Abstract: Aiming at the problem of bolted joint offlange with Crosstooth type T, the Crosstooth structure, load transfer mode and force condition of flange joint system were analyzed. The mathematical model of flange loading, Cross-tooth structure parameters and bolted joint loading were built and compared with flat flange. With the method of finite element simulation, the simulation calculation of the screw connection system of Ttype face gear flange was carried out, the effects of Crosstooth structure parameters on bolted joint loading were investigated. The results indicate that Crosstoothtype T change the function of bolted joint. The load and load fluctuation on bolted joint are reduced. In addition, the bolted joint loading are influenced by Cross-toothstructure. The impacts of pressure angle and tooth number are more significant than others.
