Hydraulic PTO Gearbox
P.T.O TRACTOR GEARBOXES
The gearboxes series are used mainly for connecting hydraulic pumps to the power take-offs of agricultural tractors. PTO output, standardized at either 540 or 1,000 rpm, is, in this way, increased to optimum operating speeds for the hydraulic pumps. RD series of gearboxes are used to reduce hydraulic motor speed.
ML and B series gearboxes provide the connection for hydraulic pumps to low speed tractor power take off. The standard power take off speed of 540 rpm, is increased by the gearbox ratio to optimal speed conditions required for the pump. Different inputs are accepted under condition that the output speeds don’t go over 3000 rpm.
hydraulic PTO driven gearbox for tractor
The Gearboxes are designed for connecting gear pumps to farm tractor power take offs (PTO). Output speed of power take offs is 540rpm which can be compared with the proper running speeds of hydraulic pumps. Different input running speeds can also be suitable,provided that the gearbox output speed does not exceed 3000 rpm.
Housing
Made in shell-cast aluminum or in high mechanical resistance cast iron.
Gears
Made in Steel UNI 18 PCR M03.Stub teeth guarantee very high resistance and run very quietly.
Shafts
Made in steel UNI 16 CRN4.They are coupled with gears via splined parts and are thus more suitable to stand the torques stated in the catalogue.
Torques
The torque figures mentioned in the technical charts of all the PTO Gearboxes refer to continuous duty cycles. Torques under intermittent working conditions can be exceeded by 20%.
Lubrication
SAE 90 gear oil must be put in the pto gearbox prior to use-please note we do not supply the gear oil and will not accept responsibility for customers not putting oil in. Change the oil after the first 60-80 hours and then every 12 months or 1500 hours which ever falls first.
Maintenance
Please check the oil level via the special oil window every 50 hours. Working temperatures should not exceed 120 degrees celcius under continuos duty cycle.
Pump assembly
Pump assembly requires a half-coupling and a fitting flange according to specific requirements,when ordering please specify flange and pump shaft type.Contact our technical staff when installing special pumps.
