Capacity
All power take-offs are specifically designed for traveling hydraulic pumps to SAE J744C series ‘B’ specification with splined insight shaft and either two-bolt or four-bolt fixing. The utmost power which can be transmitted is 22 KW (29.5 bhp) per 1000 rev/min engine speed; this compatible a torque of 209 Nm (155 Ibf.ft. – 21.33 kgm.).For PRM1000 the clutched power take-off provides pump rotation the same as the engine, where as the direct drive power take-off for the PRM500 and PRM750 will give opposite rotation. Capacity to the pump is not affected by the standard utilization of the gearbox for propulsion duties. All ancillary power circuits driven by PRM power take-offs should be designed in accordance with the recommendations of the hydraulic gear manufacturer, and should be correctly safeguarded against overloading.
Installation
PRM power take-off models fit on the rear face of the main gearcase and are driven by the input shaft; consequently they can be operated all the time whilst the engine is usually running, The energy take-off replaces the finish cover which is normally fitted and performs the features of the end cover by sealing the gearbox against loss of oil and properly positions the insight shaft rear bearing. Power take-off models also provide the link between the gearbox and the hydraulic pump.
Direct Drive Power Take-Off
On the PRM500 and PRM 750 the immediate drive power take-off is usually driven directly from the gearbox input shaft; consequently it will operate at all times when the engine is definitely working, and since there is no clutch for disengagement of the hydraulic pump, provision must be made in the auxiliary hydraulics circuits for pressure by-pass to the reservoir when power to the pump is not required. A set of 1:1 ratio gears, providing enough offset between the gearbox result shaft and the centreline of the energy take-off to make sure there is sufficient clearance between the hydraulic pump and propeller shaft coupling.
