Patent number: 9932969Abstract: Disclosed is a wind turbine, which comprises a rotatable structure being coupled to a hub of the wind turbine and to a generator rotor comprising a brake disc, a stationary structure being coupled to a generator stator and comprising a stator frame and a safety bearing element. The rotatable structure is rotatably coupled to the stationary structure, wherein the stator frame comprises a brake mounting section to which a calliper brake is mountable such that the brake disc is breakable by the mounted calliper brake. The safety bearing element is mounted to the brake mounting section such that the brake disc is in slidable contact with the safety bearing element if a distance between the brake mounting section and the brake disc is reduced below a predetermined reference value.Type: GrantFiled: April 26, 2016Date of Patent: April 3, 2018Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Uffe Eriksen, Claus Johansen, Jens Anton Agerskov Veng

Patent number: 8221102Abstract: A hydraulic machine has a gear wheel (2) with outwardly extending teeth and a gear ring (4) with inwardly extending teeth formed by rollers each of which is supported in a pocket (8) in the gear ring, and pressurized spaces are formed between the gear wheel and the inwardly extending teeth. To keep the wear of the machine small, each pocket (8) has at least two different radii (R1, R2, Rn) whereby a radius (R2, Rn) at a smaller displacement from the edge (12) of the pocket is larger than a radius (R1) at a larger displacement from the same edge (12) of the pocket (8).Type: GrantFiled: February 26, 2010Date of Patent: July 17, 2012Assignee: Sauer-Danfoss ApsInventors: Joergen Pedersen, Hans Christian Petersen, Claus Johansen

Patent number: 7407374Abstract: The invention concerns a hydraulic machine with a toothed set comprising a toothed ring with an inner toothing, whose circumferential surface extends in parallel with its axis, and a gear wheel (3) with an outer toothing, whose circumferential surface (24) extends in parallel with its axis, at least one tooth flank having an edge as an axial end of a section, which is located between the circumferential surface and a surface directed radially inwards. It is endeavored to reduce the wear. For this purpose it is ensured that in the radial direction an edge (22, 23) ends so as to be offset inwards in relation to the circumferential surface (24).Type: GrantFiled: September 27, 2005Date of Patent: August 5, 2008Assignee: Sauer-Danfoss ApsInventors: René Andersen, Kim René Hansen, Claus Johansen

Publication number: 20050180873Abstract: The invention concerns a hydraulic machine with a set of teeth, having a toothed ring with an inner toothing and a gear wheel with an outer toothing, the gear wheel rotating and orbiting in the toothed ring, the inner toothing and the outer toothing touching each other in contact areas, thus separating pressure chambers, and with a valve arrangement controlling a connection between a connection arrangement having a high pressure connection and a low pressure connection, and the pressure chambers. It is endeavoured to achieve a stable operation, particularly with low speeds. For this purpose, each contact area is provided with an opening, which, at the time when a pressure chamber reaches an extreme value of its volume, produces a short-circuiting with the neighbouring pressure chamber.Type: ApplicationFiled: February 27, 2003Publication date: August 18, 2005Applicant: Sauer-Danfoss ApsInventors: Kim Hansen, Claus Johansen, Rene Andersen

Patent number: 6739849Abstract: A gerotor motor has a housing located adjacent a port plate. The housing has two fluid chambers on opposite sides of a disc valve. The disc valve is in sealing surface engagement with the port plate to prevent fluid from moving between the fluid chambers. The valve assembly has forward and rearward sides and has substantially equal volumes of material removed therefrom so as to balance the port plate against any torsional forces imposed on the valve assembly which might otherwise deflect the valve assembly to interfere with its sealing relationship with the port plate.Type: GrantFiled: January 9, 2003Date of Patent: May 25, 2004Assignee: Sauer-Danfoss (Nordborg) A/SInventors: Kim Rene Hansen, Claus Johansen, Rene Andersen

Patent number: 6739848Abstract: A hydraulic motor of the disc valve type has a disc valve with a plurality of commutation slots that can sequentially register with ports in a port plate as the disc valve is rotated with respect to the port plate. The commutation slots have a geometrical configuration that is complimentary in shape to a portion of the geometric configuration of the ports in the port plate to reduce the resistance to fluid flow through the ports and the slots when the complimentary shapes move into or from superimposed registering positions.Type: GrantFiled: January 9, 2003Date of Patent: May 25, 2004Assignee: Sauer-Danfoss (Nordborg) A/SInventors: Kim Rene Hansen, Claus Johansen, Rene Andersen

Patent number: 6427722Abstract: The invention concerns a rotary slide set for a hydraulic steering arrangement with an outer rotary slide and an inner rotary slide arranged in the outer rotary slide, and having in its surface tank grooves, which are, at least in predetermined rotary positions, connected with a low pressure connection, and at least one through-opening in its wall, each overlapping, at least partly, a tank groove. In a rotary slide set of this kind it is desired to avoid jamming between the inner and the outer rotary slides. For this purpose, surface recesses have been made at the remaining tank grooves to serve as balancing areas.Type: GrantFiled: May 23, 2001Date of Patent: August 6, 2002Assignee: Danfoss Fluid Power A/SInventors: Claus Johansen, Tage Christiansen

Patent number: 6264567Abstract: The invention concerns a machine arrangement with a first machine having a first rotation connection, a second machine having a second rotation connection, and a shaft for transmission of a torque, the shaft being unrotatably connected with both rotation connections. In this connection it is desired to minimize the effects of alignment errors on mounting the two motors. For this purpose the shaft (5) has, at least in one end, an external toothing (6) engaging with an internal toothing (8, 9) of the machine at this end, said external toothing permitting a swivel movement of the shaft (5), the teeth (10) of said external toothing (6) having concavely extending tooth flanks (11, 12), whose axial ends (15, 16) are less curved than their area of the axial centre.Type: GrantFiled: November 5, 1999Date of Patent: July 24, 2001Assignee: Danfoss A/SInventors: Finn Lyhne, Tom Tychsen, Hans Christian Petersen, Claus Johansen
