A transmission shaft (), designed particularly for a wind turbine, which is mounted by way of a fixed bearing () and at least one floating bearing (). At least one gearwheel () is fixed onto the transmission shaft () and positioned in the axial direction between the fixed bearing () and the floating bearing (). The fixed bearing () is formed by at least one roller bearing and the floating bearing () is in the form of at least one slide bearing.

Combined anti-friction and plain bearing mounting for a gearbox shaft

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

A ship propulsion () with at least a fixedly positioned transmission unit () secured to the hull () of the ship and a propulsion unit () located on the exterior of the hull. The ship propulsion () facilitates pivoting of the propulsion unit () around a control axis (), via a control device (). The control device has a control motor () and at least one control transmission (). The control transmission is designed as a reduced planetary transmission, which comprises two central gears () and a planetary gear carrier () with at least two planetary gears (), and coaxial positioned with reference to the control axis.

Controller for a ship's propulsion

A planetary gear train having planetary gears () which are rotatably mounted on a planet carrier () and are in toothed contact with an internally toothed ring gear () and a sun gear (). For a simplified, process-safe and inexpensive backlash of the planetary gears () without axial displacement of the sun gear (), the ring gear () and the planetary gears () are conically designed so that planetary gear axles () are retained in the planetary gear carrier () at an inclined angle (a) and that the planetary gears () are axially movably disposed upon and coordinated with the planetary gear axles () and the position of the planetary gears () can be adjusted within the planetary train by adjusting mechanisms for adjusting a backlash.

Planetary gear train

A planetary gear for mounting on an electromotor is proposed, in which higher efficiency is achieved by positioning a sealing element ( ) between a housing ( ) and a sun gear shaft ( ) on the input side, axially outside a receiving area ( ) for the output shaft of the electric motor, in an axial section of the sun gear shaft ( ) with an outer reduced diameter compared to the receiving area ( ).

Planetary gear for mounting on an electromotor

Proposed is a planetary drive, having a rotationally driven sun gear ( ) disposed coaxially to principal drive axis ( ), with a an internal gear ( ) affixed within housing ( B) and possessing a rotatably supported planet carrier ( ), about which a plurality of circumferentially apportioned planet gears ( ) are rotatably seated, which are in complementary tooth engagement with the sun gear ( ) and with the internal gear ( ), whereby the planet carrier ( ) forms the output drive and in common with an output side output drive shaft ( ) is supported within the housing by an axially installed inclined bearing pair, comprised of a first inclined bearing ( ) and a second inclined bearing ( ). Further proposed is that at least the first inclined bearing ( ) is affixed with its inner ring ( ) in the housing ( A) and the outer ring ( ) of the bearing is to rotate with the planet carrier ( ) and having its pressure lines ( ) forming a pressure cone, the apex ( ) of which points away from the second inclined bearing ( ).
