装拆液压升降货梯轴承要注意什么？

1.施力的合力尽可能通过液压升降货梯轴承的轴线，这就要求施力点均匀对称而平稳，通过球面或平行于轴线施力。As possible to force the axis hydraulic cargo lift bearing, which requires the application point of symmetrical and stable, with spherical or parallel to the axis force.

2.施力的大小宜平稳均匀，不宜有冲击，这就要求采用油压或用能施加平稳拉力或压力的工具，实在不得不采用锤击时，也要通过铜套筒等较软而不落屑金属加以缓冲，敲击力尽可能轻缓。最好使用铜棒或铜锤进行锤击。The size of the force should be smooth and uniform, not a shock, which requires the use of oil pressure or tension or pressure can exert a stable tool, we have to use the hammer, but also through the copper sleeve soft scrap metal does not fall into the buffer, strike force as gentle as possible. It is best to use copper or copper hammer.

3.避免通过滚动体施力，这就要求装拆液压升降货梯内圈(轴圈)时通过内圈施力，装拆外圈时)通过外圈施力。Through the rolling body to avoid the force, which requires the installation of hydraulic lift cargo ladder inner ring (shaft) when the force through the inner ring, the outer ring of the outer ring.

4.拖力要持续到应有的程度，例如在安装液压升降货梯轴承时要在轴承刚好装到正确位置时停止施力，保证套圈(垫圈)的端面抵靠座孔或轴的挡肩端面，既不能挤得太紧，又不能装不到位。Drag to continue to the extent, such as the installation of hydraulic lifting elevator bearing when the stop force in the bearing is installed at the correct position, ensure the ring (washer) end against the abutment face hole or shaft, can not packed tightly, they can not be installed in place.
