营养钵制钵机的设计
摘要：以前老式的制钵机体积庞大，结构复杂，制作成本高，效率比较低。我的设计以老式的制钵机为源头对其进行分析与改进。该机器每小时能生产2500个营养钵，制作出来的营养钵可以用于农作物的育秧以及移植。选用功率为1.1千瓦的电动机作为动力源，可以满足在农村或农场使用，不必担心电压不足的问题。本文重点对制钵机的传动系统和执行机构进行详细的分析与设计，对各个零部件认真的做了结构尺寸设计，并且受力较大的零部件进行了强度校核。包括了齿轮、皮带轮、轴等零件的校核。在设计时灵活使用标准件，大大缩短了设计的工作量并且在设计和制作时也能节约大量时间以及成本。本文的主要涉及内容包括：方案的确定、电动机的选择、各轴的转速及功率计算、皮带及齿轮的设计与计算还有轴的直径以及齿轮的尺寸设计计算。最终绘制出零件图与装配图。

Design of nutrition bowl making machine
Abstract：In the past, the old bowl making machine had large volume, complex structure, high production cost and low efficiency. My design takes the old bowl making machine as the source to analyze and improve it. The machine can produce 2500 nutrition bowls per hour, which can be used for seedling raising and transplanting of crops. The motor with power of 1.1KW is selected as the power source, which can be used in rural areas or farms without worrying about the problem of insufficient voltage. This paper focuses on the detailed analysis and design of the transmission system and actuator of the bowl making machine, carefully designs the structure and size of each part, and checks the strength of the parts with larger force. Including gear, pulley, shaft and other parts of the check. Flexible use of standard parts in design greatly reduces the workload of design, and also saves a lot of time and cost in design and production. The main contents of this paper include: the determination of the scheme, the selection of the motor, the calculation of the speed and power of each shaft, the design and calculation of the belt and gear, as well as the design and calculation of the diameter of the shaft and the size of the gear. Finally, the part drawing and assembly drawing are drawn.
