本文叙述了通过齿轮系耦合的二个编码器之间的纠错方法。 从以前的知识可以了解到,编码器的容量可通过减速齿轮耦合多个码盘加以扩展。容量的增加等于所用的齿轮比。但是由于齿轮间隙和渡越点位置的不确定性,产生了需要消除的模糊度问题。在单级码盘情况下,使用松香码 This article describes the error correction method between two encoders coupled by a gear train. As can be appreciated from the previous knowledge, the capacity of the encoder can be expanded by coupling a plurality of code wheels via a reduction gear. The capacity increase equals the gear ratio used. However, due to the uncertainty of gear clearances and crossing positions, ambiguity problems that need to be eliminated arise. In the case of a single-stage code, the rosin code is used
