Dual Axis Worm Gear Slewing Drive With Enclosed House And Small Backlash For PV Tracker
Description
A slewing drive or slewing bearing is a rotation part that typically supports a heavy but slow-turning load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis solar tracking system. The slewing drive is made up of an envelop worm, gear, house etc. 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
