承重梁構造

1，承重(zhong)梁選用歐式古(gu)典箱(xiang)型梁組織(zhi)設計方案，重(zhong)量輕，合理(li)配置；

2，整個PCB線路板制(zhi)做，無對接焊縫，比拼湊承重梁(liang)更牢固。

3，豎直(zhi)剛度為(wei)1/800，梁端拱(gong)度由數控(kong)切割整個(ge)PCB線(xian)路板開(kai)料，精準度高。

4，選用埋弧焊自動焊、無損檢測。焊后(hou)總(zong)體拋丸除銹，消地應力、防銹處理，超過Sa2.5級；

5，厚(hou)鋼板原材(cai)料為Q235B；環氧(yang)富鋅漆，薄厚(hou)120μm。

端梁一部分

1，端梁(liang)選用絞接軟(ruan)性設(she)計方案，防止(zhi)“幾條腿”運作。

2，車轱(gu)轆選用鏜(tang)孔(kong)方式，應用數控機床(chuang)鏜(tang)銑床(chuang)一回精準定位生產加工，保證規格精密度(du)和(he)配合尺(chi)寸(cun)；

3，每一端梁裝(zhuang)有雙輪緣的車轱轆(lu)、緩(huan)沖器、驅動器維護和防外遇保護器，安全性有確保。

4，承重梁與(yu)端梁選(xuan)用10.9級高強(qiang)螺栓聯接，保證整(zheng)個設備構造抗壓強(qiang)度和精密度。

5，半今龍門端梁選用矩(ju)形方管(guan)制(zhi)做，車(che)轱轆為無邊緣(yuan)設計方案(an)，路軌(gui)與路面每平(ping)米。

小轎車總程

1，雙(shuang)梁小(xiao)轎車承重(zhong)梁與承重(zhong)梁選(xuan)用軟性絞接方式；防止(zhi)“幾條腿”運作。

2，電動機(ji)＋制(zhi)動系統＋減速器＋行程開關四合一一體化設(she)計方(fang)案(an)，結(jie)構緊湊(cou)

3，小轎車搭建有安全性鉤，防失(shi)控。

4，全(quan)部傳動(dong)系統組織選用無連軸器的(de)立即I/O方式，傳動(dong)系統高(gao)效(xiao)率、裝配線高(gao)精度(du)、免維護保(bao)養。

5，工作中級(ji)別為A6級(ji)，防(fang)(fang)(fang)水等級(ji)IP55，H級(ji)絕(jue)緣(yuan)層(ceng)。防(fang)(fang)(fang)污防(fang)(fang)(fang)潮，提升安全級(ji)別。
