  • Patent number: 8302314
    Abstract: In a method for manufacturing internally and/or externally profiled rings from pipe material or solid material, machine-cutting processes and forming processes are combined with one another sequentially, parallel, or sequentially and parallel, wherein one of the forming processes is roll forming. During roll forming a counterforce is generated relative to a flow direction of the starting material so that a material flow in at least one of an axial direction and a radial direction of the starting material is controlled such that flowing material is integrated into a profile to be shaped on the ring.

  • Patent number: 8302509
    Abstract: A hydraulic bolt tensioning device has a cylinder supported on a machine part that is to be clamped by threaded bolt and nut. An exchangeable bushing has a first end screwed onto a free threaded end of the threaded bolt that projects past the nut. A tensioning piston is seal-tightly guided in the cylinder and supported on a second end of the exchangeable bushing. A pressure medium is supplied into an annular space between cylinder and piston. A control device is provided for setting a nominal pressure of the pressure medium corresponding to a nominal pretension of the threaded bolt. A yield limit detection device detects whether a yield limit of the threaded bolt is reached during tensioning. A controller acts on a pressure relief device for pressure relief of the bolt tensioning device when reaching, or shortly after reaching, the yield limit of the threaded bolt.

  • Patent number: 8297903
    Abstract: A nut for screw connections has two substantially identically sized nut segments of a half-shell shape, wherein the nut segments each have an inner side provided with an inner thread segment defining together an inner thread. The nut segments are connected to each other so as to be moveable toward each other until the nut segments reach a closed position. The nut segments are maintained in the closed position by springs or a locking device. An actuating device is moveably arranged on at least one of the two nut segments for releasing the closed position, wherein the actuating device is adapted to manually actuated.
