61/1 Ratio Vertical Worm Gear Slewing Bearing With Enclosed House For Solar Trackers
Worm Gear Slew Drive
The slewing drive has a radial gear driven by the worm. The teeth of the gear meet with the grooves in the worm and, as the worm turns, the gear also turns. Common features for different slewing drives can include an hourglass-shaped worm, which is often considered more efficient because multiple tooth on the gear can be engaged at once. Other features can include a protective enclosure meant to keep the mechanisms clean, our slewing drives is IP66. The motor or driving component, like the spinning of a wind turbine, also might change the specific design of a slewing drive.
In general, the purpose of different slewing drives are to change axial movement to radial movement. Depending on the number of threads on the worm and the number of teeth on the gear, the speed and power of the axial force will be converted to a specific radical force. Depending on the application, a slewing drive might be useful for amplifying the torque that rotates a mechanism.
