worm gear unit

Beginning with these considerations, we’ve a gearbox with a electric motor mounting flange that is separable from the housing which incorporate the essential oil seal; in this manner we avoid any threat of damaging the oil seal in the event of substitute of the input flange and the O-Ring could be eliminated.
All the apart covers, swinging and with ft, have O-Rings rather than traditional flat gaskets.
The sizes 03-04-05 allow the rotation of the feet without disassembling them; furthermore the versions with swinging aside covers permit the lateral flanges to end up being 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 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 within the catalogue of CHM) may also be mounted with this range, finding a gear ratio up to 1 1:300. For bigger worm gear unit reductions is possible to have two gears together using an appropriate kit
