INTRODUCTION
The new CH worm gearboxes of Chiaravalli Group S.p.A. have been produced to satisfy
the market that require a product in dimensions and construction without changing the
existing drawings and to guarantee non stop of their spare parts.
Chiaravalli Group S.p.A. designed this new product by improving and introducing better
technical modifications to offer easier application of the groups to the different assembling
configurations so that by offering a better service in flexibility and delivery time.
Starting from these considerations, we have a gearbox with a motor mounting flange that
is separable from the housing which incorporate the oil seal; in this way we avoid any risk
of damaging the oil seal in case of replacement of the input flange and the O-Ring can be
eliminated.
All the aside covers, swinging and with feet, have O-Rings instead of traditional flat gaskets.
The sizes 03-04-05 allow the rotation of the feet without disassembling them; furthermore
the versions with swinging aside covers allow the lateral flanges to be fitted on both sides
with simple fixing screws.
The worm screw has a ZI involute profile: with this worm-wheel coupling we shall get a
better performance with a temperature reduction.
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 present in the catalogue of CHM) can also be mounted
with this range, obtaining a gear ratio up
to 1:300.
For bigger reductions is possible to have two gears together using an appropriate kit.
All of the groups are supplied with a synthetic lubricant maintenance free and can be
mounted in any position. The types of lubricants
are described in the table here below.
