High Torque Single Axis Slewing Drive With Electric Motor For Sun
Tracking System
Single Axis Slewing Drive Description
SE enclosed slewing drives are now the most popular type in the
market which can help power movement in machinery such as wind
turbines, military equipment, digger s and also in clean energy
such as solar trackers, concertrated solar power stations, In
addtion, could be also apply in other areas such as medical
equipment, forestry, waste management and industrial positioners.
The housing fully encapsulates all the drive components such as the
double enveloping worm gearset, planetary gearing, and turntable
bearing so that they have total protection from the elements. The
enclosed drive is also advantageous if you’re mounting inside so as
not to see the parts in motionto avoid injuring to site workers.
SE slewing drives are ideal for jobs that require both load-holding
and rotational torque from the same gearbox. The fully-enclosed
comes with Hangtuo's patented hourglass worm technology, or cone
drives and double enveloping worm gearsets where required, for
maximum load-holding and efficiency. Each size is rigorously tested
for reliable performance The types range from 1 inch to 25 inches
which producing 1.8kNm to 89kNm of holding torque, 0.3Nm to 21kNm
of output torque, 1 kNm to 346 kNm of overturning moment load
capacity, and gearbox reduction ratios of 31:1 up to 150:1.

Installation
Vertical installation
It is advised to mount the slewing drives referring to the drawing
upside in solar applications for better protection.
For other applications, the mounting directions shall be based on
the evaluation of the protection level and it shall be better for
better protection.
Horizontal installation
It is advised to mount the slewing drives upside down on the
azimuth axis in solar applications for better protection and add
protection for the elevation axis.
For other applications, the mounting directions shall be based on
the evaluation of the protection level and it shall be better for
better protection.
