REDUCTION APPARATUS ATTACHED ROTATION DETECTOR

摘要

PURPOSE: A reduction apparatus attached to a rotation detector is provided to detect the rotation of an output shaft of the reduction apparatus with low costs by using a general rotation detector. CONSTITUTION: An auxiliary rotation axis(58) is arranged in parallel with an output shaft. A rotation transmitter(60) transfers the rotation of the output shaft to the auxiliary rotation axis. A rotation detector(62) detects the rotation of the auxiliary rotation axis. The rotation transmitter is comprised of a first pulley, a second pulley, and a belt. The first pulley(64) is installed in the output shaft. The second pulley(66) is installed in the auxiliary rotation axis. The belt(68) interlinks the first pulley and the second pulley.
