Abstract
Die Erfindung geht von einem Elektromotor (10) mit einem Ankerpaket (12) aus, das fest auf einer Ankerwelle (14) sitzt, dessen eines Ende mittels eines Kugellagers (40) in einem Polgehäuse (22) und dessen anderes Ende mittels eines weiteren Kugellagers (24) in einem Getriebegehäuse (20) drehbar gelagert und an einem freien Ende mit einer Schnecke (16) fest verbunden ist, wobei innere Lagerringe (28, 44) auf der Ankerwelle (14) sitzen, während äußere Lagerringe (30, 46) der Kugellager (24, 40) mit jeweils einem Gleitsitz in die Gehäuse (20, 22) eingepasst sind und sich mindestens ein äußerer Lagerring (30, 46) über ein Federelement (36) axial an dem zugeordneten Gehäuse (20, 22) abstützt, wobei sich mindestens ein innerer Lagerring (28, 44) zum Ankerpaket (12) hin jeweils gegen eine Stütze (32, 48, 54, 56) der Ankerwelle (14) axial abstützt. Es wird vorgeschlagen, dass ein einziges Federelement (36) an dem getriebegehäuseseitigen Kugellager (24) vorgesehen ist, während sich der äußere Lagerring (46) des polgehäuseseitigen Kugellagers (40) unmittelbar an einer Schulter (52) des Polgehäuses (22) abstützt.The invention is based on an electric motor (10) with an armature packet (12) which sits firmly on an armature shaft (14), one end of which by means of a ball bearing (40) in a pole housing (22) and the other end by means of another ball bearing (24) is rotatably mounted in a gear housing (20) and fixedly connected at one free end to a worm (16), wherein inner bearing rings (28, 44) are seated on the armature shaft (14) while outer bearing rings (30, 46) the ball bearings (24, 40) are each fitted with a sliding fit into the housings (20, 22) and at least one outer bearing ring (30, 46) is axially supported on the associated housing (20, 22) via a spring element (36), wherein at least one inner bearing ring (28, 44) to the armature package (12) towards each axially against a support (32, 48, 54, 56) of the armature shaft (14). It is proposed that a single spring element (36) on the transmission housing side ball bearing (24) is provided, while the outer bearing ring (46) of the pole housing side ball bearing (40) directly on a shoulder (52) of the pole housing (22) is supported.

Offenbarung der ErfindungDisclosure of the invention
Nach der Erfindung ist ein einziges Federelement an dem getriebegehäuseseitigen Kugellager vorgesehen, während sich der äußere Lagerring des polgehäuseseitigen Kugellagers unmittelbar an einer Schulter des Polgehäuses abstützt. Durch die erfindungsgemäße Gestaltung ergibt sich mit einfachen Mitteln eine spielfreie und damit geräuscharme Lagerung der Ankerwel le mit einem guten Wirkungsgrad. Die Ankerwelle ist einfach herzustellen und zu montieren, gleichgültig, ob der innere Lagerring der Kugellager auf der Ankerwelle als separates Bauteil montiert oder integraler Bestandteil der Ankerwelle ist. Dabei können für die Presssitze der inneren Lagerringe enge Toleranzen der Ankerwelle genutzt werden, während die Gleitsitze an den äußeren Lagerringen grobere Toleranzen zulassen.To The invention is a single spring element on the transmission housing side Ball bearings provided while the outer Bearing ring of the pole housing side ball bearing directly supported on a shoulder of the pole housing. By the design of the invention results with simple means a backlash-free and therefore quiet Storage of Ankerwel le with a good efficiency. The armature shaft is easy to make and assemble, no matter whether the inner bearing ring of the ball bearings on the armature shaft as a separate Component mounted or integral part of the armature shaft is. It can for the press seats of the inner bearing rings tight tolerances of the armature shaft are used while the sliding seats on the outer bearing rings coarser Allow tolerances.
Zweckmäßigerweise werden die inneren Lagerringe auf die Ankerwelle gepresst. Sie können zusätzlich auf der Seite des Ankerpaketes durch eine Stütze axial gesichert werden. Gemäß einer Ausgestaltung der Erfindung kann die axiale Stütze durch einen in eine Nut eingelassenen Federring oder einen anrollierten Bund oder eine Hülse gebildet werden, die sich am Ankerpaket abstützt. Die so gestalteten axialen Stützen werden vorzugsweise an dem polgehäuseseitigen Kugellager angewendet, sie können aber auch optional bei dem getriebegehäuseseitigen Kugellager verwendet werden.Conveniently, The inner bearing rings are pressed onto the armature shaft. You can additionally on the side of the anchor package by a support secured axially. According to one embodiment the invention, the axial support by a in a Groove recessed spring ring or a rolled up collar or a Sleeve are formed, which is supported on the anchor package. The thus configured axial supports are preferably applied to the polgehäuseiteitigen ball bearing, they can but also optional with the gearbox-side ball bearing be used.
