潤滑脂廣泛使用於傳動元件運動接觸面，以提高磨潤性能、運轉效率與延長元件使用壽命。但是在實際的使用過程中，潤滑脂因為外來入侵物引起其磨潤性能逐漸降低，以致可能無法達到原始潤滑脂之功能目標，若劣化速度增加，將嚴重影響產品品質與縮短潤滑脂的壽命。
本論文主要探討潤滑脂在外來污染液體入侵下，潤滑脂其磨潤性能與物理性質的變化及其相關性，考慮的外來液體包含有水分、切削液與防鏽油，分析對象為四種常用於高負荷傳動元件的潤滑脂，經過四球式磨潤試驗後發現:(1)四種潤滑脂的水含量越多其磨耗直徑均越大，本文並建立其水分影響磨耗與滑脂溫度方程式，以利選擇適當潤滑脂與潤滑管理的参考。(2)潤滑脂的切削油含量越多，其磨耗直徑也越大，並建立其切削油影響磨耗與滑脂溫度方程式(3)三種外來污染物在相同含量下，防鏽油的磨耗與溫度為外來液體污染物中影響抗磨耗性能最少。(4)四球式磨耗試驗前後潤滑脂中含水量皆呈現明顯下降趨勢，因此影響潤滑脂含水量除了環境的濕度水分入侵外，高負荷運傳的蒸發現象也是重要因子。(5)不同潤滑脂在三種外來污染物的影響下，所產生的磨耗特徵也皆不相同，進而可以由此來做判斷污染物依據(6)磨耗試驗後鐵粉濃度並未有明顯變化，原因是試驗時間短、量少所造成。(7)磨耗試驗前後針入度與總酸價變化不明顯並且與物化性質相關性不大，顯示磨潤界面處於磨耗初期並且氧化不嚴重，故進行試驗後針入度與總酸價數值趨勢關係不明顯。

Grease is widely used on the moving contact surface of transmission components to improve the wear performance, operating efficiency and extend the service life of the components. However, in the actual use process, the lubricating grease gradually reduces its lubricating performance due to foreign intrusions, so that it may not be able to achieve the functional goals of the original grease. If the deterioration rate increases, it will seriously affect the product quality and shorten the life of the grease.
This thesis mainly discusses the changes and correlations of lubricating grease's wearability and physical properties under the intrusion of foreign contaminated liquids. The foreign liquids considered include moisture, cutting fluid and anti-rust oil. The analysis objects are four commonly used After the four-ball lubrication test, the grease for high-load transmission components found that: (1) The more water content of the four greases, the larger the wear diameter. This paper establishes the equations of moisture affect wear and grease temperature. To facilitate the selection of appropriate grease and reference for lubrication management. (2) The more the cutting oil content of the grease, the larger the wear diameter, and the establishment of the cutting oil affects the wear and grease temperature equation (3) The three foreign pollutants at the same content, the wear and temperature of the anti-rust oil It is the least influence on anti-wear performance among foreign liquid contaminants. (4) The water content of the grease before and after the four-ball abrasion test showed a significant downward trend. Therefore, in addition to the moisture intrusion of the environment, the evaporation phenomenon of high-load transportation is also an important factor affecting the water content of the grease. (5) Under the influence of the three foreign pollutants, different greases have different wear characteristics, which can be used to determine the pollutant basis. (6) There is no significant change in the iron powder concentration after the wear test. The reason is that the test time is short and the amount is small. (7) Penetration and total acid value before and after the abrasion test are not obvious and have little correlation with physical and chemical properties, indicating that the wear interface is in the early stage of abrasion and is not severely oxidized. Therefore, the numerical trend of penetration and total acid value after the test The relationship is not obvious.
