Design and Reliability Analysis of Wire Displacement Sensor

摘要: 随着工业现代化程度的不断提升，以及各工程行业对精度要求的逐步重视，直线位移传感器越来越广泛的应用、集成于各种工程设备当中，尤其是拉线位移传感器，以其相对低廉的价格、较强的环境适应性、优良的可靠性等优势，越来越广泛的应用于叉车、压机、升降机、起重机等行业。本文主要例举了一种拉线位移传感器总体结构，通过给定参数分别对涡卷弹簧、缠线系统、出线系统进行设计，对各个部分的可靠性风险点进行了分析及实测，包括涡卷弹簧寿命、长期运转寿命等，并且分析了整体结构设计时应注意的问题。

Abstract: With the continuous improvement of industrial modernization and the increasing emphasis on precision requirements in various engineering industries, linear displacement sensors are in-creasingly widely used and integrated into various engineering equipment, especially wire dis-placement sensors. With their relatively low price, strong environmental adaptability, and excellent reliability, they are increasingly widely used in industries such as forklifts, presses, elevators, and cranes. This article mainly provides an example of the overall structure of a wire displacement sensor. By giving parameters, the scroll spring, winding system, and outlet system are designed, and the reliability risk points of each part are analyzed and measured, including the lifespan of the scroll spring and long-term operating life. The issues that should be paid attention to in the overall structure design are also analyzed.
