CARDAN SHAFT DRIVE
• Use telescopic cardan shafts.
Fig. 3.4
• In order to achieve a uniform motion of the driven shaft, the
following requirements must be met:
- Equal working angle α and α1 of both couplings;
- The internal fork joints must be coplanar;
- Both driven and driving shafts must be coplanar.
• It is also recommended working with limited articulated joint angles
(max 15°) and disengaging the transmission for those operations
requiring great angles (steering or lifting).
BELT DRIVE
Fig. 3.5
• Install a suitable pulley on the smooth shaft as close as possible to
the pump: Max 40 mm (PR150) e Max 50 mm (PR200-250).
• Apply an adequate belt tension (T): 4000N (PR150), 4900N
(PR200) e 5300N (PR250).
• Do not use driven or driving pulleys with a pitch diameter inferior to
250mm. Small pulleys require a high belt tension which may cause
premature wear to the bearing or transmission troubleshooting.
• A limited speed ratio allows a longer belts life while reducing
stress on the shafts.
