Design And Analysis Of Cross-axis Universal Coupling Without Bolt Based On Finite Element Method

Cross-axis universal coupling without Bolt is a kind of desirable coupling, which possess high torque, long service life and a wide range of applications. Consequently it is used widely in the fieldof traffic and transportation, metallurgy, heavy machinery,etc,especially provides favorable conditions for the technological transformation of metallurgical industry and upgrade of mechanical products. Using this new type of mechanical fundamentals will improve operability by a large margin, so as to get higher economic benefits. It is also widely used in products just like rolling mill.ANSYS is a kind of FEM software which has good generability, strong practicality, strong function and extensive application. In its wide application domain, analysis of strength and stress distribution to parts has been applied widely and developed. This paper uses statical analysis and dynamic modal analysis function in ANSYS, based on specific load on Cross-axis universal coupling without bolt, to analyze its strength, rigidity and vibration. According to the stress status, the principal stress distribution under the static condition has been obtained by the static analysis of crossed-shaft. First, the strength of crossed-shaft and bear was calculated; especially the contact strength between crossed-shaft, fork joint and bear was analyzed. Then, by using SolidWorks software, 3D solid model of crossed-shaft universal clutch was built.At the same time, strength calculation and modal analysis based on FEM was also performed. Finally, optimal design of fork joint on non-bolt crossed-shaft universal clutch was achieved and the optimization result was also analyzed.
