產(chǎn)品名稱(chēng)： GFB/GFT系列回轉(zhuǎn)行星齒輪減速機(jī)
基本參數(shù)： 10
產(chǎn)品介紹：
GFB/GFT系列回轉(zhuǎn)行星齒輪減速機(jī):行星減速機(jī)系列采用德國(guó)技術(shù)，具有體積小、重量輕、傳遞扭矩大、起動(dòng)平穩(wěn)、低損耗、效率高、性能安全可靠、安裝方式多樣等優(yōu)點(diǎn)，可配電動(dòng)馬達(dá)或液壓馬達(dá)，內(nèi)部可安裝具有壓力釋放裝置的液壓多盤(pán)式停車(chē)制動(dòng)系統(tǒng)。
GFB/GFT系列回轉(zhuǎn)行星齒輪減速機(jī)：具有廣泛通用性的新性減速機(jī)，內(nèi)部齒輪采用20CvMnT滲碳淬火和磨齒。在建筑工程機(jī)械，煤炭洗選，濃縮設(shè)備而設(shè)計(jì)速比相對(duì)較大的系列新產(chǎn)品，特別適合中心和周邊傳動(dòng)的濃縮機(jī)使用，還可以港口吊車(chē)，建筑塔吊使用。負(fù)載啟動(dòng)性能比遠(yuǎn)有的電動(dòng)機(jī)加擺線(xiàn)針輪減速機(jī)的方案要提高很多，長(zhǎng)時(shí)間運(yùn)轉(zhuǎn)齒輪箱不發(fā)熱，噪音非常低并且可以替代國(guó)外相同類(lèi)型的行星減速機(jī)。該類(lèi)型減速機(jī)為適應(yīng)客戶(hù)要求設(shè)計(jì)了兩種輸出法蘭形式，以適應(yīng)不同工況要求。
參數(shù)：
輸出轉(zhuǎn)速：大減速比i=190
輸出轉(zhuǎn)矩：靜態(tài)扭矩2400KNM
電機(jī)功率：可選配液壓馬達(dá)A6V或A2F系列
應(yīng)用：
塔式起重機(jī)的、建筑工程機(jī)械、起重、挖掘、運(yùn)輸、建筑等行業(yè)。

4．分配IO點(diǎn)，編制出輸入輸出端子的接線(xiàn)圖。
5．設(shè)計(jì)應(yīng)用系統(tǒng)梯形圖程序，這一步是整個(gè)應(yīng)用系統(tǒng)設(shè)計(jì)核心的工作。
6．將程序輸入PLC，當(dāng)使用計(jì)算機(jī)上編程時(shí)，可將程序下載到PLC中。
7．進(jìn)行軟件測(cè)試，在將PLC連接到現(xiàn)場(chǎng)設(shè)備上之前，必須進(jìn)行軟件測(cè)試，以排除程序中的錯(cuò)誤。
8．應(yīng)用系統(tǒng)整體調(diào)試，在PLC軟硬件設(shè)計(jì)和控制柜及現(xiàn)場(chǎng)施工完成后，就可以進(jìn)行整個(gè)系統(tǒng)的聯(lián)機(jī)調(diào)試。調(diào)試中發(fā)現(xiàn)的問(wèn)題要逐一排除，直至調(diào)試成功。
9．編制技術(shù)文件， 系統(tǒng)技術(shù)文件包括功能說(shuō)明書(shū)、電氣原理圖、電器布置圖、電氣元件明細(xì)表、PLC梯形圖等。
PLC選型
在滿(mǎn)足控制要求的前提下，選型時(shí)應(yīng)選擇的性能價(jià)格比，具體應(yīng)考慮以下幾點(diǎn)。
1．性能與任務(wù)相適應(yīng)
2．PLC的處理速度應(yīng)滿(mǎn)足實(shí)時(shí)控制的要求
3．PLC應(yīng)用系統(tǒng)結(jié)構(gòu)合理、機(jī)型系列應(yīng)統(tǒng)一
4．在線(xiàn)編程和離線(xiàn)編程的選擇
PLC容量估算
PLC容量包括兩個(gè)方面：一是IO的點(diǎn)數(shù)，二是用戶(hù)存儲(chǔ)器的 容量。
1．IO點(diǎn)數(shù)的估算
根據(jù)功能說(shuō)明書(shū)，可統(tǒng)計(jì)出PLC系統(tǒng)的開(kāi)關(guān)量IO點(diǎn)數(shù)及模擬量IO通道數(shù)，以及開(kāi)關(guān)量和模擬量的信號(hào)類(lèi)型。應(yīng)在統(tǒng)計(jì)后得出IO總點(diǎn)數(shù)的基礎(chǔ)上，增加10％～15％的裕量。選定的PLC機(jī)型的IO能力極限值必須大于IO點(diǎn)數(shù)估算值，并應(yīng)盡量避免使PLC能力接近飽和，一般應(yīng)留有30％左右的裕量。
2. 存儲(chǔ)器容量估算
用戶(hù)應(yīng)用程序占用多少內(nèi)存與許多因素有關(guān)，如IO點(diǎn)數(shù)、控制要求、運(yùn)算處理量、程序結(jié)構(gòu)等。因此在程序設(shè)計(jì)之前只能粗略的估算。根據(jù)經(jīng)驗(yàn)，每個(gè)IO點(diǎn)及有關(guān)功能器件占用的內(nèi)存大致如下：
所需存儲(chǔ)器容量(KB)＝(1～1.25)×(DI×10＋DO×8＋AIO×100＋CP×300)1024
其中：DI為數(shù)字量輸入總點(diǎn)數(shù)；DO為數(shù)字量輸出總點(diǎn)數(shù)；AIAO為模擬量IO通道總數(shù)；CP為通信接口總數(shù)。
IO模塊的選擇
1．開(kāi)關(guān)量輸入模塊的選擇
PLC的輸入模塊用來(lái)檢測(cè)來(lái)自現(xiàn)場(chǎng)(如按鈕、行程開(kāi)關(guān)、溫控開(kāi)關(guān)、壓力開(kāi)關(guān)等)電平信號(hào)，并將其轉(zhuǎn)換為PLC內(nèi)部的低電平信號(hào)。開(kāi)關(guān)量輸入模塊按輸
