Worm And Worm Wheel SDE7 Dual Axis Slew Drive With 24 VDC Planetary Gear Motor
Slew drive for dual axis solar tracker
The solar trackers can be divided into single-axis trackers and
dual-axis trackers by taking into account the mechanical
characteristics. Since dual-axis systems are able to obtain an
optimal tracking of the sun, they are more popular in all the types
of concentrated solar technologies, with the exception of the
trough-style system.
We have hydraulic motors and electric motors for the slew drives according to its different working conditions, details data as below:

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.
