A drive in an agricultural machinery driveline has a drive housing (1), which forms an interior (18), and is at least partially filled with lubricant. A first shaft (4) is rotatably supported in the drive housing (1) around a longitudinal axis (13) and is guided out of the interior (18). First longitudinal teeth (8) connect, in a rotationally fast way, to a second shaft (9) via a second longitudinal teeth (10) formed to complement the first longitudinal teeth (8). One of the two shafts (4) has a...

A drive system has a drive motor with an associated current regulator. The current regulator controls the semiconductor contact elements of an electronic power stage, which is arranged downstream from the drive motor. This control is a function of a rotor-position sensor, whose rotor part is coupled to the rotor of this motor and has a number of magnetic poles corresponding to the number of poles of the drive motor. Furthermore, the current setpoint that is supplied to the current regulator is i...

A drive system for a drive wheel of a vehicle having a hub. The drive system includes a frame, a sun gear including toothing on an outer surface, a motor arranged to rotate the sun gear via an output shaft, a revolving circular, a peripheral gear including toothing on an inner surface, and planetary gears interposed between the sun gear and the peripheral gear and engaging with the toothing of the sun gear and the toothing of the peripheral gear. Each planetary gear has a shaft connecting to the...

A drive is provided with an electric motor including a rotor, a stator and a rotor shaft coupled to the rotor. The rotor shaft is coupled via a reduction to a rotatable drive, while the drive is provided with at least one measuring device designed for measuring a load applied during use via the reduction to the electric motor.

In a drive, a position and/or a speed of the drive are detected by a drive sensor. After being digitized by a feedback unit arranged on or in the drive, the position and/or the speed of the drive are transmitted to a superordinate drive control unit. At least one additional measurement quantity is detected on or in the drive by an additional sensor. The at least one additional measurement quantity is also digitized by the feedback unit before being transmitted to the superordinate drive control ...

A marine drive includes a drive shaft having an upper portion, a lower portion, and at least one waist portion between the upper and lower portions. The upper portion is adapted to be coupled to an engine crankshaft and the lower portion is adapted to be supported by bearings and drives a propulsion device through a transmission. The waist portion has a diameter of generally lesser size than the diameters of the upper and lower portions. The waist portion is tapered so that the diameter of the w...

A threaded nipple (26) at the closed end of a linear hydraulic motor (12) is received within a recess (82) in a frame member (78). Single clamp members, or individual clamp members (88), have recesses (92) that receive lower portions of the nipples (26). Bolts (94) extend through the clamp members (88) and screw into threaded openings in the frame member (78). This clamps the nipples (26) between the frame member (78) and the removable clamp members (88). End members (22) at the rod ends of the ...

A variable pulley system incorporating driver and driven pulleys in which a flange of the driver pulley has a rim to receive the belt or the like connecting the pulleys in the final drive ratio of the pulleys.

A drive system for driving accessories associated with the engine of a vehicle and controlled by the speed of the engine crankshaft, constructed such that the rpm of each accessory is substantially constant over at least the major portion of the normal vehicle operating range regardless of increase in the rpm of the engine and its crankshaft. The drive is so constructed that the input rpm to each accessory increases at substantially the same rate as the rpm of the crankshaft to a first, predeter...

Fitting yokes are coupled each by a universal joint of the trunnion type to the opposite ends of a shaft assembly biased for axial extension. Each of the fitting yokes has a sleeve inserted in a center bored portion of the universal joint with a clearance formed therebetween to permit relative angular displacement between the axis of the shaft assembly and the axis of the fitting yoke. The drive shaft therefore has a greatly reduced length in its entirety. The shaft assembly includes a splined p...
