【摘要】：二次包络环面蜗杆传动副比普通蜗杆副有更大的承载能力、更高的传动效率以及更长的使用寿命,并可以适用于普通蜗杆副能应用的各类场合,是普通蜗杆传动副的一种升级替换产品。然而,目前并未见二次包络环面蜗杆副替代普通蜗杆副,实现大规模生产应用,究其原因,是由于其制造成本居高不下。为了解决上述问题,推动二次包络环面蜗杆传动副的发展,论文选择了双锥面二次包络环面蜗杆副为对象进行了相关研究,并取得了具有应用价值的成果,主要体现在以下几个方面：1.建立了双锥面二次包络环面蜗杆副的多目标优化设计模型。该模型以三个对环面蜗杆副数学模型有直接影响的可变参数为优化变量；在考虑双线接触性能的基础上,以最小油膜厚度最厚及接触线分布范围最合理为优化目标；以避免环面蜗杆根切和边齿顶变尖为约束条件。通过一个实例的优化设计及计算对比分析,以及优化前后产品的性能测试实验,验证了该优化模型的有效性。该成果可以应用于双锥面二次包络环面蜗杆副产品的设计,为产品批量制造前的系列化设计提供理论基础。2.研制了适用于双锥面二次包络环面蜗杆副批量生产的关键制造装备。一台是应用于蜗杆齿面精磨的双锥面二次包络环面蜗杆数控磨床；还有一台是应用于环面蜗轮滚刀铲磨加工的环面蜗轮数控铲磨机床。使用上述装备进行了双锥面二次包络环面蜗杆减速器产品的制造,验证了装备的实用性。同时申请并获得了相关的发明专利的授权。该成果为为双锥面二次包络环面蜗杆副的批量生产提供了制造装备上的保障。3.对比普通圆柱蜗杆副蜗轮滚刀,分析了双锥面二次包络环面蜗轮滚刀铲磨的难点,推导了用于计算双锥面二次包络环面蜗轮滚刀后角的公式。进行了双锥面二次包络环面蜗轮滚刀的设计,并建立了滚刀的三维模型。建立了环面蜗轮滚刀基本蜗杆的轴截面模型,在此基础上提出了滚刀基本蜗杆加工误差检测及补偿的方法,并通过实验进行了验证。基于环面蜗轮滚刀数控铲磨机床,提出了双锥面二次包络环面蜗轮滚刀的后角铲磨方法,提高了加工的效率及精度,并通过检测验证了加工方法的有效性。该成果解决了限制双锥面二次包络环面蜗杆副批量生产的瓶颈问题——滚刀制作。
[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.
