Gear Transmission Error Accuracy with Small Rotary Encoders

J D Smith · Proceedings of the Institution of Mechanical Engineers, Part C: Mechanical Engineering Science · 1987

Two small (90 mm) angle encoders were tested back to back to assess sizes of high-frequency components of error. The results showed errors well below 0.1 seconds of arc at the rotation multiples likely to be relevant for gear noise and vibration testing.
