条形沟槽深度对船舶水润滑尾轴承材料摩擦性能的影响
|
摘要
为了研究条形沟槽深度对船舶水润滑尾轴承摩擦磨损性能的影响,在轴承试件表面分别添加0.5 mm、1.0 mm和1.5 mm 3种不同深度的条形沟槽,并加入1组不添加表面纹理的试件作为对比。使用CBZ-1船舶轴系摩擦磨损试验机对材料进行测试,并结合表面形貌及磨损量比较分析其摩擦磨损性能。结果表明,条形沟槽可有效提高材料的摩擦磨损性能且沟槽深度对材料性能有着较大影响:转速较低时,较深的沟槽深度更能提升材料的摩擦磨损性能;转速较高时,较浅沟槽深度的材料具有更加优良的性能。
In order to explore the affect of the water lubrication property from strip-type groove depth in friction surface, the experiment chooses 3 kinds of depth of strip-type grooves, which are 0.5 mm, 1.0 mm and 1.5 mm, and an extra specimen without groove to control. With the help of CBZ-1 friction wear testing machine of ship shafting, the text compares the water lubrication property of bearings with different groove depths and analyzed the principle by the analysis of surface shape and comparison of abrasion loss. The result shows that strip-type grooves can improve the water lubrication performance apparently, and the depth of the grooves affects a lot that deeper groove depth is beneficial to improve the friction and wear properties under lower spindle speed. The bearings with shallower grooves are better under higher speed.
