Pronar T743 SECTION 3
3.12
Power transmission shaft (2) is connected through PTO shaft and articulated shaft to PTO of
tractor. Hydraulic clutch is located on drive shaft. Both transmission stages are working after
engaging PTO drive and after initiation of hydraulic clutch (1). The torque is transmitted via
gear wheels to intersecting axis gearing (4), which drives two auger conveyors mounted in
the front conveyor. Next, the torque is transmitted to further receivers – the collecting auger
conveyor (3) and two auger conveyors (divided) placed in container.
In upper part of gearing, on rear wall housing is placed the pressure gauge indicating actual
pressure of hydraulic oil conducted to hydraulic clutch.
IMPORTANT!
Oil pressure in hydraulic clutch may not be greater than 95 bar or less than 90 bar. Too
low power pressure causes slipping clutch and therefore more rapid wear of abrasive
surface, too high pressure may damage clutch body.
3.6 GEAR WHEEL TRANSMISSION
Front gear wheel transmission (1) is placed on the front wall of load box. Drive is transferred
to drive shaft (2) from front chain drive. Torque is directly transmitted to right front auger
conveyor placed in load box.
Gear transmission is equipped with lever a enabling change of setting. In lever setting
(B) high rotation is set for conveyors placed in container, position (C) reduces mechanism
RPM. Position (A) is neutral setting and may be used to remove blockages or thoroughly
clean the container channel.
