Description

Die Erfindung betrifft Druckluft-Motoren mit pfeilförmig verzahnten Läufern und hat eine vorteilhafte Gestaltung des Lufiteinlaßkanals zum-Gegenstand. Bisher hat man den EinlaB durch eine in der Gehäuselängsmi:tte senkrecht zur Ebene der Läuferachse angeordnete Bohrung mit kreisförmigem Querschnitt hergestellt, welche an dein von den beiden. Gehäusebohrungen gebildeten Grat entweder in zwei eiförmigen Durahbrüchem rechts und links- des. Grates einmündet oder mit ihrem ganzen Querschnitt beide Gehäusewandungen durchdringt. Jedenfalls ;sind diesle Durahdringungen in der A#bwicklung der Gehäusewand- von Kurven umgrenzt. Die Füllung der Zahnzellen wird beim Voribeigleiten der Zahnköpfe ziemlich stamk gedrosselt, weil die in der Abwicklung geradlinigen Zahnkanten diie Durchtritbsöffnung auf ein sich rasch verkleinerndes Segment beschränken.The invention relates to compressed air motors with arrow-shaped teeth Runners and has an advantageous design of the air inlet channel to the subject. So far, the inlet has been made through a longitudinal center of the housing perpendicular to the plane the rotor axis arranged bore made with a circular cross-section, which to yours of the two. Housing bores formed either in two egg-shaped ridge Durahbrüchem on the right and left of the ridge opens or with its entire cross-section penetrates both housing walls. In any case; are all these penetrations in the Development of the housing wall bordered by curves. The filling of the tooth cells becomes quite stamk throttled when the tooth tips slide past because they are in the process of being processed straight tooth edges the passage opening to a rapidly decreasing Restrict segment.

Die Erfindung beiabsiahtigt, den Einitrittsquerschnitt bis zur Beendigung der Füllung möglichst unverändert zu lassen und, dadurch die Drosselverluste zu verringern. Sie besteht darin, daß der Einlaßkanal wenigstens an seiner Einmündung in die sich überschneidenden Gehäusewände einen rhombischen Umriß .hat, wobei die eine Diagonale des Rhombus in dem Übersehneidüngsgrat der GehäusebohTungen, liegt und die Rhombenseiten para11el zu den über sie hinwegstreichenden Zahnkanten gerichtet sind.The invention assumes the entry cross section to the end to leave the filling as unchanged as possible and thereby reduce the throttling losses to decrease. It consists in that the inlet channel at least at its confluence in the intersecting housing walls a rhombic outline .hat, the a diagonal of the rhombus lies in the overlap ridge of the housing indentations and the sides of the rhombus directed parallel to the tooth edges sweeping over them are.

Versuche haben ergeben, daB Druckluft-Mutoren mit einem Lufteinlaßkanal 'nach der Erfindung .gegenüber einem Motor mit dem üblichen zylindrisahen EinlaBquerschnitt bei 4 atü Überdruck eine um io °/o höhere Leistung bei einem etwas geringeren spezifischen Luftverbrauch haben. Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in den Abbildungen dargestellt Es. zeigt Fig. r einen Querschnitt durch die beiden Rotorkörper und den darunterliegenden Einlaßkanal mit um .9o° geldapptem strichpunktiert gezeichnetem alten (runden) und neuen Querschnitt, Fig. 2 die Abwicklung des Kanalquerschnittes in Draufsicht mit darunterliegender Verzahnung. Die beiden über ihre pfeilförmige Verzahnung miteinander im Eingriff stehenden Rotork@rper i, 2 werden mittels Druckluft, die durch den Einlaßkanal 3 zuströmt, beaufsahlagt. Um die Druckverluste, die durch Drosselung in sich verengenden Einströmquerschnitten. entstehen, zu vermindern, besitzt der Einströmkanal3 einen rhonnbischen Querschnitt (Fig. i strichpunktiert gezeichnet) mit parallel zu den Zahnkanten der Rottoren i, 2 verlaufenden Rhombenseiten 45-6-7-4-Tests have shown that compressed air mutors with an air inlet duct According to the invention, compared to a motor with the usual inlet cross-section close to the cylinder at 4 atm overpressure a 10% higher output with a somewhat lower specific one Have air consumption. An embodiment of the subject matter of the invention is shown in Illustrations depicted it. Fig. r shows a cross section through the two rotor bodies and the inlet channel underneath with a dot-dash line drawn by .9o ° Geldappen old (round) and new cross-section, Fig. 2 the development of the channel cross-section in plan view with teeth below. The two about their arrow-shaped The interengaging Rotork @rperper i, 2 are by means of compressed air, which flows through the inlet channel 3, acted upon. To the pressure losses caused by Throttling in narrowing inflow cross-sections. arise, diminish, the inflow channel 3 has a Rhonnbian cross-section (Fig. i dash-dotted lines drawn) with rhomb sides running parallel to the tooth edges of the rotors i, 2 45-6-7-4-
