A method of operating a hydraulic power tool. The method includes performing an operation with the hydraulic power tool, detecting, with a sensor, an operational parameter during the operation of the hydraulic power tool, and storing a plurality of data points based on the operational parameter and a corresponding sampling time for each of the plurality of data points. The method also includes sending, via a transceiver on the hydraulic power tool, the plurality of data points and corresponding sampling times to an external device, displaying, on a display screen of the external device, an expected data point, and displaying, on the display screen of the external device, an actual data curve based on the plurality of data points and corresponding sampling times. The actual data curve is overlaid on the expected data point.

A flexible coupling includes a flexible diaphragm body having a first end and a second end. A member is fixed to the first end of the flexible diaphragm body. A splined member is fixed to the second end of the flexible diaphragm body. The splined member is configured to shift relative to a rotatable member rotatably fixed thereto in response to axial displacement of rotatable members interconnected by the flexible coupling. The ratio of inner diameter to the outer diameter is selected to allow for packaging the flexible coupling in a confined space.

A joining method for members according to the present invention includes: providing a steel component including insertion holes, an aluminum pipe having a hollow shape, and a support component; inserting the aluminum pipe into the insertion holes of the steel component; and enlarging the aluminum pipe through deformation and joining the aluminum pipe to the steel component by press-fitting. The press-fit joining is performed while at least part of the support component is disposed in a press-fitting region.

A press device comprising a press ring for pressing together tubular workpieces in between, and at least a first and a second pivotable jaw is described. The first jaw comprises a first engagement section and the second jaw comprises a second engagement section. The press ring comprises a first and a second receiving section for receiving the first and the second engagement section of the press jaws, respectively. A first and a second surface of the first and the second receiving section, respectively, contact the first and the second engagement section, respectively. Each comprise a planar surface, and the first engagement section comprises a first contact surface and the second engagement section comprises a second contact surface. The first and the second contact surface oppose each other for applying a press force F. The first contact surface and the second contact surface each comprise at least one convex surface, such that a radius of curvature r of the first and the second contact surface is larger than half a width Wx, Wz, measured perpendicular to an axis of curvature, of the respective first and second contact surface.

In the method, a portion of the metal tube is placed in a lumen of a metal sleeve having a metal wall surrounding the lumen. The metal tube is placed in such a manner that an outer surface of the metal tube and an inner surface of the metal sleeve at least partially contact one another. The metal sleeve is affixed on the portion of the metal tube placed in its lumen for forming a metal tube, metal sleeve, composite system. The metal tube, metal sleeve, composite system, in turn, is placed in the passageway of the metal body in such a manner that an outer surface of the metal sleeve and an inner surface of the passageway at least partially contact one another, in order thereafter by plastically deforming at least the metal sleeve of the metal tube, metal sleeve, composite system placed in the passageway to form a force interlocking between the inner surface of the passageway and the outer surface of the metal sleeve. The so formed metal tube, metal sleeve, metal body composite system can serve as a component of a measuring transducer, respectively a vibronic measuring device formed therewith.
