ABSTRACT:
A heating oven for use in dynamo-electric machine component manufacture is provided. The oven uses forced air heating to raise the temperature of in-process component subassemblies to suitable process temperatures. The heating oven includes a rotating drum mounted in a cabinet. A number of open-ended tubular cradles are disposed in circular arrays between the drum faces. Batches of component subassemblies may be individually loaded into the cradles for heat treatment. Air flow channels are set up in the oven cabinet to evenly distribute heated air through individual cradles. Heated air after passing over the individual in-process subassemblies, exits the cradles through side slots in the cradle walls into the interior of the drum. The exiting air is reheated and recirculated through the heating oven.
