Beginning with these considerations, we’ve a gearbox with a engine mounting flange that’s separable from the housing which incorporate the oil seal; in this manner we avoid any threat of damaging the oil seal in case of replacement of the input flange and the O-Ring can be eliminated.
All the aside covers, swinging and with feet, have O-Rings rather than traditional flat gaskets.
The sizes 03-04-05 allow the rotation of your toes without disassembling them; furthermore the variations with swinging apart covers allow the lateral flanges to be fitted on both sides with simple fixing screws.
The worm screw includes a ZI involute profile: with this worm-wheel coupling we will get a much better worm gear unit 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 can come during the pressure of die-castings.
The CHPC pre-stage gears (already within the catalogue of CHM) can also be mounted with this range, obtaining a gear ratio up to 1 1:300. For larger reductions is possible to have two gears together using a proper kit
