Freiausstoßender Starter
Stand der Technik Free-ejection starter
State of the art

Die Erfindung betrifft eine verbesserte Lagerung der Ritzelwelle am vorderen Lagerschild eines freiausstoßenden Starters für Brennkraftmaschinen. Für solche Fälle werden heute bei größeren Starterleistung Wälzlager verwendet, siehe EP-B-O 518 895 (R. 23283), bei kleineren Leistungen werden Gleitlager gemäß DE-A-41 27 742 (R. 24620) verwendet, wobei zur Geräuschminderung Kunststoffbüchsen bevorzugt eingesetzt werden.The invention relates to an improved bearing for the pinion shaft on the front bearing plate of a free-ejection starter for internal combustion engines. In such cases, rolling bearings are used today for higher starter power, see EP-B-O 518 895 (R. 23283), for lower power, plain bearings according to DE-A-41 27 742 (R. 24620) are used, with plastic bushings being preferred for noise reduction.

Gemäß dem Vorschlag der vorliegenden Erfindung wird nunmehr bei freiausstoßenden Startern für das vordere Lager ein Nadellager ohne Innenring vorgeschlagen, d.h. daß die Nadeln in einer Lagerhülse beidseitig gegen Axialverschieben gesichert sind und direkt auf einem gehärteten Ritzelschaft laufen, wobei die Lagerhülse in eine Lagerbohrung des vorderen Lagerflansches eingesetzt ist. Diese Lösung ist wesentlich 0 kostengünstiger als Kugellager und beansprucht durch den kleineren Lagerdurchmesser weniger Platz beim Einbau des Starters in Kraftfahrzeuge.According to the proposal of the present invention, a needle bearing without an inner ring is now proposed for the front bearing in free-ejection starters, i.e. the needles are secured on both sides in a bearing sleeve against axial displacement and run directly on a hardened pinion shaft, with the bearing sleeve being inserted into a bearing bore in the front bearing flange. This solution is significantly less expensive than ball bearings and, due to the smaller bearing diameter, takes up less space when installing the starter in motor vehicles.

Ein Nadellager ist vor allem dann vorteilhaft am Ritzelschaft zu verwenden, wenn der Starter ein PlanetengetriebeA needle bearing is particularly advantageous to use on the pinion shaft if the starter has a planetary gear

R. 31628R.31628

mit einem elastischen Zwischenlager hat. Zur Abdichtung gegen Staub, Feuchtigkeit und dergleichen ist an der Stirnseite des Lagerflansches die Lagerbohrung mit einer Staubabdichtung versehen, die in einer ringförmigen Aussparung der Lagerbohrung eingesetzt ist und mit einer Dichtlippe am Ritzelschaft anliegt.with an elastic intermediate bearing. To seal against dust, moisture and the like, the bearing bore is provided with a dust seal on the front side of the bearing flange, which is inserted in an annular recess in the bearing bore and rests against the pinion shaft with a sealing lip.

Die Figur zeigt einen solchen Starter für Kraftfahrzeuge im Längsschnitt mit dem Nadellager und der Abdichtung am vorderen Lagerschild und dem elastischen Zwischenlager des Planetengetriebes. The figure shows such a starter for motor vehicles in longitudinal section with the needle bearing and the seal on the front bearing plate and the elastic intermediate bearing of the planetary gear.

Freiausstoßender Starter zum Andrehen von Brennkraftmaschinen in Kraftfahrzeugen mit einem vorderen Lagerschild, in dessen Lagerbohrung ein Lager zur Aufnahme eines Ritzelschaftes eingesetzt ist, wobei der Ritzelschaft am vorderen Ende ein Einspurritzel trägt und am hinteren Ende einen Einspurmechanismus mit einem elektrischen Andrehmotor verbunden ist, dadurch gekennzeichnet, daß das Lager für den Ritzelschaft ein Nadellager ist, dessen Nadeln unmittelbar auf einem gehärteten Bereich des Ritzelschaftes aufliegen.1. Free-ejection starter for starting internal combustion engines in motor vehicles with a front bearing plate, in the bearing bore of which a bearing is inserted to accommodate a pinion shaft, the pinion shaft carrying a meshing pinion at the front end and a meshing mechanism connected to an electric starting motor at the rear end, characterized in that the bearing for the pinion shaft is a needle bearing, the needles of which rest directly on a hardened area of the pinion shaft. 2. Freiausstoßender Starter nach Anspruch 1, dadurch gekennzeichnet, daß die Lagerbohrung vor dem Nadellager einen Abdichtring trägt, der mit einer nach innen gerichteten Dichtlippe am Ritzelschaft anliegt.2. Free-ejection starter according to claim 1, characterized in that the bearing bore in front of the needle bearing carries a sealing ring which rests against the pinion shaft with an inwardly directed sealing lip. 3. Freiausstoßender Starter nach Anspruch 1, dadurch gekennzeichnet, daß der Ritzelschaft über ein Planetengetriebe mit einem elastischen Zwischenlager mit dem Andrehmotor gekoppelt ist.3. Free-ejection starter according to claim 1, characterized in that the pinion shaft is coupled to the starting motor via a planetary gear with an elastic intermediate bearing.
