【Abstract】 In order to discuss the design and computation methods of egg’s pointed end and blunt end automatic orientation,the dynamics and motion regularity were analyzed and the mechanism of axial motion which was generated by the egg on two rolling conveyer rollers was studied. Results showed that the regularity of egg axial motion accorded with the principle of alternating axis friction wheel drive. The theoretical calculation methods of axial motion displacement and the model of transmission relation between egg and rollers were built. The test methods and practical calculation methods of axial motion parameters of egg were also established. Results showed that the regularity of actual displacement for axial motion of city chicken eggs corresponded with the calculation results in theory and the correction factor was 0. 55( diameter of 30 mm,center distance of 57 mm,convey speed of 57 mm / s). It was practicable to analyze the axial motion of eggs on the supporting rollers by using the principle of alternating axis friction wheel drive which laid the theoretical foundation of design and computation of automatic orientation device of pointed end and blunt end of eggs.更多还原
