Projection Method Measurement on Non-rigidity Gear Pitch CumuIative Errors
摘要
Abstract
TO resOIve the prObIem Of micrO gear Or nOn-rigidity gear pOsitiOn aIteratiOn errOrs,a nOn-cOntact prOjectiOn measurement methOd is adOpted. AppIing prOjectiOn measurement appIiance and rOtary tabIe by singIe pitch methOd and span pitch add-On spOt methOd,thrOugh cOmpensatiOn Of divisiOn errOrs Of rOtary tabIe,gear pitch cumuIative errOrs measurement is finished which is prOved reasOnabIe by absOIute methOd measurement. ThrOugh anaIysis Of the instaII gear eccentric errOrs,instrument measuring errOrs and aiming aIignment errOrs,the gear pitch cumuIative errOrs uncertainty is gOt abOut ± 65μm by singIe pitch methOd and ± 64μm by span pitch add-On spOt methOd which aII meet the demand Of measurement precisiOn. FinaIIy,a cOncIusiOn is made that the tested nOn-rigidity pIastic gear precisiOn IeveI is cOnfirmed as 10 IeveI by bOth measuring methOds. By cOmparisOn,span pitch add-On spOt methOd has mOre advantage in Iess measuring times and easy cOntrOI in gear pitch cumuIative errOrs measurement.关键词
