介绍了一台高低温摩擦试验机。该试验机是为筛选高温下缸套/活塞环陶瓷摩擦副及相应的高温润滑油而设计的。该试验机采用局部加热法,温度可调范围为0～500℃。可做高低温,有油或无油摩擦磨损试验。该机为环/块线接触,环做圆周运动,块做往复运动。环圆周线速度为3.8m/s,块速为1mm/s,赫芝载荷可达2000kgcm~2。试块设计小巧独特,可直接送入多种分析仪器(俄歇、光电子能谱、红外光谱、扫描电镜、光学显微镜、声学显微镜、激光拉曼谱、形貌仪、X光衍射仪等)进行各种表面和内层结构分析。转矩、转速、功率可自动记录。本文还给出了两组用该试验机做出的数据。
Introduced a high and low temperature friction testing machine. The testing machine is designed for screening high temperature cylinder liner / piston ring ceramic friction pair and the corresponding high temperature lubricating oil. The test machine using local heating method, the temperature adjustable range of 0 ~ 500 ℃. Can be high and low temperature, oil or oil-free friction and wear test. The machine is ring / block line contact, the ring to do circular motion, the block to do reciprocating motion. Circumferential circumferential speed of 3.8m / s, the block speed of 1mm / s, Hertzian load up to 2000kgcm ~ 2. The design of the test piece is small and unique, and can be directly sent to various analytical instruments (Auger, photoelectron spectroscopy, infrared spectroscopy, scanning electron microscopy, optical microscope, acoustic microscope, laser Raman spectroscopy, profilometer, X-ray diffractometer, etc.) Various surface and inner layer structure analysis. Torque, speed, power can be automatically recorded. This article also gives two sets of data from this test machine.
