【摘要】 机械传动需要满足高速、重载、低噪声、高寿命等要求。齿轮传动目前仍是机械传动的主要形式，齿轮加工的质量直接影响着机械传动的质量。目前，硬齿面和整体淬火调质硬度在350HB左右的硬齿面几乎完全取代了硬度低于300HB的软齿面齿轮。研究高精度、高效率的硬齿面齿轮加工方法是机械制造业的主要任务之一。研究以珩代磨的硬齿面齿轮加工方法和珩齿机理具有重要的现实意义。本论文对珩齿机理进行了研究。 作为齿轮刀具的珩齿刀设计复杂。一般需要许多公式反复迭代计算，计算后要得到加工检验的图纸，还需要另外绘制。可采用计算机辅助设计提高设计速度，减少繁琐的公式计算。单纯采用某种语言虽可完成计算部分，但在绘制图形方面很困难。本论文采用AutoCAD和微软的基本类库MFC，完成计算和绘图功能。其主要利用了AutoCAD的通用绘图平台和C++类的继承性。三维实体模型能够直观反映出物体的特征，对于一些工程分析如有限元分析，数控加工等具有实际意义。本论文也对珩太原理工大学研究生论文齿刀三维实体模型进行了研究。 晰齿刀在制造工艺方面主要问题是作为切削刃的超硬材料CBN与复合镀层的结合力和等高性问题。目前，国内外解此类问题主要采用的工艺方法是电镀法。有专家也在力图用高温激光钎焊法解决此类工艺问题。本论文采用电镀法增强结合力，主要是合理的选择电镀工艺参数和高温热扩散使复合镀层与超硬材料CBN由机械结合达到冶金结合。电镀工艺参数主要包括电流密度、温度、PH值、搅拌、阴阳极和换向电流等因素，其中影响最大的是电流密度。经过大量实验，本论文得到了合理的工艺参数，达到了增强结合力的目的。更多还原

【Abstract】 Mechanical transmission need satisfy the requirement of high speed, heavy duty, low noise and longevity of service. Now, gear drive is still the major form of mechanical transmission .The quality of gear machined directly affects the quality of mechanical transmission. Now, the hard teeth profile and the around 350 HB hard teeth profile of overall quench and thermal refining have nearly replaced the soft teeth profile which is lower than 300 HB. It is one of the major tasks to study on the machining method of hard teeth profile gear with high efficiency and high precision for mechanical manufacturing industry .The study on the method of machining hard teeth profile gear of honing instead of grinding and honing mechanism has the meaning of important reality. Thispaper introduces design principle of honing.It is complex in the design of gear cutting tool such as honer. Normally, it need a lot of formula iteration calculations. It need additionally draw it after a lot of iteration calculations if we want to get drawing used in machining. It can raise design speed and reduce fussy formula calculation with CAD. It can only complete calculation with certain kind of programming language. To achieve the functions of calculation and drawing in the presence of the Microsoft Foundation Class and AutoCAD. This paper make use of the inheritance attribute of C plus and plus class and universal drawing platform of AutoCAD. Three-dimensional substance model can directly reflect the feature of object. It has actual meaning for some project analysis such as finite element analysis, numerical control processing etc. This paper also studies on three-dimensional solid model of honer.The major problem of honer in manufacturing process lies in binding force and equal height of super hard material CBN. Now, the major technology was adopted is electroplate law in domestic and foreign country. Some experts also attempt to solve the technology by the high temperature braze welding with the laser.This paper strengthens cohesion with electroplate law.It makes cohesion of super hard material and composite deposite reach metallurgical combination from mechanical combination by choosing reasonable electroplating technological parameter and thermal diffusion. Electroplating technological parameter includes factors of ampere density, temperature, PH value, stir, negative and positive pole. The maximum influencing factor is ampere density. Via plenty of experiments, this paper has gotten reasonable technology parameter and reached the purpose of strengthening cohesion.更多还原
