1 000 mm多参量集成大齿轮样板设计
1000 mm multi-parameter integrated large gear artifact design
摘要
Abstract
Large gear artifacts are physical standards for calibrating large gear measuring instruments.On-ly a few foreign metrology institutes have made breakthroughs in this field.To solve development difficul-ties,this paper studied design methods for large gear artifacts.It discussed dimensions,structures,geo-metric features,and core parameters in detail.We innovatively designed a new multi-parameter standard artifact with a 1 000 mm outer diameter.The artifact used a symmetrical structure of internal and external gear rings.It integrated multi-angle helices,involute profiles,and pitches into one carrier.Finite element analysis evaluated gravity deformation under different length-to-diameter ratios.These simulation results verified the rationality of the design.Thermodynamic analysis provided theoretical data for subsequent physical measurements.This 1 000 mm artifact offered efficient and high-precision multi-parameter com-prehensive calibration.It had great value for improving China's gear quality control.It also enhanced met-rological traceability for high-end heavy equipment.关键词
