Worm Gear Dual Axis Slew Drive For Solar Tracker With Multi Tooth Contact And 24V Motor
Dual Axis Slew Drive Description
The most common slewing drive application for the dual-axis slewing drives are dual-axis solar trackers, such as heliostats and concentrated photovoltaics (CPV), and satellite or radar dishes. Other applications include automotive lifts, robotic arm positioners, and stage equipment.
Solar Tracker dual axis slew drive is perfect solution in the dual axis solar tracking applications.
Dual axis slew drive have three types solutions with slew drives:
In general, for easy bracket structure, the sde slew drive would be the perfect solution, but the other two are also very popular.
Two SE slew drives
One SE slew drive and one VE slew drive
