Horizontal Mounted Small Worm Drive Gearbox For Solar Tracking
Slewing Gearbox Description
A slewing gearbox, also known as a slewing drive or slew, is a
mechanical device used to rotate or slew heavy loads in various
applications. It is commonly employed in machinery such as cranes,
excavators, wind turbines, and solar tracking systems.
The main purpose of a slewing gearbox is to provide controlled
rotation and support for the load. It consists of several key
components, including:
Housing: The outer structure that houses the internal components of
the gearbox.
Slew Ring: A large, circular bearing that allows the gearbox to
rotate smoothly. It provides support and stability to the load
during rotation.
Gear Train: The gear train consists of a set of gears arranged in a
specific configuration to achieve the desired rotational output. It
typically includes a combination of spur gears, helical gears, or
worm gears.
Motor: The motor provides the driving force to rotate the slewing
gearbox. It can be an electric motor, hydraulic motor, or even a
manual crank, depending on the specific application.
Output Shaft: The output shaft is connected to the gear train and
extends from the gearbox housing. It transfers the rotational
motion to the load, enabling it to rotate.
