    摘要： The invention relates to a portable handheld work apparatus having an electric drive motor mounted in a housing. A switch unit switches a supply voltage onto the drive motor. The switch unit is actuated by a switching extension of a switching lever journalled in a handle of the work apparatus. The switching lever has an actuating portion which extends outwardly from the handle housing. An elastic resilient tongue is arranged on the switching lever in order to ensure a trouble-free opening of the electric contacts of the switch unit and to ensure that an adequate contact spacing in the at-rest position is maintained. The tongue lies against an abutment fixed in the housing and the switching lever is held under a spring force against an at-rest stop in the handle housing.

    摘要： A piston for a two-cycle engine having a piston head and a piston wall in which are disposed wrist pin eyes. At least one undercut is formed between the underside of the piston head and the wrist pin eyes at a distance from the piston head. The undercut extends from the interior of the piston toward the piston wall. A respective thickened portion is provided in at least one region of the piston that is rotationally shifted about the longitudinal axis of the piston by 90° relative to one of the wrist pin eyes. The thickened portion is disposed at a distance below the piston head and extends into the interior of the piston.

    摘要： A vegetation cutter apparatus having a drive motor which drives a cutterhead via a drive shaft journalled in a guide tube, The cutterhead is held in a sleeve bearing at the end section of the guide tube facing away from the drive motor, The cutterhead is held in a simple manner by an exchangeable sleeve bearing in the guide tube. This is achieved in that the bearing is axially held in the end section of the guide tube so as to be exchangeable and at least one stop holds the bearing against rotation and may cooperate to hold the bearing captive in the axial direction. The stop projects radially into the guide tube.

    摘要： The invention is directed to a portable handheld tool such as a brushcutter which includes a work tool assembly and a drive motor connected by a drive shaft. The drive shaft is surrounded by a protective tube and is centrally held therein by means of a bearing sleeve unit. The bearing sleeve unit braces itself against the inner peripheral wall surface of the protective tube via outwardly extending support ribs. The bearing sleeve unit defines a bearing bore for holding and guiding the drive shaft within the protective tube. The bearing bore and the drive shaft conjointly define an annular bearing play gap therebetween whereby frictional heat generated in the bearing sleeve unit is reduced while vibrations of the drive shaft are developed and imparted to the bearing sleeve unit. The support ribs are configured so as to be resilient in the radial direction to attenuate the vibrations imparted to the bearing sleeve unit. A plurality of impact ribs extends substantially radially from the outer surface of the center portion for impacting against the inner wall surface in response to the vibrations thereby limiting the amplitude thereof.

    摘要翻译： 本发明涉及一种便携式手持工具，例如刷子，其包括工作组件和通过驱动轴连接的驱动马达。 驱动轴由保护管包围，并通过轴承套单元中心地保持在其中。 轴承套筒单元通过向外延伸的支撑肋来抵抗保护管的内周壁表面。 轴承套单元限定用于保持和引导保护管内的驱动轴的轴承孔。 轴承孔和驱动轴联合地限定环形轴承间隙，由此在轴承套筒单元中产生的摩擦热减小，同时驱动轴的振动被显影并赋予轴承套筒单元。 支撑肋构造成在径向上具有弹性，以减弱施加到轴承套筒单元的振动。 多个冲击肋从中心部分的外表面基本上径向延伸，以响应于振动而撞击内壁表面，从而限制其振幅。

    摘要： An engine has a cylinder wherein a reciprocating piston is mounted. The piston drives, via a connecting rod (6), a crankshaft (7) pivotably mounted in a crankcase. The connecting rod is connected to the piston via a piston pin. An inlet window for combustion air is provided and controlled by the piston. The piston separates a combustion chamber from the crankcase interior space and has a piston base the underside of which is oriented toward the crankcase. To achieve good cooling of the piston and of the piston pin bearing, a first flow-guide element is provided within the crankcase interior space adjacent to the inlet window. The first flow-guide element redirects the combustion air flowing in through the inlet window in the direction of the underside of the piston base.

A centrifugal clutch is positioned in the clutch housing. A drive shaft with a first and a second end is provided. The centrifugal clutch detachably connects the output shaft to the first end of the drive shaft. The centrifugal clutch has fly weights connected to the output shaft and a clutch drum connected to the first end of the drive shaft. This clutch drum surrounds the output shaft and the fly weights. A cutting element is connected to the second end of the drive shaft. A protective tube having a proximal end connected to the clutch housing and a distal end connected to the cutting element is provided. The drive shaft is enclosed in the protective tube. A bearing element is positioned at the first end of the drive shaft. Radial play is provided between the bearing element and the first end of the drive shaft. This radial play is smaller than the distance between the fly weights and the clutch drum.
