METHOD FOR CONTROLLED TIGHTENING OF FIXATION PARTS

摘要

Method for control tightening of fixation parts includes installation of bolt to opening of parts being assembled, screwing nut with fixation of torque at achieving minimal gap between support surfaces of bolt head and part being assembled loaded with rated force. Besides that initial compression of parts being assembled with rated tightening force of fixation parts is formed by screwing nut to bolt controlled with dynamometric device installed on the head of bolt that rests on part being assembled, with fixation of value of torque for turning on nut and at minimal gap between support surfaces of bolt head and part being assembled following removal of dynamometric device and additional screwing on of nut with torque to value fixed before.
