Hydropower
Specialised gear units for
hydropower applications
Santasalo has been manufacturing gears for the hydropower industry for over 20 years
with an installed base in Scandinavia, Central Europe and North America. Santasalo’s
product portfolio includes a special gear series for hydropower in the power range of
200-6000 kW. With its specialised design, the hydropower gear series is suitable for all
types of turbines independent of the shaft direction.
The Santasalo gear units are equipped with axial
bearings designed to withstand the axial force from
the turbine. The gear units are pressure lubricated
and the gear housing is designed to eliminate the
requirement for an external oil tank.
The new special gear series is designed for the
power range of small hydro power stations. The
power range is from 200-6000 kW and the speed is
80-350 rpm. The generator speed is 600-1200 rpm
and can be used both in 50 Hz and 60 Hz.
Project based design, in-depth knowhow and modern manufacturing
methods enable us to customise
gear solutions to meet the stringent
requirements of small hydro power
plants with precision
Designed to your Specification
Santasalo’s gear units for hydropower applications
are designed for both horizontal and vertical
turbines. The gear units are connected to the
foundation with the flange in the upper part of the
gear unit where the axial bearing is also placed.
This stops the axial force from the turbine acting
on other parts of the housing. The gear housing
is designed to exclude the need for an external oil
tank and is equipped with large inspection covers
for efficient service and inspection of the gear unit.
The turbine shaft is connected to the gear unit
with flange connection, OK coupling or shrink disc.
Between the generator and the gear unit, flexible
disc or tooth couplings are used. The low speed
shaft has a hole inside for the adjustment device
of the turbines impeller. The gear housing has a
flange for attachment of adjustment device.
The gear series has been designed with leading
turbine manufacturers for easy installation and
maintenance.
The gear units are one stage with increasing
ratio and helical teeth. The bearings can absorb
the axial force of the turbine so there is no need
for a separate bearing for the turbine. The force
towards the gear is going through the gear housing
to the foundation.
