High Transmission Efficiency SDE7 Gear Slew Drive Gearbox, Dual Axis And Self Lock For Solar Trackers
Introduction
Dual axis slewing drives are perfect for situations which need rotate both vertically and horizontally. Typical applications include dual axis solar trackers, satellite and radar dishes, machines which need moving 360 degrees at both directions.
Changzhou Hangtuo Mechanical Co.,ltd is a professional manufacturer and exporter of slewing bearing/slewing ring/slew circle,slewing drives/slew drive, which are mainly applied in port machinery, mining machinery, welding machinery, construction vehicles, modular vehicles, single or dual axis solar tracking systems, and small wind power systems, satellite, antenna etc.
Features
1. High backholding torque to improve the solar tracking system's safety
2. Enveloping worm drive inside
3. Multi tooth contact to ensure high load
4. Self-locking function

Glossary of Key Parameters
Tilting Moment Torque: Torque is the load multiplied by distance between the position of load and the center of slewing bearing. If the qorque generated by load and distance is greater than the rated tilting moment torque, slewing drive will be overturned.
Radial load: Load vertical to the axis of slewing bearing
Axial load: Load parallel to the axis of slewing bearing
Holding torque:It is the reverse torque.When the drive is rotating reversely, and parts are not damaged,The maximum torque achieved is called holding torque.
Self-locking: Only when loaded, the slewing drive is not able to reverse rotate and thus called self-locking.
Customized Services
1. Special design based on different applications and projects
2. Different types of motors could be matched, such as hydraulic motors, stepper motors, electrical motors etc.
3. Different colors are available based on RAL code; our standard color is RAL 9006.
