0.1° Accuracy Slewing Drive For Precise High Output Torque PV
Tracking Applications
Product Description
A slewing drive, also known as a slew drive or slew bearing drive,
is a mechanical component used in various applications to enable
the controlled rotation of a load around a central axis. These
devices are commonly found in industrial machinery, solar tracking
systems, wind turbines, construction equipment, and other
applications where controlled and precise rotation is required.
Key features and components of a slewing drive include:
Main Housing: The slewing drive typically consists of a sturdy,
compact housing that contains all the internal components. The
housing is designed to withstand heavy loads and environmental
conditions.
Central Axis: At the core of the slewing drive is a central axis,
often referred to as the worm gear, which serves as the pivot point
for the rotational movement.
Gear Mechanism: The primary function of the slewing drive is to
convert rotary motion into angular motion. This is achieved through
a gear mechanism, typically consisting of a worm screw and a ring
gear.
Drive Motor: To control the rotation of the slewing drive, an
external drive motor is usually attached. The motor provides the
necessary torque and power to rotate the load.
Bearings: High-quality bearings are crucial components of a slewing
drive. They provide support and reduce friction, enabling smooth
and efficient rotation. Some slewing drives feature multiple rows
of bearings for enhanced stability.
Seals and Lubrication: To protect the internal components from
dust, dirt, and moisture, slewing drives are equipped with seals
and gaskets. Proper lubrication is essential to reduce wear and
ensure long-term reliability.
Mounting Flange: Depending on the application, a mounting flange
may be included to attach the slewing drive securely to the
surrounding structure.
Output Gear: Some slewing drives have an output gear, which is
connected to the load that needs to be rotated. This gear can be
customized to suit the specific requirements of the application.
Slewing drives are designed to handle heavy loads and offer precise
control over rotation, making them ideal for various applications
that require controlled motion. Their versatility, durability, and
ability to support both axial and radial loads make them valuable
components in industries such as construction, renewable energy,
and manufacturing.
