II. Historical traceability: from da Vinci's manuscripts to modern industry<\/strong><\/p>\n\n\n\n

The mechanical design idea of ring surface envelope can be traced back to the Renaissance. The worm gears depicted in Leonardo da Vinci's manuscripts do not directly present the concept of \"ring surface envelope\", but they are useful for the design ofmultitooth gearing<\/strong>The exploration with the curved surface drive has shown its beginnings. Because the structure is special, subject to the industrial production technology in those years, has not been realized. Until the modern industry, this theory was standardized in the 1990s as a planar secondary envelope ring face worm gear transmission, which forms a high-precision tooth contact through the envelope machining of the plane mother face and the relative motion. Based on this, Tao Shi's team combined miniaturized manufacturing processes to design theExclusive tooth shape<\/strong>, taking this classic structure to new heights.<\/p>\n\n\n
