A plastic gear has the advantages that it is light and can be used without any lubricant, and the disadvantages that its strength is low and that it has a large environmental impact. Therefore, the development of a new gear that maintains the advantages while negating the disadvantages has been proposed. The development of sustainable and reproducible natural materials is especially desired in order to address environmental problems. In this study, a method was therefore devised to extract high quality and highly precise bamboo fibers using a machining center. The hot press method was then used to produce a spur gear, which is a machine element with a complicated shape. Therefore, the present paper describes characteristics of the bamboo fiber gears investigated in some experiments. The results of a strength test showed that the bamboo fiber gear can be used as an alternative to the Mc nylon gear. The results of a meshing test showed that the teeth of a bamboo fiber gear underwent transformation because of the meshing load. In addition, we calculated travel value of meshing point by teeth deformation and compared experimental value of travel value with calculated value. Results show that the experimental deformation value is greater than the calculated value.
