Tapered roller bearings mainly bear radial and axial combined loads. Tapered roller bearings are widely used in automobiles, rolling mills, mining, metallurgy, plastic machinery and other industries. The analysis of the classification of lower tapered roller bearings for Beiren bearings.
The single-row tapered roller bearing has an outer ring, an inner ring and a set of tapered rollers, an inner ring assembly formed by a basket-shaped cage. The outer ring can be separated from the inner ring component. According to the ISO standard for external dimensions of tapered roller bearings, the outer ring or inner ring component of any standard tapered roller bearing should be able to achieve internationality with the outer ring or inner ring component of the same model. exchange. That is to say, in addition to the outer dimensions and tolerances of the same type of outer ring must meet the requirements of ISO492 (GB307), the cone angle of the inner ring component, the diameter of the component cone, etc. must also meet the relevant regulations of interchange.
Generally, the tapered angle of the outer ring raceway of a single-row tapered roller bearing is between 10 ° and 19 °, which can simultaneously bear the combined action of axial load and radial load. The larger the cone angle, the greater the ability to withstand axial loads. Bearings with a large tapered angle, with a post code plus B, with a tapered angle between 25 ° and 29 °, can withstand large axial loads. In addition, the single-row tapered roller bearing can adjust the clearance during the installation process.
The outer ring (or inner ring) of a double-row tapered roller bearing is a whole. The two small inner end faces of the inner ring (or outer ring) are similar, with 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 the double-row tapered roller bearing.
Four-row tapered roller bearings, the performance of this bearing is basically the same as double-row tapered roller bearings, but the radial load is greater than double-row tapered roller bearings, the limit speed is slightly lower, mainly used in heavy machinery.
Multi-sealed double and four-row tapered roller bearings, ZWZ provides long-life, multi-sealed double and four-row tapered roller bearings. The bearing is individually and completely new designed, the traditional design method of the fully sealed bearing is changed, and a new type of sealing structure combining sealing and dustproof is adopted to improve the sealing effect and sealing performance. Compared with open structure bearings, multi-sealed double-row and four-row tapered roller bearings have a 20% to 40% longer life and a 80% reduction in lubricant consumption.
