Fem Analysis And Study On The Carrying Capacity Of The Main Transmission System Of Cross-Roll Straightener

Straightening of the tube is an important processing job in the tube production. The cross-roll straightener is a finishing straightening the tubes, and the main transmission system is one of key components of the cross-roll straightener. With the rapid development of the industrial technology, it is of great meaning to study the capacity of the main transmission system of the cross-roll straightener for improving its production capacity, guaranteeing the safe production and improving product quality. Theφ168cross-roll straightener was taken as the example in this dissertation, the carrying capacity of its main transmission system is studied by finite element analytical software.Firstly, some parts of main transmission system of the cross-roll straightener are assembled, simplified and constructed by using contact analysis technique. By applying the large-scale general finite element analytical software ANSYS, the entire part of the cross axle type universal shaft is analyzed.Secondly, the intensity of the main part of the cross axle type universal shaft is analyzed,the stress distribute status, the dangerous position and its reasons are all done.Finally, torque of the main transmission system of the cross-roll straightener is tested with electrometric method and calculated with theoretical formula. Then the two results are compared and analyzed with each other. The accuracy and rationality of FEA results are verified.The conclusion brings a new staightener theory analysis better method. And the detailed data is a reference to the other straighteners energetic parameters calculating, technological parameters'design.
