课题简介 课题名称： A272F 型系列并条机车头箱设计 中文摘要： A272F 型系列并条机适应于 75mm 以下的纤维的纯纺与混纺，在纺纱工艺过程中，位于梳棉工序之后，梳棉纤维条经过本机并合与牵伸，能够提高纤维的条长片段均匀度、纤维的伸直度，使不同品质纤维的混合更趋均匀，为获得良好的细纱创造必要的条件。 2100 型号的车头箱是陕西宝鸡宝成纺织机械长的产品，年产量1000 台，车头箱是 A272F 型系列并条机的主要动力传递机构，它通过按一定的速比排布的齿轮将电机的动力经车头箱的变速，传递给各工作主轴，使其获得一定的动 力、转速和方向。 该车头箱是铸造而成，内部的零件主要由圆柱斜齿轮组成，齿轮要求加工精度较高，生产批量大。针对生产现状和要求设计 2100 型号的车头箱。 由被加工零件的不同，并条机设计方案各异，其车头箱可以垂直或水平安装。该设计的车头箱是水平安装在 A272F 高速并条机右侧上方的。 关键词 ：梳棉机，并条机，齿轮传动，车头箱 英文摘要 ： The A272F series drawing frame adapts below the 75mm textile fiberpurely spins with the fabric blending, in reels ntsthread in thetechnological process, after is located Carding machine the working procedure, Carding machine the textile fiber strip process this machine combines withextends, can enhance the textile fiber the strip long fragmentuniformity, the textile fiber unbends, causes the different qualitytextile fiber the mix to hasten evenly, for obtains the good spun yarncreation essential condition. 2,100 models front of a train boxes are the Shaanxi Baoji Paochi toChengtu textile machinery factory product, annual output 1,000, thefront of a train box are the A272F series drawing frame main powertransmission organizations, it through presses the certain speed ratiodistribution the gear the electrical machinery power after the frontof a train box speed change, transmits for each work main axle, causesit to obtain the certain power, the rotational speed and thedirection. This front of a train box is the casting becomes, the internalcomponents mainly are composed by the column helical gear, gearrequest processing precision higher, the production batch is big.Design 2,100 models in view of the production present situation andthe request the front of a train boxes. By is processed the components the difference, the drawing framedesign proposal respectively differently, its front of a ntstrain box maybe vertical or the level installment. This design front of a train boxis the level installs right flank the A272F high speed
