Pneumatic Cylinders
How Can You Accurately Measure and Eliminate Rotational Backlash to Achieve Precision Positioning in Pneumatic Actuators?
Rotational backlash mitigation requires systematic measurement using precision encoders or laser interferometry to quantify angular play (typically 0.1-2.0°), mechanical solutions including anti-backlash gearing with spring-loaded split gears, pneumatic preloading systems that maintain constant torque bias, electronic compensation through servo control with position feedback, and design optimization using direct-drive configurations that eliminate gear trains entirely.
