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 may be transmitted is usually 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 gives 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 normal 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 equipment manufacturer, and really should be properly safeguarded against overloading.
PRM power take-off products fit on the trunk face of the main gearcase and are driven by the input shaft; consequently they can be operated at all times whilst the engine is usually running, The energy take-off replaces the end cover which is normally installed and performs the features of the finish cover by sealing the gearbox against lack of oil and properly positions the input shaft back bearing. Power take-off devices provide the link between the gearbox and the hydraulic pump.
Direct Drive Power Take-Off
Available on the PRM500 and PRM 750 the immediate drive power take-off is driven directly from the gearbox input shaft; consequently it will operate at all times when the engine can be working, and since there is absolutely no clutch for disengagement of the hydraulic pump, provision must be manufactured in the auxiliary hydraulics circuits for pressure by-move to the reservoir when power to the pump is not required. A pair of 1:1 ratio gears, providing sufficient offset between the gearbox result shaft and the centreline of the energy take-off to ensure there is enough clearance between the hydraulic pump and propeller shaft coupling.
