【摘要】：二次包絡環(huán)面蝸桿傳動副比普通蝸桿副有更大的承載能力、更高的傳動效率以及更長的使用壽命,并可以適用于普通蝸桿副能應用的各類場合,是普通蝸桿傳動副的一種升級替換產(chǎn)品。然而,目前并未見二次包絡環(huán)面蝸桿副替代普通蝸桿副,實現(xiàn)大規(guī)模生產(chǎn)應用,究其原因,是由于其制造成本居高不下。為了解決上述問題,推動二次包絡環(huán)面蝸桿傳動副的發(fā)展,論文選擇了雙錐面二次包絡環(huán)面蝸桿副為對象進行了相關研究,并取得了具有應用價值的成果,主要體現(xiàn)在以下幾個方面：1.建立了雙錐面二次包絡環(huán)面蝸桿副的多目標優(yōu)化設計模型。該模型以三個對環(huán)面蝸桿副數(shù)學模型有直接影響的可變參數(shù)為優(yōu)化變量；在考慮雙線接觸性能的基礎上,以最小油膜厚度最厚及接觸線分布范圍最合理為優(yōu)化目標；以避免環(huán)面蝸桿根切和邊齒頂變尖為約束條件。通過一個實例的優(yōu)化設計及計算對比分析,以及優(yōu)化前后產(chǎn)品的性能測試實驗,驗證了該優(yōu)化模型的有效性。該成果可以應用于雙錐面二次包絡環(huán)面蝸桿副產(chǎn)品的設計,為產(chǎn)品批量制造前的系列化設計提供理論基礎。2.研制了適用于雙錐面二次包絡環(huán)面蝸桿副批量生產(chǎn)的關鍵制造裝備。一臺是應用于蝸桿齒面精磨的雙錐面二次包絡環(huán)面蝸桿數(shù)控磨床；還有一臺是應用于環(huán)面蝸輪滾刀鏟磨加工的環(huán)面蝸輪數(shù)控鏟磨機床。使用上述裝備進行了雙錐面二次包絡環(huán)面蝸桿減速器產(chǎn)品的制造,驗證了裝備的實用性。同時申請并獲得了相關的發(fā)明專利的授權。該成果為為雙錐面二次包絡環(huán)面蝸桿副的批量生產(chǎn)提供了制造裝備上的保障。3.對比普通圓柱蝸桿副蝸輪滾刀,分析了雙錐面二次包絡環(huán)面蝸輪滾刀鏟磨的難點,推導了用于計算雙錐面二次包絡環(huán)面蝸輪滾刀后角的公式。進行了雙錐面二次包絡環(huán)面蝸輪滾刀的設計,并建立了滾刀的三維模型。建立了環(huán)面蝸輪滾刀基本蝸桿的軸截面模型,在此基礎上提出了滾刀基本蝸桿加工誤差檢測及補償?shù)姆椒?并通過實驗進行了驗證�；诃h(huán)面蝸輪滾刀數(shù)控鏟磨機床,提出了雙錐面二次包絡環(huán)面蝸輪滾刀的后角鏟磨方法,提高了加工的效率及精度,并通過檢測驗證了加工方法的有效性。該成果解決了限制雙錐面二次包絡環(huán)面蝸桿副批量生產(chǎn)的瓶頸問題——滾刀制作。
[Abstract]:Two enveloping worm gearing transmission than the ordinary worm have greater carrying capacity, higher transmission efficiency and longer service life, and can be applied to ordinary worm gear can be used all kinds of occasions, is a pair of worm gearing to upgrade the replacement product. However, at present no two enveloping worm gear worm gear instead of the ordinary, to achieve large-scale production and application, the reason is because of its high manufacturing costs. In order to solve the above problems, to promote the two enveloping worm gearing transmission development, this paper selects two double cone enveloping worm gear as the object of research, and achieved with application value the results, mainly reflected in the following aspects: 1. the establishment of the two double cone enveloping worm gear of the multi-objective optimization model. The model takes three of worm gear pair model with straight The influence of variable parameters as optimization variables; considering the double contact performance, with the minimum oil film thickness and the thickness of the contact line distribution is the most reasonable as the optimization goal; to avoid undercutting worm and edge sharpening the top gear as constraint conditions. Through an example of optimization design and calculation comparison analysis and before and after optimization of product performance test, verify the validity of the optimization model. The results can be applied to two double cone enveloping worm gear products, to provide a theoretical basis for the design of a series of.2. before the batch manufacturing product development key for two double cone enveloping worm pair production manufacturing equipment. One is applied to the worm tooth surface grinding of the two double cone enveloping worm CNC grinder; and a worm wheel is used in CNC worm wheel hob grinding Grinding machine. The manufacture of two double cone enveloping worm reducer product to use the equipment, to verify the practicability of equipment. At the same time to apply for and obtain the relevant patent licensing. The results provide a guarantee on the.3. manufacturing equipment in comparison with ordinary cylindrical worm gear hob for double cone two double enveloping worm mass production, analyzed the difficulties of two double cone enveloping worm gear hob grinding, formulas for the calculation of two double cone enveloping worm gear hob angle. The formula of the double cone enveloping worm wheel hob two design, and set up the three-dimensional model of the hob was established. The shaft section model of worm wheel hob basic worm, method is proposed based on the detection and compensation of machining error of hob basic worm, which is validated by experiments. Based on enveloping worm hob CNC grinding machine shovel, put forward two double cone enveloping worm gear hob grinding method of shovel back angle, improve the efficiency and accuracy of processing, and effective processing method is verified by testing. The results to solve the bottleneck of the two double cone enveloping worm gear hob - batch production.
