Vertical Single Axis Solar Slewing Drive Gearbox For Flat Auto PV Trackers
Vertical Single Axis Slewing Drive Description
Slewing drives use worm gear technology, where a worm on a horizontal shaft acts as a drive for gears. The rotation of the horizontal screw rotates the gear about an axis perpendicular to the axis of the screw. This combination reduces the speed of the driven component and also increases its torque. As the speed decreases, it increases by the reduction ratio. The reduction ratio depends on the relationship between the number of threads on the worm and the number of teeth in the worm wheel or gear.
As technology advances, more rotary drives are using spherical enveloping worm technology, where the worm is shaped to mesh with more teeth in the gear. This increased tooth engagement allows for greater strength, efficiency and durability of the slewing drive.
