Abstract: Bearing, characterized in that it is composed of two bearings which are configured such that the composed bearing can be loaded in the radial direction and in both axial directions, whereby these two bearings fit in an outer bush which is provided with an axial stop.

Abstract: A gearbox for a wind turbine includes a ring wheel unit provided in a housing; a driving shaft designed to be coupled to the rotor of the wind turbine and a single main bearing or a pair of main bearings which rotatably support the driving shaft in the housing. The ring wheel unit is formed of a sun wheel, a planet wheel, ring wheel which is fixed to the housing in a non-rotating manner and a planet carrier which is rigidly connected to the driving shaft. An additional bearing rotatably supports the planet carrier or the driving shaft relative to the housing. Between the part of the housing having the main bearing or the main bearings and the part of the housing with the additional bearing and the ring wheel, an elastic part is provided with relative torsional stiffness, yet relatively flexible to loads in the axial and/or radial direction.

Abstract: A structural connector for providing a structural interconnection between the housing of a gear unit and the housing of an electric motor, the structural connector being of a modular type including a base member adapted for connection to at least one of the housing of an electric motor and the housing of a gear unit, and at least two side wall members, the side wall members having a motor end adapted for connection to one of an electric motor housing and the base member and a gear end adapted for connection to a gear unit housing, the side wall members lying at least in substantial part in a plane inclined at an angle of at least 60 degrees relative to a plane containing at least a part of the base member, and the side wall members being spaced apart by connection to an interposed housing.

Abstract: A method for manufacturing a coupling of the type which mainly consists of a male part and a female part, which are respectively provided with an axially extending outer toothing and a complementary inner toothing, whereby both parts can be axially shifted in relation to each other with their toothings, wherein the method at least consists in making the toothing of one of the parts cylindrical and in realizing the grooves between the outer toothings of the male part with a tool with which a female cylindrical shape can be made, such as for example a drill or a cutter

Abstract: A planetary gear wheel construction with one or several planet wheels which are bearing-mounted on a planet carrier, which is provided in a rotating manner in a housing, and an oil lubrication which is formed of an oil supply via a ring-shaped channel in the housing formed of a ring-shaped groove and a distribution element turning along with the planet carrier which is held in said groove such that it can rotate, and which is provided with a passage to connect said oil channel to an oil channel in the planet carrier which opens at a planet wheel, wherein the distribution element is coupled to the planet carrier by means of a loose connection which makes it possible to transmit the rotational movement of the planet carrier to the distribution element, and in that the oil channel in the planet carrier is connected to the passage in the distribution element by means of a flexible or moving oil pipe.
