High-Precision Planetary Gearboxes for Robotics & Automation
Anand Gears planetary gearboxes deliver exceptional torque density in an exceptionally compact package. The innovative planetary mechanism — where small planet gears orbit around a central sun gear inside a rotating ring gear — distributes loads across multiple simultaneous gear meshes, enabling high reduction ratios in minimal space. Available in 1-stage, 2-stage, and 3-stage configurations with ratios from 3:1 to 512:1, our planetary gearboxes achieve backlash <3 arcminutes through precision manufacturing and tight tolerances. This makes them the standard choice for robotics, machine tools, precision positioning systems, and automation equipment where accuracy and repeatability are non-negotiable.

Understanding Backlash in Planetary Gearboxes
Backlash is the slight play or angular lost motion when the direction of rotation reverses. In an ideal zero-backlash gearbox, the instant the motor reverses direction, the output shaft immediately reverses too. In reality, manufacturing tolerances cause a tiny delay — typically measured in arcminutes (1° = 60 arcminutes). Anand Gears planetary gearboxes achieve <3 arcminutes backlash through precision manufacturing, tight gear tolerances, and advanced assembly techniques.
Why This Matters: In robotics, even 5-10 arcminutes of backlash causes perceptible joint "slop" and reduces end-effector positioning accuracy. In machine tools, backlash introduces runout and surface finish degradation. In automation, backlash creates synchronization errors in multi-axis systems. Our <3 arcminute specification ensures crisp, predictable motion.
