Development of the Automatic Detector for Wheel and Shaft Concentricity in Rail Transit Vehicle

针对传统测量工具无法快速准确测量轨道交通车辆的车轮与车轴同心度问题,设计了一种轮-轴同心度专用检测机。详细描述了同心度的检测原理以及关键组件的结构设计。该检测装置结构简单实用,能快速准确地测出车辆轮-轴同心度,大大提高了检测精度和检测效率,解决了检测技术难题,为轮对的进一步加修提供测量依据,确保车辆运行的安全性、平稳性,提高了旅客乘坐舒适度。

Aiming at the problems of traditional detecting machines that can not measure rapidly and accurately the wheel and axle shaft concentricity in rail transit vehicles,a special testing machine for wheel and shaft concentricity is designed.In this paper, the principle of concentricity detection and the structural design of key components are described in detail.The structure of the new detector is simple and practical,it can rapidly and accurately detect the vehicle wheel shaft concentricity,greatly improve the detection accuracy and efficiency,thus solving the difficult technical problems and providing the basis for wheel set measurement and repair. This detector could also ensure the safety of vehicle running and steadiness,improve the comfort of passengers.
