Horizontal helical gear units up to 470,000Nm
The SEVA-tec gearboxes of the H series are used in industrial applications with high loads
is required. The H series is manufactured for the highest possible performance in the smallest
possible space. To this too and in order to be able to be used in any installation position,
additional cooling or a modified type of lubrication of the gear unit is often necessary. There
are several options available, such as: Oil expansion tank, fan, cooling coils,
water / oil heat exchanger with external pump, water / oil heat exchanger
with shaft end pump and air / oil heat exchanger.
At this point we would like to point out that in each standard size, a reinforced version of
the extruder can also be obtained from SEVA-tec.

Torques and applications
Horizontal spur gearboxes are available in many variants and in torque sizes from
3,000Nm to 470,000Nm. The most common application is in combination with a
three-phase motor. This is mounted directly to the gearbox via an IEC - B5 - flange.
directly to the gearbox. For larger "gearbox with motor" designs, we offer the possibility
of pre-assembling this combination, including the motor coupling.
