A rolling bearing, the main types, properties and characteristics

按滚动体的形状，滚动轴承可分为球轴承和滚子轴承。

According to the shape of the rolling body, can be divided into the ball bearings and roller bearings rolling bearings.

按接触角 的大小和所能承受载荷的方向，轴承可分为：

According to the contact angle and can bear load direction, bearings can be divided into:

1、向心轴承：

1, the radial bearing:

公称接触角：0° 45°，向心轴承又可细分为：

Nominal contact angle: 0 degrees 45 degrees, radial bearings can be subdivided into:

A、径向接触轴承： ＝0°，只能承受径向载荷(如圆柱滚子轴承)，或主要用于承受径向载荷，但也能承受少量的轴向载荷(如深沟球轴承)；

A, radial contact ball bearing: = 0 DEG, can bear radial load (such as cylindrical roller bearings), or are mainly used to bear radial load, but also can withstand the axial load (such as a small amount of deep groove ball bearing);

B、向心角接触轴承：0°< 45°，能同时承受径向载荷和单向的轴向载荷(如角接触球轴承及圆锥滚子轴承)。

B, angular contact radial bearing: 0 degree < 45 degrees, and can bear radial load and axial load (such as one-way angular contact ball bearings and tapered roller bearings).

2、推力轴承：

2, the thrust bearing:

公称接触角：45°< 90°，推力轴承又可细分为：

Nominal contact angle: 45 degree < 90 degrees, thrust bearings can be subdivided into:

A、轴向接触轴承： ＝90°，只用于承受轴向载荷；

A, the axial contact bearing: = 90 DEG, only to bear axial load;

B、推力角接触轴承：45°< <90°主要承受大的轴向载荷，也能承受不大的径向载荷。

B, angular contact thrust bearing 45 degrees <90 degrees: < mainly bear large axial load, radial load also can bear big.

按自动调心性能，轴承可分为自动调心轴承和非自动调心轴承。

According to the performance of automatic regulation, the bearing can be divided into automatic self-aligning bearing and non self-aligning bearing.

滚子轴承的类型很多，现将最常用的几种滚动轴承的性能和特点作一简要介绍，其他的见表9-1中
