Starting from these considerations, we’ve a gearbox with a electric motor mounting flange that’s separable from the casing which incorporate the oil seal; in this way we avoid any threat of damaging the oil seal in the event of replacement of the insight flange and the O-Ring could be eliminated.
All the aside covers, swinging and with foot, have O-Rings rather than traditional flat gaskets.
The sizes 03-04-05 permit the rotation of the feet without disassembling them; furthermore the versions with swinging apart covers allow the lateral flanges to become installed on both sides with simple fixing screws.
The worm screw includes a ZI involute profile: with this worm-wheel coupling we will get a better performance with a temperature worm gear unit 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) may also be mounted with this range, obtaining a gear ratio up to at least one 1:300. For bigger reductions is possible to possess two gears jointly using a proper kit
