IP66 SE12 Slew Drive Gearbox With High Accuracy And Low Speed For
Solar Panel Trackers
IP66 Self Locking Slewing Drive
Slewing drive (slewing reducer) is what we often call the
combination of slewing bearing and worm. It is a new type of
product, usually composed of worm, slewing bearing, housing, motor
and other parts. Since the core component adopts slewing bearing,
it can bear axial force, radial force and overturning moment at the
same time. Compared with traditional rotary products, rotary drive
(rotary reducer) has the characteristics of simple installation,
easy maintenance, and saving installation space to a greater
extent. This product can be widely used in construction machinery
and new energy fields such as heavy-duty flatbed trucks, container
cranes, truck-mounted cranes, aerial work vehicles, and solar power
generation systems for sun patrols.
Advantages
The slewing bearing manufacturer explained that it has the
following obvious advantages:
The slewing drive can bear axial force, radial force and tipping
moment at the same time because the core component adopts slewing
bearing. The rotary drive pair is easy to install, easy to
maintain, and saves installation space to a greater extent.
Structurally, the meshing tooth surfaces of the rotary drive are in
line contact, which greatly improves the bearing capacity. The
transmission is smooth and the noise is small.
In practical applications, the high integration of the rotary drive
device makes it unnecessary for the user to purchase and process
each component of the rotary device one by one, and to a certain
extent, it also reduces the preparation process at the beginning of
product production, thereby greatly improving labor productivity.
The worm gear and worm drive have the characteristics of reverse
self-locking, which can realize reverse self-locking, that is, only
the worm gear can be driven by the worm, but the worm cannot be
driven by the worm gear. Such as the self-locking worm mechanism
used in its heavy machinery, its reverse self-locking can play a
role in safety protection. This feature makes the slewing drive
device widely used in lifting, aerial work and other equipment.
While improving the technological content of the main engine, it
also greatly improves the operation stability and safety factor of
the main engine. It is an important embodiment of the safe
construction application of mechanical equipment.
