worm gear unit

Starting from these considerations, we have a gearbox with a engine mounting flange that’s worm gear unit separable from the housing which incorporate the essential oil seal; in this manner we avoid any risk of damaging the essential oil seal in case of replacement of the insight flange and the O-Ring can 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 toes without disassembling them; furthermore the versions with swinging apart covers permit the lateral flanges to end up being installed on both sides with simple fixing screws.
The worm screw has a ZI involute profile: with this worm-wheel coupling we shall get a better performance with a temperature reduction.
The gearboxes and motors are painted with RAL 9022 aluminium colour epoxy powder to safeguard the parts from oxidation and against micro-blowholes that may come during the pressure of die-castings.
The CHPC pre-stage gears (already present in 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 have two gears collectively using a proper kit
