轴承检测装置的设计

摘要

轴承是各类机械装备中最为重要的基础部件，它的精度、性能、寿命以及可靠性对主机的精度、性能、寿命以及可靠性起着非常重要的作用。在机械产品中，轴承属于高精度产品，不仅需要数学、物理等诸多学科理论的综合支持，而且需要材料科学、热处理技术、精密加工和测量技术、数控技术和有效的数值方法及功能强大的计算机技术等诸多学科为之服务，因此轴承又是一个代表国家科技实力的产品。随着工业水平的不断进步、生产自动化水平的不断提高，轴承已经广泛的应用在好多行业领域，它的质量直接影响到工作母机的工作性能，其精度的高低直接影响到整个设备性能的好坏。据统计在旋转机械中30%的故障与轴承有关。因此，工业生产监控的要求也越来越高，为了保证轴承质量必须对其进行严格的出厂检测。目前在轴承检测项目中：轴承游隙检测、内径检测以及振动情况检测等项目，都是反应轴承质量的重要指标，轴承的合格与否将会直接影响到轴承的使用性能。现有的轴承检测仪一般只能进行单一项目的检测，检测效率低不方便。为了满足轴承安全检测的要求，研制出一种检测效率高、基本实现自动化的轴承多方面检测项目的检测装置显得越来越重要。

Abstract

Bearing is the most basic components in all kinds of the mechanical equipment, for its accuracy, performance, life and reliability plays a very important role of the host's accuracy, performance, life and reliability. Bearing is a high precision product in the mechanical products, not only its needs a comprehensive support for math, physics and other disciplines theory, but also needs the material science, heat treatment technology, precision machining and measuring technology, numerical control technology and numerical method is effective and powerful computer technology and other disciplines to serve its, so the bearing is the products that represents of the national scientific and technological strength. Along with the automation level of continuous improvement, the level of industrial production increasing, application field of bearing has been widely in many industries, it directly affects the quality of the work performance of machine tools, and its precision directly affects the performance of the whole device is good or bad. there are 30 percent of faculties in the rotating mechanism to be relative to bearings. so we must strictly check the qualities of bearings before they are sold .At the present in the bearing detection project, Bearing clearance detection, inner diameter measurement and vibration detection project, is an important indicator of the quality of the bearing.Weather the bearing is qualified or not,it will directly affect the bearing performance. Detection of the existing bearing tester is generally only for a single project, low detection efficiency is not convenient. In order to meet the requirements of bearing safety detection, developing a detection for higb detecting efficiency ,and the basic realization of automatic bearing detection project becomes more and more important.
