Abstract:
Ein Ausgleichsgetriebe für eine Windkraftanlage weist ein Getriebe (7) mit drei An- bzw. Abtrieben auf, wobei ein Antrieb mit dem Rotor (3) der Windkraftanlage verbunden ist, der erste Abtrieb mit einem Generator (11) und der zweite Abtrieb mit der Antriebswelle eines stufenlos regelbaren Getriebes (12), dessen Abtriebswelle mit dem generatorseitigen Abtrieb des Getriebes (7) verbunden ist. Die Antriebswelle des stufenlos regelbaren Getriebes (12) ist über ein Verstellgetriebe (15) mit der Abtriebswelle des Getriebes (7) verbunden.
Abstract:
A pair of concentrically mounted drive shafts (820, 840) are rotatable with respect to one another. Each drive shaft engages and drives at least one endless chain upon which lugs are mountable. A driven power shaft (860) directly drives one (820) of the drive shafts. The other drive shaft has a coaxially-mounted gear wheel (850) that intermeshes with a pinion wheel (870) that is rotatable and is interconnected with the driven power shaft such that when the pinion wheel is inhibited rotating power is delivered from the driven power shaft through the locked pinion gear to the gear wheel and drive shaft (840) affixed thereto.
Abstract:
This invention is concerned with improvements to a ledger for a rod-making machine of the type comprising a rod supporting part (14, 16) which is pivotally mounted on two linear motion devices (10; 12) each comprising a fixed gear (A), a first orbiting gear (B) which is preferably smaller than the fixed gear, and a pair of connected coaxial gears (C and D) of different diameter which also orbit about the axis of the fixed gear and which mesh respectively with the fixed gear and first orbiting gear (B), such that the effective gear ratio between the fixed gear (A) and the first orbiting gear (B) via the other two gears is 2:1, the rod supporting part being pivotally connected to the first orbiting gear (B) or to a crank connected thereto. According to the main improvement, an assembly including gears (B, C and D) and parts carrying them at appropriate positions is arranged to be readily replaceable to achieve a rod length change.
Abstract:
In an electrotatographic printer and/or copier, toner images are transferred from the outer surface of a rotating image process drum (1) to a receiver sheet carried on the outersurface of a rotating trnsfer drum (5) as the respective drum surfaces pass through a transfer zone defined by a nip between the drums. To assure precise registration of the transferred toner image with a desired portion of the receiver sheet, position control apparatus (50) is provided for adjusting the angular position of the transfer drum relative to that of the process drum (1) as the transfer drum (5) rotates to present the receiver sheet to the image transfer zone. Such apparatus responds to a control signal representing variations, from nominal, in the position of the toner image on the process drum (1) and/or in the position of the receiver sheet on the transfer drum (5). The position control apparatus (50) of the invention is particularly useful in color electrostatographic systems for precisely registering multiple color separation images on a receiver sheet.

Abstract:
A differential gear for a wind power plant, comprises a gearbox (7) with three inputs and outputs, wherein one input is connected to the rotor (3) of the wind power plant, the first output is connected to a generator (11) and the second output is connected to the input shaft of a continuously variable gearbox (12), the output shaft of which is connected to the generator side output of the gearbox (7). The input shaft of the continuously variable gearbox (12) is connected to the output shaft of the gearbox (7) by means of a variable gearbox (15).
Abstract:
An example method of controlling performance of gearbox of a gas turbine engine includes establishing a gear characteristic of a plurality of double helical gears each disposed about a respective axis in a gearbox. Performance of the plurality of double helical gears is controlled by selecting a circumferential offset distance between a first plurality of gear teeth spaced apart from a second plurality of gear teeth on each of the plurality of double helical gears in response to the established gear characteristic.
