【正文】 鼠籠式交流電機(jī) 更好使用由于其便于建設(shè)和使用方便,還有高效且相對(duì)便宜的導(dǎo)頻率設(shè)備或頻率轉(zhuǎn)換器是可以使用的。當(dāng)較少或沒有人員被傳送時(shí),第一馬達(dá) M1的驅(qū)動(dòng)力可能足夠,那么發(fā)動(dòng)機(jī)馬達(dá) M2到 Mn保持關(guān)閉。在此之上,整個(gè)驅(qū)動(dòng)通過一個(gè)主繼電器或幾個(gè) 15連接,在緊接著看有一個(gè)導(dǎo)頻率裝置 16,導(dǎo)頻率裝置通過繼電器控制 23的中繼站 S S2,到 Sn給驅(qū)動(dòng)橫塊 7的馬達(dá) ( M1, M2到 Mn)供給以變頻交流電并控制驅(qū)動(dòng)的旋轉(zhuǎn)方向。 7驅(qū)動(dòng)主驅(qū)動(dòng)輪 通過輸出齒輪 7和中間齒輪 輪 6的周圍。鼠籠式多相交流變頻電機(jī)的使用和相關(guān)控制可以實(shí)現(xiàn)在低圓周速 度時(shí)產(chǎn)生大扭矩。 還有,這種分別驅(qū)動(dòng)裝備行星輪,導(dǎo)致較高的成本,該發(fā)明的目標(biāo)是創(chuàng)造一種方法,以較低的成本模塊化建設(shè)的方法,更廣泛的的應(yīng)用空間。 FIG. 4 shows a threedimensional illustration of the drive arrangement according to FIG. 2。 FIG. 5 shows a threedimensional illustration of the drive arrangement according to FIG. 3。 簡(jiǎn)述該發(fā)明: 由此發(fā)明,該驅(qū)動(dòng)由多個(gè)相同單元,分布在主驅(qū)動(dòng)輪的周圍,因此主驅(qū)動(dòng)輪或其邊齒僅需要根據(jù)每一驅(qū)動(dòng)單元的負(fù)載計(jì)算。 示意插圖簡(jiǎn)述 : 通過以下具體設(shè)備的插圖,可以更細(xì)致地說明本說明,如下圖,其中, FIG1表示本驅(qū)動(dòng)布置在上端的自動(dòng)扶梯 FIG2由進(jìn)過凸像安裝處理的驅(qū)動(dòng)單元組成的驅(qū)動(dòng),主動(dòng)輪橫向地朝著自動(dòng)扶梯的運(yùn)動(dòng)方向。主驅(qū)動(dòng)輪 6和二階梯齒輪 被固定在驅(qū)動(dòng)的主軸 4上通過三個(gè)平面凸像連接孔 24,驅(qū)動(dòng)單元 7被牢固的連接在主齒輪箱 8當(dāng)需要少于 3個(gè)驅(qū)動(dòng)單元 7時(shí),多余的凸像連接孔 24可以被蓋子關(guān)閉,不再插入相關(guān)中間齒輪 同的主齒輪箱 8可以根據(jù)需要使用 1個(gè)、 2個(gè)或 3個(gè)驅(qū)動(dòng)單元 7的輪 軸被縱向的安裝在自動(dòng)扶梯 1的運(yùn)動(dòng)方向上,以此可以節(jié)省空間。馬達(dá)( M1, M2到 Mn)經(jīng)由齒輪 21連接到主驅(qū)動(dòng)輪6,此前已描述,在 此不再贅述,為了測(cè)量馬達(dá)( M1, M2到 Mn)的實(shí)際機(jī)械載荷量, ,扭矩傳輸設(shè)備 20( L1, L2到 Ln)被安裝在變速箱的馬達(dá)( M1, M2到 Mn)之間,這需要很高的技術(shù),主驅(qū)動(dòng)輪 6通過一個(gè)合適的變速起來驅(qū)動(dòng)速度傳輸裝置19,不再詳述。如果扭據(jù)傳感器 L1監(jiān)測(cè)到滿負(fù)荷并有持續(xù)過載的趨勢(shì),馬達(dá) M2在規(guī)定的時(shí)間后開啟,來自兩個(gè)扭轉(zhuǎn)傳感器 L1和 L2的信號(hào)現(xiàn)在被調(diào)控單元 10監(jiān)測(cè),根據(jù)模擬標(biāo)準(zhǔn)當(dāng)載荷超過馬達(dá) M1和 M2的在和極限值時(shí),馬達(dá) M3可以啟動(dòng)。正常的直齒輪可以達(dá)到最佳的機(jī)械效率,根據(jù) FIG2可以用于驅(qū)動(dòng)布置。在驅(qū)動(dòng)模塊 7中也可以經(jīng)過適當(dāng)改進(jìn)的調(diào)控技術(shù)工藝的直流電機(jī)。來自扭矩傳感器 20的輸入數(shù)據(jù)鏈 ,提供關(guān)于開動(dòng)的驅(qū)動(dòng)模塊 7( M1, M2到 Mn)的機(jī)械載荷量的信息。驅(qū)動(dòng)的電流供應(yīng)通向主開關(guān) 14通常是當(dāng)?shù)赜?R、 S、 T三相。 FIG2安裝了傳輸結(jié)構(gòu) 9的驅(qū)動(dòng)的細(xì)節(jié),在自動(dòng)扶梯 1的上端 2,3個(gè)同樣安裝的驅(qū)動(dòng)單元??刂普{(diào)節(jié)單元根據(jù)輸出信息發(fā)出相關(guān)的調(diào)控指令,還根據(jù)扭矩傳遞裝置的實(shí)際載荷數(shù)據(jù)控制各個(gè)驅(qū)動(dòng)單元的開關(guān),以此可以提高電力和機(jī)械效率,從而降低能源消耗。這種建設(shè)方法有很多變型,對(duì)于階梯鏈或平面鏈,需要有許多不同的齒輪和齒輪箱。 FIG. 3 shows the drive with drive units flangemounted on a main gear longitudinally of the direction of travel of the escalator。 and FIG. 6 shows a block schematic diagram and functional diagram of the drive with all associated ponents. DETAILED DESCRIPTION OF THE INVENTION FIG. 1 shows an escalator 1 with an upper end 2, below which drive units denoted by 7 and a part of a stair chain 3 are visible. FIG. 2 shows the details of a drive, which is installed within a carrying structure 9 at the upper end 2 of the escalator 1. Three identically constructed drive units 7 drive a toothed main drive wheel 6 by way of an output gearwheel and an intermediate gearwheel 21, and are arranged and distributed about the circumference of the main drive wheel 6. The main drive wheel 6, together with a stair chain wheel 5, are fastened on the main shaft 4 of the drive. The drive units 7 are firmly connected to a main gear housing 8 at three planar flangeconnecting openings 24 formed for this purpose. When less than three drive units 7 are needed, the unused flangeconnecting opening 24 may be closed by a cover and the associated intermediate gearwheel 21 is not inserted. With this construction, the same main gear housing 8 can always be used for one, two or three needed drive units 7. The axles of the drive units 7 are arranged transversely to the direction of movement of the escalator 1, which yields the advantage of a short machine room. As example of a variant, FIG. 3 shows an arrangement of the drive units 7 parallel to the direction of movement of the escalator 1. In this manner of arrangement, the drive units 7 additionally
