Electric Slew Drive Descriptions
Our slewing drives are manufactured under high-quality control
systems and a team of experienced specialists. They are designed
and manufactured by innovative fully automatic and semi-automatic
production equipment, experienced and qualified engineers. Slewing
drives are suitable for applications that require continuous or
cyclic motion and are able to handle combined loads: CPV, PV, CSP,
satellite dishes, etc. Our products have standard connection sizes
for easy and simple connection to electric, hydraulic motors or
systems.

Electric Slew Drive Features
Gear ratio
The rotation of the horizontal worm turns a gear about an axis
perpendicular to the screw axis. This combination reduces the speed
of the driven member and also multiplies its torque; increasing it
proportionally as the speed decreases.The speed ratio of shafts
depends upon the relation of the number of threads on the worm to
the number of teeth in the worm wheel or gear.
Hourglass worm
Our slewing drives are using hourglass worm technology, in which
the worm is shaped to engage more teeth in the gear. This increased
tooth engagement results in greater strength, efficiency and
durability.
Function
Slewing drives function with standard worm technology, in which the
worm on the horizontal shaft acts as the driver for the gear, in
general, the shaft is driven by electric gear motor.
