style="text-indent:2em;"> 机器或设备日常检修或发生损坏时都会需要拆轴承,特别是由于轴承故障而拆卸时,检查轴承周围零件、润滑剂和轴承本身的情况,这有助于找出故障原因和需要改进的区域、解决问题。那么如何正确拆卸轴承呢?有哪些拆卸方法?又该如何选择工具呢?今天我们就跟大家分享一篇干货?</p> <p style="text-indent:2em;"> 如何进行轴承的拆卸? </p> <p style="text-indent:2em;"> 1、最好在经验丰富的人员或在其指导下进行?</p> <p style="text-indent:2em;"> 2、拆卸开始前,确定要拆卸的具体方法?</p> <p style="text-indent:2em;"> 3、手边备好必要的轴承拆卸工具?</p> <p style="text-indent:2em;"> 4、重新使用或者检查已拆卸轴承时,注意避免划伤或者损害轴承滚道或滚动体;从轴承座上拆卸轴承时,拆卸力加于外圈;从轴上拆卸轴承,拆卸力加于内圈?</p> <p style="text-indent:2em;"> 拆卸轴承的主要方法? </p> <p style="text-indent:2em;"> 1、使用手或者液?</p> <p style="text-indent:2em;"> 2、只用专用扳?</p> <p style="text-indent:2em;"> 3、使用拔?</p> <p style="text-indent:2em;"> 4、使用感应加热设备(内圈?</p> <p style="text-indent:2em;"> 5、使用注油法 </p> <p style="text-indent:2em;"> 如何选定不同的工具? </p> <p style="text-indent:2em;"> 冷拆?</p> <p style="text-indent:2em;"> 拆卸较小型轴承时,可通过合适的冲头,轻轻敲击轴承套圈的侧面以将其从轴上卸下,更佳的方法是使用机械拉拔器。拉抓应作用于内圈或相邻部件。如果轴肩和轴承座孔肩预留了可容纳拉拔器拉抓的凹槽,则可以简化拆卸过程。此外,在孔肩的位置加工一些螺纹孔,便于螺栓把轴承顶出?</p> <p style="text-indent:2em;"> 大中型轴承所需的力通常要比机械工具所能提供的更大。因此,建议使用液压助力工具或注油法,或两者一起使用。这意味着需要在轴上设计有油孔和油槽?</p> <p style="text-indent:2em;"> 热拆?</p> <p style="text-indent:2em;"> 拆卸滚针轴承或NU、NJ、和NUP型圆柱滚子轴承的内圈时,适合使用热拆卸方法。常用的两种加热工具:加热环和可调式感应加热器?</p> <p style="text-indent:2em;"> 加热环通常用于安装和拆卸与其尺寸相同的中小型轴承的内圈。加热环由轻合金制成。加热环带有径向开槽,且配备电绝缘手柄?</p> <p style="text-indent:2em;"> 如果经常拆卸不同直径的内圈,建议使用可调试感应加热器。这些加热器可以迅速加热内圈,而不会使轴变热。拆卸大型的圆柱滚子轴承的内圈时,可以使用一些特殊的固定式感应加热器?</p> <p style="text-indent:2em;"> 拆卸安装在圆锥形轴径上的轴承 </p> <p style="text-indent:2em;"> 可使用机械或液压助力拉拔器拉住内圈,即可拆卸小型轴承。某些拉拔器配有弹簧操作臂,使用这种有自对芯设计的拉拔器,可以简化程序,避免损坏轴颈。倘若不能在内圈上使用拉拔器拉爪,则应经由外圈,或采用拉拔器结合拉拔片的方式拆卸轴承?</p> <p style="text-indent:2em;"> 使用注油法时,中大型轴承的拆卸会更加安全简单。这种方法在高压下通过油孔和油槽将液压油注入两个圆锥形配合面之间。两个表面之间的摩擦大幅减少,并产生使轴承和轴径分开的轴向力?</p> <p style="text-indent:2em;"> 拆卸紧定套上的轴?</p> <p style="text-indent:2em;"> 对安装在紧定套配直身轴上的小型轴承,可以使用锤子来敲击均匀作用在轴承内圈端面的小钢块来拆卸。在此之前,需要将紧定套锁紧螺母拧松数圈?</p> <p style="text-indent:2em;"> 对安装于紧定套配阶梯轴上的小型轴承,可以使用锤子通过一个特制的套筒敲击紧定套锁紧螺母的小端面来拆卸。在此之前,需要将紧定套锁紧螺母拧松数圈?</p> <p style="text-indent:2em;"> 对于安装在紧定套配阶梯轴上的轴承,使用液压螺母可使轴承拆卸更简便。为此必须在紧靠液压螺母活塞的位置安装合适的止动装置,注油法是更简易的方法,但必须使用带有油孔和油槽的紧定套?</p> <p style="text-indent:2em;"> 拆卸退卸套上的轴承 </p> <p style="text-indent:2em;"> 拆卸退卸套上的轴承时,必须卸下锁定装置。(如锁紧螺母,端板等) </p> <p style="text-indent:2em;"> 对于中小型的轴承,可以利用锁紧螺母、钩形扳手或冲击扳手来进行拆卸?</p> <p style="text-indent:2em;"> 对于安装在退卸套上的中大型轴承,可以利用液压螺母轻松拆卸。建议在轴端的液压螺母后面安装止动装置。该止动装置可以防止退卸套从配合位置突然分离时,退卸套和液压螺母从轴上飞出来?</p> <p style="text-indent:2em;"> 这些要点要注?</p> <p style="text-indent:2em;"> 1、务必检查拆卸工作前是否有裂纹、锐源、断裂、碎片或变形?</p> <p style="text-indent:2em;"> 2、使用压具时,所有部件平稳,不摇晃或者颤动;压动轴时,轴的中心必须与锤子的中心对齐;用力时切勿手抓住轴;放置一个接盘接住轴或者轴承,以免掉落在地?</p> <p style="text-indent:2em;"> 3、使用拔具时,确认拔具的卡爪卡牢轴承的侧面;将拔具上负荷螺栓的末端对准轴;如果卡爪在操作过程中变松,则立即停止,换个位置卡牢后,恢复操作;如施加正常的拆卸力后,轴承未能脱出,请勿对拔具过度施力,改用其他方法?</p> <p style="text-indent:2em;"> 4、使用专业扳手(拆卸套筒)时,请用大小合适的锁紧螺母的扳手;如果锁紧螺母过紧,请勿用锤子敲击扳手的柄?</p> <p style="text-indent:2em;"> 5、使用轴承注油法的时候,慢慢地注入油,当内圈沿轴向移动时,立即停止注油;锥孔轴承可能会高速飞离轴承,务必在轴的末端安装一个螺母,以防止其飞离?</p> <p style="text-indent:2em;"> 6、使用感应加热设备时,切勿在工作区域附近放置易燃材料(如油或燃气);重复使用轴承或需要进行检查时,切勿加热超?20℃;切勿不带手套触摸加热后的轴承或周围零件;加热完毕,立即从轴上拆下轴承(内圈);如果早拆卸时,轴承内圈难以移动,停止操作,重新加热轴承(内圈),再继续操作?</p></div><div class="meneame"><span class="disabled"><
