摘要： An improved drum-cutter mining machine design which transmits force exerted upon a drive wheel during translation of the mining machine along a rack structure to the machine. A protective housing encloses gears and a drive wheel in a manner such that feed forces exerted upon a drive wheel are transmitted through the housing to the mining machine.

摘要： A hollow gearwheel has internal teeth that mesh directly or through an intermediate gear with the teeth of a drive gear of a machine drive on a drum cutter mining machine. External teeth on the hollow gearwheel mesh with the teeth of a rack extending over the distance traversed by the mining machine along the face of a longwall mine. A plate pivots about the rotational axis of the drive gear while the plate forms a closure to the side of the hollow gearwheel facing the mining machine. The plate carries a bearing support for the arbor shaft of the hollow gearwheel and forms a seal along the outer peripheral edge of the hollow gearwheel. A carrier includes a bearing to support the outer end of the arbor shaft. The carrier is moved along a recess in a housing for the hollow gearwheel to adjust, by pivotal positioning, the hollow gearwheel.
摘要翻译：中空齿轮具有内齿，其直接或通过中间齿轮啮合在滚筒切割机上的机器驱动器的驱动齿轮的齿。中空齿轮上的外齿与齿条的齿啮合，其延伸超过采矿机沿长壁矿井的表面穿过的距离。板在围绕驱动齿轮的旋转轴线枢转的同时，板形成与面向采矿机的中空齿轮侧的闭合。该板承载中空齿轮的心轴轴承，并沿中空齿轮的外周缘形成密封。载体包括用于支撑心轴的外端的轴承。托架沿着用于中空齿轮的壳体中的凹部移动，以通过枢转定位来调节中空齿轮。

摘要： Drive gears with unique teeth profiles drivingly couple the output shaft of a drive on a drum-cutter mining machine to a rack extending along the course of travel of the mining machine. A prime mover on the mining machine is coupled to a drive gearwheel having gear teeth with tooth flanks defined by segments of a hypocycloid. These gear teeth mesh with a rack drive gearwheel having gear teeth with tooth flanks defined by segments of an epicycloid. The gear teeth of the rack drive gearwheel have a slender profile to penetrate into the spaces between pins forming part of a guide rail rack.

摘要： A long wall mining machine includes a drum cutter-loader and face conveyor wherein the drum cutter-loader is overhung and is supported by a support arm adjacent to the mine face. Nozzles direct high pressure liquid jets against the forward edge of the support arm to cut away the mining face and permit the face side support arm to advance as the mining machine advances. In one embodiment the nozzles are provided along an inclined cutting edge at the forward end of the support arm. Such nozzles may be fixed or oscillating. In an alternative embodiment the nozzles are provided in the cylindrical edge zone of the shearer drum and direct the high pressure fluid jets against the cutter edge at the forward end of the support arm.
摘要翻译：一种长壁采矿机包括滚筒式装载机和面式输送机，其中滚筒式装载机是悬挂式的并且由靠近矿井的支撑臂支撑。喷嘴将高压液体射流引导到支撑臂的前边缘，以切割采矿面，并允许面侧支撑臂随着采矿机前进而前进。在一个实施例中，喷嘴沿着支撑臂的前端处的倾斜切割边缘设置。这样的喷嘴可以是固定的或摆动的。在替代实施例中，喷嘴设置在采煤机滚筒的圆柱形边缘区域中，并将高压流体射流引导到支撑臂前端处的切割刃。
