Starting from these considerations, we have a gearbox with a motor mounting flange that’s worm gear unit 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 can be eliminated.
All the apart covers, swinging and with feet, have O-Rings instead of traditional flat gaskets.
The sizes 03-04-05 allow the rotation of your toes without disassembling them; furthermore the versions with swinging apart covers allow the lateral flanges to become installed on both sides with basic fixing screws.
The worm screw includes a ZI involute profile: with this worm-wheel coupling we shall get a better performance with a temperature reduction.
The gearboxes and motors are painted with RAL 9022 aluminium colour epoxy powder to safeguard the parts from oxidation and against micro-blowholes that may 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, finding a gear ratio up to at least one 1:300. For bigger reductions is possible to possess two gears jointly using a proper kit
