High-Resolution Rotary-To-Linear Motion Converter
Abstract
Compact rotary-to-linear motion converter combines high load-carrying ability with finely resolvable movement. Simple and inexpensive to manufacture. Helical coil of metal ribbon wrapped around spool. Bearing supports spool on fixed base. Restraining bar prevents collar from rotating, but allows it to rise and fall. 1,000-turn coil of ribbon 0.010 in. thick provides for translation of collar over distance of 10 inches. Coil made from flattened roll-formed wire. Material inexpensive, strong, and resistant to fatigue.
