滚动轴承的分类
1.按滚动轴承结构类型分类
(1)轴承按其所能承受的载荷方向或公称接触角的不同,分为:
1)向心轴承----主要用于承受径向载荷的滚动轴承,其公称接触角从0到45。按公称接触角不同,又分为:径向接触轴承----公称接触角为0的向心轴承:向心角接触轴承----公称接触角大于0到45的向心轴承。
2)推力轴承----主要用于承受轴向载荷的滚动轴承,其公称接触角大于45到90。按公称接触角不同又分为:轴向接触轴承----公称接触角为90的推力轴承:推力角接触轴承----公称接触角大于45但小于90的推力轴承。
(2)轴承按其滚动体的种类,分为:
1)球轴承----滚动体为球:
2)滚子轴承----滚动体为滚子。滚子轴承按滚子种类,又分为:圆柱滚子轴承----滚动体是圆柱滚子的轴承,圆柱滚子的长度与直径之比小于或等于3;滚针轴承----滚动体是滚针的轴承,滚针的长度与直径之比大于3,但直径小于或等于5mm;圆锥滚子轴承----滚动体是圆锥滚子的轴承;调心滚子轴承一一滚动体是球面滚子的轴承。
(3)轴承按其工作时能否调心,分为:
1)调心轴承----滚道是球面形的,能适应两滚道轴心线间的角偏差及角运动的轴承;
2)非调心轴承(刚性轴承)----能阻抗滚道间轴心线角偏移的轴承。
(4)轴承按滚动体的列数,分为:
1)单列轴承----具有一列滚动体的轴承;
2)双列轴承----具有两列滚动体的轴承;
3)多列轴承----具有多于两列滚动体的轴承,如三列、四列轴承。
(5)轴承按其部件能否分离,分为:
1)可分离轴承----具有可分离部件的轴承;
2)不可分离轴承----轴承在最终配套后,套圈均不能任意自由分离的轴承。
(6)轴承按其结构形状(如有无装填槽,有无内、外圈以及套圈的形状,挡边的结构,甚至有无保持架等)还可以分为多种结构类型。
2.按滚动轴承尺寸大小分类轴承按其外径尺寸大小,分为:
(1)微型轴承----公称外径尺寸范围为26mm以下的轴承;
(2)小型轴承----公称外径尺寸范围为28-55mm的轴承;
(3)中小型轴承----公称外径尺寸范围为60-115mm的轴承;
(4)中大型轴承----公称外径尺寸范围为120-190mm的轴承
(5)大型轴承----公称外径尺寸范围为200-430mm的轴承;
(6)特大型轴承----公称外径尺寸范围为440mm以上的轴承。
滚动轴承的基本生产过程
由于滚动轴承的类型、结构型式、公差等级、技术要求、材料及批量等的不同,其基本生产过程也不完全相同。
一、各种轴承主要零件的加工过程:
1.套圈的加工过程:轴承内圈和外圈的加工依原材料或毛坯形式的不同而有所不同,其中车加工前的工序可分为下述三种,整个加工过程为:棒料或管料(有的棒料需经锻造和退火、正火)----车加工----热处理----磨加工----精研或抛光----零件终检----防锈----入库----(待合套装配〉
2.钢球的加工过程,钢球的加工同样依原材料的状态不同而有所不同,其中挫削或光球前的工序,可分为下述三种,热处理前的工序,又可分为下述二种,整个加工过程为:棒料或线材冷冲(有的棒料冷冲后还需冲环带和退火)----挫削、粗磨、软磨或光球----热处理----硬磨----精磨----精研或研磨----终检分组----防锈、包装----入库〈待合套装配〉。
3.滚子的加工过程滚子的加工依原材料的不同而有所不同,其中热处理前的工序可分为下述两种,整个加工过程为:棒料车加工或线材冷镦后串环带及软磨----热处理----串软点----粗磨外径----粗磨端面----终磨端面----细磨外径----终磨外径----终检分组----防锈、包装----入库(待合套装配〉。
4.保持架的加工过程保持架的加工过程依设计结构及原材料的不同,可分为下述两类:
(1)板料→剪切→冲裁→冲压成形→整形及精加工→酸洗或喷丸或串光→终检→防锈、包装→入库(待合套装配)
(2)实体保持架的加工过程:实体保持架的加工,依原材料或毛坏的不同而有所不同,其中车加工前可分为下述四种毛坯型式,整个加工过程为:棒料、管料、锻件、铸件----车内径、外径、端面、倒角----钻孔(或拉孔、镗孔)----酸洗----终检----防锈、包装----入库〈待合套装配〉。
