Zero backlash gearless rotary actuator usable with solar panels
11175071 · 2021-11-16 · ·

A rotary actuator has a rotatable platform rotatably supported on a base. The rotatable platform has a friction surface. An actuator band is operated by a band clamp so as to be selectively frictionally engageable with the friction surface. A motion actuator is coupled between the base and the actuator band such that change in length of the motion actuator causes corresponding movement of the actuator band. A brake band is operated by a brake band actuator so as to be selectively frictionally engageable with the friction surface, the brake band anchored to the base.
