摘　　要：针对XK(H)2740数控龙门镗铣床主传动系统,使用等价误差法对其传动精度进行分析。在分析主变速箱结构形式及传动原理的基础上,较全面地分析影响其传动精度的主要因素,并建立传动精度非线性动力学模型。利用该模型对传动装置中各零件的加工误差、装配误差所引起的传动误差进行了研究,进而找到影响系统传动精度较大的误差因素。Transmission precision of princi-pal drive system for XK(H)2740, a CNC gantry boring and milling machine tool, is analyzed by error equivalent transformation method. On the ground of structure form and drive principle of gearbox, the main factors that affect transmission accuracy are studied and non-linear dynamic model of it is established. The transmission error caused by manufacture error and assembly error of each part is calculated to ifnd the one which is crucial for transmission accuracy, thus, the transmission accuracy can be improved through the analysis.
