worm gear unit

Beginning with these considerations, we’ve a gearbox with a motor mounting flange that is separable from the casing which incorporate the oil seal; in this way we avoid any threat of damaging the oil seal in the event of substitute of the input flange and the O-Ring can be eliminated.
All the aside covers, swinging and with ft, have O-Rings instead of worm gear unit traditional flat gaskets.
The sizes 03-04-05 permit the rotation of the feet without disassembling them; furthermore the variations with swinging aside covers allow 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 can come through 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 have two gears together using an appropriate kit
