Tracking Sun Slew Drive Bearing With IP66 Painting For Concentrated
Heliostat
Double Enveloping Slew Drive
Circumferential slewing drive is a traditional and mature
technology, but slewing drive is relatively new as an integrated
structure. The improvement of integration degree not only brings
many advantages in application, but also creates a lot of
convenience for manufacture and use. Improving the precision and
durability of this structure and further expanding its field of use
are important tasks for design, manufacture and users to
continuously explore improvement and development in practice.
The specifications and models of the slewing drive pair are
different, such as SE/ZE/VE//ZSVE/ZSDE, etc.1", 3”, 5”, 7”, 9”,
12”, 14”, 17”, 21”, 25” and other specifications. The “SE” in the
model label stands for: the English abbreviation of Slewing and
Enclose Q370571775.
Because the core component adopts slewing bearing, it can bear
axial force, radial force and tilting moment at the same time. The
slewing drive pair is easy to install, easy to maintain, and saves
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, solar power generator systems for sun
patrols, etc.
Slewing drives can be basically divided into single worm drive
slewing drives and double worm drive slewing drives.

Fields of Application for Slewing Drives
Worm gear and worm mechanism are often used in occasions where two
shafts are staggered, the transmission ratio is large, the
transmission power is not large, or intermittent work.
The slewing drive can be applied to the main engine that does
circular motion, such as crane turntable, rotating machinery, and
other machines that perform circular work. Once the product is put
into production, it can be widely used in the field of construction
machinery represented by aerial work vehicles and truck cranes, as
well as in the field of new energy represented by solar
photovoltaic power generation and wind power generation, as well as
other fields of automation, machine tool manufacturing, aerospace
communications, etc. It can be said that, The market potential of
this product is huge.
