worm gear unit

Starting from these considerations, we have a gearbox with a electric motor mounting flange that’s worm gear unit separable from the casing which incorporate the essential oil seal; in this way we avoid any risk of damaging the oil seal in the event of alternative of the insight flange and the O-Ring can be eliminated.
All the apart covers, swinging and with foot, have O-Rings rather than traditional flat gaskets.
The sizes 03-04-05 permit the rotation of your toes without disassembling them; furthermore the variations with swinging aside covers allow the lateral flanges to end up being fitted on both sides with simple 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) may also be mounted with this range, finding a gear ratio up to 1 1:300. For larger reductions is possible to possess two gears together using an appropriate kit
