【摘要】：Hy-Vo齒形鏈是齒形鏈產(chǎn)品中的一種重要類型，具有高速性能好，承載能力強，耐磨性好等優(yōu)點。由于Hy-Vo齒形鏈的“變節(jié)距”在嚙合過程中能夠顯著減少傳動中的多邊形效應、降低傳動噪聲，因而近年來廣泛應用于汽車變速箱、分動箱、汽輪機工業(yè)泵等高速傳動中。齒形鏈按照嚙合機制的不同主要分為外嚙合機制Hy-Vo齒形鏈、內-外復合嚙合機制Hy-Vo齒形鏈和外嚙合+內-外復合嚙合機制Hy-Vo齒形鏈。 本論文是在國家自然科學基金項目“基于多元變異的新型Hy-Vo齒形鏈嚙合設計理論（50975117）”和“基于復雜約束邊界條件下的多軸高速齒形鏈系統(tǒng)嚙合設計理論”（51275207）以及國家高技術研究發(fā)展計劃項目（863）“基于復雜多元變異的Hy-Vo齒形鏈數(shù)字化方法研究及平臺開發(fā)（2009AA04Z109）”的資助和支持下，對Hy-Vo齒形鏈的嚙合機理進行了深入的研究，并針對Hy-Vo齒形鏈的多元變異特性進行了通用設計方法的研究，同時研究了其嚙合設計體系、動力學仿真技術、導板設計方法以及疲勞試驗方法。 論文在分析比較Hy-Vo齒形鏈分類及不同嚙合機制的基礎上，針對Hy-Vo齒形鏈嚙合機制變異、形狀變異、參數(shù)變異等變異特性進行了系統(tǒng)的研究，基于學科與行業(yè)技術發(fā)展趨勢，首次提出多元變異的概念，并指出以嚙合機制與傳動特性變異為主體的多元變異過程，就是Hy-Vo齒形鏈產(chǎn)品系列創(chuàng)新升級的過程，也是行業(yè)需求和技術進步的必然趨勢。 論文在分析研究鏈輪滾刀與鏈輪滾切原理的基礎上，根據(jù)Hy-Vo齒形鏈與鏈輪的嚙合原理，首次構建了基于多元變異的Hy-Vo齒形鏈嚙合設計體系，并指出將Hy-Vo齒形鏈工作鏈板齒形視為滾刀法向齒形，是建立Hy-Vo齒形鏈-鏈輪-刀具齒條的嚙合設計體系的基本條件。通過分析Hy-Vo齒形鏈與鏈輪的嚙合原理，首次提出Hy-Vo齒形鏈相鄰工作鏈板的基準圓圓心連線延長線的交點位于齒槽對稱中心線上是實現(xiàn)Hy-Vo齒形鏈正確嚙合定位的必要條件，這與套筒滾子鏈傳動以及齒輪傳動的正確嚙合條件是根本不同的。 論文以同一規(guī)格、同一節(jié)距的兩種變異HV3型非圓形基準孔的內-外復合嚙合Hy-Vo齒形鏈為例，通過設計計算與分析，并提出在滿足Hy-Vo齒形鏈-鏈輪-刀具齒條三者正確嚙合的條件下，可以通過多元變異手段，設計出參數(shù)不同的一族新型傳動，以滿足眾多主機不同的“個性化”需求。同時，通過兩種鏈條系統(tǒng)的平穩(wěn)傳動試驗結果表明，基于多元變異的Hy-Vo齒形鏈設計方法是科學的，切實可行的。并提出多元變異設計方法是實現(xiàn)Hy-Vo齒形鏈產(chǎn)品創(chuàng)新升級和知識產(chǎn)權保護的重要手段。 論文在參考精密滾子鏈疲勞可靠性試驗方法的基礎上，首次對Hy-Vo齒形鏈疲勞試驗方法進行了研究，并提出了為節(jié)約試驗時間，可提高一個載荷系數(shù)等級獲得24F-N方法試驗數(shù)據(jù)；提高試驗載荷后的疲勞壽命曲線相比未提高試驗載荷的曲線要保守一些。通過對比研究14F-N方法和24F-N方法，提出粗估鏈條壽命時，可采用14F-N方法并提高一個載荷系數(shù)；R=50%的R-F-N曲線可以由14F-N方法獲得；14F-N方法和24F-N方法所得到的疲勞壽命曲線形式基本一致。論文同時對新型Hy-Vo齒形鏈進行了疲勞試驗研究，結果表明鏈條在滿足抗拉強度要求的情況下，不一定能夠滿足疲勞性能要求，證明研究鏈條疲勞壽命的重要性。 論文在分析齒形鏈導板的作用及導板對Hy-Vo齒形鏈裝配及受力影響的基礎上，通過對Hy-Vo齒形鏈導板的研究，首次提出了Hy-Vo齒形鏈導板的設計方法，并進行了有限元分析和試驗研究。研究發(fā)現(xiàn)，在不影響導板抗拉強度的條件下，，蝴蝶狀導板腰部上端圓弧半徑RG越大越好；在滿足導板抗拉強度的條件下，盡量減小HG的高度，如果中間圓弧最低點高于銷軸中心連線，應適當加大兩者之間的距離。研究結果表明Hy-Vo齒形鏈可以通過設計合理的蝴蝶狀導板在拉伸過程中的變形來補償間隙。同時研究成果應用于工程實際，給相關行業(yè)帶來了良好的經(jīng)濟效益。 論文在分析多體動力學接觸搜索算法的理論基礎上，采用Recurdyn動力學仿真軟件，針對多元變異設計方法設計出的三種不同鏈板型式組合的新型Hy-Vo齒形鏈進行了多鏈節(jié)的運動學和動力學仿真分析。仿真結果表明，采用多元變異設計方法獲得的Hy-Vo齒形鏈，通過不同嚙合機制鏈板的有序組合，可以根據(jù)用戶的個性化需求派生出多種Hy-Vo齒形鏈新產(chǎn)品。通過分析研究三種Hy-Vo齒形鏈的多邊形效應變化規(guī)律發(fā)現(xiàn)，在一定范圍內，新型Hy-Vo齒形鏈中內-外復合鏈板數(shù)越多，多邊形效應越小，且有序排列的新型Hy-Vo齒形鏈綜合性能要優(yōu)于純外嚙合機制Hy-Vo齒形鏈和純內-外復合嚙合機制Hy-Vo齒形鏈。通過分析研究新型Hy-Vo齒形鏈的動態(tài)接觸響應發(fā)現(xiàn)，同一新型Hy-Vo齒形鏈在同一時間和同一水平位置時，同一鏈板所對應的兩對銷軸的接觸力并不相同，因此不能簡單的通過分析一個鏈節(jié)的受力，判斷其它鏈節(jié)的受力情況，為Hy-Vo齒形鏈動力學研究提供了重要的理論指導。
[Abstract]:Hy-Vo tooth chain is an important type of tooth chain products. It has the advantages of high speed performance, strong bearing capacity and good wear resistance. Because the "pitch" of the Hy-Vo tooth chain can reduce the polygon effect in the transmission and reduce the transmission noise in the meshing process, so it has been widely used in automobile gearbox, shunt box and steam in recent years. In high speed transmission, such as turbine industrial pump, the tooth chain is divided into Hy-Vo tooth chain of outer meshing mechanism according to the difference of meshing mechanism, internal and external meshing mechanism Hy-Vo tooth chain and outer meshing + inner outer composite meshing mechanism Hy-Vo tooth chain.
This paper is based on the National Natural Science Foundation Project "new Hy-Vo tooth chain meshing design theory based on multivariate variation (50975117)" and "multi axis high-speed tooth chain system meshing design theory based on complex constrained boundary conditions" (51275207) and national high-tech research and development project (863) "based on complex multivariate variation. With the support and support of the digital method of Hy-Vo tooth chain and the support of platform development (2009AA04Z109), the meshing mechanism of the Hy-Vo tooth chain is deeply studied. The general design method of the multiple variation characteristics of the Hy-Vo tooth chain is studied. At the same time, the meshing design system, the dynamic simulation technology and the guide plate setting are studied. Method and fatigue test method.
Based on the analysis and comparison of the Hy-Vo tooth chain classification and the different meshing mechanism, this paper systematically studies the variation characteristics of Hy-Vo tooth chain meshing mechanism variation, shape variation, parameter variation and so on. Based on the development trend of discipline and industry technology, the concept of multiple variation is proposed for the first time, and the variation of meshing mechanism and transmission characteristics is pointed out. The process of multivariate variation is the process of innovation and upgrading of Hy-Vo toothed chain products, and it is also an inevitable trend of industry demand and technological progress.
On the basis of analyzing the principle of sprocket hob and sprocket rolling, according to the meshing principle of Hy-Vo tooth chain and sprocket, the Hy-Vo tooth chain meshing design system based on multiple variation is constructed for the first time, and it is pointed out that the tooth shape of Hy-Vo tooth chain work chain plate is regarded as the normal tooth shape of the hob, and it is the meshing of the Hy-Vo tooth chain chain wheel tool rack. By analyzing the basic conditions of the design system, by analyzing the meshing principle of the Hy-Vo tooth chain and the sprocket, it is the first time that the intersection point of the reference circular line extension line of the adjacent working chain plate of the Hy-Vo tooth chain is located on the symmetric center line of the alveolus, which is the necessary piece to realize the correct meshing and positioning of the Hy-Vo tooth chain, which is with the sleeve roller chain transmission and the gear transmission. The correct meshing conditions are fundamentally different.
In this paper, an example of the internal and external meshing Hy-Vo tooth chain of two variant HV3 non circular datum holes with the same specification and the same pitch is taken as an example. Through the design calculation and analysis, it is proposed that under the conditions of satisfying the correct meshing of the three parties of the Hy-Vo tooth chain chain wheel tool rack, a new type of new transmission with different parameters can be designed. In order to meet the different "personalized" needs of many hosts, the test results of the smooth transmission of two chain systems show that the design method of Hy-Vo tooth chain based on multivariate variation is scientific and feasible. It is proposed that the multiple variant design method is to realize the innovation and upgrade of Hy-Vo tooth chain products and the protection of intellectual property rights. Take the means.
On the basis of the fatigue reliability test method of precision roller chain, the paper studies the Hy-Vo tooth chain fatigue test method for the first time, and puts forward that the test data of 24F-N method can be obtained by increasing a load coefficient grade for saving test time, and the fatigue life curve after the test load is raised, compared with that of not increasing the test load. The curve should be conservative. By comparing the 14F-N method and the 24F-N method, the 14F-N method can be used and a load coefficient can be improved when the chain life of the chain is estimated. The R-F-N curve of the R=50% can be obtained by the 14F-N method, and the fatigue life Qu Xianxing formula obtained by the 14F-N method and 24F-N method is basically the same. The paper also has a new Hy-Vo tooth shape at the same time. The chain has been tested by fatigue test. The results show that the chain can not meet the requirements of fatigue performance and proves the importance of studying the fatigue life of chain when the chain satisfies the requirement of tensile strength.
On the basis of the analysis of the role of the tooth chain guide plate and the influence of the guide plate on the assembly and the force of the Hy-Vo tooth chain, the design method of the Hy-Vo tooth chain guide plate is first proposed by the study of the Hy-Vo tooth chain guide plate, and the finite element analysis and experimental study are carried out. The study finds that the butterfly shape is not affected by the tensile strength of the guide plate. The larger the radius RG of the upper end of the guide plate is, the better the better, and the height of the HG is reduced as much as possible to meet the tensile strength of the guide plate. If the middle arc lowest point is higher than the central line of the pin axis, the distance between the two can be appropriately increased. The results show that the Hy-Vo tooth chain can be changed by setting a reasonable butterfly guide plate during the stretching process. The research results are applied to engineering practice, and bring good economic benefits to related industries.
On the basis of analyzing the theory of multi-body dynamic contact search algorithm, the paper uses Recurdyn dynamic simulation software to analyze the kinematic and dynamic simulation of the multiple chain joints of three different chain plate types designed by multiple variant design methods. The simulation results show that the multiple variant design side is used. The Hy-Vo tooth chain obtained by the method, through the orderly combination of different meshing mechanism, can derive a variety of new products of Hy-Vo tooth chain according to the personalized needs of the users. Through the analysis and study of the change rule of the polygon effect of the three Hy-Vo toothed chains, the number of internal and external composite chain plates in the new type Hy-Vo tooth chain is more, and the more the number of inner and outer composite chain plates in the new type of tooth chain is found. The smaller the edge shape effect is, the comprehensive performance of the new Hy-Vo tooth chain is better than that of the pure outer meshing mechanism Hy-Vo tooth chain and the pure inner outer composite meshing mechanism Hy-Vo tooth chain. The contact force of the two pairs of pin axes is different, so we can not simply analyze the force of a chain and determine the stress of other links, which provides important theoretical guidance for the study of the dynamics of Hy-Vo tooth chain.
