摘 要:針對小模數(shù)齒輪傳統(tǒng)方法測量難,費(fèi)時費(fèi)力等缺點(diǎn),提出了一種基于三坐標(biāo)測量機(jī)CCD測頭在齒輪偏差測量中的新方法。該方法可以實(shí)現(xiàn)在齒廓有效工作范圍內(nèi)自動快速掃描齒廓坐標(biāo),并直接進(jìn)行數(shù)據(jù)存儲與處理,通過漸開線擬合的方法得到各偏差,實(shí)現(xiàn)在線測量。理論分析和實(shí)驗(yàn)表明,本方法對小模數(shù)齒輪的測量具有簡便、無接觸和效率高的優(yōu)點(diǎn)。[著者文摘]
Application of Pitch and Tooth Error of Involute Spur Gear by CCD Camera on CMMRen lifen Liao Shipeng Liao JunbiRen lifen Liao Shipeng Liao JunbiAbstract:Traditional method of small module gear is difficult. This paper presents a new method to measure pitch and tooth error of involute spur gear by CCD camera on CMM. The method can be achieved in the value of the profile automatically scan profde coordinates and processing data, through fitting involute to obtain the deviation. Theoretical analysis and experiments show that this method is simple, non contact and efficient for small module gear.[著者文摘]
