摘要：蜗杆传动是最重要的齿轮传动之一，它由蜗杆和蜗轮组成，主要用于传递交错轴之间的回转运动和动力，通常两轴交错角为90°。传动中一般蜗杆是主动件，蜗轮是从动件。由于蜗杆传动具有传动比大、结构紧凑、传动平稳和噪声较小等优点，广泛应用于各种机器和仪器中。但是蜗轮蜗杆的齿面属于复杂造型，利用Pro/E强大的参数化设计等功能可以保证齿形的精确性。同时通过机构的运动仿真，动态观看运动仿真的啮齿和运动情况，测试机构的有关运动性能的参数，有利于机构优化和提高设计效率。

Abstract the worm drive is one of the most important gear transmission, It is made up of worm and worm gear，Mainly used for transfer between crisscross axis rotary motion and power, Usually two axial stagger Angle is 90 °. General worm is active in transmission, worm gear is a follower. Because of worm drive with large transmission ratio, compact structure, smooth transmission and less noise, etc, are widely used in various kinds of machines and equipment. But the worm and worm wheel tooth surface belongs to complex modeling, using Pro/E is a powerful function such as parametric design can guarantee accuracy of tooth profile. At the same time, through the mechanism motion simulation, dynamic watch movement simulation of rodents and movement, on sports performance parameters of the test facility, to optimize and improve the design efficiency.
