摘要： A force-transmitting arrangement for use in hammer drills and the like includes an internal thread in a chuck of a power tool and an external thread on a portion of the tool element which is to be mounted in the chuck, both threads being of compatible, basically trapezoidal, configurations. The flat flanks of the trapezoidal internal and external threads are offset in the radially outward direction with respect to the mean effective thread diameter. The external thread is rounded at its root with a radius substantially corresponding to the thread height of the external thread, and the internal thread is similarly rounded at its crest with a radius substantially corresponding to the thread height of the external thread, and/or chamfered.

摘要： A torque-transmitting system, particularly a hammer drill, has a housing provided with a tool holder section, and a driven output shaft which is journalled in the housing and has a free end portion at the tool holder section. A tool has a shaft provided with an end portion of profiled cross-section, the profiling of the cross-section being inclined circumferentially of the end portion. A receiver for the end portion is formed in the tool holder and configurated for matingly receiving the profiled end portion, so that the tool is held in the tool holder section in motion-transmitting relationship with the free end portion of the shaft.

摘要： A vacuum sweeper, particularly for collecting borings, has an upright cylindrical receptacle with a tangential inlet for admission of an air stream which carries borings and/or other solids and an open top which is overlapped by a platelike air filter disposed below a cover which is separably connected with the receptacle and has downwardly extending projections to prevent upward flexing of the filter. A side channel vacuum pump is installed in the cover and has an inlet which draws air from the receptacle via filter and a passage of the cover, and an outlet which communicates with a sound deadening annular channel provided in the cover and concentrically surrounding the rotor of the pump. The open end of the channel extends upwardly and contains a spherical float which rises therein to a level indicating the rate of air flow from the channel. Certain surfaces bounding the channel in the cover are lined with layers of closed-pore deformable foamed synthetic plastic material which contributes to the soundproofing action. The rotor of the pump rotates about a vertical axis and is driven by an electric, hydraulic or pneumatic motor.

摘要： A portable torque and impulse transmitting machine comprises an elongated housing having a median plane of symmetry which extends in direction of the elongation of the housing, and a tool holder which is mounted on the housing for holding a material-penetrating tool. A drive motor is mounted in the housing and has a rotary output shaft which is mounted in the housing so as to lie in and substantially bisect the median plane. An impeller assembly is also mounted in the housing and includes an impeller mounted for reciprocting movement therein and operative for transmitting impulses to the tool. A first power train is mounted in the housing and arranged to effect reciprocatory movement of the impeller in response to rotation of the rotary shaft of the drive motor. The first power train comprises a crank gear having an axis of rotation which is substantially parallel to the rotary shaft and which is also offset from the median plane. A second power train is mounted in the housing and arranged to transmit torque to the tool in the holder. The second power train includes an intermediate gear laterally adjacent the crank gear and in motion-transmitting engagement therewith. A safety overload clutch is mounted in series between the rotary shaft of the motor and the tool and is operative to terminate the transmission of torque from the rotary shaft to the tool when the latter encounters a resistance to rotation which exceeds a predetermined value.

摘要： A self drilling anchoring dowel for drilling a hole into a hard support structure and anchoring in this hole to be available as a fixture by means of which an object may be attached to the support structure. The dowel is formed as an elongated dowel body having a front end and a rear end. At the front end, a drilling head is formed and, spacedly from the rear end, a circumferential weakened zone is provided in the wall of the dowel body in which zone the thickness of this wall is diminished. Thus, at the rear end of the dowel body, a rear terminal section is delimited which may be broken off therefrom after the dowel has been driven to a desired depth into the structure, so that a front end is provided on the dowel body which end is substantially flush with the structure surface. A longitudinal bore inside the dowel body extends therethrough and is available for removing from the drilled hole waste chips and dust produced by drilling. The bore is constricted in the region of the drilling head for preventing entrance into the bore of large chips of the severed material possibly jamming the bore.The dowel is devised to be used in connection with a hammer drill having exhausting means, so that the waste chips and drilling dust are evacuated and do not infest the surrounding atmosphere. The rear terminal section of the dowel body is configurated to be engageable by a dowel holder attached to the hammer drill.
摘要翻译：一种用于将钻孔钻入硬支撑结构中并锚固在该孔中的自钻锚定榫钉，可用作固定装置，通过该固定装置可将物体附接到支撑结构。销钉形成为具有前端和后端的细长定位销主体。在前端，形成钻头，并且与后端间隔开，在定位销主体的壁上设有周向的弱化区域，在该区域中，该壁的厚度减小。因此，在榫钉体的后端处，后端子部分被界定，在榫钉已经被驱动到期望的深度进入结构之后，该后端子部分可以从其中断开，使得前端设置在榫头本体上，该端部与结构表面基本齐平。榫钉体内部的纵向孔延伸穿过其中，并且可用于从钻孔中除去废屑和通过钻孔产生的粉尘。在钻头的区域中孔被收缩，以防止进入可能堵塞孔的切断材料的大芯片的孔中。
