3.3 中置式電機(jī)
凡將驅(qū)動(dòng)電機(jī)裝在自行車腳踏處的這種安裝方式,其所采用的電機(jī)統(tǒng)稱為中置式電機(jī)。這類電機(jī)是通過(guò)鏈輪鏈條傳遞動(dòng)力至后輪。3.3.1普通無(wú)刷直流電機(jī)
這類電機(jī)即為通常使用的內(nèi)轉(zhuǎn)子式無(wú)刷直流電機(jī),電機(jī)結(jié)構(gòu)簡(jiǎn)單,已有相當(dāng)成熟的加工手段,電機(jī)成本較低。由于采用無(wú)刷控制,因此電機(jī)性能優(yōu)異。
3.3.2 普通永磁直流電機(jī)
這類電機(jī)是普通的永磁直流電機(jī),電機(jī)結(jié)構(gòu)簡(jiǎn)單,工作穩(wěn)定,可靠,生產(chǎn)加工成熟。定子可采用早期的鐵氧體永磁材料,也可采用當(dāng)今高性能稀土永磁材料釹鐵硼。采用鐵氧體磁鋼電機(jī)性能要差一些,但電機(jī)成本低一些;而采用釹鐵硼磁鋼電機(jī)性能將十分好,比如轉(zhuǎn)速低、效率較高、換向性能好等。

減速機(jī)一般用于低轉(zhuǎn)速大扭矩的傳動(dòng)設(shè)備,把電動(dòng)機(jī)、內(nèi)燃機(jī)或其它高速運(yùn)轉(zhuǎn)的動(dòng)力通過(guò)減速機(jī)的輸入軸上的齒數(shù)少的齒輪嚙合輸出軸上的大齒輪來(lái)達(dá)到減速的目的,普通的減速機(jī)也會(huì)有幾對(duì)相同原理齒輪達(dá)到理想的減果,大小齒輪的齒數(shù)之比,就是傳動(dòng)比。
1、降速同時(shí)提高輸出扭矩,扭矩輸出比例按電機(jī)輸出乘減速比,但要注意不能超出減速機(jī)額定扭矩;
2、減速同時(shí)降低了負(fù)載的慣量,慣量的減少為減速比的平方。
減速機(jī)使用方法
1、在運(yùn)轉(zhuǎn)200~300小時(shí)后,應(yīng)進(jìn)行次換油,在以后的使用中應(yīng)定期檢查油的質(zhì)量,對(duì)于混入雜質(zhì)或變質(zhì)的油須及時(shí)更換。一般情況下,對(duì)于長(zhǎng)期連續(xù)工作的減速機(jī),按運(yùn)行5000小時(shí)或每年一次更換新油,長(zhǎng)期停用的減速機(jī),在重新運(yùn)轉(zhuǎn)之前亦應(yīng)更換新油。減速機(jī)應(yīng)加入與原來(lái)牌號(hào)相同的油,不得與不同牌號(hào)的油相混用,牌號(hào)相同而粘度不同的油允許混合使用;
2、換油時(shí)要等待減速機(jī)冷卻下來(lái)無(wú)燃燒危險(xiǎn)為止,但仍應(yīng)保持溫?zé)?,因?yàn)橥耆鋮s后,油的粘度增大,放油困難。注意:要切斷傳動(dòng)裝置電源,防止無(wú)意間通電;
3、工作中,當(dāng)發(fā)現(xiàn)油溫溫升超過(guò)80℃或油池溫度超過(guò)100℃及產(chǎn)生不正常的噪聲等現(xiàn)象時(shí)應(yīng)停止使用,檢查原因,必須排除故障,更換潤(rùn)滑油后,方可繼續(xù)運(yùn)轉(zhuǎn);
4、用戶應(yīng)有合理的使用維護(hù)規(guī)章制度,對(duì)減速機(jī)的運(yùn)轉(zhuǎn)情況和檢驗(yàn)中發(fā)現(xiàn)的問(wèn)題應(yīng)作認(rèn)真記錄,上述規(guī)定應(yīng)嚴(yán)格執(zhí)行。
