The designation of thrust ball bearing swivel flexibility Detection System

Abstract The good or bad Thrust ball bearing performance can be measured by its rotation flexibility. In this regard,our current testing technology is not mature enough and mainly using artificial sense approach. So the results obtained very large detection error . In this paper, I design and research the thrust ball bearing swivel flexibility detection system in order to achieve automatic detection and improve the detection level and efficiency.

Based on the existing detection methods and combined with the detection principle bearing rotation flexibility to design a suitable means of automated machinery. Through the LabVIEW graphical programming language programming, designed the subject of the detection system which is in line with requirements . The system consists of two parts, the mechanical structure portion and control software systems. Measurement and control system is pided into mechanical motion control and PLC can using LabVIEW to processing and analysis acquisitive data . The whole system is pided into three research areas: detection mechanism thrust ball bearing rotation flexibility, power-driven solutions for automated production lines, natural decay K speed computational rate. Part of the mechanical structure is realized on the basis of detection and monitoring and control software is the core of the system. Through experimental verification we can know that designed detection system have high reliability and high practical value.

This article is about the thrust ball bearing swivel flexibility detection system design and final design experiments have verified the accuracy of the system.
