3D Modeling of Five Speed Manual Transmission System for Teaching Aid Vehicles

Abstract

Additive manufacturing education is becoming to widespread adoption. Additive manufacturing is also the manufacturing technology. It is used by multiple industry subsectors, including motor vehicles, aerospace, machinery, electronics, and medical products. It can facilitate the customized production of strong light-weight 3D modeling. This paper describes 3D modeling of five speed transmission is designed and constructed by using AutoCAD software, 3D Mesh software, MakerBot 3D printer and digitizer. This 3D modeling of five speed transmission is good quality through lighter part, can demonstrate easily. The teacher can take 3D modeling of transmission and teach the operations of transmission in the classroom. It can produce the gears, fork, cover and synchronizer sleeves with different color. Many beautiful colors are interested to the students. So, it can use as teaching aids for the engineering students. In this transmission, five forward speed gears are helical type whereas reverse gears are spur type. Design consideration of spur gear and helical gears and shafts are included in this paper. In gear design, the number of teeth, face width, gear tooth features and pitch diameter are calculated. The shafts are designed according to the point of view of the strength.
