【摘要】：為了研究在不同載荷下滑塊軸承Stribeck曲線的變化規(guī)律,建立了銷盤式摩擦實驗臺,通過改變載荷、轉速采集到油膜厚度和摩擦因數,運用MATLAB軟件繪制摩擦因數與壓力、轉速和黏度的關系曲線,即Stribeck曲線。實驗結果表明,摩擦因數隨著轉速的增加呈現先減小后增加的趨勢;載荷越小,進入Stribeck曲線谷底越早,越容易達到流體潤滑狀態(tài),通過改變軸承的載荷能夠有效地改善軸承的潤滑狀態(tài)。
[Abstract]:In order to study the variation rule of Stribeck curve of sliding block bearing under different loads, a pin-disc friction test bench was established. The oil film thickness and friction coefficient were collected by changing load and rotational speed, and the friction coefficient and pressure were drawn by MATLAB software. The relationship between rotational speed and viscosity, that is, Stribeck curve. The experimental results show that the friction coefficient decreases first and then increases with the increase of rotational speed, and the lower the load is, the earlier the friction coefficient reaches the bottom of the Stribeck curve, and the easier it is to reach the state of fluid lubrication. By changing the load of the bearing, the lubrication state of the bearing can be improved effectively.
