Double Enveloping Worm Gear Slew Drive With Geared Motor For Solar Panel Tracking System
Worm Gear Slew Drive Description
Vertical double enveloping worm gear slew drive with planetary gearbox's applications mainly for solar panel tracking system, especially in horizontal single axis solar tracking system. It is also widely used in CSP, such us fresnel, heat tower, parabolic etc.
Horizontal double enveloping worm gear slew drive, like its name, is installed horizontally, it is mainly applied in winch crane, slewingdeck crane, crane winch design, excavator swing drive. Our unique small backlash slewing drive can also be used in high precision fields such us antenna, satellite, slewing table, dishes......
The planetary gear reduction gearbox working principle makes itself for solar tracker bear a big radial load due to the proportionate distribution of torque. What's more, our slewing drives has hydraulic motor configurations. We have all series slew gearbox size meet customers' different demand.
Features
1. Rotate ±60°, hard stop inside to ensure system safety
2. Connect a driving motor from the left, right side or in the middle
3. The clearance is already set by the producer before factory, so no need to adjust it when installation
4. Grease had been filled before factory, just need refill each 5 years
4. Simple installation and low maintenance
5. Compact design and space saving
6. The gear is self-locking, so no need of addtional brake
7. Easy and fluent method of starting and stopping
8. High tilting torque and backholding torque to improve safety under harsh environment
