Abstract
In order to obtain the high surface durability of power transmission gears and to promote environmental protection, the tooth surface-finishing method using a plastic material was developed. In this paper, the influence of machining condition on tooth surface texture of case-carburized gears was studied. First, the various plastic materials could be obtained by mixing the white petrolatum with the volcanic-ashes in different particle sizes Secondly, the tooth surface of case-carburized gear was finished by use of a plastic material. Thirdly, the tooth surface was investigated by using a scanning electron microscopy and a surface texture measuring instrument. From these experiments, the following results are obtained. By applying the designed tooth surface-finishing method in the case-carburized gear tooth, the randomly-rough surface after heat treatment process almost become smooth. In the case of finished tooth surface, it is found that the values of three dimensional roughness parameters decrease with the increase of finishing distance and particle size of the volcanic-ashes.
