VE7 Double Enveloping Small Slewing Drives For Horizontal Single Axis Solar Trackers
Industrial Use Worm And Gear Slew Drive Description
Slewing drive is of high reliability, it is designed and
tested to guarantee a 30-year field life. So all of the raw
materials must meet the standards required by the solar tracking
system. We implement a sound quality control to ensure out products
of high quality, reliable and low cost at the same time.
Slewing drives is of high performance. It is powered with hourglass worm technology to give the gearbox enormous strength and power, maximize survivability load-holding as well as increased efficiency and accuracy.

Q&A
How to choose the right swing drives?
In the selection and calculation of the slewing drive, we should
consider that the slewing bearing generally bears the combined
action of the axial force Fa, the radial force Fr and the
overturning moment M during the use process. For different
applications, due to the working mode of the main engine And
different structural forms, the combination of the above three
loads will change, sometimes it may be the joint action of the two
loads, and sometimes it may only be the sole action of one load.
There are two types of installation methods for slewing bearings:
seat type installation and suspension type installation.
According to the information provided by the product samples, the
static bearing capacity curve can be used to preliminarily select
the slewing bearing according to the selection and calculation
method of the slewing bearing, and then confirm with the technical
department of our company. We can also provide our company with
relevant information on the application of slewing bearings, and
our company will design and select them.
