摘　　要：在快开式硫化罐卡箍结构啮合处设置覆层结构可以有效保护啮合齿面,为提高检修效率,课题组设计了一种用于卧式双开门硫化罐的新型覆层卡箍结构,并运用有限元法进行应力强度评定,分析覆层结构参数对硫化罐覆层结构应力分布影响。结果表明:圆柱销直径由4.0 mm增大至7.0 mm,开槽数由2增大至4时,覆层板销孔处最大应力增幅分别为71.5%和68.5%,圆柱销直径和开槽数对覆层板销孔处应力影响较大;覆层结构各参数对圆柱销最大剪切应力影响均较大;圆柱销开槽数为2时相比不开槽结构,其表面最大接触应力增幅达198.5%,圆柱销表面最大接触应力受其开槽数影响较大。当圆柱销直径为5.0 mm、圆柱销开槽数为2及覆层板厚度为5.0~6.0 mm时,覆层卡箍结构综合力学性能较好。The clamping structure of the quick-opening vulcanization tank is equipped with a coating structure at the engagement point,which can effectively protect the meshing tooth surface and improve maintenance efficiency.Research group designed a new type of coated clamping structure for a horizontal double-door vulcanization tank and used the finite element method to evaluate stress intensity,analyzed the influence of coating structure parameters on the stress distribution of coating structure of the vulcanization tank.The results show that when the diameter of the cylindrical pin increases from 4.0 mm to 7.0 mm and the number of grooves increases from 2 to 4,the maximum stress at the pin hole of the coating plate increases by 71.5%and 68.5%,respectively.The diameter of the cylindrical pin and the number of grooves have a significant influence on the stress at the pin hole of the coating plate.Various parameters of the coating structure have a considerable effect on the maximum shear stress of the cylindrical pin.The maximum contact stress on the surface of the cylindrical pin is greatly influenced by the number of grooves;specifically,the maximum contact stress on the surface of the cylindrical pin with 2 grooves increases by 198.5%compared to the structure without grooves.When the diameter of the cylindrical pin is 5.0 mm,the number of grooves is 2,and the thickness of the coating plate is 5.0-6.0 mm,the coated clamping structure exhibits better comprehensive mechanical performance.
