Beginning with these considerations, we’ve a gearbox with a engine mounting flange that’s separable from the housing which incorporate the essential oil seal; in this way we avoid any risk of damaging the oil seal in case of alternative of the input flange and the O-Ring can be eliminated.
All the apart covers, swinging and with foot, have O-Rings instead of traditional flat gaskets.
The sizes 03-04-05 allow the rotation of your toes without disassembling them; furthermore the variations with swinging aside covers permit the worm gear unit 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 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 during 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 together using a proper kit
