Through the worm reducer reducer of simple to understand learning design attempts to design enhanced by emotional cognitive and socio-cognitive, and further consolidate their theoretical knowledge and improve the comprehensive use of knowledge to problem solving problems in order to combine theory and practice, and learning experience for future work. Mechanical design learn how to learn to use a variety of tools such as CAD software UG software visual presentation on the plans, mechanical drives in constant use in the process be different degrees of wear, so the machinery and to maintenance and repair, extend its life, more efficient operation, improve productivity, reduce production costs, to maximize use. Worm reducer is to reduce the number of motor rotation to the number of rotation, and to get a larger torque structure is currently used to transfer power and movement of the body, a wide range of applications. In this paper, first of all, through the calculation of the speed and power of the motor, and then combined with the look-up table to select the appropriate motor. Then for different number of teeth and the modulus of cutting the amount of calculation, and select the optimal parameters. Through the reducer is simple to understand try to design enhance the perceptual cognition and to society's ability to adapt to, and further consolidate the theoretical knowledge of the lead, in order to theory and practice combine to together for the future work and a better learning experience.
