Method for establishing a foundation in particular for a tower of a wind energy plant

The invention relates to a method for building a foundation for a structure comprising a plurality of segments, in particular for a wind turbine tower, a foundation segment for use in such method, and a wind turbine. In order to create a stable foundation, a method comprising the following steps is proposed on the basis of experience gained:_excavating a foundation bed,_building a stable, substantially level and horizontal subbase in a foundation bed, setting down a foundation segment of the structure on the subbase, wherein at least three vertically adjustable support poles are fixedly attached to said foundation segment by means of a supporting bracket mounted at the end of the support poles in such a way that only the support poles are placed onto predetermined points of support on the subbase,_producing a reinforcement on the subbase,_filling the remainder of the foundation bed with foundation mass, in particular concrete, to a level above the bottom rim of the foundation segment.

Toothed Wheel For a Play-Free Gear Spur Set

A toothed wheel is described for a play-free spur gear set, comprising a hub (1), with a toothed ring (2) supported by the hub (1), which ring is split into two partial rings along a dividing plane normal to an axis, namely into a ring piece (3) fixed to the hub and a ring crown (4) mounted to rotate coaxially relative to the above, and an annular spring (5) enclosing the hub (1) with the circumferentially-opposed ends (6) resting on support webs (7, 8) embodied integrally with both partial rings, overlapping each other in the axial direction and arranged behind each other in the circumferential direction of the toothed ring. In order to avoid any overload of the partial rings produced by way of powder metallurgy and to ensure simple constructional conditions it is proposed that the support web (8) of one partial ring extends through the other partial ring in a through opening (9) with circumferential play and the support web (7) of the partial ring with the through opening (9) forms an assembly stop (10) defining the through opening (9) for the other support web (8).
