打井机具轴承改代轴承在打井机械中起着重要的作用,运行中证明,绝大部分轴承设计合理,经久耐用,但也有某些部位轴承容易损坏,如转盘00、提引水龙头、泥浆泵连杆上的轴承等。寻其原因不单是质量问题,而且结构上也存在着某些缺点。为解决这个问题,经过多次实践,我们找出了改代轴承的简易方法。现简要介绍三个部位轴承的改代办法。一、转盘300上下轴承的改代上下滚珠轴承装有25.4毫米的滚珠48个,是转盘300型钻机的重要机件之一,用以承受钻机工作时钻具自重产生的轴向力。从
Drilling machine bearings to replace the shaft bearing drilling machinery plays an important role in the operation proved that the vast majority of bearing design is reasonable and durable, but there are also some parts of the bearings easily damaged, such as turntable 00, cited taps, mud Pump connecting rod bearing. The reason is not only the quality problem, but also some shortcomings in structure. To solve this problem, after many practices, we find a simple way to replace the bearing. Now briefly introduce the three parts of the bearing replacement method. First, the turntable 300 up and down the ball bearing upper and lower ball bearings fitted with 25.4 mm balls 48, is one of the important parts of the turntable 300 drilling rig to bear the boring rig work deadweight axial force.
