we’ve a gearbox with a motor mounting flange that is 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 alternative of the insight flange and the O-Ring can be eliminated. All the aside covers, swinging and with ft, have O-Rings instead of traditional smooth gaskets. The sizes 03-04-05 allow the rotation of your toes without disassembling them; furthermore the variations with swinging apart covers permit the lateral flanges to be installed on both sides with simple repairing screws. The worm screw includes a ZI involute profile: with this worm-wheel coupling we will get a better functionality with a temperature decrease. The CH WORM GEARED MOTORS AND WORM GEAR UNITS 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) can also be mounted with this range, finding a gear ratio up to 1 1:300. For larger reductions is possible to possess two gears with each other using an appropriate kit
