Patent number: 10244682Abstract: A conveyor belt has one or more conveyor belt segments made of an elastomeric material layer and a reinforcement layer of steel ropes disposed in the elastomeric material layer and oriented in a longitudinal direction of the conveyor belt segment. The conveyor belt segments each have a first segment end provided with a first transverse lock bar and a second segment end provided with a second transverse lock bar, wherein ends of the steel ropes are locked frictionally or with form fit in the first and second transverse lock bars, respectively. One or more detachable closure members couple the first and second transverse lock bars of a single one or of adjacently positioned ones of the conveyor belt segments to each other in a rigid correlation relative to each other.Type: GrantFiled: February 22, 2017Date of Patent: April 2, 2019Assignee: Maschinenfabrik Krone Beteiligungs-GmbHInventors: Simon Hülsmann, Marco Lehmann, Klaus Martensen, Henrik Wermes

Patent number: 9394971Abstract: A planet web for connecting two planet web cheeks to form a planet wheel space of a planet carrier of a planet gear has, in the axial direction of the planet carrier, a cavity delimited by peripheral walls. A planet carrier includes the planet web and is improved in relation to the prior art, in particular from a production engineering aspect. This improvement is achieved by the planet web having at least one breach arranged in a peripheral wall of the planet web, which connects the cavity to the planet wheel space. A corresponding planet carrier, a casting core, and a method for manufacturing a planet carrier includes the planet web having the at least one breach.Type: GrantFiled: June 18, 2013Date of Patent: July 19, 2016Assignee: ZF FRIEDRICHSHAFEN AGInventors: Ralf Kleine-Brockhoff, Dominikus Daners, Marco Lehmann, Claudia Schweihoff

Patent number: 8814747Abstract: A planetary carrier of a planetary gearing includes two planet web cheeks interconnected by planet webs. The sides of the planet web cheeks are mutually opposed in the circumferential direction and, together with outer lateral surfaces of the planetary webs, define lateral surface openings. At least one planet pin opening for receiving a pin for mounting a planet gear is provided in at least one planet web cheek. At least one planet web cheek, in the region of the attachment of a planet web, has a transition reducing the axial length of the planet web. The planetary carrier is optimized in terms of weight and strength by way of the transition having a rounded contour in the form of a spherical recess.Type: GrantFiled: June 17, 2013Date of Patent: August 26, 2014Assignee: Robert Bosch GmbHInventors: Ralf Kleine-Brockhoff, Dominikus Daners, Miroslaw Roszkowski, Marco Lehmann, Claudia Schweihoff

Publication number: 20130340566Abstract: A housing for a gear mechanism, in particular a planetary gear mechanism, includes at least one gear-mechanism housing part that has at least one structure configured to reinforce the housing. The housing further includes at least one shaft mounted in the housing and gear-mechanism gearwheels. The housing is optimized with regard to its weight and its strength by virtue of the structure configured to reinforce the housing. The structure is configured as one or more of an undulating structure oriented in the circumferential direction of the gear-mechanism housing part and a bead structure oriented in the radial direction of the gear-mechanism housing part.Type: ApplicationFiled: June 19, 2013Publication date: December 26, 2013Inventors: Ralf Kleine-Brockhoff, Dominikus Daners, Marco Lehmann, Claudia Schweihoff

Patent number: 8597155Abstract: Planetary gearing, in particular multistage planetary gearing, is disclosed. The planetary gearing includes at least one drive shaft, an output shaft, a sun wheel, a ring gear, planet wheels assigned to the planetary gear train, a gear casing, in particular a multipart gear casing, a planetary gear train, in particular the second planetary gear train, comprising a planet wheel arm immovably arranged in a casing. The construction of such a planetary gearing is simplified compared to the prior art, thereby saving costs. This is achieved in that the planet wheel arm is integrally formed with a casing.Type: GrantFiled: June 13, 2012Date of Patent: December 3, 2013Assignee: Robert Bosch GmbHInventors: Klaus Noller, Gerhard Bauer, Thomas Matern, Wilfried Michel, Marco Lehmann

Publication number: 20070228224Abstract: A universally adjustable joint mechanism for supporting a linearly displaceable and braided wire cable including a first fixed component having a three-dimensional shape and size and exhibiting an interior extending passageway. A second component has a further three-dimensional shape and size and defines a communicating a second interior extending passageway. The second component is pivotally secured to the first component about a first axis defined by respective pairs of linearly extending and overlapping edges, and such that the braided wire cable extends successively through the end-to-end communicating and interior extending passageways associated with the pivotally secured components, and in a substantially non-linear extending fashion.Type: ApplicationFiled: March 31, 2006Publication date: October 4, 2007Inventor: Marco Lehmann
