Abstract
Description
Das technische Gebiet zu dem die Erfindung gehört, umfaßt alle handbetriebenen Arbeitsgeräte mit einem Motor als Antrieb und die es bis jetzt nur mit einem Netz-gespeisten Elektromotor oder mit einem Akku-gespeisten Gleichstrommotor gibt.The technical field to which the invention belongs includes all hand-operated tools with a motor as drive and which until now was only with a mains-powered electric motor or with a battery-powered DC motor.
Der Nachteil bei diesen Geräten ist, daß der Anwender sich ent weder für eine leistungsstarke Netzmaschine, oder für eine weniger leistungsstarke aber flexible Akkumaschine entscheiden muß.The disadvantage of these devices is that the user ent neither for a powerful network machine, nor for one decide less powerful but flexible battery machine got to.
Die entscheidende Neuerung bei der Maschine ist, daß sie wahl weise im Netzbetrieb oder im Akkubetrieb benutzt werden kann.The key innovation in the machine is that you choose can be used in AC or battery mode.
Der Akku-gespeiste Gleichstrommotor (1) und der Netz-gespeiste Elektromotor (2) der Maschine sind im Gehäuse (3) nebeneinander angebracht. Die beiden Motoren sind jeweils über einen Hülsen freilauf (12) der auf der Motorwelle angebracht ist, mit dem Ge triebe verbunden. Mit der Getriebeankoppelung durch die Hülsen freiläufe wird gewährleistet, daß der sich jeweils nicht im Be trieb befindliche Motor nicht unnötig mitgedreht wird.The battery-powered DC motor ( 1 ) and the mains-powered electric motor ( 2 ) of the machine are installed side by side in the housing ( 3 ). The two motors are each connected via a sleeve freewheel ( 12 ) which is attached to the motor shaft with the gearboxes. With the gear coupling through the sleeves freewheels ensures that the motor that is not in operation is not rotated unnecessarily.
Außer den beiden Motoren ist noch das Bohrfutter (3) mit dem Ge triebe (11) verbunden.In addition to the two motors, the drill chuck ( 3 ) is connected to the gear ( 11 ).
Im Griff (7) der Maschine befindet sich der Akku (6) für den Gleichstrombetrieb.The battery ( 6 ) for DC operation is located in the handle ( 7 ) of the machine.
Am unteren Griffende ist die Anschlußbuchse (8) für das Netzkabel. An der Anschlußbuchse ist ein Unterbrecherkontakt (10) angebracht, der bei Anschluß des Netzkabels den Gleichstromkreislauf unter bricht. Hiermit wird gewährleistet das bei Betätigung des Be triebsschalters nur ein Motor gestartet wird.At the lower end of the handle is the connection socket ( 8 ) for the mains cable. At the connection socket an interrupter contact ( 10 ) is attached, which breaks the DC circuit when the power cord is connected. This ensures that only one motor is started when the operating switch is actuated.
Der Betriebsschalter (5) der Maschine, der am oberen Griffende angebracht ist hat 2 Schließer jeweils einen für den Akku- und den Netzbetrieb.The operating switch ( 5 ) of the machine, which is attached to the upper end of the handle, has two NO contacts, one each for battery and mains operation.
Die Entstörung des Netzmotors erfolgt über eine elektrische Be schaltung (13) die neben dem Schalter im Griff untergebracht ist.The mains motor is suppressed by an electrical circuit ( 13 ) which is located next to the switch in the handle.
Vorteile der Netz-Akkuhandbohrmaschine:Advantages of the cordless cordless hand drill:
- - Die Maschine kombiniert bei einer kompakten Bauweise das starke Drehmoment und die hohe Drehzahl einer Netzmaschine, mit der Flexibilität einer Akkumaschine.- The machine combines the strong with a compact design Torque and the high speed of a network machine with which Flexibility of a battery machine.
- - Auch bei einem alten bzw. defekten Akku hat man im Netzbetrieb die volle Gerätefunktion.- Even with an old or defective battery, you have mains operation the full device function.
- - Die Maschine ist kaum größer und schwerer als eine herkömmliche Akkumaschine.- The machine is hardly bigger and heavier than a conventional one Battery machine.
- - Bei nicht ausreichender Leistung im Akkubetrieb kann im Netz betrieb weiter gearbeitet werden ohne das eine andere Maschine geholt werden muß.- If the battery power is not sufficient, the power supply can operation can continue without another machine must be fetched.
Claims (13)
- - Die beiden Antriebseinheiten für den Netz- und den Akkubetrieb können aber auch hintereinander auf einer Welle angebracht sein. Die Entstörung des Netzmotors ist über eine elektrische Beschal tung (13) vorgesehen.
- - The two drive units for mains and battery operation can also be attached in series on a shaft. The interference suppression of the mains motor is provided via an electrical circuit ( 13 ).
- - Die Aufladung des Akkus kann auch durch ein in der Maschine eingebautes Netzteil erfolgen, welches bei Anschluß des Netz kabels aktiviert wird.
- - The battery can also be charged by a built-in power pack, which is activated when the power cord is connected.
- - Diese Abkoppelung der jeweils nicht benutzten Antriebsanheit kann auch durch eine mechanische Versetzung im Getriebe erfolgen.
- - This uncoupling of the drive unit that is not being used can also be achieved by mechanical displacement in the gearbox.
