Small Diameter Slew Ring Drive With High Precision Helical Worm Gear For Small Solar Trackers
Introduction
A slewing bearing ring is a rotational rolling-element bearing or plain bearing 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 windmill.
The helical gear and hourglass worm make it achieve multi tooth contact, which made it can bear the axial force, radial force and the tilting moment at the same time.
