we’ve a gearbox with a motor mounting flange that’s CH WORM GEARED MOTORS AND WORM GEAR UNITS separable from the housing which incorporate the oil seal; in this way we avoid any threat of damaging the essential oil seal in the event of replacement of the insight flange and the O-Ring could be eliminated. All the apart covers, swinging and with ft, have O-Rings rather than traditional smooth gaskets. The sizes 03-04-05 permit the rotation of your feet without disassembling them; furthermore the versions with swinging apart covers allow the lateral flanges to end up being fitted on both sides with simple fixing screws. The worm screw includes a ZI involute profile: with this worm-wheel coupling we shall get a better performance with a temperature decrease. 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) may also be mounted with this range, obtaining a equipment ratio up to 1 1:300. For larger reductions can be done to possess two gears jointly using an appropriate kit
