These add on units have
been design to be able to
increase the overall gearing
range of the CHM Design of
Worm Gear Units that have
the same dimensions of the
Motorvario NMRV040- 130
series worm units by coupling
a 3-1 ratio Pre-Stage Helical
Spur unit CHPC similar to the
PC-NMRVseries Motovario
range although with some
minor dimensional changes
so as to provide a sealed modular unit which can be supplied complete with a Motor or as a Pam type with a Hollow Input shaft and motor flange!
