Tapered roller bearings are mainly used to bear combined radial and axial loads, mainly radial loads, and are generally not suitable for bearing axial loads alone. This type of bearing is designed so that the vertices of the conical surfaces of the inner ring raceway surface, outer ring raceway surface and roller rolling surface intersect at a point on the center line of the bearing. In addition to the metric series products, there are also a variety of imperial series products. Suitable for heavy loads and shock loads. In addition to single-row bearings, tapered roller bearings also have double-row bearings, paired double-link bearings and four-row bearings. Tapered roller bearing cages generally use stamping cages.
A car usually has about 30 kinds of 50 sets of bearings installed in different rotating parts. In practice, automotive bearings are generally classified according to their installation or use position. Corresponding to the division of automobiles into engines, transmission systems, steering systems and air-conditioning systems, automotive bearings can be firstly divided into engine bearings, transmission system bearings, steering system bearings and air conditioner bearings according to the installation position, and then can be further subdivided into The various components of the above system and even the specific installation position of the bearing. Due to the diversification of automobile and bearing designs, similar parts of different automobiles often adopt different component structures and bearing structures. The installation position diagram of the bearing and the corresponding bearing type spectrum can be used to express the installation position of the bearing in more detail and intuitively, and the internal relationship between the components and the bearing can be revealed by giving the bearing model, external dimension and its installation position at the same time.
With the development of automobile technology, the design, manufacture, test and application technology of automobile bearings have made great progress. However, from the perspective of application, the development of automobile bearings can be summarized as the expansion of general-purpose bearings, the development of special bearings, and the improvement of bearing performance and life.
1) Expanded application of general bearings
The improvement of automobile structure, the development of varieties and specifications, the improvement of performance and life, and the diversification of automobile design and bearing design have led to the expansion of the application range of general bearings.
So far, general-purpose bearings directly applied in automobiles have covered almost all basic structure types, more and more series and more and more specifications of general-purpose bearings, and the improvement and development of direct-applied general-purpose bearings have led to the emergence of Some new general bearing series and special bearings.
2) Development of special bearings
Some automotive special bearings gradually developed on the basis of general-purpose bearings have structural and functional features that are not found in traditional rolling bearings and are closely related to automotive applications. Among these special bearings for automobiles, the expansion of the structure and function of hub bearings and clutch release bearings is the most eye-catching.
