Design and Analysis of Online Automatic Tester for Rolling Bearing Vibration
Abstract
The quality of rolling bearing Call dkectly influence the working performance of mechanical they need to be tested rigorously in order tO ensure the quality of the bearing on ex- vibration test of bearing is all important process,and the bearing vibration tester is an important instrument for testing bearing,which is widely used in bearing production enterprises and research institutions.
At present,most of the bearing vibration testers that have been put into use are manual
operation or semi-automatic operation,so they Call not realize full-automated testing in production assembly ,it will hindering the development of bearing tO high precision,10W vibration and bined with enterprise needs,and according to the new rolling bearing vibration measurement method having been implemented fxom April 2010,a further research on axial loading mode,10ad capacity of spindle,handling system and automatic control has been carried on。Based on empirical design and simulation,automatic bearing vibration tester that Call meet the requirements of online testing has been designed. 111e main contents are as follows:
(1)Based on the analysis and research of bearing vibration tester at home and abroad,
combined with the testing requirement of bearing production assembly linej a new test method has been proposed,which Can test both sides of the bearing at the same a new handling mechanism has been designed,which call transport and clamp bearing by two
cylinders.
(2)According to the new rolling bearing vibration measurement method,in view of the problem existed in the main spindle of insufficient bearing capacity for deep groove ball bearing with largest outside diameter of 260mm,the main spindle system has been designed and studied based on classical hydrodynamics and dynamic analysis of main spindle system has been t
