METHOD OF INSTALLATION CONNECTIONS MAKING USING HIGH STRENGTH BOLTS WITH CONTROLLED TENSIONING

摘要

FIELD: machine building.SUBSTANCE: method means that after the bolted connection assemblage, and prior to the final tightening on the bolt using special lubricant to ensure the acoustic contact the converter of the acoustic emission signals is installed. Then final tightening is performed during it and for some time after it the acoustic emission signals are registered, and based on the analysis results of the received acoustic emission signals the bolted joint quality is estimated.EFFECT: invention relates to connection or prevention of the relative displacement of the machine parts or structural elements, and is directed on the possibility of complete check of the bolt tensioning.1 dwg
