1、推力圆锥滚子轴承的结构、性能特点

1, the structure and performance characteristics of thrust tapered roller bearings

由于推力圆锥滚子轴承中的滚动体为圆锥滚子，在结构上由于滚动母线与垫圈的滚道母线均汇交于轴承的轴心线上某一点，因而滚动表面可形成纯滚动、极限转速高于推力圆柱滚子轴承。

Due to the rolling thrust tapered roller bearings for tapered roller, in the structure due to raceway washer and bus rolling generatrix are crossed on the bearing axis of a point, so the rolling surface can form pure rolling, the speed limit is higher than the cylindrical roller thrust bearing.

推力圆锥滚子轴承可承受单向的轴向载荷。

Thrust tapered roller bearings can bear one-way axial load.

推力圆锥滚子轴承的类型代号为90000型。

The type of thrust tapered roller bearing code type 90000.

由于推力圆锥滚子轴承的生产量少，各厂已生产的型号多为非标准外形尺寸，而标准外形尺寸的系列，品种生产较少，因而目前尚无该类轴承的外形尺寸国家标准出台。

Because the production of tapered roller thrust bearing, the factory has produced models for non standard size, while the standard size of the series, so there is no less variety production, this kind of bearing national standard size introduction.

2、推力角接触球轴承的结构、性能特点

2, thrust angle contact ball bearing structure, performance characteristics

推力角接触球轴承接触角一般为60°常用的推力角接触球轴承一般为双向推力角接触球轴承，主要用于精密机床主轴，一般与双列圆柱滚子轴承一起配合使用，可承受双向轴向载荷，具有精度高，刚性好，温升低，转速高，装拆方便等优点。

Angular contact thrust ball bearing contact angle is 60 degrees common thrust angular contact ball bearing is generally two-way thrust angular contact ball bearings, mainly used for precision machine tool spindle, general combining with double row cylindrical roller bearings, can withstand two-way axial load, with high precision, good rigidity, low temperature, high speed, advantages convenient assembly and disassembly etc..

3、双列圆锥滚子轴承的结构、性能特点

3, double row tapered roller bearing structure, performance characteristics

双列圆锥滚子轴承结构繁多，最大量的是35000型，有一个双滚道外圈和两个内圈，两内圈之间有一隔圈，改变隔圈的厚度可调整游隙。这类轴承在承受径向载荷的同时可承受双向轴向载荷，可在轴承的轴向游隙范围内限制轴和外壳的轴向位移。

Double row tapered roller bearings of various structures, the largest number is type 35000, there is a double raceway outer ring and two inner ring, the two inner ring has a ring, change the thickness of the ring, adjustable clearance. This kind of bearing can bear both radial load and bi-directional axial load, and it can restrict axial displacement of shaft and shell in the axial clearance of bearing.
