Abstract

Axial play adjustment between the rotor and the stator-mounted bearings of an electric motor is effected by a plastics spacer sleeve which is pushed onto the rotor shaft and which can be shortened to the operative spacer length. The novelty is that the spacer sleeve is shortened by cutting off the excess spacer length or by plastic deformation of the sleeve. Also claimed is a similar process using an insulating end disc arranged at least at one front end of a rotor plate stack, the novelty being that the spacer sleeve is integrated with the insulating end disc, esp. as a one-piece plastics part. ADVANTAGE - Operationally reliable axial play adjustment is achieved in a simple manner.

Description

Die Erfindung bezieht sich auf ein Verfahren zur Einstellung des Axialspiels gemäß Oberbegriff des Anspruchs 1 bzw. des Anspruchs 2; ein derartiges Verfahren ist aus der EP-B1 01 75 798 bekannt.The invention relates to a method for adjustment of the axial play according to the preamble of claim 1 and the Claim 2; such a method is known from the EP-B1 01 75 798 known.

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 together with one operationally in front of a front of the Rotor laminated core arranged as an insulating washer lumpy injection molded spacer sleeve in front of her Push on or press on the rotor shaft with a tw target vulnerability in the form of over the circumference distributed tearable or breakable intermediate webs or with in shape over the circumference at a mutual radial distance hinge-like, leaving gaps, ela stisch yielding intermediate webs provided, whereby to the set the axial play either under pulling out or under elastic bending of the intermediate webs the bearing end the spacer sleeve on the insulating disc end of the Ab stand sleeve is axially displaced.

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, it is simpler in terms of production 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 vorgesehen. Diese Erwärmungs-Erweichung wird nach einer Ausgestaltung der Erfindung durch Ultraschall er­ reicht, wobei zweckmäßigerweise in die Stauchvorrichtung gleich­ zeitig die Erwärmungs-Vorrichtung, insbesondere in Form einer Ultraschall-Schweißvorrichtung, 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  Shrinkage provided. This warming softening will according to an embodiment of the invention by ultrasound is sufficient, expediently the same in the upsetting device timely the heating device, especially in the form of a Ultrasonic welding device 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.
