摘要:
An anti-backlash system comprising a single drive pinion and motor is disclosed. In an exemplary embodiment, the single drive pinion is situated between two idler gears and is allowed to move in the radial direction relative to the bull gear. A preload force provides for the substantial absence of backlash at low torque loads. The pinion moves to the center point between the two idler gears and balances the torque during high torque loads. The present anti-backlash system is well suited for use in drive and positioning systems that are subject to variable and reversing loads, such as those experienced by radio telescopes in variable wind conditions.
