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.
摘要翻译：采矿机械包括框架，被支撑用于相对于框架枢转运动的吊杆以及可枢转地联接到吊杆的刀头。刀头包括壳体，连接到壳体的切割器轴，切割盘和激励机构。切割器轴的第二部分平行于切割器轴线延伸。切割盘联接到切割器轴的第二部分并且被支撑以相对于切割器轴围绕切割器轴自由旋转。切割盘包括限定切割边缘的多个切割钻头。激励机构包括激励器轴和与切割器轴偏心耦合的质量。激励机构联接到切割器轴的第一部分。激励器轴的旋转引起切割器轴的第二部分和切割盘的摆动运动。

摘要： A cutter head includes a first member, a cutting bit, and a second member. The first member includes a first end and a second end and includes a first mass. The cutting bit is coupled to the first member proximate the second end. The cutting bit includes a cutting edge rotatable about the axis. The second member is rotatable about the axis and includes a second mass eccentrically positioned with respect to the axis. Rotation of the second mass causes the first member and the cutting bit to oscillate.
摘要翻译：切割头包括第一构件，切割钻头和第二构件。第一构件包括第一端和第二端并且包括第一质量。切削头在第二端附近与第一部件连接。切削刀头包括围绕轴线可旋转的切削刃。第二构件可围绕轴线旋转并且包括相对于轴线偏心定位的第二质量。第二个质量的旋转导致第一个构件和切割钻头振动。
