??? 這篇畢業(yè)設(shè)計主要闡述的是管道除銹機(jī)的設(shè)計，管子除銹是管子使用前的一項重要工序，尤其是在鋼管使用后非常有必要對管道進(jìn)行除銹。這對鋼管的使用壽命有著很重要的意義。
本設(shè)計方案是：該機(jī)主要由機(jī)架、電動機(jī)、變速傳動機(jī)構(gòu)、主軸、鋼絲刷、圓盤機(jī)構(gòu)等組成。除銹由電機(jī)帶動，通過普通圓柱蝸輪蝸桿減速器來減速。蝸桿傳動是用來傳遞空間互相垂直的兩項錯軸之間的運動和動力的一種機(jī)械傳動形式。由于蝸輪蝸桿傳動可以實現(xiàn)自鎖，傳動比大，噪音小的原因，所以選擇蝸輪蝸桿傳動。
現(xiàn)有的除銹機(jī)，其體積大，不宜搬動，而且把管道固定在機(jī)床上后，需要人力用砂紙打磨，一般總共需要3-4個人來工作。耗費人力不說，并且工作環(huán)境非常惡劣。
本設(shè)計是在機(jī)械動力頭的基礎(chǔ)上，增加適當(dāng)?shù)牧慵?，實現(xiàn)金屬管子機(jī)械化除銹工作，達(dá)到成本較低、結(jié)構(gòu)合理、勞動強(qiáng)度低、效率高的目的。
本設(shè)計需要明確設(shè)計任務(wù)，由相關(guān)的任務(wù)書和工具書確定設(shè)計的傳動方案為機(jī)械傳動。由以知條件，可計算出工作力和工作速度。選電機(jī)，擬定兩級減速的各個傳動比，確定各級減速的輸入輸出功率、轉(zhuǎn)速、轉(zhuǎn)矩。其次，查找主要技術(shù)參數(shù)，明確設(shè)計原則，由相關(guān)的公式進(jìn)行軸及各類零件的強(qiáng)度，穩(wěn)定性及壽命的校核計算；進(jìn)行機(jī)架的設(shè)計，包括床身，加緊裝置形式的明確和對其強(qiáng)度，剛度，穩(wěn)定性的校核計算。最后，全面分析設(shè)計結(jié)果是否符合設(shè)計要求，完善各個細(xì)節(jié)。???????????

Abstract
???? This graduation project is a pipeline of major rust on the machine design, the tube removing is an important process of the tube before using, especially in the steel pipe is used it is necessary to rust pipes. This pipe has a life of significance.
This designed plan is consisted mainly by the rack, electric motors, variable speed transmission, spindle, steel wire brush, disc component institutions. Rust by the motor driven by ordinary cylindrical worm gear reducer to slow down. Worm-drive space is used to pass each other the wrong vertical axis between the two campaigns and a dynamic form of mechanical transmission. As the worm drive can achieve self-locking, the transmission ratio, and noise reasons, so I chose to drive worm.
Removing the existing machine, its size should not be moving, and the pipe is fixed in the machine tool, the need for human polished with sandpaper, generally a total of 3-4 individuals to work. Labor-to say the least, and very bad work environment.
This design is the first in the mechanical power on the basis of the increase in the appropriate parts, the realization of mechanization rust metal pipe work, low cost, reasonable structure, low labor intensity, high efficiency purposes.
The design needs a clear designed mandate, and the mandate of the relevant books and reference books to determine the design for the mechanical drive transmission. Known by the conditions, we can calculate of the speed and force. Motor selection and preparation of all two reducer transmission ratio can determine the speed at all levels of input and output power, speed and torque. Second, find the main technical parameters, a clear design principles, by the axis of the formula and various parts of the strength, stability and the check calculation of life expectancy; for rack design, including the bed, stepping up device and the form of a clear its strength, stiffness, stability, the calculation of the check. Finally, comprehensively analyze the results of the design with the design requirements and perfect in all details.
