worm gear unit

Beginning with these considerations, we have a gearbox with a motor mounting worm gear unit flange that’s separable from the casing which incorporate the essential oil seal; in this way we avoid any threat of damaging the oil seal in the event of alternative of the insight flange and the O-Ring could be eliminated.
All the aside covers, swinging and with foot, have O-Rings instead of traditional flat gaskets.
The sizes 03-04-05 allow the rotation of your toes without disassembling them; furthermore the versions with swinging aside covers allow the lateral flanges to be fitted on both sides with basic fixing screws.
The worm screw has 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) can also be mounted with this range, finding a gear ratio up to at least one 1:300. For larger reductions is possible to possess two gears collectively using an appropriate kit
