摘要
环刷是导电滑环的重要组成部件,其接触压力是滑环使刷丝变形后产生的刷丝对滑环的作用力。环刷刷丝接触压力值微小,影响因素较多,但环刷刷丝接触压力的大小将直接关系着导电滑环的技术性能和使用寿命。本文针对环刷的特点详细研究了环刷刷丝接触压力的测量方法和技术,并设计了一套环刷刷丝接触压力检测系统,实现了对环刷刷丝接触压力的自动精密测量。
The brush is an important component of the electrical slip ring.The contact pressure of the brush probe is the interaction force between the brush probe and the slip ring when the slip ring deforms the brush probe.The contact pressure of the brush probe is minimal and can be effected by many factors,but it is directly related to the technical performance and working life of the electrical slip ring.According to the characteristics of brush,this paper detailedly studied the measurement methods and techniques of the contact pressure of brush probe,and designed a contact pressure measurement system for the brush probe.The application shows that the contact pressure of the brush probe is automatically and precisely measured.
