钻机传动装置中轴承动负荷选择计算

The sizing calculation for dynamic load of bearing in the driving unit of the drilling rig

钻机传动装置是钻机工作过程中的动力枢纽 ,其可靠性对整台钻机的使用寿命起着至关重要的作用 ,因此传动装置中轴承的选择是设计者考虑的一个重点。现文着重根据实际工作中对轴承的选择应用 。

The driving unit of drilling rig is the dynamic pivot on its operating,and the reliability of the driving unit will play a very important role to the operating life of the whole drilling rig.So the collection of the bearing is the key point that should be considered by the designer.This paper bases on the collection and application of the bearing in the writer's practice work to introduce the collection calculation of the bearing according to the dynamic load.
