How to calculate the nominal width of tapered roller bearings?
The ability of single row tapered roller bearings to bear axial load depends on the contact angle, that is, the angle of the outer raceway, the greater the angle, the greater the axial load capacity. The single roller tapered roller bearings are the most used in tapered roller bearings. In the front wheel hub of a car, a small, double row tapered roller bearing is used. Four row tapered roller bearings are used in heavy, cold and hot rolling mills and other heavy machines. Structural features, tapered roller bearings of type 30000 code, tapered roller bearings for the separation of bearings. Under normal circumstances, especially in the size range GB/T307.1-94 "rolling bearing radial bearing tolerances" involved in the tapered roller bearing outer ring and inner components are interchangeable with one hundred percent. The angle of the outer race and the diameter of the outer raceway are the same as the dimensions and are standardized. Changes are not allowed during design and manufacture. Therefore, the outer ring and the inner component of the tapered roller bearing can be interchanged and interchangeable all over the world. Tapered roller bearings are mainly used to bear radial load combined radial and axial load. Compared with angular contact ball bearing, the bearing capacity is large and the limit speed is low. Tapered roller bearings can withstand axial loads in one direction and can limit axial displacements in one direction of the shaft or shell.
The classification of single row tapered roller bearing has an outer ring, the inner ring and a conical roller by maintaining a basket frame into the inner module. Outer and inner components can be separated in accordance with the provisions of ISO tapered roller bearings standard, a standard model of tapered roller bearing outer ring or inner components should be able to model the outer or inner component to achieve an international exchange. That is, the outer ring of the same type, except for the external size and tolerances, shall comply with the requirements of ISO492 (GB307), the cone angle of the inner ring component and the diameter of the component cone must also comply with the relevant provisions of the exchange. Generally, the taper angle of the outer raceway of single row tapered roller bearings is between 10 and ~19 degrees, and it can bear the combined action of axial load and radial load simultaneously. The greater the cone angle, the greater the ability to bear axial load. Large cone angle bearings, rear code plus B, cone angle between 25 degrees ~29 degrees, it can withstand greater axial load. In addition, single row tapered roller bearings can adjust the clearance size during installation. The outer ring (or inner ring) of a double row tapered roller bearing is a whole.
