Description

Die Erfindung bezieht sich auf ein Verfahren zur Einstellung des Axialspiels gemäß Oberbegriff des Anspruchs 1 bzw. des Anspruchs 2; ein Verfahren gemäß Oberbegriff des Anspruchs 1 ist aus der EP-B1 01 75 798 und ein Verfahren gemäß Oberbegriff des Anspruchs 2 durch die DE-AS 11 78 934 bzw. das DE-GM 19 96 096 bekannt.The invention relates to a method for adjusting the axial play according to the preamble of claim 1 and claim 2; a method according to the preamble of claim 1 is known from EP-B1 01 75 798 and a method according to the preamble of claim 2 by DE-AS 11 78 934 and DE-GM 19 96 096.

Im bekannten Fall der vorgenannten EP-B1 01 75 798 ist die zusammen mit einer betriebsmäßig vor einer Stirnseite des Rotorblechpakets angeordneten Isolierendscheibe als ein­ stückiges Spritzgußteil hergestellte Abstandshülse vor ihrem Aufstecken bzw. Aufdrücken auf die Rotorwelle mit einer zwi­ schenliegenden Soll-Schwachstelle in Form von über den Umfang verteilten ausreißbaren bzw. ausbrechbaren Zwischenstegen oder mit in Form über den Umfang im gegenseitigen radialen Abstand unter Freilassung von Lücken scharnierartig angeordneten, ela­ stisch nachgebenden Zwischenstegen versehen, wobei zum Ein­ stellen des Axialspiels entweder unter Ausreißen bzw. unter elastischem Verbiegen der Zwischenstege das lagerseitige Ende der Abstandshülse auf das isolierscheibenseitige Ende der Ab­ standshülse hin axial verschoben wird.In the known case of the aforementioned EP-B1 01 75 798, the spacer sleeve, which is arranged together with an insulating disk which is operationally arranged in front of an end face of the rotor laminated core, is a one-piece injection molded part before it is plugged or pressed onto the rotor shaft with an intermediate weak point in the form of over the circumferential spreadable or breakable intermediate webs or with hinge-like arranged over the circumference at the mutual radial distance with the release of gaps, ela-elastic yielding intermediate webs, to set the axial play either with tearing or with elastic bending of the intermediate webs the bearing side End of the spacer sleeve is axially displaced toward the insulating-disk-side end of the stand-off sleeve.

Im Fall der vorgenannten DE-AS 11 78 934 wird eine Abstands­ hülse in Tonnenform zur Einstellung des Axialspiels etwas zusammengedrückt und dadurch axial verkürzt; im Fall des vor­ genannten DE-GM 19 96 096 sind jeweils eine Anlaufscheibe und eine Zahnscheibe vorgesehen, deren gegen die Anlaufscheibe an­ liegenden Zähne unter Anwendung von hohem Druck verformt werden. In the case of the aforementioned DE-AS 11 78 934 there is a distance sleeve in barrel shape to adjust the axial play somewhat compressed and thereby shortened axially; in the case of the before DE-GM 19 96 096 mentioned are each a thrust washer and a toothed washer is provided, against the thrust washer lying teeth are deformed using high pressure.  

Eine demgegenüber fertigungs und montagetechnisch einfachere und gleichzeitig betriebssichere Axialspieleinstellung ist erfindungsgemäß durch die Lehre des Anspruchs 1 bzw. des Anspruchs 2 möglich.In contrast, a simpler manufacture and assembly technology and at the same time is reliable axial play adjustment according to the invention by the teaching of claim 1 or Claim 2 possible.

Zweckmäßigerweise wird bei der Einstellung des Axialspiels durch einen plastischen Verformungsvorgang der Abstandshülse zur Kürzung von der Abstands-Überlänge auf die jeweilige Ab­ stands-Betriebslänge eine Erwärmungs-Erweichung des plastisch zu verformenden Bereichs der Abstandshülse vor bzw. während der Stauchverkürzung durch Ultraschall erreicht, wobei zweckmäßiger­ weise in die Stauchvorrichtung gleichzeitig die Erwärmungs- Vorrichtung, insbesondere in Form einer Ultraschall-Schweiß­ vorrichtung, integriert ist.It is useful when adjusting the axial play through a plastic deformation process of the spacer sleeve to shorten the excess distance to the respective Ab stand operating length a warming softening of the plastic area of the spacer sleeve to be deformed before or during the Compression shortening achieved by ultrasound, being more expedient into the upsetting device simultaneously the heating Device, in particular in the form of an ultrasonic welding device that is integrated.

Durch die erfindungsgemäße Kürzung durch Abtrennen bzw. pla­ stisches Verformen läßt sich bei einfachem Kürzungs-Ferti­ gungs- bzw. -Montagevorgang trotzdem eine kleinbauende und gleichzeitig eine Isolierabdeckung der Rotorwelle gegenüber gegebenenfalls durchhängenden Wicklungsdrähten zwischen der Rotorwicklung und dem angeschlossenen Kommutator gewährlei­ stender Axialspieleinstellung erreichen. Eine Anwendung eignet sich daher insbesondere für Kommutator-Kleinmotoren mit einer Axialspieleinstellung zwischen dem Rotor und lagerschildsei­ tigen Gleitlagern, die die Rotorwelle aufnehmen.Due to the inventive shortening by separating or pla tical deformation can be done with a simple shortening machine installation or assembly process is still a small and at the same time an insulating cover opposite the rotor shaft if necessary sagging winding wires between the Guarantee rotor winding and the connected commutator reach the axial play setting. One application is suitable is therefore particularly suitable for small commutator motors with a Axial play adjustment between the rotor and bearing plate term slide bearings that accommodate the rotor shaft.
