Mechanical power transmission system having improved lubricant circulation apparatus

摘要

A transmission system for transmitting mechanical power from a source of mechanical power to a power consuming load. The transmission system generally includes a controlled start transmission device or the like having an input shaft operatively connected to the source of mechanical power and an output shaft operatively connected to the power consuming load. Lubricant circulation apparatus are also provided to circulate and cool lubricant fluid maintained in a sump defined by the transmission device. Such lubricant circulation apparatus includes a centrifugal pump configured and mounted to remove air present in the circulating lubricant fluid. The pump is preferably mounted adjacent the transmission device upon a rigid fluid passage conduit.
