国标骨架油封型号及配套的轴和孔加工要求.pdf

骨架油封骨架油封 骨架油封的作用一般就是将传动部件中需要润滑的部件与出力部件隔离， 不至于让润滑油渗 漏，通常用于 旋转轴，是一种旋转轴唇密封。骨架就如同混凝土构件里面的钢筋，起到加强的作用，并使 油封能保持形状及张力。按骨架型式可分为内骨架油封，外骨架油封，内外露骨架油封。 骨 架油封是采用优质丁腈橡胶和钢板制作而成，质量稳定，使用寿命长。广泛用于汽车，摩托 车曲轴，凸轮轴，差速器，减震器，发动机，车桥，前后轮等部位。 平时应用时应： 1、防止泥沙、灰尘、水气等自外侵入轴承中； 2、限制轴承中的润滑油漏出。对油封的要求是尺寸（内径、外径和厚度）应符合规定； 要求有适当的弹性， 能将轴适当地卡住， 起到密封作用； 要耐热、 耐磨、 强度好、 耐介质（油 或水等） ，使用寿命长。 合理使用油封，应注意以下几点： (1)轴的转速由于设计和结构上的原因，高转数的轴应使用高速油封，低转速的轴使用 低速油封，不能将低速油封用于高速轴上，反之也不行。 (2)环境温度在使用温度较高的情况下，应选用聚丙烯酯或硅、氟、硅氟橡胶。并应设 法降低油箱中的油温。在使用温度过低的情况下，应选用耐寒橡胶。 (3)压力一般的油封承受压力能力差，压力过大时油封会变形。在压力过大的使用条件 下应采用耐压支承圈或加强的耐压油封。 (4)安装上的偏心程度油封和轴配合时偏心过大，则其密封性会变差，特别是在轴转速 高时尤为严重。如果偏心过大时，可采用“W”形断面的油封。 (5)轴的表面光洁度，直接影响油封的使用寿命，即轴的光洁度高，油封使用寿命就会 长。 (6)注意在油封的唇口应有一定量的润滑油。 (7)要特别注意防止尘土浸入油封。 一、与骨架油封配套的轴和孔要求一、与骨架油封配套的轴和孔要求 骨架油封是通用件和标准件，它与轴、孔用的弹性档圈一样，只要按轴或孔的公称直径尺寸 报规格就行了，骨架油封也是如此，反过来说已知骨架油封的内外径及高度的公称尺寸后， 就可按其公称尺寸+公差加工轴、座的实际尺寸。 基本要求： 1， 轴的材质 一般选用碳素钢，如不得不使用铸铁时，推荐使用球墨铸铁。 2， 轴表面加工硬度 通常线速度低于 4m/S 时，硬度为 45HRC，大于 4m/S 时，则硬度为 55HRC。 另外，轴的 最终加工痕迹也要尽可能的不呈螺纹状，避免与油封唇口共同产生泵送效应而影响密封性 能。 3， 轴的径向跳动 转速为 1500r/min 时，约允许 0。15 、转速为 30000r/min 时，约允许 0.10 。 4，油封座孔的内径公差及表面粗糙度应满足下表要求 部位公差内包骨架 （粗糙度）外包骨架（粗糙度） 座孔H8Ra=1.66.3mRa=0.83.2m 轴h11Ra=0.20.8m 注：表面粗糙度太小了也不理于唇口与轴之间的润滑液膜形成 5， 座孔与轴的同轴度应满足一下要求： 轴颈（mm）同轴度(mm) 200.1 400.15 600.20 801200.240.28 1302000.300.35 2205000.360.38 二、国标骨架油封型号二、国标骨架油封型号 序号规格序号规格序号规格序号规格
