減速機技術資料：

行星減速機主要傳動結構為:行星輪,太陽輪,外齒圈. 
行星減速機因為結構原因,單級減速最小為3,最大一般不超過10,常見減速比為:3.4.5.6.8.10,減速機級數一般不超過3,但有部分大減速比定制減速機有4級減速.
相對其他減速機,行星減速機具有高剛性,高精度(單級可做到1分以內),高傳動效率(單級在97%-98%),高的扭矩/體積比,終身免維護等特點.
因為這些特點,行星減速機多數是安裝在步進電機和伺服電機上,用來降低轉速,提升扭矩,匹配慣量.
減速機額定輸入轉速最高可達到18000rpm(與減速機本身大小有關,減速機越大,額定輸入轉速越小)以上,工業級行星減速機輸出扭矩一般不超過2000Nm,特制超大扭矩行星減速機可做到10000Nm以上.工作溫度一般在-25℃到100℃左右,通過改變潤滑脂可改變其工作溫度.
關于行星減速機的幾個概念:
級數:行星齒輪的套數.由于一套星星齒輪無法滿足較大的傳動比,有時需要2套或者3套來滿足擁護較大的傳動比的要求.由于增加了星星齒輪的數量,所以2級或3級減速機的長度會有所增加,效率會有所下降.
回程間隙:將輸出端固定,輸入端順時針和逆時針方向旋轉,使輸入端產生額定扭矩+-2%扭矩時,減速機輸入端有一個微小的角位移,此角位移就是回程間隙.單位是"分",就是一度的六十分之一.也有人稱之為背隙.

行星減速機是一種用途廣泛的工業產品，其性能可與其它軍品級減速機產品相媲美，卻有著工業級產品的價格，被應用于廣泛的工業場合。
該減速器體積小、重量輕，承載能力高，使用壽命長、運轉平穩，噪聲低。具有功率分流、多齒嚙合獨用的特性。最大輸入功率可達104kW。適用于起重運輸、工程機械、冶金、礦山、石油化工、建筑機械、輕工紡織、醫療器械、儀器儀表、汽車、船舶、兵器和航空航天等工業部門行星系列新品種WGN定軸傳動減速器、WN子母齒輪傳動減速器、彈性均載少齒差減速器。
行星減速機是一種具有廣泛通用性的新性減速機，內部齒輪采用20CvMnT滲碳淬火和磨齒。整機具有結構尺寸小，輸出扭矩大，速比在、效率高、性能安全可靠等特點。本機主要用于塔式起重機的回轉機構，又可作為配套部件用于起重、挖掘、運輸、建筑等行業。
