we’ve a gearbox with a motor mounting flange that’s separable from the housing which incorporate the oil seal; in this manner we avoid any threat of damaging the oil seal in the event of replacement of the insight flange and the O-Ring could be eliminated. All the aside covers, swinging and with foot, have O-Rings instead of traditional toned gaskets. The sizes 03-04-05 allow the rotation of the feet without disassembling them; furthermore the variations with swinging aside covers permit the lateral flanges to become fitted on both sides with basic repairing screws. The worm screw has a ZI involute profile: with this worm-wheel coupling we will get a better overall performance with a temperature decrease. The gearboxes and motors are painted with RAL 9022 aluminium colour 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 present in the catalogue of CHM) may also be installed with this range, finding a equipment ratio up to 1 1:300. For CH WORM GEARED MOTORS AND WORM GEAR UNITS bigger reductions is possible to have two gears with each other using a proper kit
