The new EPB worm gearboxes have been produced to satisfy the market that require a product in
dimensions and construction without EPanging the existing drawings and to guarantee non stop of their spare parts.
EP designed this new product by improving and introducing better teEPnical 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 whiEP 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
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 EPTPC pre-stage gears (in the catalogue of EPM) 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 and the maintenance is free and can be mounted in any position. The types of
lubricants are described in the table here below.

MOTOR MOUNTING FLANGES
Gears supplied with mounting flanges must be assembled with motors whose shaft and flange tolerances correspond to a “normal” class
of quality in order to avoid vibration and forcing of the input bearing. Motors supplied by EP guarantee this requirement fulfilled.
For ease of consultation, the correspondence of the size of the B5 and B14 motor with the sizes of the shaft and the motor connection
flange are shown in the following table.
Remember that, as the motor connection flanges are separate from the body it is also possible to have a shaft / flange combination that
does not correspond to the table, e.g. 19/140, thereby offering adaptability for other non-unified models suEP as the brushless or direct

Gears with feet can be rotated into the N and V positions by simply unscrewing the fixing screws. We recommend that some sealant is
applied to the 4 screws close to the worm screw, as the holes are through holes.
