制育秧缽機(jī)設(shè)計(jì)
學(xué)生姓名：馮 杰 班級(jí)：050313
指導(dǎo)老師：吳暉
摘要：老式制育秧缽機(jī)由蜂窩煤成型機(jī)改進(jìn)得來，體積龐大，結(jié)構(gòu)復(fù)雜，成本高，效率低。本設(shè)計(jì)從老式制育秧缽機(jī)出發(fā)，在傳動(dòng)系統(tǒng)和執(zhí)行機(jī)構(gòu)上都做了很大的改進(jìn)。本機(jī)每小時(shí)能生產(chǎn)4000個(gè)缽體，可廣泛應(yīng)用于玉米、蔬菜、瓜果等秧苗的制缽。該機(jī)采用單相電動(dòng)機(jī)做動(dòng)力源，可在廣大的農(nóng)村使用，不用擔(dān)心需要較高的動(dòng)力電壓的問題。文中較詳細(xì)的設(shè)計(jì)了制育秧缽機(jī)的傳動(dòng)系統(tǒng)和執(zhí)行機(jī)構(gòu)，對(duì)各個(gè)零件做了具體的結(jié)構(gòu)尺寸設(shè)計(jì)，并對(duì)受載荷較大的零件進(jìn)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(jī)的設(shè)計(jì)大量運(yùn)用標(biāo)準(zhǔn)件，大大縮短了設(shè)計(jì)工作量和降低了生產(chǎn)制造周期及成本。主要設(shè)計(jì)內(nèi)容有：方案的確定；電機(jī)的選擇；各軸的轉(zhuǎn)速、功率和轉(zhuǎn)矩計(jì)算；帶、齒輪、及錐齒輪的設(shè)計(jì)與計(jì)算；軸的最小直徑；帶、齒輪、及錐齒輪的尺寸計(jì)算以及方案圖、裝配圖和零件圖的繪制。

Design of the legacy of seedlings
Student: Feng Jie class : 050313
Supervisor : Wu hui
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.
Key words: the legacy of the legacy of seedlings Bowl transmission system Implementing agencies
