PTO gearbox

All power take-offs are particularly designed for traveling 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 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 gives opposite rotation. Power to the pump is not affected by the normal use 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 devices manufacturer, and should be properly safeguarded against overloading.
PRM power take-off devices fit on the rear face of the main gearcase and are driven by the insight shaft; consequently they can be operated at all times whilst the engine is pto gearbox running, The power take-off replaces the finish cover which is generally fitted 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 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’ll operate at all times when the engine is usually running, and since there is absolutely no clutch for disengagement of the hydraulic pump, provision should be manufactured in the auxiliary hydraulics circuits for pressure by-complete to the reservoir when power to the pump is not required. A pair of 1:1 ratio gears, providing enough offset between your gearbox result shaft and the centreline of the power take-off to make sure there is adequate clearance between your hydraulic pump and propeller shaft coupling.
