worm gear unit

Starting from these considerations, we’ve a gearbox with a electric motor mounting flange that is separable from the casing which incorporate the oil seal; in this way we avoid any risk of damaging the essential oil seal in case of substitute of the input flange and the O-Ring could be eliminated.
All the apart covers, swinging and with foot, have O-Rings rather than traditional flat worm gear unit gaskets.
The sizes 03-04-05 permit the rotation of your feet without disassembling them; furthermore the variations with swinging aside covers allow the lateral flanges to be fitted on both sides with simple fixing screws.
The worm screw has 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 within the catalogue of CHM) may also be mounted with this range, obtaining a gear ratio up to 1 1:300. For bigger reductions is possible to possess two gears jointly using an appropriate kit
