一种轴类零件静动态形变量在线监测装置及方法
摘要：
本发明公开了一种轴类零件静动态形变量在线监测装置及方法，包括基座(1)，伺服电机(2)，联轴器(3)，转速传感器(4)，被测轴类零件(5)，末端活动支撑(6)，限位导向板(7)，激光测距传感器阵列(8)，丝杠(9)，步进电机(10)，滑块(11)，滑动平台(12)，滑动导轨(13)等。本发明可以用来测量两类形变：1、动态时，即伺服电机带动被测轴类零件高速转动时，用来测量被测轴类零件横截面处由于动不平衡载荷作用下产生的形变大小；2、静态时，测量被测轴类零件在任意横截面处偏移其原轴心的距离和角度；实用性好。
摘要（英）：

The invention discloses an online monitoring device and method for static and dynamic deformation quantities of a shaft part. The device comprises a base (1), a servo motor (2), a coupling (3), a speed sensor (4), the monitored shaft part (5), a tail end movable support (6), a limiting guide plate (7), a laser ranging sensor array (8), a lead screw (9), a stepping motor (10), a sliding block (11),a sliding platform (12), a sliding guide rail (13) and the like. The device can be used for measuring two kinds of deformation: 1, in a dynamic state, namely, when the servo motor drives the monitored shaft part to rotate at a high speed, the device is used for measuring the deformation generated under the action of a dynamic unbalanced load at the cross section of the monitored shaft part; and 2, in a static state, a distance and an angle between any cross section and the original axis of the monitored shaft part are measured. The practicability is high.
