A rolling bearing, the main types, properties and characteristics

按滾動(dòng)體的形狀，滾動(dòng)軸承可分為球軸承和滾子軸承。

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

按接觸角 的大小和所能承受載荷的方向，軸承可分為：

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

1、向心軸承：

1, the radial bearing:

公稱接觸角：0° 45°，向心軸承又可細(xì)分為：

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

A、徑向接觸軸承： ＝0°，只能承受徑向載荷(如圓柱滾子軸承)，或主要用于承受徑向載荷，但也能承受少量的軸向載荷(如深溝球軸承)；

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、向心角接觸軸承：0°< 45°，能同時(shí)承受徑向載荷和單向的軸向載荷(如角接觸球軸承及圓錐滾子軸承)。

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、推力軸承：

2, the thrust bearing:

公稱接觸角：45°< 90°，推力軸承又可細(xì)分為：

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

A、軸向接觸軸承： ＝90°，只用于承受軸向載荷；

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

B、推力角接觸軸承：45°< <90°主要承受大的軸向載荷，也能承受不大的徑向載荷。

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

按自動(dòng)調(diào)心性能，軸承可分為自動(dòng)調(diào)心軸承和非自動(dòng)調(diào)心軸承。

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

滾子軸承的類型很多，現(xiàn)將最常用的幾種滾動(dòng)軸承的性能和特點(diǎn)作一簡要介紹，其他的見表9-1中

Many types of roller bearing, the most common properties and characteristics of the rolling bearing are briefly introduced, the other table in 9-1
