Abstract: A generator drive for matching the rotation speed of a gas turbine to an electricity generator. The drive from the gas turbine is introduced by a sun wheel into planet gears of a first epicyclic gear stage and is driven via further planet gears of a second epicyclic gear stage, which are each arranged on a common planet gear shaft with the planet gears of the first gear stage, by an annular gear to the generator. The planet gear shafts are mounted in bushes which can each be inserted complete with the planet gears into openings on a supporting wall of the drive. With respect to their distances from the bearing, the planet gears are arranged on the planet gear shaft such that the moments which result from the circumferential forces about the bearing essentially cancel one another out.

Abstract: An adjustable bearing assembly includes a bearing housing and a bearing body fixed to a carrier and disposed within the housing. Set screws are provided to adjustably position the carrier, hence the bearing body relative to the housing without disassembling the bearing. After the bearing body position has been adjusted, cap screws are employed to fix the carrier against movement relative to the housing and relative to a support surface. In an alternate embodiment, the carrier is in engagement with an inner eccentric ring which, in turn, is engaged by an outer eccentric ring, both rotatably mounted within the housing. The axes of the eccentric rings are spaced from one another and are parallel to the axis of the rotating shaft. Rotation of the eccentric rings relative to one another and to the housing adjusts the position of the bearing body.

Abstract: A shaft seal includes a plurality of axially spaced annular sealing rings which define oil collection channels. A radial drain aperture extends from the bottom of each channel into an interior trough which extends axially to a discharge orifice in a front end wall of the seal. The bottom of the trough is downwardly inclined for enhanced gravity flow. A portion of the outer periphery of the seal which projects into the housing is outwardly flared and includes a lower discharge lip to provide a return flow surface which directs return flow of sprayed oil away from the seal.

Abstract: A bearing assembly includes a bearing base and a plurality of tiltable shoes. A ceramic plate is bonded to each shoe and a face surface of each ceramic plate provides a bearing face. Tilting movement of the shoes relative to the bearing base provides a fluid lubrication film wedge between the bearing faces and the running surface of a moving load. The ceramic plates are separately produced and are bonded to the surface of the shoes, which are formed of relatively soft material, by adhesive, soldering, welding or sintering. The running surface of the load may be formed of a ceramic layer. The ceramic plates are formed of silicon carbide which is fiber reinforced.

Abstract: A combined journal-thrust bearing assembly includes a bearing body formed of upper and lower sections secured together at an axial plane. To the axial ends of the bearing body, thrust rings are removably mounted with the thrust rings also being formed of segments, the ends of which lie in the axial plane. Extending through a bore defined by the bearing face of a journal liner is a rotating shaft having a pair of spaced collars. The collars abut bearing faces of the thrust rings to prevent axial movement of the shaft relative to the bearing assembly. Disassembly of the bearing body about the axial plane facilitates repair or replacement of the bearing body sections, the liner, or worn thrust rings independently of one another. An oil delivery system is also provided for lubricating the interface between the shaft and the journal bearing face as well as lubricating the interface between the thrust bearing faces and the shaft collars.

Abstract: A journal bearing assembly includes a steel bearing body and a Babbitt metal liner which defines an internal bearing surface and provides a sliding bearing for a rotating journal. A porous metal bonding layer of NiAl 80/20 or AlSi 12 is applied between the bearing body and the liner. The bonding layer is spray deposited onto the bearing body and the liner is spray deposited onto the bonding layer. The liner is most porous at the bonding layer interface with decreasing porosity toward the bearing surface. The bonding layer may be flame sprayed or applied in powder form and fused. Similarly, the liner may be flame sprayed or applied in powder form and fused.

Abstract: A self adjusting bearing includes a load bearing having a cylindrical bore for carrying a rotating shaft. The load bearing is mounted for pivoting about an axis which is transverse to and intersects a longitudinal axis of the bore. The load bearing is supported by a pair of housings each of which carries a pivot bearing. A journal projecting radially from the load bearing engages the pivot bearing and an electrically insulating bushing is positioned between the housing and the pivot bearing to electrically isolate the main bearing from the housing. In an alternate embodiment, the insulating bushing is positioned between the load bearing journal and the pivot bushing so that the pivot bushing is also electrically isolated from the load bearing.

Abstract: A drive system for a tracked vehicle includes an engine carried in an engine housing and a transmission carried in a transmission housing. The axes of rotation of an engine output shaft, a drive transmission input and drive transmission output shaft are parallel to each other. Drivingly interconnecting the engine output shaft and the transmission input is a transfer gear carried in a transfer housing. The transfer housing is rigidly connected to the engine housing and drivingly engages the transmission input through a rotational coupling which permits radial and skew angular offsets between an axis of rotation of the transfer gear output and the axis of rotation of the transmission input to accommodate dimensional variation in the drive system components from ideal specified dimensions without stress.

Abstract: A spherical bearing with selectable electrical conductivity includes a bearing body having a spherical supporting surface, a layer of electrically insulating material and a housing having a concave spherical seating surface which form a ball joint having a center around which the bearing body may swivel relative to the housing when the housing is not clamped against the insulating layer and bearing body with the force required for operation of the bearing. A first positioning pin of electrically conductive material projects radially through the insulating layer and into a recess formed in the housing. Electrical connection between the housing and the bearing body is provided by a compression spring which bears against the recess and the first positioning pin. A second positioning pin of electrically insulating material may be selected in lieu of the first positioning pin and spring to provide a bearing configuration wherein the body is insulated from the housing.

Abstract: A bearing system for a wave generator includes at least two laterally positioned rolling discs each of which is supported eccentrically through an eccentric ring and an intermediate bearing. The eccentric rings are frictionally clamped to each other with one of the rings being adjustable relative to the other to provide eccentricity. The exterior faces of the discs roll against a flexible ring. Axial movement of the flexible ring relative to the rolling discs is precluded through the use of collars or clips which radially project from the rolling discs. The axial end faces of the flexible ring sealingly engage the interior faces of the collars.

Abstract: An electric motor drives via differential gear arrangement the track-driving wheels of the tracks of a full-track vehicle. The steering of the full-track vehicle takes place through a further electric motor, through which, depending on the travel direction of the full-track vehicle, a rotational speed can be superimposed on the differential gear arrangement with different rotational speeds. The current supply of the drive motor and of the steering motor occurs via a control and regulating equipment, as a function of adjustments of a drive member and of a steering member, from an electric generator which is driven by a diesel engine.

Abstract: A drive system includes a vehicle propulsion drive having a speed change gear box which drives tracks through a pair of planetary gears and a steering drive having a pair of variable hydrostatic drives. The hydrostatic drives engage a neutral shaft which superimposes rotation on the planetary gears to provide steering control for the tracks. The neutral shaft is separable into two segments. A differental reversing gear may be employed to selectively couple the neutral shaft segments. When the vehicle travels at high speed, the neutral shaft segments are coupled for unitary rotation. At low vehicle speeds, the propulsion drive is blocked and the neutral shaft segments are uncoupled so that both propulsion and steering are provided through the hydrostatic drives.

Abstract: A planetary drive containing two gear wheels with differing numbers of teeth and a radially flexible planetary wheel in engagement with these gear wheels. The planetary wheel has internal teeth and external teeth and is arranged at least partially in an annular gap between a hollow wheel and a sun wheel. The planetary wheel is forced by a cam element into the gaps between the teeth of the gear wheels in engagement zones. There are four engagement zones distributed around the circumference of the planetary wheel in which the teeth of the planetary wheel engage either the hollow wheel or the sun wheel. A roller bearing is provided between the cam element and the planetary wheel. The drive has a short axial structural length and a low manufacturing cost, assures uniform loading of the gear teeth, and enables the reduction ratio to be selectively predetermined throughout a large range.

Abstract: An engine (4) of a drive system (2) is adjusted and controlled by a main controller (24). When the main controller (24) breaks down, the operation of the engine can still be continued as emergency operation with an emergency controller (26). However, the controlling functions of the latter are not as optimum as those of the main controller (24). This functional deficiency of the emergency controller (26) is compensated for at least partly by an emergency program of an electronic transmission control device (28). To compensate for the functional deficiency of the emergency controller (26), the transmission control device (28) appropriately controls or regulates a transmission unit (6, 8, 10) of the drive system (2), which comprises a hydrodynamic torque converter (8) with a bridging clutch (10) that can bridge the latter, and a gear-shift mechanism (6).
