worm gear unit

Beginning with these considerations, we have a gearbox with a engine mounting flange that is separable from the casing which incorporate the essential oil seal; in this manner we avoid any threat of damaging the oil seal in case of replacement of the insight 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 variations with swinging apart covers permit the lateral flanges to be fitted on both sides with basic fixing screws.
The worm screw includes a ZI involute profile: with this worm-wheel coupling we shall 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 may 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, finding a gear ratio up to at least one 1:300. For larger worm gear unit reductions is possible to possess two gears together using a proper kit
