Spur gear mapping, the use of both methods is best to use each other Luoyang checking spur gear pinion, so a more accurate determination of the modulus or diametral pitch, this time surveying and mapping work completed. Special Note: The above mapping method in case we can prejudge or investigation of a standard system of gears were used, and if gear "Everything is unknown," the above method can only reference, and through other means comprehensive determination. Some believe that the above mapping methods just to work soon or initial mapping conducted spur gear counterparts have some help. Theoretical spur gear precision forging Research UK Institute of Science and Technology of the University of Manchester Chitkara NR et al spur gear plastic molding simulation analysis made Luoyang spur gear spur gear, with the upper limit of energy analysis method and upsetting spur gears The deformation law; Dohamann F et al stress analysis and principal activities of the cold forging metal gear and mold stress situation when given along the tooth surface profile of the normal stress distribution of numerical approximation. Korean scholars JHSong and YTIm developed a spur gear cold forward extrusion auxiliary system that can be shaped according to the input gear tooling parameters given for practical gear. Kondo K and Ohga K gear proposed diversion casting Choi JC development shunt proposed spur gear forging process inwardly shaped shunt, and two-dimensional finite element analysis decompression. Jongung Choi and Hae-Yong Cho, who proposed a new dynamic linear velocity field can spur gear casting and studied deeply into its forming process using upper bound method spur gears, the main force has been formed and gear conclusions about the use of Yang DY Gang, visco-plastic finite element method Spur Gear Precision Forging of numerical simulation. KnoerrM DEFORM simulation in 1992 with a three-station circular ring gear blank forging process, and speculations that may occur during the forming folding defects and improve shaping parameters based on the simulation result, a non-defective parts. Germany Th.Herlan finite element analysis using ANSYS software to optimize the geometry of Luoyang standard gear spur gear teeth, thereby reducing the pressure and the casting mold stress given by FEM analysis seeks to mold and shape optimization gear, final The precision forging gear fatigue tests with traditional technology, the gears were compared.
