Publication number: 20170059031Abstract: A lubricating system has been disclosed for gear mechanisms or generators, in particular for gear mechanisms of wind power plants, which lubricating system permits a switchover between dry sump lubrication and wet sump lubrication. This takes place by way of a delivery device which increases the pressure in a lubricant tank selectively or in an emergency, for example a power outage, and presses a lubricant back into an oil sump in the gear mechanism, whereupon a lubricant level is increased there and wet sump lubrication is realized. The delivery device can have a compressor. Said compressor can charge a pressure accumulator via a non-return valve or can increase the pressure in the lubricant tank directly. The delivery device can consist of hydraulic, pneumatic or else electrical components. If it is pneumatic, it can be separated from the hydraulic lubricating system via an elbow.Type: ApplicationFiled: June 10, 2014Publication date: March 2, 2017Inventors: Ibrahim Doertoluk, Klaus Ulrich, Bernd Schnurr, Matthias Oppelt, Udo Froehlich

Patent number: 9091369Abstract: A control device has a control drive for operating a valve or some other apparatus, for example an adjustment device for the pitch angle of a wind rotor, by means of a control element. This control drive is associated with an emergency operating device, via which the control element can be reset in the event of a disturbance, essentially independently of the operation of the control drive. This emergency operating device has an energy store, whose stored energy can be released for resetting. The emergency operating device has a piston, on one side of which the energy store acts and on the other side of which a pressure in a pressure area acts, which pressure area can be connected via a switching valve to a tank or the like, in order to release the energy stored in the energy store. In this case, the piston is designed such that it moves the control element in a resetting direction when the pressure in the pressure is relieved.Type: GrantFiled: July 20, 2009Date of Patent: July 28, 2015Assignee: Robert Bosch GmbHInventors: Udo Froehlich, Ibrahim Doertoluk, Bernd Schnurr, Richard Tauber

Patent number: 9048768Abstract: A stationary energy generation plant includes a control device that serves to control current and energy flow. The energy generation plant includes at least one mechanically driven rotor and a generator mechanically coupled to the rotor. To this end, power electronics operationally connected to the generator enable variable energy flow from the rotor through the generator and the power electronics to a load. In order to compensate for vibrational loads on the generator side, at least one current control is made possible by means of a first intermediate circuit storage of the power electronics. In order to compensate for mechanical vibrational loads and transients of a drivetrain, an energy flow control is provided by means of at least one additional second intermediate circuit storage disposed in the power electronics and having a multiple of the storage capacity of the first intermediate circuit storage.Type: GrantFiled: November 25, 2009Date of Patent: June 2, 2015Assignee: Robert Bosch GmbHInventors: Lothar Schindele, Boris Buchtala, Anton Paweletz, Bernd Schnurr, Andreas Vath

Patent number: 7566981Abstract: An actuating drive for a rotor blade in a wind power installation is provided with an electric motor and a frequency converter which has a rectifier that is to be fed from a power supply system, a link connected to the rectifier, and a d.c.-to-a.c. inverter for feeding the motor, the link carrying a specified nominal operating voltage in a network-fed normal operation of the frequency converter. Furthermore, an auxiliary energy supply device is provided that is connected to the link. The auxiliary energy supply device includes and energy store which makes available a support voltage that amounts to less than 80% of the nominal operating voltage of the link. A diode is connected between the energy store and the link, and is arranged, with regard to its forward direction, in such a way that it feeds a support voltage from the energy store into the link if the link voltage falls below the support voltage.Type: GrantFiled: June 29, 2006Date of Patent: July 28, 2009Assignee: Bosch Rexroth AGInventors: Steffen Kunkel, Karl-Günter Herrmann, Michael Hörning, Berno Kobelbauer, Jörg Dantlgraber, Stephan Becker, Gunther Neidlein, Bernd Schnurr

Publication number: 20090164052Abstract: The present invention relates to an actuator 10 for a movably situated device, in particular a device for joining stacked adherends 7, in particular a pair of welding tongs. The object of the present invention is to realize a position-dependent control of a device, the position of which may be changed, while minimizing the additional effort or outlay required. The present invention solves this problem by integrating a measuring means 2 for detecting at least one position-dependent measured quantity in the actuator, it also being possible to derive the position of actuator 10 from the measured quantity. The measuring means is enclosed in actuator 10. This has the advantage that additional interference edges on the device on which the actuator is located may be avoided, and the position-dependent signal may be transmitted to higher-order controller 4 easily along with other signals that are transmitted by the actuator anyway.Type: ApplicationFiled: December 19, 2008Publication date: June 25, 2009Inventors: Ibrahim Doertoluk, Bernd Schnurr

Publication number: 20090158869Abstract: In practical application, it often happens that a large number of motion sensors and control mechanisms is required in order to carry out controlled movements, e.g., of welding tongs. The object of the present invention is to provide a solution for controlling the movement of a pair of welding tongs in the most efficient and economical manner possible with a minimum of electrical and mechanical expenditure. This object is attained by the present invention by using mechanical displacement-limiting means that limit a swiveling motion if it should occur. The advantage is the robust design and elimination of electronics and sensor systems, which are susceptible to interference.Type: ApplicationFiled: December 17, 2008Publication date: June 25, 2009Inventors: Ibrahim Doertoluk, Peter Schuh, Emil Hanauer, Bernd Schnurr
