Abstract

The purpose of this research is to study the design of optimised gear based on the existing gear in the online market. There are many types of gear that exist, made from different materials. Each type of gear has unique properties such as bending stress, strength, wear, and so on. The material has been used in appropriate conditions as needed. For this research project, the simplest gear has been chosen, which is spur gear from the online store. One of the gear models has been chosen and drawn in CATIA V5R21, which is one of the CAD software. Next, the model of the gear has been analysed and drawn in CATIA V5R21, followed by the dimension that has been given in the catalogue for the customer. Then, in CATIA V5R21 too, simple simulations have been analysed in the software for analysing static analysis and dynamic analysis. From the drawing, the replica of the gear is produced the same as the real one in the online market using 3D printing, which is an SLS machine. The gear replica is made from PA12 NYLON material, while the original gear that has been purchased is made from brass material. Both of these pieces of equipment are used to investigate the wear of each piece of equipment.The study used the disc experiment method. The result of the experiment and the data recorded are presented in this thesis. The result of the experiment was to differentiate between the two types of gear.
