Capacity
All power take-offs are particularly designed for driving hydraulic pumps to SAE J744C series ‘B’ specification with splined input shaft and either two-bolt or four-bolt fixing. The maximum power which can be transmitted is definitely 22 KW (29.5 bhp) per 1000 rev/min engine speed; this equates to 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 gives opposite rotation. Capacity to the pump isn’t affected by the normal utilization of the gearbox for propulsion duties. All ancillary power circuits driven by PRM power take-offs ought to be designed in accordance with the suggestions of the hydraulic tools manufacturer, and should be properly safeguarded against overloading.
Installation
PRM power take-off products fit on the rear face of the main gearcase and so are driven by the insight shaft; consequently they can be operated at all times whilst the engine is running, The energy take-off replaces the end cover which is generally installed and performs the functions of the end cover by sealing the gearbox against loss of oil and correctly positions the input shaft back bearing. Power take-off units also provide the link between the gearbox and the hydraulic pump.
Direct Drive Power Take-Off
Available on the PRM500 and PRM 750 the direct drive power take-off is driven directly from the gearbox insight shaft; consequently it will operate all the time when the engine is 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 capacity to the pump is not required. A set of 1:1 ratio gears, providing adequate offset between the gearbox output shaft and the centreline of the energy take-off to ensure there is sufficient clearance between the hydraulic pump and propeller shaft coupling.
