游隙或预负荷的选择，取决于升降机对轴承布局的性能和运转条件的要求。下面济南天锐升降机械的专家给大家分析一下角接触球轴承和圆锥滚子轴承的轴承布局的内部游隙调整。

1、升降平台上轴承在安装时要达到适当的游隙值，可根据轴承的负荷和工作温度状况来确定。根据轴承的尺寸和布局、轴和轴承箱的制造材料以及两个轴承间的距离，安装时获得的初始游隙在实际运转中可能会变小或变大。
Lift manufacturers introduced bearing on the lift platform during installation to achieve proper clearance values may be determined according to the load and operating temperature condition of the bearing. Size and layout depending on the distance of bearings, shaft and housing materials of construction and two bearings between the initial clearance obtained when installed in the actual operation may be smaller or larger.

2、内外圈的温差热膨胀会造成运转中游隙的缩小，因此初始游隙必须相当大，才能避免轴承变形及其不利后果。用轮毂上的千分表，检查轮毂轴承布局的设定轴向游隙。在调整圆锥滚进口轴承和测量游隙时，

轴或轴承箱需朝不同方向旋转数周，以确保滚珠端部与内圈上的导缘有适当的接触。如果接触不当，测量结果就不精确，就不能达到预期的调整目的。
Lift manufacturers differential thermal expansion comes to inner and outer rings will cause operating midstream gap narrowed, so the initial clearance must be quite large in order to avoid bearing deformation and its adverse consequences. Dial gauge on the hub, check the hub bearing arrangement set axial clearance. When adjusting tapered roller bearings and measuring the clearance, shaft or bearing housing need in different directions of rotation for several weeks to ensure that the leading edge of the inner end portion of the ball on the appropriate contacts. If the contact properly, measurement is not accurate, it can not achieve the intended purpose of the adjustment.
