Abstract
The present invention is directed to a pump arrangement for use in a gear box housing. The interior surface of the gear box housing has a collection wall arranged in the interior surface of the housing. A shaft is rotatably disposed through the gear box housing and has a longitudinal bore extending through the shaft that provides a lubrication delivery arrangement for distributing lubricant through the gear box housing. A pump housing circumscribes the shaft and has a discharge cavity connected to the longitudinal bore. Additionally, the pump housing has an inlet port for receiving lubrication from the collection wall. Contained within the pump housing is a pump member that has an impeller face and helical threaded surface that pressurizes and introduces the lubricant into the lubricant delivery arrangement.
