Patent number: 8469600Abstract: A roller bearing cage for guiding rolling bodies in a rolling body bearing, which has multiple rolling bodies, two cage side elements, between which the rolling bodies are arranged, and which have multiple web appendages to guide the rolling bodies, and multiple connection elements that connect the two cage side elements. The azimuthal position of the connection elements defines a connection area. Exactly one connection element and at least one web appendage are arranged in a connection. The connection element and web appendage are arranged in sections inside a radial interior of the respective cage side elements, the border of which is defined by the positions of the rotation axes of the rolling bodies.Type: GrantFiled: December 19, 2007Date of Patent: June 25, 2013Assignee: Schaeffler Technologies AG & Co.

Patent number: 8277127Abstract: A bearing cage for large radial or axial roller bearings, which has two axially opposed, circular ring-shaped side washers held at a distance to each other by connecting elements, and roll-shaped rolling elements disposed between the side washers which have bolt-like elements on the faces thereof. A side washer on at least one side of the rolling element has radial recesses into which the bolt-like elements protrude. At least one securing element suitable for holding the bolt-like elements in the area of the radial recesses in the assembled state is provided. Shaped elements that can each be introduced at least partially into the radial recesses of the side washer are provided as the securing element. This construction achieves easy assembly and disassembly of the housing, allowing high flexibility in repairing a roller bearing so equipped.Type: GrantFiled: January 17, 2009Date of Patent: October 2, 2012Assignee: Schaeffler Technologies AG & Co.

Patent number: 7316168Abstract: The invention relates to a roller bearing comprising curved running paths, in addition to roller bodies and strain gauge sensors which are arranged between said running paths, said sensors being located in a groove on the outer diameter of the outer ring and/or on the inner diameter of the inner ring. The length of two adjacent strip conductor sections of the strain gauge sensor varies in such a way as to measure the angular position of the roller bodies between the strip conductors.Type: GrantFiled: November 19, 2003Date of Patent: January 8, 2008Assignee: FAG Kugelfischer AGInventors: Henri van der Knokke, Rainer Wunderlich, Karin Hauser, Roman Hollweck

Publication number: 20050062364Abstract: A surface acoustic wave sensor is applied to an object by an adhesive. There are reflectors on the sensor body used to determine expansion and contraction. Additional reflectors on a smoothed edge zone of the body remain at the same distance apart and the sensor temperature is determined from the difference signal between these reflectors. The edge zone is without the adhesive.Type: ApplicationFiled: March 12, 2003Publication date: March 24, 2005Inventor: Henri Van Der Knokke

Patent number: 6484582Abstract: A rolling bearing which has as rolling bearing components one bearing race with a first running surface, a second bearing race with a second running surface opposed to the first surface, and rolling elements arranged between the running surfaces. At least one sensing unit is integrated into the rolling bearing components. The sensing unit can be interrogated by radio via antennas or can be connected to an interrogator by a cable. The sensing unit uses at least one component operating on the SAW or BAW principle to sense changes in length and/or changes in temperature in the material of the rolling bearing component and sends the result of the measurement after the arrival of a radio signal via the antenna or via a cable.Type: GrantFiled: April 10, 2001Date of Patent: November 26, 2002Assignees: FAG OEM und Handel AG, Institut fur Mikrotechnik Mainz GmbHInventors: Wolfgang Ehrfeld, Volker Graeff, Frank Michel, Sven Gempper, Jens Heim, Joachim Hering, Horst Masuch, Edgar Streit, Vasilis Hassiotis, Henri Van Der Knokke

Patent number: 6364533Abstract: A metal window cage for a rolling bearing and supporting cylinder rollers. The cage having at least one ladder-shaped bent segment which is bent around to define the window cage. A joint is formed at adjacent cage segment ends which are interlocked in a dovetail shape lock at the segment ends. A connecting element connects the segment ends. The crosspieces at intervals along the cage segment and the connecting element at the joint are encapsulated by being molded over. Cylinder roller retaining clips are provided at the connecting element at the segment ends at the joint and also at the crosspieces between neighboring windows for cylinder rollers. The clips project radially inwardly to prevent the rollers from leaving the cage prior to installation of the cage and rollers in a bearing. The crosspieces and clips there are also molded over to retain them at the cage.Type: GrantFiled: June 30, 2000Date of Patent: April 2, 2002Assignee: Fag Oem und Handel AGInventor: Henri van der Knokke
