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。
