轴箱

The twice failures resulted from axle box bearing breakdown are analysed.

对两起因轴箱轴承损坏造成的机车故障进行了分析，介绍了现场处理的方法、要点，并提出了几点改进建

The line dynamic test and the locomotive operations within one year after the replacement of axle box linkage indicate that the improvement works efficiently.

更换轴箱拉杆后对机车进行的线路动力学试验及试验机车改进后一年多的运用情况表明，这一改进措施起到了很好的效果。

The axles run in two-row self aligning ball bearings on the gear side, and a standard sealed ball race on the other end in the sprung axle box, both 12mm bore.

两轴运行的排调心方对球轴承齿轮，和一个标准就在轴箱弹簧的另一端密封球的比赛，两个12毫米口径。

By the instance of hydroxyl silicate mineral powder additives application on motor,the gas escape amount of bent axle box was measured,and based on the decrease feature of gas escape amount,it demonstrates that hydroxyl silicate mineral powder additive possesses self-repairing performance,and proves that the method of examination in-situ is valid.

以羟基硅酸盐矿物微粉添加剂在发动机上的应用为例，检测了发动机轴轴箱漏气量，根据漏气量减少这一特征证明矿物微粉添加剂具有良好的自修复性能，也证明此原位检测方法是有效的。

It is shown from the results that the acting force and vibrating acceleration are increased due to its axle load, however, the dynamics interaction between 25 t load wagon and the turnout can be improved by the rubber stack in its axle box, especially in the index such as derailment coefficient, reduction rate of wheel load, opening size of tongue rail and point rail, which is almost equal to the dynamics of 21 t axle load wagon.

结果表明尽管轮轨力和振动加速度因轴重增加而相应增大，但由于25t轴重货车在轴箱处采用橡胶堆，使它与道岔之间的动态相互作用有所改善，尤其是脱轨系数、减载率、尖轨和心轨前端开口量等指标上，与21t轴重货车引起的系统振动值基本一致。

The truck cast steel three big piece type bogie is easy to maintain. But since the grate weight under spring and the large operation strength during running, it is difficult for the bogie to keep the positive position. The critical speed of the snaking motion is low, which is inapplicable for high speed running. The other type of truck bogie is H type integrative truss. Its structure is complicate relatively, which is not easy to manufacture and maintain. But it can keep the positive position of the bogie preferably. And because it is adopted the structure of axle box one series elastic suspend, the weight under spring reduces. Which achieve the effective control to wheel sets and improve the running quality of the bogie distinctly.

货车铸钢三大件式转向架便于制造维修，但因其簧下质量大，在运行中轮轨作用力大，转向架难以保持正位，蛇行运动临界速度低，不适用于高速运行；货车转向架的另一种形式是"H"型构架一体式，结构较为复杂，不便于制造和检修，但它能够较好地保持转向架的正位，而且由于采用了轴箱一系弹性悬挂结构，降低了簧下质量，实现了对轮对的有效控制，明显地改善了转向架的运行品质。

The bogie for this crane is of H type weldable bogie, the primary suspension of the bogie is of journal box helical spring and wedge snubbing system.

该机的转向架是一种H型焊接构架式转向架，转向架的主悬挂为轴箱螺旋弹簧，斜楔式减振器。
