摘要： The invention relates to an apparatus for the milling cutting and/or drilling of materials, in particular for removing rock, minerals or coal, comprising a tool drum (104) which is mounted on a drum carrier (101) such that it can rotate about a drum axis H, in which tool drum a plurality of tool shafts (105) which carry milling cutting/drilling tools (116) at their ends are mounted such that they can be driven to rotate, wherein at least two of the tool shafts (105) can be driven by a common gear drive which comprises output gearwheels (107) which are arranged in a rotationally fixed manner on the tool shafts (105), and a common drive element (108) which interacts with the output gearwheels (107), wherein the drive element (108) and the tool drum (104) can be rotated relative to one another. Provision is made according to the invention for the axes W of the tool shafts (105) to lie transversely with respect to the drum axis H. In the apparatus (110) according to the invention, a very short, compact, pulse-like engagement of the individual milling cutting/drilling tools (116) in the rock to be extracted can be achieved.

摘要： 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 (10) for coupling an engine to a gearbox of a machine is suggested, which comprises a housing (12) having an inner cavity (14) that extends from a first open end (16) of the housing (12) to a second open end (18) of the housing (12) and which is configured for accommodating and enclosing a clutch. The housing (12) defines a first coupling interface (20) at the first open end (16) for coupling the drive connection (10) to an engine and a second coupling interface (22) at the second open end (18) for coupling the drive connection (10) to a gearbox, Furthermore, each coupling interface (20, 22) comprises a sealing member (24), wherein the housing (12) and sealing members (24) are configured to fluidically seal the inner cavity (14), when the drive connection (10) is in a coupled state.

摘要： A mining machine includes a frame, a boom supported for pivoting movement relative to the frame, and a cutter head pivotably coupled to the boom. The cutter head includes a housing, a cutter shaft coupled to the housing, a cutting disc, and an excitation mechanism. A second portion of the cutter shaft extends parallel to a cutter axis. The cutting disc is coupled to the second portion of the cutter shaft and is supported for free rotation relative to the cutter shaft about the cutter axis. The cutting disc includes a plurality of cutting bits defining a cutting edge. The excitation mechanism includes an exciter shaft and a mass eccentrically coupled to the cutter shaft. The excitation mechanism is coupled to the first portion of the cutter shaft. Rotation of the exciter shaft induces oscillating movement of the second portion of the cutter shaft and the cutting disc.
