简介：基于Solidworks平台、UG软件提出两种斜齿轮三维造型通用设计方法.利用Solidworks软件的相关功能和UG的表达式功能生成斜齿轮的端面和法面轮廓线,最终实现对斜齿轮的计算机辅助三维实体造型;另外一种方法是利用渐开线的参数方程式并通过Autolisp进行编程,绘出端面齿廓曲线及螺旋线,用AutoCAD的"边界命令"构造斜齿轮的轮齿表面模型.

简介：直齿圆柱齿轮在PRO/E环境下造型方法复杂、工作量大。齿轮有多个参数,其中任何一个参数改变都需要对齿轮进行重新设计,耗时、费力。针对这种情况,本研究从渐开线的形成原理、决定齿轮大小、轮齿大小及形状的齿轮参数：齿数z、模数m、压力角α和齿宽B出发,在对齿轮造型的过程中逐步建立起渐开线产生的方程、齿顶圆、分度圆、齿根圆、基圆与齿数z、模数m、压力角α的关系,最后,只需在交互界面中输入齿轮参数即可获得需要的直齿圆柱齿轮。

简介：通过MDT三维工具集方便地实现了直齿轮的造型,重点说明了用基于特征造型的方法在MDT环境下实现斜齿轮造型的详细过程,并用MDT的有限元分析功能对齿轮的受力状况进行了分析.整个过程在MDT的集成环境下完成,对齿轮的工程设计具有较高的实用价值.

简介：说起来，这是个要命的三月天早晨：天空像块脏兮兮的旧抹布似的，有点灰黄色。从厨房的小窗户往下看，能看到一条同样像旧抹布、宽两米的水泥路，在它的边上是泛着黄叶的一溜矮冬青，看上去蔫巴巴的。往里是一片不长草的空地，这就是我楼下的走道。在峄阳县还有很多这样的街道，这样的小区，甚至一样蔫巴巴的矮冬青。

简介：我喜欢玩磁铁,对磁铁之间不接触就能够相互吸引或排斥的特点非常感兴趣。有一天,我在家安装四驱车齿轮时,突然产生一个想法:如用磁铁制作齿轮,那么不用接触就能传递动力,还具有摩擦小、不用润滑油、安装方便等诸多优
