2.1. Pedestal Assembly (Unit 2 A1)
The design of the pedestal system for the Ranger-X5 utilizes components and elements that
allow for constant outdoor exposure and 24/7 unattended operation. Utilizing multiple O-ring
seals and weather tight compartments prevents contaminants from entering the pedestal from
the outside environment. The motor drives used in both azimuth and elevation utilize a wave
generator and circular spine, eliminating traditional gearing found in most pedestal systems.
There is no traditional bull-gear and pinion, as the motor drive itself is the rotation axis.
Since the motor drives are sealed and permanently lubricated, there is no periodic maintenance
required. Additionally, this technology also eliminates backlash and the need to adjust backlash,
and provides exceptionally high positional accuracy and repeatability. The remaining bearings
utilized (elevation idler side, and drive tube stabilizer) in the Ranger-X5 are also permanently
sealed and require no maintenance.
A sealed slip ring limits the need for periodic or preventative maintenance. The slip ring is design
is originally for high-speed operation and has a proven pedigree in military and aviation
applications. Even at the highest rotation speed of the Ranger-X5 for weather operation, the slip
ring operates at less than 25% of its rotational speed capacity.
