| Axle system construction design is one of the most important part of mechanical system. It is very important in mechanical design curriculum too. It is weak in teaching because of containing many problems and needing practicing. Now students lack practicing experience, handling present problems ability, so, in order to make them improve these ability we do this development.Axle is one of the most important parts of machines. It provides bases forparts, which is assembled on it. It passes power and motions. The ability and working quality of a machine are mainly depended on axles. Once axle fails, serious problems may occur. So the design of axle is very important and different from the design of general machine parts. Axle design includes two contents: strength design and construction design. In order to assure the correct position of parts on axle and meet with the requirement of axle making and assembling it is necessary to design the shape and construction sizes of axle correctly, which is construction design. During actual designing, strength design affects construction design so it is absolutely necessary to consider the relationship between strength design and construction design.The essay is focused on the construction during my axle system design. Customers can use software to get familiar with the construction design and construction analysis of axle; construction and function of axle and other parts on axle; the fit way of parts on axle; the types, the adjustment, lubrication, and sealing way of bearings.The essay is studying the database and software system development of axle system by applying with database technology, the technology of featuring modeling, parametric drive technology and automatic assembly technology. The essay mainly contains the following:1. Based on the designing consideration, using Delphi7, develop the designer-to-computer exchanging design system, introduce the design procedure and the mean to realize.
