Tapered roller bearings are separated type bearings. Both inner and outer rings of the bearings have tapered raceways, and the roller is round. The roller is in line contact with the raceway and can bear heavy combined radial and axial loads as well as pure axial loads. The larger the contact angle, the higher the axial bearing capacity.
圓錐滾子軸承的特點（Characteristics of tapered roller bearings）
圓錐滾子的設(shè)計應(yīng)使?jié)L子與內(nèi)外滾道的接觸線延長后交于軸承軸線上同一點，以實現(xiàn)純滾動。
The tapered roller should be designed so that the contact line between the roller and the inner and outer raceways is extended and intersected at the same point on the axis of the bearing to achieve pure rolling.
新設(shè)計的圓錐滾子軸承采用加強型結(jié)構(gòu)，滾子直徑加大，滾子長度加長，滾子數(shù)目增多，采用帶凸度滾子，使軸承的承載能力和疲勞壽命顯著提高。 滾子大端面與大擋邊之間采用球面與錐面接觸，改善了潤滑。
The newly designed tapered roller bearing adopts the reinforced structure, the roller diameter increases, the roller length lengthens, the number of rollers increases, and the roller with crown is adopted, so that the bearing bearing capacity and fatigue life are significantly improved. The contact between the large surface of the roller and the big edge is spherical and conical, which improves lubrication.
該類軸承按所裝滾子的列數(shù)可分為單列、雙列和四列圓錐滾子軸承等不同的結(jié)構(gòu)型式。該類軸承還多使用英制系列產(chǎn)品。
This kind of bearing can be divided into single row, double row and four row tapered roller bearings according to the number of rows installed. This type of bearings also use more British series products.
圓錐滾子軸承的結(jié)構(gòu)特點（Structural characteristics of tapered roller bearings）
圓錐滾子軸承的類型代號為30000，圓錐滾子軸承為分離型軸承。一般情況下，尤其是在GB/T307.1-94《滾動軸承向心軸承公差》中所涉及到的尺寸范圍內(nèi)的圓錐滾子軸承外圈與內(nèi)組件之間是百分之百可以通用互換使用的。外圈的角度以及外滾道直徑尺寸已與外形尺寸相同被標準化規(guī)定了，不允許在設(shè)計制造時更改。以致使圓錐滾子軸承的外圈與內(nèi)組件之間可在世界范圍內(nèi)通用互換。
The type of tapered roller bearings is 30000, tapered roller bearings are separable bearings. In general, especially in GB / T307.1-94 "Rolling Bearing Centroid Bearing Tolerance" refers to the size range of tapered roller bearings between the outer ring and the inner assembly is 100% interchangeable. The angle of the outer ring and the diameter of the outer raceway have been standardized to the same size as the outer raceway. It is not allowed to be changed during design and manufacture. The outer ring and inner components of the tapered roller bearing can be exchanged all over the world.
圓錐滾子軸承主要用于承受以徑向載荷為主的徑向與軸向聯(lián)合載荷，與角接觸球軸承相比、承載能力大，極限轉(zhuǎn)速低。圓錐滾子軸承能夠承受一個方向的軸向載荷，能夠限制軸或外殼一個方向的軸向位移。
Tapered roller bearings are mainly used to withstand combined radial and axial loads with radial loads. Compared with angular contact ball bearings, tapered roller bearings have higher bearing capacity and lower limit speed. Tapered roller bearings can withstand axial loads in one direction and can limit axial displacement in one direction of the shaft or housing.
