  • Publication number: 20190264747
    Abstract: A bearing includes a first ring, a second ring and a plurality of rolling elements between the first and second rings. The first ring is a split ring formed of a first ring part and a second ring part that meet at a joint region, and each of the ring parts includes a recess that extends axially into the respective ring part from the joint region. A cylindrical seal is disposed in the recess of the first ring part and extends across the joint into the recess of the second ring part.

  • Publication number: 20150115612
    Abstract: The invention relates to a rotor for a dynamo-electric machine having: a rotor body which rotates about a rotation axis which runs in the direction of gravity, winding elements which are arranged in slots which run axially in the rotor body, two winding heads which are arranged above and below the rotor body in the axial direction, wherein the winding elements emerge from the slots in the axial direction in the region of the winding heads and are connected to further winding elements, a winding head carrier for each of the winding heads, which winding head carrier is arranged radially within the winding head and coaxially to the rotation axis, and which winding head carrier is fixed at least indirectly on the rotor body, or on a component which revolves with said rotor body, in a rotationally fixed manner and such that it can move in the direction of the rotation axis.

  • Patent number: 8922088
    Abstract: Provided is a rotor for a dynamoelectric machine. The rotor includes winding elements arranged in axially extending grooves of a rotor body, a winding head arranged axially adjacent to the rotor body, and a winding head carrier, connected to the winding head by means of tension bolts, all arranged in such a way that reliable securing of the winding head against radial expansion due to centrifugal forces is ensured, while resulting in a compact and cost-effective configuration as well as sufficient cooling.

  • Patent number: 8872404
    Abstract: A dynamoelectric machine includes a rotor body, an annular winding head which is arranged axially next to the rotor body and coaxially in relation thereto, a support ring which is arranged radially inside the winding head and coaxially in relation thereto, the winding head and the support ring are torsion-proof with the rotor body, the winding head and the support ring are clamped together in the radial direction by tension rods which are guided through radial boreholes in the winding heads and in the support ring, where radially inner ends of the tension rods engage on the support ring and radially outer ends of the tension rods engage on bearing blocks which rest on the winding head, and the radially inner ends of the tension rods and the radially outer ends of the tension rods are mounted by the bearing blocks having a spherical surface.

  • Publication number: 20130187493
    Abstract: The invention relates to a rotor for a dynamoelectric machine, having the following features: winding elements which are arranged in axially extending grooves of a rotor body; a winding head which is arranged axially adjacent to the rotor body, wherein in the region of the winding head the winding elements exit the grooves in the axial direction, then extend at an angle to the axial direction, and then extend in the axial direction again in the vicinity of the axial ends of said winding elements, and are connected with further winding elements; a winding head carrier which is radially arranged within the winding head; the winding head is connected with the winding head carrier by means of tension bolts which engage at the radially outer ends thereof on support bodies, which in turn lie on the winding elements in the region of the winding head; the tension bolts penetrate the winding head in the radial direction in the axially extending areas or the areas of the bending of the winding elements from the axia

  • Patent number: 6933647
    Abstract: The novel squirrel-cage rotor should enable a power output of the motor of more than 1 MW even at rotation speeds of more than 10,000 rpm. To this end, the conductor bars (4) of the squirrel cage are soldered into slots (8, 9) arranged on the periphery of the massive rotor core (3) across their entire length, and the conductor bars are arranged to be flush with the surface (13) of the rotor core (3).
