ABSTRACT:
A drive mechanism lubricating system which includes a lubricating medium storage tank and an oil reservoir arranged at the drive mechanism for accommodating a predetermined quantity of lubricating medium. A first pump is arranged at the drive mechanism for constantly replenishing the oil reservoir with a supply of lubricating medium to maintain a predetermined quantity therein during an operation of the drive mechanism. A second pump, having a higher conveying power than the first pump, is arranged at the drive mechanism and operatively connects the oil reservoir with the storage tank for conveying excess lubricating medium from the reservoir to the storage tank. A monitoring construction is arranged in a delivery conduit of the second pump for monitoring the condition of the lubricating medium and providing an output signal upon a failure in a return flow of the lubricating medium, with the output signal from the monitoring construction triggering a warning device to indicate the failure in the lubricating system. An additional pump is provided for supplying lubricating medium from the reservoir to lubricating points of the drive mechanism with a monitoring construction being arranged in conduits from the additional pump to monitor the operative condition of the pump and provide a signal indicative of a failure of such pump.
