多功能電動跑步機
（機械部分）
摘要
跑步機是家庭及健身房常備的器材，而且是當今家庭健身器材中最簡單的一種，是家庭健身器的最佳選擇。專家們相信未來跑步機市場將以高價位產(chǎn)品為主導。低價位產(chǎn)品銷售也不錯，近幾年價格已有上升趨勢。注重生活時尚的消費者認為跑步機價格在 1000美元以上是理所當然的事。這些跡象表明，未來跑步機仍會持續(xù)增長。
此次設計的任務為學習相關三維軟件并使用軟件進行電動跑步機機械部分的零件建摸，結(jié)構(gòu)設計，產(chǎn)品的裝配，和最后出產(chǎn)品的渲染圖，發(fā)布產(chǎn)品的宣傳海報。設計過程中使用了三維實體軟件SOLIDWORKS進行了零件的實體建模，和總體結(jié)構(gòu)的設計。設計包括支架，基架，滾筒，跑步板，跑步帶等，設計中參考了國內(nèi)外各品牌結(jié)構(gòu)和樣式，對傳動機構(gòu)進行了精確計算，而且設計中重點突出了減震系統(tǒng)的重要性和跑步板防靜電的功能性，設計更為人性化，使跑步者能感受到跑步機的力量。
由于跑步機的特殊性，安全問題更值關注，如何正確使用跑步機，和跑步機的保養(yǎng)同樣重要。
關鍵詞：總體結(jié)構(gòu)；傳動機構(gòu)；減震系統(tǒng)；跑步板；跑步機使用；多功能設計
Abstract
The race apparatus is the family and apparatus always on the alert of gymnasium, and the simplest one in the body-building apparatus of the current family, it is the best choice of the family building up body device . The experts believe the race apparatus market will take high price products as the leading factor in the future. Low price products sell too good, price in recent years had the tendency to rise. Pay attention to consumers with fashionable life and think the price of the race apparatus is the natural thing above 1000 U.S. dollars. These signs indicate , the race apparatus will still increase continuously in the future.
Have used the three-dimensional entity software SOLIDWORKS to carry on the entity modeling of the part in the course of designing, design with the ensemble architecture . Design and include the support , the base shelf , the cylinder , run board, is it bring to run, design consult domestic and international every brand structure and design, carry on accurate calculation by organization to transmission, and design stress shock attenuation systematic importance and run the static -proof functionality of the board especially, the design enables persons who run to experience the strength of the race apparatus.
Because of the particularity of the race apparatus, safe problem is worth paying close attention toer, how to use the race apparatus correctly, it is as important as maintenance of the race apparatus.
