Beginning with these considerations, we have a gearbox with a electric motor mounting worm gear unit flange that is separable from the housing which incorporate the essential oil seal; in this manner we avoid any threat of damaging the oil seal in case of replacement of the input flange and the O-Ring can be eliminated.
All the aside covers, swinging and with foot, have O-Rings instead of traditional flat gaskets.
The sizes 03-04-05 permit the rotation of the feet without disassembling them; furthermore the variations with swinging aside covers allow the lateral flanges to be fitted on both sides with basic fixing screws.
The worm screw has a ZI involute profile: with this worm-wheel coupling we will get a better performance with a temperature reduction.
The gearboxes and motors are painted with RAL 9022 aluminium colour epoxy powder to protect the parts from oxidation and against micro-blowholes that can come through the pressure of die-castings.
The CHPC pre-stage gears (already present in the catalogue of CHM) can also be mounted with this range, obtaining a gear ratio up to at least one 1:300. For bigger reductions is possible to have two gears jointly using an appropriate kit
