NAF450-8-I型行星减速器设计含4张CAD图+说明书
NAF450-8-I型行星减速器设计 [摘要]:此次设计的题目是NAF450-8-1型行星齿轮减速器。该行星齿轮减速器的主要构成为一个太阳轮,三个行星轮和一个齿圈,两个轴等。 本次设计主要研究内容: (1)行星齿轮的传动设计 其中包括传动比的确定和具体分配,还有传动的方式的选定。 (2)行星齿轮的尺寸数据计算 其中包括配尺的计算,装配条件的计算,传动效率的计算,结构设计计算,输入、输出端的尺寸计算和其他主要构件的数据计算。 (3)行星齿轮传动强度的校核 其中包括各啮合齿轮的疲劳强度校核等 (4)装配图以及各零件图的设计。 本次设计的NAF450-8-I行星齿轮减速器需要体积尽可能孝重量尽量轻、工作平稳、结构合理,承载能力强等,要已以上条件进行装备结构的设计计算,使用AutoCAD进行二维装备图及零件图的设计。 [关键词]:减速器;行星齿轮,太阳轮,法兰 Desig
