All power take-offs are particularly designed for generating hydraulic pumps to SAE J744C series ‘B’ specification with splined insight 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 isn’t affected by the normal usage of the gearbox for propulsion duties. All ancillary power circuits driven by PRM power take-offs should be designed in accordance with the suggestions of the hydraulic equipment manufacturer, and really should be properly safeguarded against overloading.
PRM power take-off models fit on the rear face of the primary gearcase and are driven by the input shaft; consequently they could be operated all the time whilst the engine is usually running, The power take-off replaces the end cover which is generally fitted and performs the features of the finish cover by sealing the gearbox against loss of oil and properly positions the input shaft back bearing. Power take-off units 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 certainly driven directly from the gearbox input shaft; consequently it’ll operate all the time when the engine is operating, and since there is absolutely no clutch for disengagement of the hydraulic pump, provision should be made in the auxiliary hydraulics circuits for pressure by-pass to the reservoir when power to the pump is not needed. A couple of 1:1 ratio gears, providing enough offset between your gearbox output shaft and the centreline of the power take-off to make sure there is sufficient clearance between the hydraulic pump and propeller shaft coupling.
