【摘要】：CHC型少齒差減速器是一種新型齒輪傳動裝置,具有傳動比大、承載能力大、結(jié)構(gòu)緊湊、質(zhì)量輕、傳動效率高等諸多特點,可廣泛應用于石油、化工、起重運輸、建筑機械、港口船舶等各大工業(yè)領域。 CHC型少齒差減速器設計計算目前尚無國家標準。由于缺乏可靠的設計計算依據(jù),致使少齒差傳動相關零件參數(shù)選擇不合理,存在功率富裕、關鍵零件易失效等問題。另外,CHC型少齒差減速器為系列化產(chǎn)品,不同的產(chǎn)品規(guī)格在結(jié)構(gòu)上相似度較高,其設計存在重復性。針對這些問題,本文的主要目的是建立合理的少齒差傳動力學模型并進行相關的受力分析。在此基礎上提出少齒差傳動設計計算方法,合理運用現(xiàn)有的開發(fā)技術(shù)實現(xiàn)零件圖和裝配圖自動繪制,開發(fā)CHC型少齒差減速器CAD系統(tǒng),滿足產(chǎn)品系列化的要求。 在建立少齒差傳動力學模型基礎上,以少齒差傳動及關鍵零件的設計為例闡述采用VB編程開發(fā)CAD設計計算模塊,運用計算機輔助設計方法將各個設計過程程序化。運用VB自帶的數(shù)據(jù)庫的操作建立零件信息庫并保存設計結(jié)果,利用VB的文本文件的讀寫操作生成詳細的設計計算說明書。參數(shù)化繪圖系統(tǒng)運用VB編程采用ActiveX技術(shù)從外部操作AutoCAD的系統(tǒng)對象實現(xiàn)參數(shù)化繪圖,在利用開發(fā)的底層函數(shù)下,讀取零件信息庫中參數(shù)實行零件圖的自動化繪制,并結(jié)合ObjectDBX技術(shù)和對象的擴展詞典下實現(xiàn)裝配圖的自動繪制。通過零件信息庫從設計計算部分到參數(shù)化繪圖部分傳遞設計數(shù)據(jù)信息,按照文件執(zhí)行順序調(diào)用程序接口將各部分有效連接起來,最終實現(xiàn)設計計算和參數(shù)化繪圖一體化。
[Abstract]:CHC reducer with small tooth difference is a new type gear transmission device, which has many characteristics, such as high transmission ratio, large bearing capacity, compact structure, light weight, high transmission efficiency and so on. It can be widely used in petroleum, chemical industry, hoisting and transportation, construction machinery, etc. Port ships and other major industrial areas. At present, there is no national standard for the design and calculation of CHC reducer with small tooth difference. Due to the lack of reliable basis for design and calculation, the parameter selection of the parts related to the transmission with less tooth difference is unreasonable and the power is rich. In addition, CHC type reducer with less teeth difference is a series of products. Different product specifications have high structural similarity, and their design is repeatable. The main purpose of this paper is to establish a reasonable dynamic model of small tooth difference transmission and to carry on the related force analysis. On this basis, the design and calculation method of small tooth difference transmission is put forward, and the automatic drawing of parts drawing and assembly drawing is realized by reasonable use of existing development technology. The CAD system of CHC type low tooth differential reducer is developed to meet the requirements of product serialization. On the basis of establishing the dynamic model of small tooth difference transmission, taking the design of small tooth difference transmission and key parts as an example, the design and calculation module of CAD is developed by VB programming. Each design process is programmed by using the method of computer aided design. The part information database is established by the operation of the database provided by VB and the design result is saved. The parameterized drawing system uses VB programming technology to realize parameterized drawing from the system object of external operation of AutoCAD by using VB programming technology, under the use of the bottom function of development, the parametric drawing system uses VB text file reading and writing operation to generate detailed design and calculation instructions, and the parametric drawing system realizes parameterized drawing by using VB programming technology. Read the parameters in the part information database and carry out the automatic drawing of the part drawing. The automatic drawing of assembly drawing is realized under the ObjectDBX technology and the extended dictionary of object, and the design data information is transferred from the design calculation part to the parametric drawing part through the part information base. According to the file execution order, the program interface is called to connect each part effectively, and finally the integration of design calculation and parameterized drawing is realized.
