While　cycloid　pin-wheel　precision　reducers　(referred　to　as　RV　reducers)　are　widely　used　in　industrial　robots,　a　widely　accepted　design　standard　or　verification　method　of　their　test　platforms　is　not　available.　In　this　study,　a　comprehensive　sliding-separation　test　platform　of　RV　reducers　was　developed.　The　test　platform　can　test　various　measurement　items　such　as　transmission　error,　static　measurement　of　lost　motion,　dynamic　measurement　of　lost　motion,　torsional　rigidity,　no-load　running　torque,　starting　torque,　backdriving　torque,　and　transmission　efficiency　of　the　RV　reducer　for　robots.　The　principle　and　method　of　dynamic　measurement　of　lost　motion　tests　based　on　the　two-way　transmission　error　method　were　studied　and　this　test　function　was　successfully　integrated　with　the　comprehensive　test　platform　in　order　to　increase　the　test　items　of　the　dynamic　performance　parameters　of　RV　reducers.　The　measurement　results　of　the　no-load　running　torque　of　the　RV　reducer　were　consistent　with　the　Stribeck　curve.　Based　on　the　concept　of　optimal　measurement　speed,　a　decomposition　test　method　of　the　geometric　component　of　the　dynamic　measurement　of　lost　motion　and　the　elastic　component　of　the　dynamic　measurement　of　lost　motion　was　proposed　in　the　dynamic　measurement　test　of　lost　motion.　Through　precision　calibration,　function　test　and　repeatability　test,　the　results　were　compared　with　the　data　of　enterprise＇s　samples.　The　consistent　results　have　proved　that　the　test　platform　met　engineering　requirements　and　measurement　accuracy　requirements.　Based　on　the　new　test　principle,　the　developed　platform　can　test　more　parameters　of　RV　reducers　with　high　precision　and　display　the　comprehensive　test　performance.
