A modular gearbox assembly for a wind turbine having improved up-tower serviceability includes a low-speed gear stage module, a separate, intermediate-speed gear stage module adjacent to the low-speed gear stage module, and a separate high-speed gear stage module adjacent to the intermediate-speed gear stage module. The gearbox assembly also includes a first flange removably connecting the intermediate and high-speed gear stage modules and a second flange removably connecting the intermediate and low-speed gear stage modules. Thus, the low-speed gear stage module converts a low-speed, high torque input from a rotor shaft of the wind turbine to a high-speed, low torque output for a generator of the wind turbine via the intermediate and high-speed gear stage modules. In addition, the first and second flanges allow for easy disassembly of the gear stage modules such that the various stages can be easily repaired, replaced, and/or inspected.

A hybrid powertrain includes an output shaft, a combustion power section for providing a first torque, an electric power section for providing a second torque, and an output transmission for transmitting the first torque between the combustion power section and the output shaft and transmitting the second torque between the electric power section and the output shaft. The combustion power section includes an internal combustion engine with a combustion shaft for outputting the first torque, a generator with a generator shaft for converting the first torque into electric energy, and a variable belt transmission for variably translating the first torque. The belt transmission includes a combustion-side cone pulley pair with a first axially movable pulley arranged on a generator shaft side, an output-side cone pulley pair with a second axially movable pulley, and a belt for variably torque-transmittingly connecting the combustion-side cone pulley pair to the output-side cone pulley pair.

A drive train (10) for driving a motor vehicle has a combustion engine (12) for providing purely mechanical drive for the motor vehicle. A transmission (16) can be coupled to the combustion engine (12) via a shaft unit (14) for transmitting torque between the motor vehicle transmission (16) and the combustion engine (12). A reserve volume (18) is between the combustion engine (12) and the motor vehicle transmission (16) and is penetrated by the shaft unit (14). The reserve volume (18) can accommodate a high-voltage electric machine for purely electric drive of the motor vehicle or a low-voltage electric machine (32) for applying an electrically generated assistance torque to the motor vehicle transmission (16). As a result, a hybrid functionality can be made available to an at least limited degree, with the result that a cost-effective drive train (10) configured for a hybrid motor vehicle is made possible.

The invention relates to a transmission, to a transmission housing, to a driving member mounted rotatably in the transmission housing, to an output member mounted rotatably in the transmission housing and to at least one speed-changing transmission stage which couples the output member to the driving member and has a torque-supporting member, wherein the driving member together with the output member and the torque-supporting member forms a preassembled assembly in which the torque-supporting member is mounted rotatably on the transmission housing by means of a transmission-stage rolling bearing device and has a toothing which is in engagement with a driving pinion mounted rotatably in the transmission housing. The invention also relates to an electric driving device and to an industrial robot having at least one such transmission.

A gearbox assembly for a twin-screw extruder comprises a speed change gearbox for adjusting a screw shaft speed of two screw shafts of the twin-screw extruder, a distribution gearbox allowing the screw shafts to be coupled thereto, and a speed reduction gearbox. The speed change gearbox and the speed reduction gearbox are configured such as to be separable from each other, wherein the speed change gearbox is arranged at a driving end while the speed reduction gearbox couples the speed change gearbox to the distribution gearbox. Due to the fact that the speed change gearbox is configured as an individual gearbox unit arranged at the driving end, an adjustment of the screw shaft speed is easily possible by replacing the speed change gearbox. As a result, a high flexibility and productivity are obtained in the operation of the twin-screw extruder.

A control unit is provided, in particular a transmission control unit, which is designed to be attached to an outer side or to an inner side of a housing, in particular to a transmission housing, wherein the control unit comprises a circuit board as well as at least one plug which is arranged on the circuit board and whose pins are connected to corresponding conducting paths of the circuit board, which is arranged in such a way that it reaches into an opening within the housing and to produce an electrical and/or signal connection between the outer side and the inner side of the housing via conducting paths that are arranged on the circuit board, wherein an overmolding is enclosing at least the circuit board and the plug(s).

An oil pump plate for operatively coupling an oil pump within a gearbox casing is provided, which allows installing and/or uninstalling an in-line filter for the oil pump without having to modify the gearbox casing.

A planetary transmission for transmitting drive power to a work machine, comprising a plurality of planetary gearwheels, a plurality of planetary shafts and at least one planetary carrier, the planetary gearwheels being arranged in each case rotatably on one of the planetary shafts, and the planetary shafts being fastened in each case to the planetary carrier, characterized in that the planetary carrier is configured for a releasable connection to a work machine shaft.

A nesting structure supports a differential case. The nesting structure includes a first support structure that supports the differential case. The nesting structure includes a second support structure spaced apart from the first support structure to define a support opening. The support opening receives a first shim and establishes a first orientation between the first shim and the differential case in which the first shim is non-parallel with respect to a first bearing surface of the differential case.
