High Holding Torque Worm Gear Slew Drive With IP66 Enclosure For Solar Energy
High Holding Torque Worm Gear Slew Drive With IP66 Enclosure For Solar Energy
Product Description
Our enclosed housing slewing drive consists of the housing, slewing ring with external gear, hourglass worm, and other spare parts. Also we can provide electric motor or hydraulic motor to match with slewing drive , it will used for the power input source to make slewing drive to achieve clockwise and counterclockwise rotation. Our enclosed housing slewing drive can prevent the water and dust and is very suitable for used in outside. We have three types, SE, VE and SDE series slew drives, VE series are mostly applied in solar tracking system, parabolic concertrated power, while the SE series are mostly applied in construction machinery. The SDE series are dual axis slew drives, they can help the solar system to track the sun at any time and at any direaction. They has been exported to more than 40 countries, and we can also provide customized slewing drive in accordance with customers' requirements.

Application
SDE series is an enclosed housing slew drive with IP66 enclosure protection level. It is designed with an hourglass worm shaft with 5 teeth in contact between the slew ring and the worm shaft. This design offers a very solid back holding torque capacity for the heavy loads. Solar energy, CSP, CPV, satellite antenna and many more industries with high contamination of fine particle environment prefer this drive for its tightness. It is also the choice for most of outdoor installations subjected to heavy rain and snow as it is well sealed compared to other designs.
