Patent number: 11026300Abstract: A telescopic slide for a microwave oven has a first slide element and a second slide element each having two running surfaces with caged rolling bodies arranged on the running surfaces. The slide elements can be moved along against each other between a retracted position and an extended position. The slide elements each have at least one electrically conductive contact element arranged on the slide elements in such a way that in the retracted position either the contact elements are directly in engagement or that the contact element of the first slide element and the contact element of the second slide element are each in engagement with an electrically conducting conductive element that is moved concomitantly with the rolling-body cage. The result is that in the retracted position there is an electrically conducting connection between the first and the second slide elements, and in at least one position other than the retracted position the electrically conducting connection is broken.Type: GrantFiled: October 12, 2018Date of Patent: June 1, 2021Assignee: Accuride International GmbHInventors: Andreas Heffel, Philipp Krebs

Patent number: 10047793Abstract: A cage for a roller bearing is provided. The cage has a ring-shaped base body with a plurality of pockets for receiving rolling elements. The base body is formed by two side rings arranged in a defined axial distance and by a plurality of pocket elements, which are located between the side rings. Each pocket element has two face sides designed for contacting a rolling element. The connection between the pocket element and each of the side rings is established by at least one beam joined with one of the side rings and the pocket element. The beam is a positive substance joined with one of the side rings and the pocket element and has a ring-shaped or elliptical cross section in a section perpendicular to the longitudinal extension of the beam.Type: GrantFiled: June 29, 2015Date of Patent: August 14, 2018Assignee: AKTIEBOLAGET SKFInventors: Philipp Krebs, Gilbert Peters, Sebastian Ziegler, Gregory A Zimmerman

Patent number: 9695871Abstract: An assembly that includes a rotating shaft supported with respect to a stationary housing by at least one active magnetic bearing presenting a mean radial air gap and at least one auxiliary bearing having a bushing fixed to the housing and a sleeve fixed on the rotating shaft. The bushing and the sleeve have opposite surfaces that define a clearance (E2) which is less than the mean radial air gap (E1). The bushing and the sleeve each exhibit symmetry around a longitudinal axis of the shaft and have different profiles in a longitudinal cross-section including the longitudinal axis to optimize the contact pressure distribution when the rotating shaft lands on the auxiliary bearing.Type: GrantFiled: May 29, 2014Date of Patent: July 4, 2017Assignees: SKF MAGNETIC MECHATRONICS, AKTIEBOLAGET SKFInventors: Philipp Krebs, Jens Anders, Eddy Herisse, Frederic Ponson
