Starting from these considerations, we have a gearbox with a electric motor mounting flange that is 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 replacement of the input flange and the O-Ring could be eliminated.
All the apart covers, swinging and with feet, have O-Rings rather than traditional flat gaskets.
The sizes 03-04-05 permit the rotation of your feet without disassembling them; furthermore the versions 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 shall 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 worm gear unit pre-stage gears (already present in the catalogue of CHM) can also be mounted with this range, obtaining a gear ratio up to 1 1:300. For bigger reductions can be done to possess two gears together using an appropriate kit
