    • A portable, cordless, electrically energized grass trimming device is disclosed having a rotary cutter blade which is formed of a flexible strip of material and which is mounted for rotation over a predetermined course. A blade stabilizing means is provided for restraining the blade along a segment of its length for maintaining rotary motion of the blade in the predetermined course upon impact with other objects. The flexibility of the blade is enhanced by mounting the blade for rotation over a course described by a curved surface of revolution and blade durability is improved by providing a means for absorbing impact shock when the blade strikes an object. An improved blade is described having integrally formed resilient means for absorbing the shock of impact.
    • 公开了一种便携式,无绳电动通电的草地修剪装置,其具有旋转切割刀片,旋转切割刀片由柔性条带形成,并且安装成在预定的路线上旋转。 提供了一种叶片稳定装置,用于沿其长度的段限制叶片,以在与其它物体碰撞时保持叶片在预定过程中的旋转运动。 通过将旋转刀片安装在旋转弯曲表面所描述的路线上来提高刀片的灵活性,通过提供一种用于当刀片撞击物体时吸收冲击冲击的装置来改善刀片耐久性。 描述了一种改进的叶片,其具有用于吸收冲击冲击的整体形成的弹性装置。

    • A mower unit having a bevel gear mechanism includes an input shaft extending substantially horizontally; a first bevel gear mounted on the input shaft; an output shaft extending substantially vertically; a second bevel gear meshed with the first bevel gear and mounted on one end of the output shaft; a blade mounted on the other end of the output shaft; a blade housing coveting the blade and defining an opening for receiving the output shaft; a beating holder rotatably supporting the output shaft; a bevel gear case containing the first and second bevel gears; and a pair of fight and left support stays connected to the bevel gear case for mounting the bevel gear case to the blade housing. The bearing holder and support stays are interconnected by reamer bolts, with the blade housing interposed between flange surfaces formed on the beating holder and flange surfaces formed on the support stays. Soft metal packings are interposed between the flange surfaces of the support stays and upper surfaces of the blade housing.
    • 具有锥齿轮机构的割草机单元包括基本上水平地延伸的输入轴; 安装在输入轴上的第一锥齿轮; 输出轴基本垂直延伸; 与所述第一伞齿轮啮合并安装在所述输出轴的一端上的第二伞齿轮; 安装在输出轴的另一端的叶片; 刀片壳体包围刀片并限定用于接收输出轴的开口; 可旋转地支撑输出轴的跳动支架; 包含第一和第二锥齿轮的锥齿轮箱; 以及一对与伞形齿轮箱连接的战斗和左支撑支撑,用于将伞齿轮箱安装到叶片壳体。 轴承座和支撑撑杆通过铰刀螺栓相互连接,其中刀片壳体设置在形成在打浆保持器上的凸缘表面和形成在支撑架上的凸缘表面之间。 软金属填料插入在支撑撑条的凸缘表面和刀片壳体的上表面之间。

    • In a mowing machine having an engine for driving a rotary blade via a centrifugal clutch, a shaft and a reduction gear assembly, the outer diameter of the shaft is selected such that the torsional natural vibration frequency of the rotational system extending from the engine to the rotary blade is less than one third of a rotational frequency above which the centrifugal clutch starts transmitting the engine output torque to the shaft. As a result, the torsional natural vibration frequency of the rotational system does not equal the rotational frequency or the half or one third of the rotational frequency of the engine so that undesirable resonance phenomenon will not occur.
    • 在具有用于通过离心式离合器,轴和减速齿轮组件驱动旋转叶片的发动机的割草机中,选择轴的外径,使得从发动机延伸到旋转系统的旋转系统的扭转固有振动频率 旋转叶片小于旋转频率的三分之一,离心离合器开始将发动机输出扭矩传递到轴上方。 结果,旋转系统的扭转固有振动频率不等于发动机的转速或旋转频率的一半或三分之一,从而不会发生不期望的共振现象。
