Current status and trends in precision reducer lost motion measurement
Lost motion is the key index for describing the performance of precision reducers. Although its definition appears simple
it involves complex measurement and evaluation problems. In this paper
the principle and method of precision reducer lost motion measurement were discussed from the aspects of static and dynamic measurements. The similarities and differences of different measurement methods
and their respective advantages and disadvantages were analyzed. In addition
the commonly used evaluation methods in the industrial field were studied
and it is emphasized that the differences in the evaluation methods are primarily responsible for the differences in the obtained results. Finally
it is noted that the establishment of a dynamic measurement system for the comprehensive performance of precision reducers is imperative for meeting the industrial demand. At the same time
it is also important to establish a complete set of specifications and evaluation criteria for precision reducer lost motion measurement.
