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]
