Patent number: 10962052Abstract: A guide rail, for use with a guide carriage having at least one row of rolling elements, extends along a longitudinal axis and has at least one running surface for the rolling elements, a separate heat sink, and a plurality of first through holes. The running surface is arranged parallel to the longitudinal axis. The heat sink extends along the longitudinal axis and lies against the guide rail. At least sections of the heat sink delimit a first and a second cooling channel that each extend along the longitudinal axis. The first through holes are distributed along the longitudinal axis and are configured to receive screw-bolts. The heat sink has a plurality of second through holes, each aligning with and continuing an associated first through hole. The first and second cooling channels are located on opposite sides of the plurality of second through holes.Type: GrantFiled: May 9, 2017Date of Patent: March 30, 2021Assignee: Robert Bosch GmbHInventors: Gerd Spatschek, Michael Korbacher, Carsten Pfeuffer, Roland Greubel, Marius Feuerbach

Patent number: 9488223Abstract: A guide carriage for an elongated guide rail includes a main body, an end cap, and at least one row of rolling bodies accommodated in a continuous bypass channel. The end cap bears indirectly against a longitudinal end face of the main body and has a fastening bore through which a fastening screw passes. The fastening screw is screwed into the main body. The continuous bypass channel has a supporting portion and a return channel that are connected via a curved bypass channel that is arranged in the end cap. A lubricant flow path is arranged in the end cap and extends from a lubrication port to the row of rolling bodies. A first cavity is arranged between the fastening bore and the fastening screw. The first cavity forms a component of the lubricant flow path.Type: GrantFiled: May 27, 2015Date of Patent: November 8, 2016Assignee: Robert Bosch GmbHInventors: Gerhard Roesch, Stefan Dorn, Martina Elting, Matthias Zeier, Juergen Schenk, Sebastian Schierling, Michael Korbacher, Gerd Spatschek, Wolfgang Kuellstaedt, Richard Kuehnlein

Patent number: 9476451Abstract: A guide carriage is configured for use with an elongate guide rail. The guide carriage has at least one row of spherical rolling bodies which are received in an associated endless circulatory channel. The circulatory channel has a load-bearing section and a return channel which are connected to one another at their ends which lie opposite one another via in each case one curved deflection channel. The load-bearing section is delimited by a carriage raceway extending in a longitudinal direction on the guide carriage and a rail raceway on the guide rail. A separate main body of metal is also provided. The carriage raceway is arranged on a separate raceway insert which bears against the main body. A separate rolling-body guide part is also provided which has a guide section extending in the longitudinal direction. The guide section engages behind the raceway insert.Type: GrantFiled: May 28, 2015Date of Patent: October 25, 2016Assignee: Robert Bosch GmbHInventors: Martina Elting, Juergen Schenk, Michael Korbacher, Stefan Dorn, Marco Stock, Mario Ziegler, Gerd Spatschek, Peter Schlegel

Patent number: 9404539Abstract: A guide carriage is configured for use with an guide rail. The guide carriage has at least one row of rolling bodies received in a circulatory channel. The circulatory channel has a load-bearing section and a return channel connected together at their ends by a deflection channel. The load-bearing section is delimited by a carriage raceway on the guide carriage and a rail raceway on the guide rail. At least one sealing lip is arranged in sealing engagement with the guide rail when the guide carriage is mounted on the guide rail. At least one separate rolling-body guide part, composed in one piece of an elastomer, has two deflection sections, between which at least one guide section, extending longitudinally, is arranged. An associated sealing lip is arranged on the guide section. At least one radially inner deflection surface of a deflection channel is arranged on each deflection section.Type: GrantFiled: May 28, 2015Date of Patent: August 2, 2016Assignee: Robert Bosch GmbHInventors: Martina Elting, Matthias Zeier, Gerhard Roesch, Stefan Dorn, Juergen Schenk, Sebastian Schierling, Michael Korbacher, Gerd Spatschek, Wolfgang Kuellstaedt, Richard Kuehnlein
