Publication number: 20220364638Abstract: The present invention pertains to a drive connection for coupling an engine to a gearbox of a machine and which provides a fluid-tight sealing. Accordingly, a drive connection for coupling an engine to a gearbox of a machine is suggested, which comprises a housing having an inner cavity that extends from a first open end of the housing to a second open end of the housing and which is configured for accommodating and enclosing a clutch. The housing defines a first coupling interface at the first open end for coupling the drive connection to an engine and a second coupling interface at the second open end for coupling the drive connection to a gearbox, Furthermore, each coupling interface comprises a sealing member, wherein the housing and sealing members are configured to fluidically seal the inner cavity, when the drive connection is in a coupled state.Type: ApplicationFiled: September 21, 2020Publication date: November 17, 2022Applicant: Caterpillar Global Mining Europe GmbHInventors: Michael NAFE, Dennis GRIMM, Thomas HOELKEN

Patent number: 9541187Abstract: The present disclosure generally refers to a transmission comprising a transmission housing and at least one transmission stage arranged in the transmission housing. The transmission stage may include, coaxially with respect to an axis, a sun gear, a planet carrier with at least two planet gears rotatably mounted on the planet carrier; and an internal gear as transmission parts. At least one stop means may be provided for limiting the axial movement of two transmission parts which are movable relative to one another. The stop means may comprise a ball pair with a first ball assigned to a first transmission part and a second ball assigned to a second transmission part. The two balls may be arranged so as to be rotatable about their ball center on the axis.Type: GrantFiled: April 23, 2013Date of Patent: January 10, 2017Assignee: Caterpillar Global Mining Europe GmbHInventors: Tobias Kleinbongartz, Adam Gacka, Alexander Jänsch, Andreas Scheer, Dennis Grimm, Jessica Johnson, Michael Nafe, Peter Pientka, Thomas Hoelken

Patent number: 9499347Abstract: A drive connection is disclosed. The drive connection may be configured to be interconnected between a main driving unit and a main gear unit of a driving device configured to drive a chain of a conveyor of a longwall device. The drive connection may have a housing configured to be connected to the main driving unit and to the main gear unit. The drive connection may also have a drive shaft disposed within the housing and configured to transmit torque from the main driving unit to the main gear unit. In addition, the drive connection may have a chain tensioning apparatus disposed within the housing. The chain tensioning apparatus may have a worm drive interacting with the drive shaft. The chain tensioning apparatus may be configured to drive the drive shaft for tensioning the chain of the conveyor when the main driving unit is in a non-operative state.Type: GrantFiled: April 24, 2014Date of Patent: November 22, 2016Assignee: Caterpillar Global Mining Europe GmbHInventors: Adam Gacka, Andreas Scheer, Dennis Grimm, Tobias Kleinbongartz, Thomas Hoelken, Michael Nafe, Peter Pientka, Svenja Bauhaus, Alexander Jänsch, Jessica Johnson
