轴承巴氏合金

The rotor, supported by babbitt metal made bearing, suspends on the bearing pad thanks to oilfilm lubrication by the fuel feeding system. The end clearances can be adjusted automatically to make oilfilm on both ends the same thickness and ensure no leakage. Compared with screw compressors whose output ends would clasp, this compressor has no possibility of the bearing and rotor biting together.

采用航空级的巴氏合金轴承支撑的转子，通过供油系统提供的油膜润滑：转子能悬浮与轴瓦上，并自动调节端面间隙，使两端油膜厚度相并无泄露，该轴承能保证转子轴绝无咬死之可能，而螺杆压缩机因受轴向力的作用排气端间隙，容易有咬死，抱紧现象。

In This paper, the feature of temperature rise rate of bearing bush when bearing brass is ablated is determined. Furthermone, the percentage of bearing clearance reduction as time is given.

本文确定了轴承巴氏合金烧蚀的轴瓦温升速率特征，同时给出了相应的轴承间隙随时间减小的百分率。

The temperature change of bearing bush is the most obvious feature of ablation of bearing brass.

轴承巴氏合金烧蚀最明显的特征是轴瓦温度的变化。

The chips of bearing brass caused by solid, liquid or gas will all go into the lubrication oil.

无论是固体作用、液体作用还是气体作用所引起的轴承巴氏合金碎裂均会使巴氏合金剥落物进入润滑油之中。

Since tin is the main Component of brass, the radio of tin to iron of the oil can be used to determine if bearing brass break and the breaking degree.

而巴氏合金的主要成分为锡，因而本文提出用润滑油中锡铁含量之比来确定轴承巴氏合金是否碎裂及碎裂程度。

The physical model established takes into account the lubricating oil film, thrust bearing, runner and thrust head. The thermo elastic deformation of the thrust bearing and runner was analyzed based on ADINA program.

物理模型包括润滑油膜、推力轴承和镜板推力头，采用ADINA程序计算水口巴氏合金瓦和三峡弹性金属塑料瓦推力轴承和镜板推力头的热弹性变形，并对轴承性能的计算结果和测量结果进行了对比分析。
