Abstract: A guide sleeve includes an outer bushing, which encloses an inner bushing with radial clearance, an elastic spring member made of an elastomeric material being arranged in gap created by the clearance, and inner bushing having at least one lubricant pocket open radially to the inside.

Abstract: A holder for the vibration-decoupled fastening of a substantially flat machine part having at least one recess. The holder has a hollow cylindrical sleeve manufactured of a tough, preferably metallic, material which is surrounded radially on the outside--in a non-rotatable manner--by an elastomeric body. The body has an annular groove surrounding the sleeve, which groove has an axial size which corresponds substantially to the thickness of the machine part and a groove bottom which is adapted to the shape of the recess. The groove bottom and the limitation of the recess can be brought into engagement with each other under initial elastic stress.

Abstract: An apparatus for supporting conductor bars of an end winding of a stator winding of an electric machine having a lamination stack includes pressure plates holding the lamination stack together, support angles supporting the conductor bars in the vicinity of the end winding, a support ring being directly axially adjacent the pressure plate and having an inner periphery, the support angles having radially outer surfaces braced against the support ring, the support angles being guided and partially disposed in radially extending slots formed in the pressure plates, and spacers in the shape of ring segments resting on the inner periphery of the support ring and preventing tangential deflection of the support angles.

Abstract: Rotating rectifying device for excitation of a synchronous machine. The device includes an armature mounted on the machine shaft in a magnetic field with rotating coils connected to rectifier assemblies mounted on the inside flange surface of a support wheel, also mounted on the machine shaft. Each rectifier assembly has a first cooling body mounted on the inside flange surface, and a second cooling body that is resiliently spring biased with an outwardly facing surface against a disc-shaped semiconductor rectifier that rests with its other surface against the first cooling body. The second cooling body has parallel ribs that project into the circular space formed by the support wheel flange. In one version of the invention the second cooling body and the spring element is of circular construction.

Abstract: A stator conductor terminal assembly is located at the underside of the housing of a three-phase turbo-generator for leading out the phase windings from the stator coil head. The assembly includes three fully insulated liquid-cooled tubular lead-off conductors connected respectively to the phase windings and each such conductor includes a first section directed vertically downward, a second section directed horizontally for different distances and a third section also directed vertically downward and which is shielded in a metallic box-like enclosure. A current transformer surrounds the third section of the conductor within the box-like enclosure and the lower end of the third section which passes through the open bottom of the enclosure is connected to a terminal which latter is connected to an outgoing phase line. Metallic tubular shielding surrounds each phase line and this shielding is connected by way of electrically conductive bellows to the box-like enclosure.

Abstract: A stator conductor terminal assembly is located in a casing attached to the underside of the housing of a three-phase turbogenerator for leading out the phase windings of the stator coil heads. The assembly includes three liquid-cooled hollow conductors connected respectively at one end to corresponding hollow switching leads, the conductors extending from the switching leads in a first section vertically downward, thence in a second section directed horizontally for different distances, and then vertically downward in a third section through an elastic support carried by an insulating plate. The third sections of the hollow conductors pass outward through the bottom of the casing and terminate in polygon-shaped connection terminals. The casing also includes current transformers located below the insulating plate between the third sections of the hollow conductors.

Abstract: An arrangement for supporting the head portions of the coils which project beyond the ends of the slots provided in the laminated stator component of a high-output turbo-generator in which the coils are placed includes inner and outer radially spaced rings made from a glass fiber-reinforced thermosetting synthetic resin and between which the cylindric array of the insulated coil heads is secured, and a supporting ring secured to the general housing structure of the generator which surrounds and is spaced radially from the outer coil head securing ring. A ring structure of a rubber-like resilient material, e.g. india rubber is interposed between and contacts corresponding faces of the supporting ring and the outer coil head securing ring for the purpose of compensating for unequal expansion coefficients of the copper conductors of the stator coils and the iron of the laminated stator component.
