Industrial helical gearboxes up to 470,000 Nm

SEVA-tec H series gearboxes are used in industrial applications where high stress is involved.
is required. The H series is manufactured for maximum performance in the smallest possible space. To achieve this,
To achieve optimal performance and be usable in any installation position, additional cooling and/or a modified design is often necessary.
The type of lubrication required for the gearbox is necessary. Several options are 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. We would like to point out that in each
A reinforced extruder variant of the common size can also be obtained from SEVA-tec.

Torques and applications

Horizontal helical gearboxes are available in numerous variations and torque ratings from 3,000 Nm to 470,000 Nm. The most common application is in combination with a three-phase motor. This is mounted directly to the gearbox via an IEC B5 flange. For larger gearboxes with integrated motors, we can supply them pre-assembled on a base frame, including the motor coupling.
