A gear box has a clutch comprising a hub and a coupling, each having drive portions that are movable between engaged and disengaged positions. In the engaged position, the hub and coupling drive portions are engaged in a manner to allow torque to be transmitted between the hub and the coupling. In the disengaged position, the hub and coupling drive portions are spaced apart in a manner to prevent torque from being transmitted between the hub and the coupling. The clutch has an actuator that moves the hub and coupling drive portions between the engaged and disengaged positions. In moving the hub and coupling drive portions to the engaged position, the actuator is driven by spring pressure. In moving the hub and coupling drive portions to the disengaged position, the actuator is driven by hydraulic pressure supplied against the actuator sufficient to overcome the spring pressure.


A roller bearing cage has a cage element (20) adapted for retaining the generally cylindrically shaped rollers (30) and allowing the rollers to be rollable therein. The cage element includes a main portion (22) having a plurality of pockets (28), an outward flange portion (24) extending outwardly in a radial direction and an inward flange portion (26) extending outwardly in the radial direction. The outward flange portion (24) is formed on a side edge of the main portion and the inward flange portion (26) is formed on an opposite side edge portion thereof. The main portion (22) defines the smallest diameter of the bearing cage and is less than the roller pitch diameter (D4). The outward flange portion may also include an outward flange guide surface for guiding barrel-shaped rollers. The guide surface is cylindrical in shape and adjacent each pocket. The guide surface is adapted to abut an axial end of the rollers.


An electric machine has a stator that comprises a plurality of laminations with teeth and cooling apertures about a central opening. When the laminations are stacked to form the stator core, the teeth of adjacent laminations cooperate to form slots disposed circumferentially about the central opening that are configured to receive a plurality of stator windings, and the cooling apertures angularly spaced about the central opening cooperate to form cooling manifolds that extend along a length of the stator core. A portion of the laminations has their cooling apertures offset from other laminations in the stack in a manner to create a plurality of flow paths transverse to the manifolds. The transverse flow paths extend angularly between laminations and adjacent manifolds. A header assembly directs flow into and out of the stator core.


A system and method for mounting a bearing assembly on a shaft includes an internal flange, external flange, and a sleeve. The internal flange is securable to the bearing assembly and has a displacement pin extending outward that defines an initial position of the bearing assembly relative to the shaft. The external flange is secured to the internal flange via fasteners passing through elongated holes. The external flange has an opening configured to receive the displacement pin. The external flange may be rotated when coupled to the internal flange with the fasteners between a first position where the external flange opening is not in register with the displacement pin and a second position where the external flange opening is in register with the displacement pin. A sleeve has a tapered outside diameter and is engageable with the external flange.

A method of mounting a motor to a gearbox includes positioning a coupling along an input shaft of the gearbox from a starting position to a first alignment position. In the starting position, the coupling drivingly engages a greater portion of the gearbox input shaft than in the first alignment position. In the first alignment position, the coupling operatively contacts the motor output shaft. Another step includes rotating the coupling so that the coupling aligns with the motor output shaft. Another step includes axially positioning the coupling at a second alignment position such that the coupling drivingly engages both the motor output and the gearbox input shafts. Another step includes positioning the motor to allow mounting of the motor on the gearbox with the coupling at a third alignment position drivingly engaging a greater portion of the motor output and the gearbox input shafts than in the second alignment position.

A lubrication system for a gear box has a backing member. The backing member is configured to allow mounting of a plurality of lubrication components on the backing member. One of the lubrication components comprises a pump configured to pressurize lubricating oil for the lubrication system. The pump has a suction and discharge. The pump suction is removably connectable to the gear box and the pump discharge is removably connectable to piping that is configured to communicate with the gear box. The backing member has a lifting mount arranged along its length and width that corresponds to a center of gravity of the backing member with the lubrication components mounted thereto. The lubrication components are modular and may be replaced and installed as necessary on the backing member. Multiple like lubrication systems may be provided, and removed and installed on the gear box as needed for maintenance.


A method comprises providing a line-start synchronous motor. The motor has a stator, a rotor core disposed within the stator, and a motor shaft. In accordance with a step of the method, a coupling for coupling a load to the motor is provided. The coupling has a motor shaft attachment portion configured to provide substantially concentric contact around the shaft at the end of the motor shaft. The coupling has a load attachment portion configured to operatively connect to a load. In accordance with a step of the method, a load is coupled to the motor with the coupling, and driven from start to at least near synchronous speed during steady state operation of the motor with a load coupled thereto. The motor shaft attachment portion may comprise a bushing assembly with matching and opposed tapered surfaces that cooperate to secure the motor shaft attachment portion around the motor shaft.

A gear box housing has a hollow interior configured to contain a gear train. The gear train has a shaft extending from the housing hollow interior though an opening. The housing has a sump in the housing hollow interior for lubricating oil used for lubricating at least some portions of the gear train. A grease seal adjacent to the opening of housing is configured to seal around the shaft. The grease seal has a fill line that extends from an injection port located exterior of the housing, through a structural member of housing into the interior of the housing, and through the oil sump to the grease seal. The grease seal has a discharge line that extends from the grease seal, through the oil sump, and through a structural member of the housing to the exterior of the housing to a discharge port located exterior of the housing.

A drive system powers a six-phase AC induction motor having a plurality of poles and a stator with a plurality of teeth where the number of teeth divided by six times the number of poles equals an integer number. The stator core has first and second groups of three-phase stator windings. The second group of three-phase windings is separated spatially by 30 electrical degrees from the first group. A first power supply is connectable to the first group of three-phase windings. A second power supply is connectable to the second group of three-phase windings. The second power supply provides power to the second group of three-phase windings that is shifted by 30 electrical degrees in time with respect to the first power supply. The first and second power supplies receive signals from identical pulse width modulator generators. The respective first and second pulse width modulator generators receive commands from one controller.


A magnetic coupling for transferring rotational motion from a prime mover to a load includes reference marks calibrated to indicate torque applied to the coupling during operation. A light source providing intermittent light flashes permits a user to visibly discern the relative rotational position of the reference marks to one another, and thereby determine the torque applied to the coupling.
