【摘要】：作为机械传动的主要传动形式,齿轮传动已经普遍应用于机械工业中,是衡量工业技术水平发展的重要指标。齿轮强度计算主要包括：接触强度、弯曲强度和胶合强度。为防止齿面疲劳点蚀,需要进行接触强度的计算；防止齿根疲劳折断,要进行弯曲强度的计算；防止齿面胶合,需要进行胶合计算。齿根折断和齿面疲劳点蚀都有寿命期限,超载后会降低寿命,一般不会立即发生破坏,可以通过同循环次数相关的疲劳极限应力加以控制。但是齿面胶合失效则不然,齿面胶合破坏的出现与时间无关,只要在短时间的超载、温升过高或者润滑不当的情况下,胶合就可能发生。由于齿面胶合失效形式是突发性的,并且不易防范和察觉,胶合失效具有更大的危险性。因此,建立一个合适的齿轮抗胶合承载能力计算方法是至关重要的,对创建一个完善的齿轮强度系统设计也是尤为重要的。由于齿轮强度系统设计过程相当复杂,需要查阅大量资料,并且还要进行反复的计算和校核。因此,利用计算机技术进行齿轮设计,是一种势不可挡的趋势。本课题主要的研究工作包括：根据闪温法原理和齿轮传动极压润滑条件下的摩擦因数,依据工业闭式齿轮润滑油选用方法的标准和FZG标准,推导了圆柱齿轮抗胶合承载能力接触应力的计算方法；依据齿轮强度计算方法,在Visual C++集成环境下,采用MFC框架技术,开发齿轮的可视化设计软件；对于设计过程中所涉及的图、表,分别采用了MATLAB与VC++混合编程技术与ADO数据库技术的处理方法,实现了自动化查询与调用图、表中的有关数据。
[Abstract]:As the main forms of mechanical drive, gear drive has been widely used in machinery industry, is an important indicator to measure the level of industrial technology development. The gear strength calculation including contact strength, bending strength and bonding strength. In order to prevent tooth surface fatigue pitting, we need to compute the contact strength; prevent tooth root fatigue fracture, calculation bending strength; prevent tooth bonding, need for bonding calculation. The tooth root fracture and tooth surface pitting are life, overload will reduce the life, generally not immediately destroyed, but by the same number of cycles of fatigue limit stress related to control. But the tooth face scuffing or tooth surface the emergence of scuffing failure has nothing to do with time, as long as the short time overload, high temperature or improper lubrication under the condition of bonding may occur. Because the tooth face scuffing The form is unexpected, and it is not easy to prevent and detect. The failure of bonding is more dangerous. Therefore, it is very important to establish a suitable calculation method for the gear anti gluing capacity. It is also very important for creating a perfect gear strength system design.
Because the design process of gear strength system is quite complex, we need to consult a lot of data and carry out repeated computation and verification. Therefore, it is an irresistible trend to design gear with computer technology.
The main work of this research include: according to the principle of gear transmission and flash temperature extreme pressure coefficient of friction lubrication conditions, on the basis of industrial closed gear oil selection method and FZG standard, deduces the calculation method of load-carrying capacity of contact stress of cylindrical gears; calculation method based on the gear strength in Visual C++ the integrated environment, using the MFC framework technology, visualization software design of gear; involved in the design process of the graph, table, the processing method of MATLAB and VC++ mixed programming technology and ADO database technology, automatic query and call graph is realized, the data in the table.
