worm gear unit

Starting from these considerations, we have a gearbox with a engine mounting flange that is separable from the casing which incorporate the oil seal; in this manner we avoid any threat of damaging the essential 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 foot, have O-Rings instead of traditional flat gaskets.
The sizes 03-04-05 permit the rotation of your toes without disassembling them; furthermore the variations with swinging aside covers permit the lateral flanges to end up being installed on both sides with basic 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 protect 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) can also be worm gear unit mounted with this range, finding a gear ratio up to 1 1:300. For bigger reductions is possible to have two gears collectively using an appropriate kit
