we have a gearbox with a motor mounting flange that’s separable from the housing which incorporate the oil seal; in this way we avoid any risk of damaging the 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 ft, have O-Rings rather than traditional flat gaskets. The sizes 03-04-05 permit the rotation of the feet without disassembling them; furthermore the versions with swinging aside covers allow the lateral flanges to end up being fitted on both sides with simple repairing screws. The worm screw has a ZI involute profile: with this worm-wheel coupling we will get a better efficiency with a temperature decrease. The gearboxes and motors are painted with RAL 9022 aluminium color epoxy powder to protect the parts from oxidation and against micro-blowholes that can come through the pressure of die-castings. The CHPC CH WORM GEARED MOTORS AND WORM GEAR UNITS pre-stage gears (already within the catalogue of CHM) may also be mounted with this range, finding a gear ratio up to at least one 1:300. For bigger reductions can be done to possess two gears together using a proper kit
