Siemens supplies sweet solution
July 1st 2010 When a worm gear drive crown
wheel failed due to overload on a
crucial conveyor belt at British
Sugar's Wissington plant in King's
Lynn, the priority was to get things
running again quickly – and the
ultimate result was a minimum of
10% improved efficiency.
The Siemens service team
suggested a more energy-efficient
bevel helical Flender FZG gearbox,
size B3HH08.Where the existing 280
Cavex worm gear unit had a rating
of 12,500Nm at 1000rpm, the new
Flender bevel helical unit was rated
at 27,000Nm, a considerably higher
torque rating. The bevel helical unit
also had the same hollow shaft
diameter as the Cavex worm gear
unit, so the customer could use the
existing headshaft.The old unit was
between 74% and 85% efficient; the
new one offered 95% efficiency, an
improvement of at least 10%. More articles from Siemens Industry Automation & Drive Technologies (Flender): |
