制育秧缽機設計
 摘要：老式制育秧缽機由蜂窩煤成型機改進得來，體積龐大，結構復雜，成本高，效率低。本設計從老式制育秧缽機出發(fā)，在傳動系統(tǒng)和執(zhí)行機構上都做了很大的改進。本機每小時能生產3000個缽體，可廣泛應用于玉米、蔬菜、瓜果等秧苗的制缽。該機采用單相電動機做動力源，可在廣大的農村使用，不用擔心需要較高的動力電壓的問題。文中較詳細的設計了制育秧缽機的傳動系統(tǒng)和執(zhí)行機構，對各個零件做了具體的結構尺寸設計，并對受載荷較大的零件進行了精確的校核。包括齒輪、帶輪、軸和軸承等零部件的校核。該機的設計大量運用標準件，大大縮短了設計工作量和降低了生產制造周期及成本。主要設計內容有：方案的確定；電機的選擇；各軸的轉速、功率和轉矩計算；帶、齒輪、及錐齒輪的設計與計算；軸的最小直徑；帶、齒輪、及錐齒輪的尺寸計算以及方案圖、裝配圖和零件圖的繪制。

Design of the legacy of seedlings
Abstract: The old system of seedlings from the legacy of improvement in the briquettes machine, the size, structure complex, high cost and low efficiency. The design of the legacy from the old system of starting seedlings in the transmission system and executing agencies have done on a lot of improvement. The machine can produce per hour legacy of 4000, can be widely applied to corn, vegetables, fruits and other seedlings of the legacy system. The aircraft uses a single-phase motors to power source, can be used in the vast rural areas, need not worry about a higher power voltage problem. In a more detailed design of the system for the seedlings Bowl drive system and implementing agencies, the various parts to do a specific size of the structure design, and in the larger load of spare parts for the precise calibration. Including gear, pulley, and axle bearings and other parts of the check. The extensive use of the aircraft design standard parts, greatly reducing the workload of the design and lower manufacturing costs and manufacturing cycle. Main design elements include: the determination of the project, choice of Motor and the speed of every axial, the calculation of power and torque, the design and calculation of the belt or gear and the Bevel gear, the smallest diameter of axis, calculation to the size of belt wheel and gears and Bevel gear and protracting the drawing of the project and the assemblage and the part.
