Vertical Single Axis Solar Tracker Slew Drive , Small Slew Drive Double Envelope Worm
Solar Tracker Slew Drive Description
The Slewing Drive can be used for any occasion where the need for full-cycle rotation and variable speed requirements. When the need for larger torque power transmission, the higher accuracy of the motion transmission or the compact structure of the body requires a higher mechanism selection, the rotary drive is the best solution. Enclosed dual axis slewing drive can realize the movement in two different directions, vertically and horizontally. Usually apply to the dual axis solar tracking systems or some machinery equipment with similar working condition.
Vertical Type worm gear Small Slewing Drive
VE worm gear means vertical installation slewing drive; mainly apply to the high working condition requirement for dust proof, rain-proof and anti-corrosion occasion. Protection grade IP66, precise 0.1°.
It has the advantage of saving equipment space, maximum load capacity, compact design, and extensive service life and reduced maintenance costs.
