Easy maintenance gearbox series
Bonfiglioli has developed the FDK and FZP versions of its 300 Series planetary gearbox. The 300 Series is a robust and versatile solution suited for harsh applications where shock loadings and impacts are expected.
The FDK and FZP versions feature hollow shafts which are said to offer easier and safer assembling/disassembling of the drive and make the series more effective and suitable for shaft mount assembly. Furthermore, the design of the shrink disk is claimed to improve and speed set up and give easier, more accurate screw tightening.
Another design component of the 300 series is the splined hollow shaft which meets the DIN 5480 standard and offers the same strong bearings available in the current FP version. It provides double cantering for an aligned assembling of the solid shaft of the machine. Like the keyed hollow shaft, the splined hollow shaft also includes an axial locking key with threaded holes for easier mounting and grants full rated and max torque transmissions.
With a torque range of 1,000 to 1,287,000Nm and gear ratios of 3.4 to 5,234, the 300 series is effective for shaft mounted requirements for all sizes and ratios.
