    Abstract: A tool for cyclo-palloid gear hobbing includes a head and a plurality of milling inserts protruding from a front side thereof. The milling inserts are mounted, two by two, in chip removal units that are detachably connected to the head. Each milling insert is clamped by a wedge and a screw that are easy to access. The wedge acts tangentially against the milling insert behind which there is a tangential support in the form of a shoulder. By clamping the milling insert with a respective wedge the milling inserts can be mounted and dismounted in a simple way, and each group of wedge+milling insert+tangential support can be located tangentially and thereby efficiently carry the cutting forces acting on the milling insert. In further aspects, an insert holder intended for the tool, a chip removal unit of an insert holder and an insert kit are disclosed.

  • Publication number: 20150132092
    Abstract: A five-legged moving and storage container has self-leveling or self-raising ability: two wheeled legs at the second end of the device extend as the first end is pulled up a tilted tow truck bed. By extending the legs to raise the second end of the moving container at the same rate that the first end is pulled up the slope of the bed, the container is maintained level. As the tow truck bed is leveled, the legs can then be retracted to match and again the device remains level. No special infrastructure is required: it may be loaded and unloaded in any location having a normal flat-bed tow truck. It may have three additional legs at the other end: one in the middle with a wheel, two at the corners without, allowing it to raise itself or be raised and stabilized at dock height.

  • Publication number: 20150132111
    Abstract: A variable-vane assembly has a nozzle ring supporting an array of pivotable vanes, and a unison ring for pivoting the vanes in unison. A crank mechanism rotatably drives the unison ring, and includes an external crank assembly positioned radially outward of the unison ring, a non-round drive block disposed in a non-round recess in an outer periphery of the unison ring, and a crank arm having a forked end connected to the drive block and an opposite end connected to the external crank assembly. The forked end defines two legs and the drive block is disposed between the legs and is pivotally connected to the legs such that the drive block is pivotable relative to the crank arm about a pivot axis. The crank mechanism is arranged such that the crank arm is caused to swing through an arc of movement, thereby rotating the unison ring.

    Abstract: A variable turbine geometry (VTG) exhaust-gas turbocharger in which guide vanes are adjusted by means of a unison ring, the structure of which has a simpler and thus more cost-effective design. The number of components is reduced, for example for rollers on pins as are provided in the case of known bearings. A very beneficial relationship between friction radius and rolling radius in the given installation space is obtained.

  • Publication number: 20150132119
    Abstract: A method for establishing access for mounting and dismounting of main shafts, gearbox, generator and other main parts located in the nacelle of a wind turbine, where the cabriolet remains localized on the nacelle, and guide transfer mechanisms are provided for mounting inside the nacelle. The basic idea is that the cabriolet is lifted upon rolls or roll sets which form the guide transfer mechanisms upward facing support surfaces, and that the cabriolet is stabilized by displaceable counter holds which are displaced and locked in position above the downwards positioned mounting flange, upon which the cabriolet can be displaced on the rollers or roll sets to a partly cantilevered position over the rear end of the nacelle. By the method, service on larger wind turbines can be performed without using mobile cranes, which saves resources.
