Abstract

The invention relates to a hollow shaft for transmitting torques, with teeth and bearings, the hollow shaft having ribs or protrusions for reinforcement radially to the inside or radially to the outside in the longitudinal direction in order to be able to meet relatively high requirements as regards torsional and bending moments. The height or number of the longitudinal ribs or protrusions for reinforcing the hollow shaft are matched in an optimum manner to the requirements over the circumference of the hollow shaft.

Description

"Hohlwelle mit in Längsrichutng angebrachten Versteifungs-"Hollow shaft with stiffening in the longitudinal direction

rippen" Die Erfindung bezieht sich auf eine Hohlwelle nach dem Oberbegriff des Anspruches 1. rib "The invention relates to a hollow shaft according to the preamble of claim 1.

Es ist bekannt, Hohlwellen insbesondere gestufte Iohiweilen durch Umformverfahren zu erstellen, wobei Drehmomentübertragungen in der Welle selbst durch Verzahnungen verschiedene Module stattfinden.It is known to use hollow shafts, in particular stepped shafts Create forming processes, with torque transmissions in the shaft itself different modules take place through toothing.

Die Drehmomentübertragung kann selbstverständlich auch durch mit der Welle festverbundende Konstruktionselemente erfolgen.The torque transmission can of course also by using the Shaft firmly connected construction elements.

Zwischen den Angriffspunkten für die Drehmomentübertragung ist die hohlwelle auf Torsion und auf Biegung beansprucht.Between the points of application for torque transmission is the hollow shaft subjected to torsion and bending.

Zwischen diesen Angriffspunkten und einer Lagerstelle ist die Hohlwelle im wesentlichen auf Biegung beansprucht.The hollow shaft is between these points of application and a bearing point essentially subjected to bending.

Diese Torsions- bzw. Biegungs-Beanspruchung ist um so größer, je größer die Durchmesserunterschiede und die Lagerabstände zwischen den Angriffspunkten sind.This torsional or bending stress is greater, the greater are the diameter differences and the bearing distances between the points of application.

Bei.einer Welle aus Vollmaterial wird die Beanspruchung im allgemeinen unerheblich sein; jedoch bei einer Ubertragung von Drehmomenten bei Hohlwellen kann die Beanspruchung kritisch werden. Nicht nur aus Kostengründen, sondern vielmehr noch um drehmoment-Ubertragende Hohlwellen mit möglichst niedrigem Gewicht einzusetzen, wird man bestrebt sein, die Wandstarken der Hohlwellen niedrig zu halten.In the case of a shaft made of solid material, the load is generally higher be irrelevant; however, in the case of a transmission of torques in the case of hollow shafts the stress becomes critical. Not just for cost reasons, but much more still to use torque-transmitting hollow shafts with the lowest possible weight, one will strive to keep the wall thickness of the hollow shafts low.

Die vorliegende Erfindung hat sich die Aurgabe gestellt, eine Hohlwelle zu Ubertragung von Drehmomenten, möglichst kostenniedrig, und durch möglichst geringe Wandstärken mit niedrigem Oewicht zu erstellen, die einmal der große der Drehmomentübertragung und einem Durchmesserunterschied der Angriffspunkte optimal angepasst werden kann.The present invention was based on the gift of a hollow shaft for the transmission of torques, as inexpensively as possible, and by as little as possible To create wall thicknesses with low Oewicht, which is once the great torque transmission and can be optimally adapted to a difference in diameter of the points of application.

Dies wird mit den kennzeichnenden Merkmalen des Anspruches 1 erreicht.This is achieved with the characterizing features of claim 1.

Durch die Anbringung von Verstärkungsrippen an einer EIohlwelle, entweder radial außen oder radial innen, entweder über hochbeanspruchte Teile der Hohlwelle oder über die gesamte Hohlwelle in Längsrichtung ist es möglich, die Welle optimal an große Anforderungen bei der Drehmomentübertragung, oder bei großen Durchmesserunterschieden der Angriffspunkte, sowie bei großen Lagerabständen der Welle anzupassen; und zwar mit geringem Materialaufwand, das heißt ohne daß die Wandstärke der Hohlwelle selbst verstärkt werden muß.By attaching reinforcing ribs to a hollow shaft, either radially outside or radially inside, either via highly stressed parts of the hollow shaft or over the entire hollow shaft in the longitudinal direction, it is possible to optimize the shaft for high demands on torque transmission, or for large differences in diameter adapt the points of application as well as the shaft in the case of large bearing distances; in fact with little material expenditure, i.e. without reducing the wall thickness of the hollow shaft itself needs to be reinforced.

Das bedeutet mit anderen Worten daß das Gewicht der Hohlwelle jeweils auf ein Minimum eingestellt werden kann.In other words, this means that the weight of the hollow shaft in each case can be set to a minimum.

Nach einem weiteren Merkmal werden die Längsrippen an der Hohlwelle zwischen Drehmoment- oder Biege-Momentangriffspunkten angeordnet. Insbesondere bei großen Durchmesserunterschieden der Verzahnungen und großen Abständen der Verzahnungen untereinander sowie zwischen Verzahnung und Lagerstelle können erhebliche Torsions- und Biege-Momente auftreten, die sich wowohl in Längs- wie auch in Durchmesser-Richtung der Hohlwelle bemerkbar machen.According to a further feature, the longitudinal ribs on the hollow shaft arranged between torque or bending moment application points. Especially with large differences in diameter of the gears and large distances between the gears with each other and between the toothing and the bearing point, considerable torsional and bending moments occur, both in the longitudinal as well as in the diameter direction make noticeable of the hollow shaft.

Man wird also je nach Erfordernis für hochbeanspruchte Längsabschnitte die Hohlwelle mit einer größeren Anzahl Rippen über den Hohlwellendurchmesser verteilt, oder radial nach außen oder radial nach innen höhere Rippen anbringen.So you will, depending on the requirements, for highly stressed longitudinal sections the hollow shaft with a larger number of ribs distributed over the hollow shaft diameter, or add higher ribs radially outwards or radially inwards.

Nach einem weiteren Merkmal sind die radial außen angebrachten Längsrippen bzw, Ausbuchtungen mit der Hohlwelle zusammen, umgeformt.According to a further feature, the longitudinal ribs attached radially on the outside or, bulges with the hollow shaft together, reshaped.

Die radial innen angebrachten Längsrippen sind zweckmäßigerweise durch das Herunterwalzen von Ausbuchtungen radial nach außen auf beispielsweise den ursprünglichen Durchmesser gebildet.The longitudinal ribs attached radially on the inside are expediently through rolling down bulges radially outward onto, for example, the original one Diameter formed.

Nach einem weiteren Merkmal weisen die Ausbuchtungen im wesentlichen die gleiche Wandstärke auf, wie die Hohlwelle selbst.According to a further feature, the bulges essentially have the same wall thickness as the hollow shaft itself.

Nachfolgend wird an iland der beigefügten Zeichnung ein bevorzugtes Ausführungsbeispiel nach der Erfindung näher erläutert.In the following, a preferred one is given in conjunction with the attached drawing Embodiment according to the invention explained in more detail.

In der Zeichnung zeigen: Fig. 1 den Querschnitt durch eine Hohlwelle mit Ausbuchtungen bzw. Rippen radial nach außen und Fig. 2 den Querschnitt durch eine Hohlwelle mit Längsrippen radial nach innen.In the drawing: FIG. 1 shows the cross section through a hollow shaft with bulges or ribs radially outwards and FIG. 2 shows the cross section through a hollow shaft with longitudinal ribs radially inwards.

In der Figur 1 zeigt 1 die Wandstärke der Hohlwelle selbst, und 2 zeigt Ausbuchtungen bzw. Rippen radial nach außen, wahrend Figur 2 radial nach innen gerichtete Rippen 3 zeigt. Die Schnitte der Hohlwelle sind gezeigt an Stellen an denen keine Verzahnung, keine Lagerstellen bzw. andere angebrachte Konstruktionselemente vorhanden sind.In FIG. 1, 1 shows the wall thickness of the hollow shaft itself, and 2 shows bulges or ribs radially outwards, while Figure 2 shows radially inwards directed ribs 3 shows. The sections of the hollow shaft are shown at points which have no teeth, no bearing points or other attached construction elements available.
