A wind turbine gear mechanism with a planetary gear stage arranged on the drive input side and with first and second spur gear stages arranged, in a gear mechanism housing, downstream of the planetary gear stage. The first spur gear stage rotationally and functionally connects a sun gear shaft of the planetary gear stage to an intermediate shaft, the second spur gear stage rotationally and functionally connects the intermediate shaft to a drive output shaft, and only one intermediate shaft is provided. In this case, the gear mechanism housing has a separation joint along which the gear mechanism housing can be divided into a main housing portion and a housing cover in such manner that a separation joint plane passes through the central axis of the intermediate shaft and the separation joint plane extends a distance away from the central axis of the sun gear shaft.

Wind turbine gear mechanism

An adjusting system for camshafts of an internal combustion engine having an emergency running function, comprising a phase shifter gearing with an input drive element driven by a crankshaft of an internal combustion engine, an output drive element which drives a camshaft of the internal combustion engine, and an actuating element, by means of which a relative rotation between the drive input element and the drive output element can be realized by means of a device for imparting a braking torque, which is variable for normal operation, to the actuating element. In the event of failure of the device and/or control thereof, an emergency running setting of the camshaft can be attained and maintained as a result of braking or respectively, arresting the actuating element.

Adjusting system for camshafts of an internal combustion engine

An arrangement for mounting and fixing a planetary gear system () onto a camshaft (). The planetary gear system comprises a planetary carrier () that forms the drive input of the camshaft (), with planetary gears () mounted on planetary bolts (). A ring gear () is rotationally fixedly connected to the camshaft (), and a sun gear () is connected with a sun shaft (). The ring gear () is arranged at the end of and coaxially with the camshaft () and is rotationally fixedly connected to the camshaft () by eccentrically arranged fixing elements ().
