摘要： A high horsepower motor and gear system is provided in which the motor has a hollow drive shaft and the first stage drive gear has a long shaft extending through the hollow drive shaft and fixedly attached thereto at its far end, the latter shaft being sufficiently resilient to absorb positional errors which would otherwise result in high dynamic load exerted between the first gear pair. The system permits reduction in gear size which would otherwise be required, close coupling and ease of alignment between the two mentioned shafts and between the first stage drive and driven gears, being particularly useful as the drive for an aerator impeller.
