摘要
针对目前大部分摩擦磨损试验机实验形式单一,只能进行较为典型的摩擦磨损实验,不能模拟铲齿挖掘物料的实际摩擦工况等问题,研制了一种新型铲齿摩擦磨损试验机。通过采用由凸轮驱动的多连杆铲齿转臂运动,模拟铲齿在物料中的运动状态,采用槽轮机构和压实机构在铲齿挖掘的同时对物料进行覆平和压实,模拟铲齿挖掘时的物料状态,从而对不同工况和材料铲齿的磨损性能进行测量,为铲齿设计、检测和对比不同种类铲齿的寿命情况提供可靠的依据。
In allusion to the deficiencies of that most of the current friction and wear testers have a single experimental form,only typical friction and wear experiments can be carried out,and the actual friction conditions of the material of the shovel teeth cannot be simulated.A new type of shovel friction and wear tester is developed.By using the cam-driven multi-link shovel tooth arm movement,the movement state of the shovel tooth in the material is simulated.By employing the Geneva-wheel mechanism and the compaction mechanism to level and compact the material while excavating the shovel tooth,the material status at the time of shovel tooth excavation is simulated.Consequently,the wear performance of the shovel teeth can ne measured under different conditions and materials,and which can provide reliable basis for designing the shovel teeth,testing and comparing the life of different types of shovel.
