Patent number: 9803657Abstract: A hydraulic adjusting device, in particular for use in a power plant and/or a wind power plant, includes a double-acting adjusting cylinder that has an adjusting function for a working operation and for a special operation. The double-acting adjusting cylinder is configured to be pressurized with a working pressure medium. In order to satisfy the adjusting function in the special operation, the double-acting adjusting cylinder is further configured to be connected to a pressure medium reservoir that has a pressurized gas isolated from the working pressure medium. The adjusting cylinder has a working chamber configured for the adjusting function of the special operation, the piston area of which is coupled to a piston arrangement of the adjusting cylinder that is configured for the working operation or is configured to be coupled to the piston arrangement.Type: GrantFiled: May 31, 2013Date of Patent: October 31, 2017Assignee: Robert Bosch GmbHInventors: Udo Froehlich, Sebastian Krug, Ibrahim Doertoluk

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: 9528627Abstract: A drive having an emergency closing function comprises a movable coupling device, which has an emergency spring clamped between an input-side and an output-side spring system. The emergency spring is a compression spring moved along with the coupling device. A distance of the spring systems is defined by a locking device in normal operation of the drive, wherein the emergency spring can relax for an emergency function or emergency movement of the drive after the locking device is released or unlocked. The locking device is operated or triggered hydraulically or pneumatically and/or magnetically.Type: GrantFiled: February 15, 2011Date of Patent: December 27, 2016Assignee: Robert Bosch GmbHInventors: Udo Froehlich, Richard Tauber, Ibrahim Doertoluk

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

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

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
