项目摘要
In order to realize new transmission and brake systems with small volume, high friction coefficient and wear resistance will be needed for sliding elements. Carbon fiber brush will be one of the promising elements if it have high friction coefficient and wear resistance. In this research, we proposed a loop-type carbon brush to avoid the sever wear of carbon brush from the edge. The proposed loop-type one showed 1/10 of wear volume compared to the normal-type carbon brush. In order to improve the friction coefficient of carbon brush, electric voltages were applied to the brush as 100 V, 200V and 300V. However electric voltages could not change the elastic stiffness of carbon bush.
为了实现体积小的新型传动和制动系统,对滑动元件提出了高摩擦系数和高耐磨性的要求。碳纤维电刷具有较高的摩擦系数和耐磨性,是很有前途的电刷元件之一。在本研究中,我们提出了一种环形碳刷,以避免碳刷从边缘严重磨损。所提出的环形碳刷的磨损量是普通碳刷的1/10。为了提高碳刷的摩擦系数,对碳刷施加100 V、200 V和300 V的电压。而电压并不能改变碳瓦的弹性刚度。
