摘　　要：目前太阳能追光系统普遍存在精度差、效率低等问题,主要原因在于环面蜗杆传动副为非正确共轭传动形式。针对现行太阳能追光系统中环面蜗杆副的非正确共轭传动形式,基于微分几何及空间啮合理论,推导了渐开面包络环面蜗杆齿面的精确数学模型,根据数学模型建立了蜗杆齿面的精确三维实体模型,并通过图形学显示了其正确啮合区;在DMG车铣复合加工中心加工渐开面包络环面蜗杆齿面,并进行了接触斑点对比试验,结果表明,环面蜗杆数学模型及三维实体模型正确,加工方法可行。At present, the problems of the poor accuracy and low efficiency etc exist in the solar tracking system, one of the main reasons is that the hourglass worm drive pair is not the right conjugating transmission form. Aiming at the wrong transmission form of the hourglass worm drive in the solar tracking system, based on the differential geometry and the space meshing theory, the accurately mathematical model of involute envelo- ping hourglass worm is deduced. The precise 3 D model of the hourglass worm tooth surface is established, and the contact areas are shown based on the graphics. The involute enveloping hourglass worm is manufactured in the DMG turning and milling machining center, and the contact pattern comparison test is carried out. The re- sults show that the mathematical model and the 3D model are correct, as well as the manufacture method is fea- sible.
