系列变螺距螺杆的设计计算

为了使罐头包装机具有柔性加工的功能并提高设备利用率,根据圆柱形罐的螺杆供送机构的原理,设计开发了可调变螺距螺杆供送机构和对应不同罐径的系列变螺距螺杆。根据对罐的运动规律要求,给出了变螺距螺杆结构参数的设计计算方法以及罐的运动规律的计算分析方法。阐明了罐运动规律与螺杆长度、罐直径、螺距、螺距数之间的关系。研究的变螺距螺杆的设计计算及运动规律分析方法适合常用的罐径系列。

Design and calculation of a series of variable pitch screw

In order to improve the flexible manufacturing function of the can packing machine's efficiency,the adjustable variable pitch screw feeding mechanism and a series of variable pitch screw corresponding to different can diameter were designed and developed according to the principle of screw feeding mechanism for the cylindrical can.The structural parameters design and calculation method for variable pitch screw and the calculation and analysis method of can movement rule were provided based on the motion rule of can.The relationship among the can movement rule,the screw length,the can diameter,the pitch and the pitch quantity was illustrated.The method of variable pitch screw design and calculation and movement rule analysis can be applied to the commonly used tank diameter series.
