Beginning with these considerations, we’ve a gearbox with a engine mounting flange that’s separable from the casing which incorporate the essential oil seal; in this manner we avoid any risk 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 ft, have O-Rings rather than traditional flat gaskets.
The sizes 03-04-05 allow the rotation of the feet without disassembling them; furthermore the versions with swinging apart covers worm gear unit permit the lateral flanges to become installed on both sides with simple 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 may come during the pressure of die-castings.
The CHPC pre-stage gears (already within the catalogue of CHM) may also be mounted with this range, finding a gear ratio up to 1 1:300. For larger reductions is possible to have two gears collectively using a proper kit
