Patent number: 9810268Abstract: The invention relates to a bearing arrangement (12) for a part to be mounted such that the part rotates about an axis, such as a cylinder, roller, drum or shaft, comprising at least one rolling bearing (23), which is accommodated in a bearing housing (27), which is mounted movably in an arrangement housing (29) in a linearly movable manner by at least one linear guide (28), and also including an actuation device (1) for effecting a linear shifting movement of the bearing housing perpendicularly to the axis between a rest position and a working position. The actuation device includes at least one prestressed spring element, which presses the bearing housing into the working position, and at least one hydraulic or pneumatic device for generating a restoring force acting counter to the spring element for moving the bearing housing into the rest position.Type: GrantFiled: May 13, 2014Date of Patent: November 7, 2017Assignee: Schaeffler Technologies AG & Co. KGInventors: Thomas Dittenhofer, Stephan Popp

Patent number: 7576464Abstract: A device for driving a cylinder (1) of a printing machine has an electric motor (3) whose rotor (14) is arranged coaxially with respect to the cylinder (1) and is firmly connected so as to rotate with the latter, and whose stator (15) is held on a frame construction (2) in which the cylinder (1) is mounted such that it can be displaced axially. The rotor (14) and the stator (15) are dimensioned and coupled to the cylinder (1) and the frame construction (2), respectively, in such a way that during any axial displacement of the cylinder (1) possible during the operation of the printing machine, the gap (16) formed between stator (15) and rotor (14) remains constant both with regard to gap width (s) and with regard to length.Type: GrantFiled: October 13, 2006Date of Patent: August 18, 2009Assignee: Schaeffler KGInventors: Thomas Dittenhöfer, Stephan Popp, Günter Schmid, Detlef Rode, Jürgen Weyh, Karl Schāfer

Patent number: 6706205Abstract: A semiconductor processing article is characterized by extended useful life. The article is used in a semiconductor furnace system, particularly in a low pressure chemical vapor deposition furnace for prolonged periods without requiring cleaning to remove build-up film. The semiconductor processing article is a quartz body characterized by a surface roughness having a first component with an average deviation from a first mean surface of about 2.5 to 50 microns, and a second component with an average deviation from a second mean surface of about 0.25 to 5 microns.Type: GrantFiled: February 7, 2002Date of Patent: March 16, 2004Assignee: General Electric CompanyInventors: Thomas Bert Gorczyca, Udo Heinz Retzlaff, Stephan Popp
