It has several features which circular spur bevel gear (CSB gear) cannot realize. So far, NCSB gear is fab-ricated by using cutting method, and it is difficult to be fabricated by forging method because of its complicated shape and difficult forming accuracy control. This paper aims at studying the hot forging process of NCSB gear using FE simulation method. An elastic–plastic FE model for hot forging of NCSB gear is developed. Using the FE model, the evolution laws of the elastic deformation of dies, elastic deformation, and thermal expansion and contraction of NCSB gear during the hot forging process are comprehensively revealed. To improve the forming accuracy of NCSB gear, a compensation method for die cavity is proposed, and the compensation amount of die cavity is determined using FE simulation method. The transmission characteristics of the hot forged NCSB gear are also examined by using FE simulation method.KEYWORDS: FE simulation, non-circular spur bevel gear, accuracy evolution, hot forging
