we’ve a gearbox with a motor mounting flange that is separable from the housing which incorporate the oil seal; in this manner we avoid any risk of damaging the oil seal in the event of substitute of the insight flange and the O-Ring can be eliminated. All the apart covers, swinging and with ft, have O-Rings CH WORM GEARED MOTORS AND WORM GEAR UNITS rather than traditional flat CH WORM GEARED MOTORS AND WORM GEAR UNITS gaskets. The sizes 03-04-05 permit the rotation of your toes without disassembling them; furthermore the variations with swinging apart covers permit the lateral flanges to end up being fitted on both sides with basic fixing screws. The worm screw has a ZI involute profile: with this worm-wheel coupling we shall get a better functionality with a temperature reduction. 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 during the pressure of die-castings. The CHPC pre-stage gears (already present in the catalogue of CHM) can also be installed with this range, finding a gear ratio up to 1 1:300. For larger reductions can be done to possess two gears jointly using a proper kit
