Abstract
This issue demands according to the given parameters of the first to design a worm lift Worm Drive institutions as a typical drive mechanism has been widely used. Design principle is the motor driven worm rotation, the use of worm gear transmission, so that worm wheel rotation, an inner trapezoidal thread worm, and screw co-rotating lead screw worm axial movement to do. Against the worm, first I need to determine the transmission ratio, calculated with the formula worm, according to various values, and its strength, stiffness etc. Check. For the screw, according to increase in speed, worm gear speed, calculate the pitch, nominal diameter. Finally the design of their simulation, using PROE powerful 3D modeling capabilities to achieve all of its modules are all related. This means that in the product development process of a Department modifications, can be extended to the entire design, while automatically updating all engineering documentation, including assembly, design drawings, and manufacturing data.
