摘要:
Die Erfindung geht aus von einer Getriebevorrichtung (10) zu einer Erzeugung einer Hub- und/oder Pendelbewegung eines Einsatzwerkzeugs (12) einer Handwerkzeugmaschine (14), mit zumindest einer Kulisseneinheit (16) zu einer Erzeugung der Hubbewegung, die zumindest ein Abtriebselement (18) mit zumindest einer Kontaktfläche (20), die zumindest teilweise an dem zumindest einen Abtriebselement (18) angeordnet ist, und zumindest ein Kulissenelement (22), das über die zumindest eine Kontaktfläche (20) mit dem zumindest einen Abtriebselement (18) zusammenwirkt, umfasst. Es wird vorgeschlagen, dass die zumindest eine Kulisseneinheit (16) zumindest eine weitere Kontaktfläche (24) zu einer Erzeugung einer Kraftkomponente zu einer Einleitung der Pendelbewegung umfasst, die zumindest teilweise an dem zumindest einen Abtriebselement (18) angeordnet ist.
摘要:
A saber saw including: a motor; a housing accommodating the motor; a plunger held to be reciprocatable in the housing and to which a blade is mounted at a leading end thereof, and a movement converting part provided between the motor and the plunger and is configured to convert rotation movement of the motor into reciprocating movement of the plunger, characterized in that: a bearing metal is fixed to an outer peripheral surface of the plunger.

A jigsaw (10) generally includes a housing (12) that contains a motor (18) activated by a trigger assembly (20). A reciprocating shaft (24) is connected to the motor (18) that extends from the housing (12) toward a cutting area. A laser module (100) is contained with a housing (120) operable to produce a laser light pattern forward of the cutting area. An upper connection portion (122) releaseably connects the housing (120) of the laser module (100) to the housing (12) of the jigsaw. A lower connection portion (124) pivotally couples the housing (120) of the laser module to the housing (12) of the jigsaw to permit the housing of the laser module to tilt away from the housing of the jigsaw to provide access to a rear area of the laser module.

Es wird eine Handwerkzeugmaschine, insbesondere Handsäge, angegeben, die innerhalb eines Gehäuses (11) einen elektrischen Antriebsmotor (12), ein diesem nachgeschaltetes Getriebe (13) und einen die Abtriebsdrehbewegung des Getriebes (13) in eine axial hin- und hergehende Arbeitsbewegung eines Hubelements (15) für den Antrieb eines Werkzeugs (16), insbesondere eines Sägeblattes, wandelnden Bewegungswandler (14) aufweist. Das Getriebe (13) und der Bewegungswandler (14) sind zu einer Getriebeeinheit (17) zusammengefasst. Die Getriebeeinheit (17) ist innerhalb eines robusten, biege- und verwindungssteifen Getriebegehäuses (40) angeordnet, das seinerseits in dem Gehäuse (11) aufgenommen ist. Das Gehäuse (11) ist aus flexiblem Kunststoff gebildet ( Fig. 1 ).

A machine (10,110,210,310,410) according to the present teachings includes a machine housing (12,112,312,412) and a drive mechanism (14,314,414) disposed in the machine housing and driving an output member (40,340,440). An input member (32,332,432) is associated with the machine housing for activating the drive mechanism. A working member (42,342,442) is driven by the output member. A light source is coupled to the machine housing that projects UV light onto an area proximate to the working member. According to additional features, the light source can comprise a UV light source. According to other features, the light source can collectively define a light emitting device and a filter. The filter can allow black light to pass therethrough. The light emitting device can comprise an incandescent bulb, a light emitting diode, or a fluorescent bulb according to various examples.

摘要:
A power tool comprising a reciprocating cuffing blade is disclosed with a dust or debris extraction arrangement and method. A motor fan is arranged to blow air into a conduit (40) which has an outlet (44) on one side of the power tool. The resulting air stream from the outlet (44) is directed towards the area of a work-piece (WP) where the blade (28) interacts with the work-piece (WP). The air stream is off-axis with respect to the intended line of cut (42) of the power tool. As a result, debris ejected on the work-piece (WP) is blown by the air stream away from the cut line (42) to leave the cut line (42) visible to the saw's operator during use.
摘要:
It is an object of the invention to provide a useful technique for reducing vibration of a handgrip and improving the cutting efficiency while achieving weight reduction of a reciprocating power tool. According to the invention, a representative reciprocating power tool is provided to comprise a body (103), a tool bit, an actuating mechanism, a handgrip (105). The handgrip and the body can rotate with respect to each other via a pivot (147) in a direction crossing the direction of reciprocating linear motion of the tool bit. An elastic element (149) is disposed between the handgrip and the body and serves to absorb vibration transmitted from the body to the handgrip by elastically receiving the relative rotation of the handgrip and the body. According to the invention, vibration in the handgrip can be reduced and the cutting efficiency can be improved without complicating the construction.
