減速器在原動機和工作機或執(zhí)行機構(gòu)之間起匹配轉(zhuǎn)速和傳遞轉(zhuǎn)矩的作用,在現(xiàn)代機械中應用極為廣泛。減速器按用途可分為通用減速器和專用減速器兩大類,兩者的設計、制造和使用特點各不相同。20世紀70-80年代,上減速器技術(shù)有了很大的發(fā)展,且與新技術(shù)革命的發(fā)展緊密結(jié)合。
減速器是原動機和工作機之間的獨立的閉式傳動裝置,用來降低轉(zhuǎn)速和增大轉(zhuǎn)矩,以滿足工作需要,在某些場合也用來增速,稱為增速器。
選用減速器時應根據(jù)工作機的選用條件,技術(shù)參數(shù),動力機的性能,經(jīng)濟性等因素,比較不同類型、品種減速器的外廓尺寸、傳動效率、承載能力、質(zhì)量、價格等,選擇的減速器。
減速器是一種相對精密的機械,使用它的目的是降低轉(zhuǎn)速,增加轉(zhuǎn)矩。

一些關(guān)系到整體產(chǎn)品穩(wěn)定性的小配件,大家一定要多留意、詢問和了解,才能確保大件家具使用時間更長久。某品牌衣柜銷售員鄭女士建議消費者,因為消費者每天都在使用這些小配件,它們屬于易磨損的消耗品,建議大家在選購家居產(chǎn)品時,一定不要以價格去對比質(zhì)量和選購標準,摸清產(chǎn)品間用的配件區(qū)別在哪里,就知道價格差的原因了。怎樣安裝也非常重要除了配件質(zhì)量很關(guān)鍵外,安裝也很有講究。正規(guī)家居產(chǎn)品的銷售過程中,都會有自家的專門安裝師傅上門安裝,他們憑借自己的多年經(jīng)驗,會將小配件一一安裝到位,確保產(chǎn)品更加穩(wěn)固、牢靠。

交流伺服電機及其調(diào)速分類和特點
長期以來,在要求調(diào)速性能較高的場合,一直占據(jù)主導地位的是應用直流電動機的調(diào)速系統(tǒng)。但直流電動機都存在一些固有的缺點,如電刷和換向器易磨損,需經(jīng)常維護。換向器換向時會產(chǎn)生火花,使電動機的速度受到限制,也使應用環(huán)境受到限制,而且直流電動機結(jié)構(gòu)復雜,制造困難,所用鋼鐵材料消耗大,制造成本高。而交流電動機,特別是鼠籠式感應電動機沒有上述缺點,且轉(zhuǎn)子慣量較直流電機小,使得動態(tài)響應更好。在同樣體積下,交流電動機輸出功率可比直流電動機提高10﹪~70﹪,此外,交流電動機的容量可比直流電動機造得大,達到更高的電壓和轉(zhuǎn)速。現(xiàn)代數(shù)控機床都傾向采用交流伺服驅(qū)動,交流伺服驅(qū)動已有取代直流伺服驅(qū)動之勢。
