High Efficiency Worm Gear Slew Drives With Self-Locking Feature For
Solar Renewable Energy
Corrosion Resistance Slew Drive Description
Worm gear self locking slewing drives are typically constructed
with materials that offer corrosion resistance, making them
suitable for outdoor applications. The housing is designed to
protect internal components from environmental factors, ensuring
longevity and durability. This durability is crucial for the
reliable operation of solar tracking systems in various weather
conditions.
A worm gear solar tracking slewing drive combines the precision of
worm gear mechanisms with the advantages of dual-axis tracking,
compact design, durability, and maintenance-free operation. These
features make it a key component in solar tracking systems,
contributing to increased energy efficiency and sustainability in
solar power generation.

Features:
Dual-Axis Rotation:
Slewing drives allow for dual-axis rotation, enabling movement in
both horizontal and vertical directions simultaneously.
High Torque Density:
These gearboxes are designed to provide high torque output in a
compact and lightweight form, making them suitable for applications
where space is limited.
Self-Locking Mechanism:
Slewing drives often have a self-locking mechanism that prevents
the load from back-driving the gearbox, ensuring stability and
safety in stationary positions.
Applications
Solar Tracking Systems:
Slewing drives are widely used in solar tracking systems to rotate
solar panels, ensuring optimal exposure to sunlight throughout the
day.
Wind Turbine Pitch and Yaw Systems:
They are employed in wind turbines to control the pitch and yaw
mechanisms, enabling the adjustment of blade angles and the
orientation of the entire turbine.
