1、角接触球轴承安装尺寸一、角接触球轴承的安装:角接触球轴承安装应根据轴承结构,尺寸大小和轴承部件的配合性质而定,压力应直接加在紧配合得套圈端面上,不得通过滚动体传递压力。角接触球轴承安装的方法:一般情况下是轴旋转的情况居多,因此内圈与轴的配合为过赢配合,轴承外圈与轴承室的配合为间隙配合。安装时注意事项: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角接触球轴承端面,以免损伤轴承。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
2、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角接触球轴承方法来安装,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。角接触球轴承安装最后汇普轴承建议: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。二、角接触球轴承具体安装时的安装尺寸如下:基本尺寸安装尺寸基本额定载荷极限转速重量轴承代号dDBadsminDamaxrasmaxCrCor脂油W≈7
