轴承安装注意事项 Considerations for bearing installation 　　此节没有详细介绍轴承的安装步骤，只是重点讨论安装过程中需要额外注意的操作细节： This section does not detail the installation steps of the bearings, but focuses on the operational details that require extra attention during the installation process: 　　1.轴承下内圈装入轴座并回到室温时，需要用0.025mm的塞尺检查内圈与挡肩之间的间隙，确保已经安装到位;外圈亦是如此，如果没有到位，则用中等硬度的钢棒敲击端面，使其到位，以避免内外圈由于安装不到位而发生偏心，损伤轴承。 When the inner circle of the bearing is placed in the shaft and goes back to room temperature, it is necessary to check the clearance between the inner circle and the shoulder length of the inner circle with the 0.025mm plug, and ensure that the installation is in place. Outer ring is also so, if you are not in place, with medium hardness steel tap end face, make it reach the designated position, to avoid the inside and outside the circle due to installation does not reach the designated position eccentric, damage to the bearings. 　　2.完成轴承下内圈、外圈及滚子的安装后，调整齿圈端面与主轴端面的平行度(图中红线所示平面)，使下内圈与外圈平行;完成上内圈的安装后，正反转动轴承，使滚子和隔片正确定位，再调整齿圈端面与上内圈端面的平行度，最终确保三只轴承圈均水平，从而避免轴承圈之间发生偏心，造成应力集中，损伤轴承。 2. Complete the installation of the roller bearing inner ring and outer ring and, after adjusting gear ring end face parallel to the end of the spindle (red line as shown in the graphic), make the inner ring and outer ring parallel; To complete the installation of the inner ring on, positive and negative rotation bearings, roller and spacer correct orientation, to adjust the gear ring end face and inner ring on the end face of parallelism, ultimately ensure that all three bearing ring is level, so as to avoid eccentric bearing ring between, cause stress concentration, damage to the bearings. 　　3.完成上内圈安装后，必须正反转动轴承，使滚子和隔片自动摆正，再加入垫片及端盖锁紧。如果没有转动轴承而使滚子歪斜的排列在滚道上并锁紧，轴承运转时就会出现严重发热、滚道烧伤、划伤以及精度丧失等问题。 After completing the inner circle installation, the bearings must be turned on and off, so the roller and the spacer are automatically set, and then add the gasket and the cover lock. If there is no rotation and make the arrangement of skew roller bearing on the rolling path and lock, can appear when bearing is running a serious fever, raceway burns, cuts, and loss of accuracy.
