A disclosed submersible pump apparatus includes a three-dimensional frame, a pump housing, a drive shaft, an impeller, and first and second motors. The impeller is mounted on the driveshaft within the pump housing and is driven by one or both of the motors. The first motor is connected to a first end of the drive shaft and the second motor connected a second end of the drive shaft. The first and second motors are hydraulic motors and in a first configuration, the first and second motors are configured to cooperatively rotate the drive shaft with hydraulic fluid supplied to and removed from the first and second motors using a parallel fluidic connection. In a second configuration, only one of the motors has a drive gear and drives the drive shaft while the second motor does not have a drive gear and acts as a frictionless bearing supporting the drive shaft.

Claimed is a splint joint for a drive shaft including a receptacle with an interior and with a drive shaft extending from the receptacle. A bushing having a bushing body is inserted into the receptacle interior and the receptacle and bushing are immovably affixed in resistance to rotation by friction. The bushing is affixed to a bushing ring with the combined bushing and bushing ring inserted into the receptacle. Machine bolts draw bushing and bushing ring together. The bushing and the bushing ring each have a single split and both have a spring function. As the bushing and bushing ring are drawn together the bushing ring is expanded into friction contact with the bushing receptacle interior and the bushing is compressed into friction contact with the bushing ring. Push bolts allow the bushing to be urged away from the bushing ring.

The Drive Shaft Splint Joint is a receptacle with a tapered interior and with a drive shaft extending from the receptacle. A bushing having a tapered body is inserted into the receptacle tapered interior and the receptacle and bushing are immovably affixed with bolts. The bushing has a keyed aperture which receives a keyway drive shaft. Push bolts allow the bushing to be urged away from the receptacle allowing the drive shaft to be disassembled.

A journal receptacle for a wobbler connection, in particular for the rotationally secure connection of a drive shaft, such as an articulated shaft, to a roll of a rolling mill. A wobbler hub has a receiving opening that extends in an axial direction of the wobbler hub, for the positive-locking reception of a roll journal. The receiving opening has an inner surface, extending in the axial direction and over the periphery and at least one torque transmission surface. The latter is clad at least partially with at least one wearing plate. The at least one wearing plate is held in a positive-locking manner on the torque transmission surface by at least one clamping piece, which extends in the axial direction on the torque transmission surface and which is connected to the torque transmission surface by a connecting device.

A vehicle has a transfer case that is configured to receive power from a transmission, and transfer the power to one or both of a front axle and a rear axle. The transfer case has an output, such as an output rod, that delivers the power to a differential on one of the axles. A driveshaft has a single constant-velocity joint thereon. A first shaft of the driveshaft is directly connected to the output of the transfer case by a fixed connection, such as a spline connection, that inhibits axial slipping. The first shaft is connected on its other end to the constant-velocity joint. A second shaft of the driveshaft is connects to the constant-velocity joint to the differential. The driveshaft can also have a clamp at the splint to inhibit axial slipping at the spline connection.

Described herein is an apparatus for securing a coupled element onto a shaft. More particularly, an apparatus is described that provides a tight fitment of a coupled element such as a piston onto a shaft capable of handling high pressure forces without relative movement of the coupled components and, which may minimise parts needed, provide optimal material utilisation, and avoid the requirement for fasteners.
