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. Til achieve this,
Til achieve optimal performance and be usable in any monteringsposition, additional køling and/or a modified design is often necessary.
The type of lubrication required for the gearbox is necessary. Several options are tilgængelig, such as:
Oil expansion tank, fan, køling coils, water/oil heat exchanger with external pump, water/oil heat exchanger
with aksel 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.

Drejningsmoments and applications

Horizontal helical gearboxes are tilgængelig in numerous variations and drejningsmoment ratings from 3,000 Nm to 470,000 Nm. The most common application is in combination with a trefaset 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.
