NGW行星齿轮减速机.doc

NGW行星齿轮减速机特点和适用范围构造特点NGW型行星齿轮减速机主要构建有太阳轮、行星轮、内齿圈、行星架为了使三个行星轮的载荷均匀分配，采用了齿式浮动机构，即太阳轮或行星架浮动，或者太阳轮、行星架两者同时浮动减速机中的齿轮为直齿渐开线圆柱齿轮具有一下特点：1、体积小、重量轻、在一样情况下，比普通渐开线圆柱齿轮减速机重量轻1/2以上，体积小1/2～1/32、传动效率高：单级行星齿轮减速机达97％～98％；两级行星齿轮减速机达94％～96％；三级行星齿轮减速机91％～94％3、传动功率范围大：可以从小于1KW至1300KW，甚至更大4、传动范围大：i＝2.8～20005、适应性强且耐用主要零件均采用优质合金钢经渗碳淬火或氮化处理，行星齿轮减速机运转平稳、噪音小、使用受命10以上6、用途和适用条件NGW型行星齿轮减速器有单级〔NGW11—NGW121〕，两级〔NGW42—NGW122〕三级 〔NGW73—NGW123〕三个卧式系列主要用于冶金、矿山、起重运输机械设备，也可用于其它类似工矿条件下作动力传动高速轴最高速不超过1500r/min齿轮圆周速度不超过10m/s；工作环境温度为－40℃—45℃；可正反两向运转。

NGW型行星齿轮减速器的一个重要特点是，内啮合于外啮合之间共用一个行星轮，NGW就是由“内、公、外〞三字的汉语拼音的第一个字母组成的本系列减速器的规格的规定是根据传动比、功率和扭矩大小划分成12个机座号，及单级、双级和三级传动，共有27个机座号，58种速比，详细如下：传动类别型号规格传动比组成台数机座号种数范围种数单级NGW42—NGW121122.8—12.51412×14＝168双级NGW42—NGW122914—160229×22＝198三级NGW73—NGW1236180—200226×22＝132NGW单级减速器外形尺寸型号规格公称传动比i0外形及中心高轴伸地脚尺寸质量kgLBHH0RdDl1l2t1b1t2b2L1L2L3L0B1d1hNGW112.8-4.5530280295125 0 -0.51253550558538.510551621516525105220M1620535-12.547730503385750NGW212.8-4.5604305325140 0 -0.514040607010543.51265.51824518530115.5235M2025805-12.5535355538.51060.573NGW312.8-4.5632350365160 0 -0.51604570701054914762026020030125270M20251005-12.5569407043.5126298NGW412.8-4.5734380425.5180 0 -0.51805080851055516872429023030156320M24301475-12.56344570501472128NGW512.8-4.5845420463.5200 0 -0.52005590851156016972431025030196.5360M24352135-12.57295085551680.5193NGW612.8-4.5886475524225 0 -0.52256010010512565.5181082836029035202.5405M30402895-12.57315585601667.5264NGW712.8-4.5933535574250 0 -0.52506511010514070.5181193237530535213465M30403595-12.58006010565.51880301NGW812.8-4.51042590634280 0 -0.52807512011516081201293244035045219510M36454495-12.58996510570.51886399NGW912.8-4.51141660721315 0 -0.53158513012516592241403647538545225.5570M36456045-12.597675115812070.5542NGW1012.8-4.51261745800355 0 -0.535595150140200103281614052542550251645M42508105-12.5107385125922478732NGW1112.8-4.51355840891400 0-0.5400105170160200113281814058048050263740M425510605-12.51145951401032873990NGW1212.8-4.515009501013450 0 -0.5455115190160240124322024568056060288820M486016385-12.5128610516011328731475NGW两级减速器外形尺寸型号规格公称传动比i0外形及中心高轴伸地脚尺寸质量/kgLBHH0RdDl1l2t1b1t2b2L1L2L3L0B1d1hNGW4214-22.5687380425.5180 0 -0.518035805510528.51087242902303072320M243012825-1606873055338130NGW5214-22.5767420463.5200 0 -0.520040907011543.51297243102503080.5360M243524425-160752355538.510241NGW6214-22.5805.5475524225 0 -0.522545100701254914108283602903567.5405M304029125-160805.5407043.512279NGW7214-22.5890535574250 0 -0.525050110851405516119323753053580465M304035025-16087545704914350NGW8214-22.5976.5590634280 0 -0.528055120851606016129324403504586510M364548825-160976.550855516460NGW9214-22.51040660721315 0 -0.53156013010516565.518140364753854570.5570M364560725-160102055856016577NGW10214-22.51144745800355 0 -0.53556515010520070.518161405254255078645M425089525-16011446010565.518895NGW11214-22.51222840891400 0 -0.5400751701152008120181405804805073740M4255112025-16012126510570.5181075NGW12214-22.513859501013450 0 -0.5455851901252409224202456805606073820M4860173325-16013757511581201539NGW73、NGW83、NGW93、NGW103、NGW113、NGW123、三级减速器外形尺寸型号规格公称传动比i0外形及中心高轴伸地脚尺寸质量/kgLBHH0RdDl1l2t1b1t2b2L1L2L3L0B1d1hNGW73180-2000973.5535574250 0 -0.52503011055140338119323753053580465M3040382NGW831071590634280 0 -0.5280351205516038.5101293244035。
