摘要:本课题是有关一种自动洗衣机减速离合器内部减速装置行星轮系减速器的设计。在洗衣机中使用行星轮系减速器正是利用了行星齿轮传动:体积小，质量小，结构紧凑，承载能力大;传动效率高;传动比较大;运动平稳、抗冲击和震动的能力较强、噪声低的特点。行星轮减速其实就是齿轮减速的原理,它有一个轴线位置固定的齿轮叫中心轮或太阳轮,在太阳轮边上有轴线变动的齿轮,即既作自转又作公转的齿轮叫行星轮,行星轮有支持构件叫行星架,通过行星架将动力传到轴上,再传给其它齿轮.它们由一组若干个齿轮组成一个轮系.只有一个原动件,这种周转轮系称为行星轮系.(毕业设计网 )
关键词:行星轮系减速器、行星轮、中心轮、行星架。

行星轮系减速器较普通齿轮减速器具有体积小、重量轻、效率高及传递功率范围大等优点，逐渐获得广泛应用。同时它的缺点是:材料优质、结构复杂、制造精度要求较高、安装较困难些、设计计算也较一般减速器复杂。但随着人们对行星传动技术进一步的深入地了解和掌握以及对国外行星传动技术的引进和消化吸收，从而使其传动结构和均载方式都不断完善，同时生产工艺水平也不断提高，完全可以制造出较好的行星齿轮传动减速器。
根据负载情况进行一般的齿轮强度、几何尺寸的设计计算，然后要进行传动比条件、同心条件、装配条件、相邻条件的设计计算，由于采用的是多个行星轮传动，还必须进行均载机构及浮动量的设计计算。
行星齿轮传动根据基本够件的组成情况可分为:2K—H、3K、及K—H—V三种。若按各对齿轮的啮合方式，又可分为:NGW型、NN型、WW型、WGW型、NGWN型和N型等。我所设计的行星齿轮是2K—H行星传动NGW型。

减速器是一种动力传达机构，利用齿轮的速度转换器，将马达的回转数减速到所要的回转数，并得到较大转矩的机构。
减速器降速同时提高输出扭矩，扭矩输出比例按电机输出乘减速比，但要注意不能超出减速器额定扭矩。降速同时降低了负载的惯量，惯量的减少为减速比的平方。

一般的减速器有斜齿轮减速器(包括平行轴斜齿轮减速器、蜗轮减速器、锥齿轮减速器等等)、行星齿轮减速器、摆线针轮减速器、蜗轮蜗杆减速器、行星摩擦式机械无级变速机等等。按传动级数主要分为:单级、二级、多级;按传动件类型又可分为:齿轮、蜗杆、齿轮-蜗杆、蜗杆-齿轮等。
1) 蜗轮蜗杆减速器的主要特点是具有反向自锁功能，可以有较大的减速比，输入轴和输出轴不在同一轴线上，也不在 同一平面上。但是一般体积较大，传动效率不高，精度不高。
2) 谐波减速器的谐波 传动是利用柔性元件可控的弹性变形来传递运动和动力的，体积不大、精度很高，但缺点是 柔轮寿命有限、不耐冲击，刚性与金属件相比较差。输入转速不能太高。
3) 行星减 速器其优点是结构比较紧凑，回程间隙小、精度较高，使用寿命很长，额定输出扭矩可以做 的很大。

摘  要:本设计是应淀粉厂的要求而进行设计的，由于目前面筋的生产过程全部为手工作业，工作环境十分恶劣，然而面筋的市场需求量很大(由于其营养价值和市场地位高)，所以面筋的机械化操作显得尤为迫切。面筋机的设计分为三个部分:面筋机的坯片导出和切断装置的设计和卷绕装置的设计。本课题为螺旋管状面筋机总体及坯片导出装置设 计，着重设计面筋机的坯片导出及切断装置。由于面筋特有的粘弹性质，以及参照去年设计 的面筋机样机，在此重新提出的解决方案为:一定量的面筋通过螺旋丝杠的挤压从大料斗被 送至小料斗，中间通过切料刀具切断，以便控制单个面筋的重量。被切断的面筋通过导出口 导出，被送至卷绕装置卷绕。面筋由于要先切断后通过小料斗导出，所以采用凸轮机构来控 制比较方便。采用一大一小两个料斗是更利于面筋的导出成型。这样的设计符合工厂的实际 生产需要，满足食品生产的卫生要求，有很高的市场经济的价值。

The Design of The Overall and The Piece Educing Setting Unit of The Spiral Tubular Gluten Machine
Abstract :The design is requested by Louwang starch factory. The operation of the mechanization of the gluten is especially impendency because the production of the gluten is handiwork at present, the work circumstance is very abominable, and the gluten’s demanding is massive (because of the nutritional value and the market niche). The design of gluten molding machine divided into three parts: the piece educing setting unit, the cutting setting unit and the winding device unit. This project is the design of the overall and the piece educing setting unit of the spiral tubular Gluten machine. It mainly introduce the design the piece educing setting unit and the cutting setting unit because of its unique viscoelastic nature, and the reference to the last design of the gluten molding machine. The solution of the design of the gluten molding  machine: The certain amount of gluten is sent from the big hopper to the small hopper through the helical screw extrusion. The gluten is cut by the middle cutting tool materials. The weight of the single gluten is controled by the cutting tool materials. The gluten which is cut is educed by the export of gluten guidance .The device is sent to the winding device unit. Because the gluten should be cut before it is sent to the export of gluten guidance through the small hopper, the use of cam mechanism to control is more convenient. The  two hoper is more conducive to the gluten derived molding. The design accords with the practical production need of the factory and meets the sanitation demand of the food production .So the design of the gluten shaping machine has a high market economic value.
