磨料磨损试验机的设计 摘要 目前磨料磨损试验机的品种繁多，也有不少人在研究新型的试验机。在国内的相关研究中则广泛使用的试验机有滚子式磨损试验机、四球式磨料磨损试验机、往复式磨料磨损试验机、磨损试验机、盘销式磨料磨损试验机等。磨料磨损试验的目的是为了对磨损现象及其本质进行研究，正确地评价各种因素对磨料磨损性能的影响，从而确定符合使用要求的摩擦副元件的最优参数。 我所设计的是磨料磨损的试验机。是用电机带动带轮为驱动，利用带式传动使整台设备运转。这种试验机是进行磨料磨损的有效设备，广泛运用于对各种高速刀具的磨损性能进行测试和评价，是高速切削和新型刀具材料研制开发和应用的必备设备。该设备是高速加工和刀具材料研究方向研究工作急需的基础设备，该设备可以扩展该学科的研究领域和提高研究水平。是综合各种试验机的一种先进的设备。 关键词：磨损；试验机；高温；高速 Abstract The abrasivewear test machi
