摘要： A tensioning device for elongating a screw assembly, provided with threaded bolt and threaded nut supported on a fixed substructure, by applying a traction force to a free threaded end of the threaded bolt has a cylinder housing with internal wall and a piston movable in the cylinder housing in longitudinal piston direction. The piston together with the internal wall delimits a hydraulic operating space. A replaceable bush entrained by the piston in the longitudinal piston direction has a thread with which the bush can be screwed to the threaded bolt. A support tube is disposed on the cylinder housing, is supported on the fixed substructure, and surrounds the threaded nut. A lock bar is disposed on the support tube and has a lock-bar face facing the piston. The lock-bar face bears on a blocking face of the threaded nut that faces away from the piston.

摘要： In a tightening method for a screw connection of a bolt and a nut by using a tensioning device, a rotary drive, and a process control unit with documentation module, the nut is tightened with the rotary drive by a tightening moment required for the nut to bear against a support. The screw connection is elongated by exerting axial tension on a threaded end of the bolt protruding from the nut. The nut is further tightened while maintaining elongation, and a rotation angle covered during further tightening is detected by a rotation angle sensor. Lengthening of the bolt is calculated from the rotation angle and thread geometry of the screw connection. A longitudinal force in the threaded bolt is calculated from lengthening of the bolt, bolt diameter and bolt length. The calculated longitudinal force and an identifier identifying the screw connection are stored in the documentation module.

摘要： A device for tightening a screw connection on a flange connection is provided with a tool carrier movable along the flange connection and provided with a traction drive. A tool is arranged on the tool carrier for tightening the screw connection and rotating the nut relative to the flange connection. A control unit is provided for moving the tool carrier in longitudinal direction of the tool carrier into a working position by traction drive control signals. In the working position, the tool is opposite the screw connection to be tightened. The control unit performs, by tool control signals, tightening of the screw connection and rotating of the nut. The control unit has a travel control module with travel controller for moving the tool carrier into the working position. The travel controller stops the traction drive after a predefined travel length has been reached that is a target variable.

摘要： A tensioning device for threaded bolts has a supporting tube and a cylinder with a hydraulic supply connected thereto. The supporting tube surrounds the threaded end section of the bolt. A piston is moveable in the cylinder longitudinally. An exchange socket is connected to the piston and driven axially by it. The exchange socket has a first end with internal thread to be screwed onto the threaded end section and a second end with an external polygon member. A tool attachable to the external polygon member enables turning of the exchange socket. The tool has a cup-shaped section having a first open end and an inner side with tool faces that engage the external polygon member. The tool has a drive section that is slimmer than the cup-shaped section and connected to a second end of the cup-shaped section. The drive section extends away from the cup-shaped section.

摘要： A nut for a screw connections has, in the circumferential direction, segments that are substantially of the same size, abut one another in separating planes, and are movably guided relative to one another between an open position and a closed position. Closing elements serve for movement of the segments toward one another into the closed position. In order to provide a segmented nut that is suitable for many applications in facility and apparatus engineering, the segments are pivotable relative to one another and connected for this purpose in a first end area in a pivotable way. The closing elements load the segments in the second end areas.

摘要： A screwed connection has a threaded bolt; a nut; a washer arranged between the nut and a surface of a component to be clamped; a screwing device with a housing, a holding tool connected to the housing, and a tightening tool that engages positively the nut; a measuring element arranged in the washer for measuring a compressive force generated by tightening the screwed connection. The washer has an anti-rotation device oriented toward the surface of the component. The outer periphery of the washer is positive-lockingly engaged by the holding tool. The washer has no positive or frictional connection to the threaded bolt, and the holding tool has no torque supporting action on the threaded bolt or on any other part so that a reaction moment, generated when tightening the nut, is introduced from the housing of the screwing device through the washer into the component to be clamped.
