Abstract
A speed reduction unit (16, 17) is arranged between the driving shaft (4) of a starting motor (1) and a transmission shaft (20) which carries a moving transmission (39 to 42, 29) provided with a starting pinion (31). The crown (17) of the reduction unit is of a one piece type with the bearing sleeve (18) provided with a quick pitch threading (19), and is mounted on the shaft (20). The driving lug (26) of the free wheel (31) is mounted on the quick pitch threading (19) so as to reduce the overall size. A casing (51) surrounding the crown (17) is arranged between the intermediary bearing (20, 53) and the driving bearing (10, 54) and forms a lubricant-tight barrier between the reduction unit (16, 17) and the inside of the driving bearing (10).
Description
Andrehvorrichtung für Brennkraftmaschinen Starting device for internal combustion engines
Stand der TechnikState of the art
Die Erfindung geht von einer Andrehvorrichtung für Brennkraftmaschinen nach der Gattung des Anspruchs 1 aus. Bei einer solchen bekannten Andrehvorrichtung ist das Hohlrad des Stirnradvorgeleges für sich ausgebildet und auf der Getriebevelle anschließend an einen Steilgewindeabschnitt formschlüssig über eine Geradverzahnung auf der Getriebevelle. befestigt. Dabei ist von Nachteil, daß die Verbindung Hohlrad mit Getriebevelle verhältnismäßig schvach ausgebildet ist und das Hohlrad nur eine, verhältnismäßig kurze Sitzlänge auf der Getriebevelle hat, vodurch die Gefahr vorzeitigen Verschleißes durch Brechen und Verkannten gegeben ist. Weiterhin ist ein Stirnradvcrgelege bekannt, dessen Hohlrad mit einem Lageransatz versehen ist. Das Hohlrad mit dem Lageransatz ist zwar auf die Getriebevelle gepreßt. Die Preßverbindung zwischen Hohlrad und Getriebevelle reicht jedoch nur zur Übertragung eines bestimmten maximalen Drehmoments aus. Wird das maximale Drehmoment überschritten, drehen sich Hohlrad und Getriebevelle mit verschiedenen Drehzahlen. Das wird zwar als Stoßdämpfung genützt. Von Nachteil ist jedoch die längere Bauveise, veil sich erst an den Befestigungsbereich für den Lageransatz des Hohl
rades der Steilgevindeabschnitt der Getriebevelle anschließen kann, auf dem der Mitnehmer des Freilaufs sitzt.The invention is based on a starting device for internal combustion engines according to the preamble of claim 1. In such a known starting device, the ring gear of the spur gear is designed for itself and on the gear shaft after a steep thread section with a positive toothing on the gear shaft. attached. The disadvantage here is that the connection ring gear with gear shaft is relatively weak and the ring gear has only a relatively short seat length on the gear shaft, which gives rise to the risk of premature wear due to breaking and misjudging. Furthermore, a spur gear transmission is known, the ring gear of which is provided with a bearing attachment. The ring gear with the bearing boss is pressed onto the gear shaft. However, the press connection between the ring gear and the transmission shaft is only sufficient to transmit a certain maximum torque. If the maximum torque is exceeded, the ring gear and gear shaft rotate at different speeds. This is used as shock absorption. A disadvantage, however, is the longer construction, which only applies to the fastening area for the bearing shoulder of the hollow Rades the steep section of the gear shaft can connect, on which the driver of the freewheel sits.
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Andrehvorrichtung für Brennkraftmaschinen mit den kennzeichnenden Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, daß das mit der Hülse einteilig ausgebildete Hohlrad eine lange Führungslänge auf einer verhältnismäßig dünnen und somit materialsparenden Getriebevelle hat, mit der es nicht fest verbunden sein muß, veil es zugleich den Steilgevindeabschnitt aufweist. Dadurch wird eine verkürzte Baulänge der Andrehvorrichtung ermöglicht und die dünne Getriebevelle nicht als Drehmoment übertragendes Teil benötigt.The starting device according to the invention for internal combustion engines with the characterizing features of claim 1 has the advantage that the ring gear formed in one piece with the sleeve has a long guide length on a relatively thin and thus material-saving gear shaft with which it does not have to be firmly connected, veil it at the same time has the steep section. This enables a shorter overall length of the starting device and the thin transmission shaft is not required as a torque-transmitting part.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen der im Anspruch 1 angegebenen Andrehvorrichtung möglich. Besonders vorteilhaft ist durch die Ausbildung des Holrades mit Steilgevindehülse als Fließpreßteil oder Spritzteil aus Kunststoff die Verringerung der Zahl der Einzelteile und somit der Montagekosten. Darüberhinaus läßt sich bei der raumsparenden Ausbildung und Anordnung das Vorgelege mit einfachen Mitteln schmiermitteldicht machen.The measures listed in the subclaims allow advantageous developments of the starting device specified in claim 1. The reduction in the number of individual parts and thus the assembly costs is particularly advantageous due to the design of the Holrades with Steilgevindehülse as an extrusion or molded part made of plastic. In addition, the lay-up can be made lubricant-tight with simple means in the space-saving design and arrangement.
