面向高温环境的环块摩擦磨损试验机 设计 摘要：为测试高温环境下的各种润滑油和润滑脂的润滑性能以及评定金属和非金属材 料的磨损性能，本文主要讲述了一款面向高温环境的环-块式磨擦磨损试验机的设计 过程。所设计的试验机的两试样的接触形式为环-块式，可进行在最大载荷为 200 N 、 最高转速为 1000 r/min、最高温度达 100℃的条件下的摩擦磨损试验，以探究摩擦磨 损机理。本文对所设计的摩擦磨损试验机的机械部份进行了计算、设计、校核、仿真 及其三维建模，可为类似的试验机的研制提供一些的依据。 本文具体内容有：首先，根据面向高温环境的摩擦磨损试验机的要求和指标，确 定了本设计的总体方案。然后，完成试验机机械结构的详细设计及校核，其中包括加 载装置、装夹装置、传动部分、加热系统、机架。利用 Creo3.0 完成三维模型的建立 并完成装配，随后导入 ANSYS 进行仿真，再次校核各重要零件的强度是否满足要求， 再借助 CAD 绘制零件及总装配图纸。最后，针对本文设计的试验机，进行了相应的 性能分析。 关键词：环-块；摩擦磨损试验机；高温环境；机械设计 Design of ring friction and wear testing machine for high temperature environment Abstract: In order to test the lubrication performance of various lubricating oils and greases under high temperature environment and to evaluate the wear performance of metal and non- metal materials, this paper designs a ring-block friction and wear testing machine for high temperature environment. The contact form of the two sample tester is a ring - block, can be carried out in the maximum load of 1000 N, the maximum speed of 1000 r/min, the highest temperature of 100 ℃ under the condition of friction and wear test, in order to explore the mechanism of friction and wear. In this paper, the mechanical part of the friction and wear testing machine is calculated, designed, checked, simulated and three-dimensional modeling, which can provide some basis for the development of similar testing machine. The specific contents of this paper are as follows: first, according to the requirements and indicators of the friction and wear testing machine for the high temperature environment, the overall scheme of this design is determined. Then, complete the detailed design and check of the mechanical structure of the test machine, including the loading device, clamping device, transmission part, heating system, frame. Creo3.0 was used to the establishment of 3d model, then ANSYS was imported for
