Beginning with these considerations, we have a gearbox with a motor mounting flange that is separable from the casing which incorporate the oil seal; in this way we avoid any threat of damaging the essential oil seal in the event of alternative of the insight flange and the O-Ring can be eliminated.
All the aside covers, swinging and with foot, have O-Rings worm gear unit instead of traditional flat gaskets.
The sizes 03-04-05 permit the rotation of your feet without disassembling them; furthermore the versions with swinging apart covers permit the lateral flanges to end up being fitted on both sides with basic fixing screws.
The worm screw has a ZI involute profile: with this worm-wheel coupling we shall get a much 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 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 1 1:300. For larger reductions is possible to possess two gears collectively using a proper kit
