Abstract:
To eliminate dynamic disturbances to the Space Station and its on-board experiments,
it would be desirable to provide actuator drives and drives for dynamic experiments
which have a zero net output torque. This can be accomplished by utilizing drives
with dual, counter-rotating, torque-balanced outputs. The innovation is a planetary
traction drive with dual, roller clusters each feeding an output. The two outputs
are at equal speed and torque and opposite rotation. A specific drive ratio, torque
requirement, and speed will be studied in Phase I. Drive kinematics, size, life,
and expected performance will be defined. A final design and manufacturing drawings
will be completed. A test program for Phase II will be delineated.
Potential Commercial Application:
Potential Commercial Applications: Uses could be for torque-balanced drives for
scientific instruments and dual drives for propulsion systems.
