摘要
该机采用V形摆动臂来驱动磨耗部分沿斜面作往复磨耗运动,V形摆动臂通过连接杆与减速电机轴上的偏心轮连接。磨耗部分可以夹持各种不同的对磨体,并可施加10～500g的磨耗压力,测试试样和对磨体在磨耗过程中始终浸于磨耗介质中。在磨耗试验前和试验后,测定、记录试样的质量、外形,比较前后的变化,可计算出试样的磨耗率及表面磨损的形态情况。
The dental abrasive testing machine applies a V-like swing arm to driving the wearing part to move along the slope back and forth, which is connected with an eccentric wheel fixed on the crankshaft of the gear motor through a connecting rod. Various abraders can be held on the wearing part with an adjustable wearing pressure between 10 and 500g loaded on the specimen. During wearing, both abrader and specimen are immersed in the wearing medium. Before and after the test, the specimen is weighed and its wearing surface is recorded by a profilometer, then the weight loss and volume loss can be calculated.
