An online automatic measurement system for the widths of tapered roller bearings was presented,which consisted of mechanism and control system.According to the measuring principle,the mechanism can automatically implement measurement procedure including preliminary positioning and precision positioning of the measured bearings.The structures of hardware system and software system were described respectively.Movement procedure control was accomplished by a PLC,while bearing width measurement and data processing were done by Industrial Personal Computer（IPC）.Based on virtual instrument technique,the software was programmed based on LabVIEW.Experimental results show that the measuring accuracy of the system is ±3.1 μm,and its efficiency is 16 s/set.The developed system,with higher accuracy and speediness and also without operator,can satisfy the requirement of bearing width automatic measurement in the automatic assembly-line for the tapered roller bearing.
