VE8 Vertical Solar Tracker Drive With Helical Gear And Envelope
Worm For Flat Single Tracking System
Slewing ring, also known as slewing bearings or turntable bearing,
is a large bearing which is able to sustain the more axial load,
radial load and tilting moment. It is the essential machinery
transmission parts. It has the inner and outer ring, rolling and
One can consider the slewing drive as a gearbox because the core
motion components are the slewing bearing and worm shaft. It also
consists of auxiliary components such as seals, housing, and motor.
As a power source, slew drive motor is usually DC planetary gear
motor, DC stepper motor, AC gear motor etc. AC hydraulic motor is
mainly used in the construction machinery as a power drive system.
As the core component is slewing ring drive, slewing drive can
readily withstand the axial and radial forces.
The slew drives working principle:
The worm is driven by the motor, which drives the outer ring of the
slewing ring to rotate; the outer ring output the torque through
the flange and the inner ring of the slewing ring is fixed in the
Slewing drive has reverse self-locking because of worm gear drive
with reverse self-locking characteristics. This feature greatly
enhances the stability of the host operating and safety factor.
Compared to the traditional swing products, slewing drive gearbox
is easy to install, easy to maintain, and saves considerable
