Beginning with these considerations, we’ve a gearbox with a motor mounting flange that’s separable from the worm gear unit casing which incorporate the oil seal; in this manner we avoid any risk of damaging the essential oil seal in the event of substitute of the insight flange and the O-Ring can be eliminated.
All the apart covers, swinging and with feet, have O-Rings rather than traditional flat gaskets.
The sizes 03-04-05 allow the rotation of your feet without disassembling them; furthermore the variations with swinging aside covers allow the lateral flanges to be installed on both sides with basic fixing screws.
The worm screw includes 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 protect 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) may also be mounted with this range, obtaining a gear ratio up to at least one 1:300. For larger reductions can be done to possess two gears together using a proper kit
