圆锥滚子轴承的安装

日期:2019-06-18 07:20 作者:ina 阅读:

  一、轴承的安装: 
  轴承的安装必须在干燥、清洁的环境条件下进行。安装前应仔细检查轴和外壳的配合表面、凸肩的端面、沟槽和连接表面的加工质量。所有配合连接的表面,必须仔细清洗并除去毛刺,铸件未加工表面必须除净残留的型砂。 
  轴承安装前应先用汽油或煤油清洗干净,干燥后使用,并保证良好润滑,轴承一般采用润滑脂,也可采用油润滑。ina导轨金属或其它材料制成的槽或脊,可承受、固定、引导移动装置或设备并减少其摩擦的一种装置。导轨表面上的纵向槽或脊,用于导引、固定机器部件、专用设备、仪器等。采用脂润滑时,应选用无杂质、抗氧化、防锈、极压等性能优质的润滑脂。润滑脂填充量为轴承及轴承箱容积的30%-60%,不宜过多。带密封结构的双列圆锥滚子轴承和水泵轴连轴承已填充好润滑脂,用户可直接使用,不可再进行清洗。 
  轴承安装时,必须在套圈端面的圆周上施加均等的压力,将套圈压入,不得用鎯头等工具直接敲击轴承端面,以免损伤轴承。ina轴承是当代机械设备中一种重要零部件。它的主要功能是支撑机械旋转体,降低其运动过程中的摩擦系数,并保证其回转精度。在过盈量较小的情况下,可在常温下用套筒压住轴承套圈端面,用鎯头敲打套筒,通过套筒将套圈均衡地压入。如果大批量安装时,可采用液压机。压入时,应保证外圈端面与外壳台肩端面,内圈端面与轴台肩端面压紧,不允许有间隙。 
  当过盈量较大时,可采用油浴加热或感应器加热轴承方法来安装,加热温度范围为80℃-100℃,最高不能超过120℃。同时,应用螺母或其它适当的方法紧固轴承,以防止轴承冷却后宽度方向收缩而使套圈与轴肩之间产生间隙。 
  单列圆锥滚子轴承安装最后应进行游隙的调整。游隙值应根据不同的使用工况和配合的过盈量大小而具体确定。必要时,应进行试验确定。双列圆锥滚子轴承和水泵轴连轴承在出厂时已调整好游隙,安装时不必再调整。 
  轴承安装后应进行旋转试验,首先用手旋转轴或轴承箱,若无异常,便以动力进行无负荷、低速运转,然后视运转情况逐步提高旋转速度及负荷,并检测噪音、振动及温升,发现异常,应停止运转并检查。运转试验正常后方可交付使用。 
  二、轴承的拆卸: 
  轴承拆下后拟继续使用时,应选用适当的拆卸工具。拆卸过盈配合的内套圈,只能将拉力加在该套圈上,绝不允许通过滚动体(外圈)传递拆卸力,否则滚动体和滚道都会被压伤。 
  三、轴承的使用环境: 
  根据使用部位及使用条件与环境条件选择规格尺寸、精度,配合适宜的轴承是保证轴承寿命及可靠性的前提。 
  1、使用部位:圆锥滚子轴承适用于承受以径向载荷为主的径向与轴向的联合负荷,通常以两套轴承配对使用,主要应用于汽车的前后轮毂、主动圆锥齿轮、差速器、减速器等传动部位。 
  2、允许转速:在安装正确、润滑良好的环境下,允许为轴承极限转速的0.3-0.5倍。一般正常情况下,以0.2倍的极限转速为最宜。 
  3、允许倾斜角:圆锥滚子轴承一般不允许轴相对外壳孔有倾斜,如有倾斜,最大不超过2′。 
  4、允许温度:在承受正常的载荷,且润滑剂具有耐高温性能,且润滑充分的条件下,一般轴承允许在-30℃---150℃的环境温度下工作。ina滑块是在模具的开模动作中能够按垂直于开合模方向或与开合模方向成一定角度滑动的模具组件。 当产品结构使得模具在不采用滑块不能正常脱模的情况下就得使用滑块了。序号 轴承型号
