Abstract: In one embodiment, a drive axle, comprising: a first axle frame comprising a first pair of gears at opposing sides of one end of the first axle frame, each of the gears comprising a hole; a second axle frame comprising a second pair of gears at opposing sides of one end of the second axle frame adjacent the one end of the first axle frame, each of the gears comprising a hole, the first pair of gears intermeshing with the second pair of gears throughout an articulation range; a center frame disposed between the first and second axle frames, the first and second axle frames coupled to the center frame by plural pins disposed in the holes of the first and second pairs of gears; a driving shaft surrounded at least in part by the first axle frame and comprising a first yoke; a driven shaft surrounded at least in part by the second axle frame and comprising a second yoke; and a double cardan joint, the double cardan joint coupled to the first and second yokes, wherein the center frame surrounds at least a portion o

Abstract: In one embodiment, a system comprising: a planetary gear set configured to receive plural inputs and provide a variable output, the plural inputs comprising a first input and a second input; a motive system comprising an engine; a first clutch coupled to the motive system and configured to provide the first input; a variable speed drive system coupled to the motive system and configured to provide the second input; and an unloading system operatively coupled to the output of the planetary gear set.

Abstract: A powered square baler is operable to form a bale by compressing loose material. The powered square baler broadly includes a chassis, a plunger assembly, and a plunger drive. The chassis includes a baler frame that presents a baling chamber to receive the loose material. The plunger assembly includes a reciprocating plunger head and a pair of connecting arms attached to the plunger head. The reciprocating plunger head is slidably mounted relative to the frame and is operable to reciprocate into and out of the chamber and apply a compressive force to the loose material. The plunger drive includes a pair of planetary gear trains and a common drive shaft that powers both of the gear trains, with each gear train drivingly connected to a corresponding one of the connecting arms to cooperatively power the plunger assembly.

Abstract: In one embodiment, a system comprising an electric actuator; a mechanical shift linkage; and a spring system operably configured as a conduit of force and motion between the electric actuator and the mechanical shift linkage when the mechanical shift linkage is not constrained from movement, the spring system energized by the electric actuator when the mechanical shift linkage is constrained from movement.

Abstract: A powered square baler is operable to be powered by a prime mover to form a bale by compressing loose material. The powered square baler broadly includes a chassis, a plunger assembly, a flywheel, and a planetary gear train. The chassis includes a baler frame that presents a baling chamber to receive the loose material. The plunger assembly includes a reciprocating plunger head slidably mounted relative to the baler frame and operable to reciprocate into and out of the chamber and apply a compressive force to the loose material. The flywheel is rotatably mounted on the chassis and is operable to be driven by the prime mover. The planetary gear train is drivingly attached to the flywheel and is drivingly attached relative to the plunger assembly to transmit power between the flywheel and the plunger assembly and thereby drive the plunger head.

Abstract: A radial mixing header for use with apparatus that removes solids from a liquid by dissolved air flotation (DAF). The header comprises a par of concentric pipes circumscribed by a concentric mixing chamber having a tangential port for introduction of the recycled gas-liquid stream thereinto. The recycled stream achieves rotary and turbulent motion and mixes in a larger diameter pipe with the raw solids-containing stream which flows through a smaller diameter pipe.
