Abstract: A transfer mechanism is operatively disposed between a conveyor for dynamo-electric machine parts (such as electric motor armatures) and apparatus for simultaneously processing a plurality of those parts (e.g., by winding coils of wire on those parts). The transfer mechanism delivers processed parts to the conveyor and receives unprocessed dynamo-electric machine parts from the conveyor, one at a dime in a single alignment position, at least partly concurrent with the processing of other parts. Loss in production time due to wire breakage at the processing apparatus is reduced by substantially instantaneously controlling the broken wire (e.g., by retracting that wire relative to the associated wire dispenser) while continuing to move the wire dispensers.

Title: Kurbelwellenlagerung einer mehrzylindrigen Brennkraftmaschine
Inventor: MUDDEMANN MICHAEL
IPC: F16N31/02

Abstract: Die Kurbelwellenlagerung einer mehrzylindrigen Brennkraftmaschine hat ein oberes (2) und ein unteres Lagerteil (3) sowie damit verbundene obere und untere Lagerbrücken (6,7) mit Lagerbohrungen, in denen die Hauptlagerzapfen einer Kurbelwelle gelagert sind. Die Hauptlagerzapfen (4) der Kurbelwelle (5) werden über Ölrinnen in den Lagerbohrungen mit Schmiermittel versorgt. Um das aus den Lagerstellen austretende Öl, das durch die rotierenden Kurbelwellenwangen abgeschleudert wird, zu führen, sind an den Seitenflächen der Lagerbrücken Ölrinnen (17,18) ausgebildet, die an ihren radialen Innenseiten offen sind und einen in Einbaulage unteren Ablauf aufweisen. Damit wird ein starkes Verschäumen des Öls verhindert, da das von den Kurbelwellen abgeschleuderte Öl direkt aufgefangen und geführt wird. Die Verweildauer des Öls im Kurbelraum wird reduziert, so daß das Öl schneller zurück in die Ölwanne fließt und Planschverluste verringert werden. <IMAGE>
