have similar small end faces, and there are bearing spacers in the middle. The clearance is adjusted by the thickness of the spacers. The thickness of the spacers can also be used to adjust the pre-interference of the double-row tapered roller bearings.
3> Four-row tapered roller bearings, the performance of this type of bearing is basically the same as that of double-row tapered roller bearings, but the radial load is larger than that of double-row tapered roller bearings, and the limit speed is slightly lower, mainly used for heavy machinery. .
4>Multi-sealed double and four-row tapered roller bearings, long-life, multi-sealed double and four-row tapered roller bearings. Personalized new design of the bearing, changing the traditional design method of the fully sealed bearing, adopting a new sealing structure type combining sealing and dustproof, improving the sealing effect and improving the sealing performance. Multi-sealed double and four-row tapered roller bearings have a 20% to 40% increase in life compared to open-frame bearings; lubricant consumption is reduced by 80%.
