we’ve a gearbox with a motor mounting flange that is CH WORM GEARED MOTORS AND WORM GEAR UNITS separable from the housing which incorporate the essential oil seal; in this manner we avoid any threat of damaging the essential oil seal in the event of substitute of the insight flange and the O-Ring can be eliminated. All the aside covers, swinging and with foot, have O-Rings rather than traditional toned gaskets. The sizes 03-04-05 allow the rotation of your toes without disassembling them; furthermore the versions with swinging apart covers allow the lateral flanges to become installed on both sides with simple fixing 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 safeguard 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 installed with this range, obtaining a equipment ratio up to at least one 1:300. For larger reductions is possible to possess two gears collectively using an appropriate kit
