A particular application for a 45 kW industrial diesel engine requires a steady crankshaft speed of 2800
revs/min. At the front end of the engine is a power take-off shaft. The shaft is shown in the accompanying
drawing. It has a standard splined shaft end and is fully supported in the engine structure.
I am required to design a power take-off gear reduction unit which can be easily fitted to the engine to
be driven by the above shaft. The unit is required to drive a hydraulic pump which must
deliver 25 litre/min of oil at 150-bar pressure.
Any help on how to approach the problem would be much appreciated.
