Helical bevel drive for bevy manufacturer
June 1st 2007 A large proportion of gearboxes in
the UK food and drink industry are
helical worm units, with average
efficiencies of about 75%.
Retro-fitting Flender helical
bevel geared motors, with
typical efficiencies of 96%,
can provide efficiency
improvements of up to 28%,
according to Siemens
Automation & Drives.
Significant energy savings
were made at a large
Midlands brewery following
the installation of Flender
Motox helical bevel geared motors.
The brewery's conveyor drive
featured non-Flender helical worm
drives, each using 1.5kW at 82rpm,
with an overall drive efficiency of
59%.Actual monitored power
consumption was 1.1kW.
When a Flender helical bevel
drive
with an energy efficient
motor was fitted, providing 1.5kW
at 82rpm, drive efficiency improved
to 81% and the actual monitored
power consumption dropped to
48kW.New helical bevel units were
fitted following this result, with
motors achieving 55kW
consumption.
Overall savings
were
calculated
assuming an
energy
charge of
6p/kWh, and
equated to £562/annum per unit.
At the brewery, 42 Flender Motox
units were installed, calculating
typical energy charged at 6p/kWh,
this equated to almost £24,000 in
savings per annum. More articles from Siemens Automation & Drives: |
