Abstract

PURPOSE:To improve resistance to wear of a gear and to improve bending strength, by a method wherein the material of the surface layer of the tooth part of a gear forms plastic, an inner layer is formed by a sintered metal, and the surface layer and the inner layer are integrally molded. CONSTITUTION:The material of a gear forms 2-layer structure, and mainly a surface layer 1 is assigned for resistance to wear. Since a gear is used in a grease lubricating state or in a non-lubricating state, the surface layer 1 may be formed by plastic. An inner layer 2 is assigned for bending strength, and forms structure having a tooth part and formed by a metal in order to improve the strength of a tooth shape. In order to solidify bonding of the surface layer 1 to plastic, the surface layer of a metal is formed in a porous state, and a sintered metal the density of which is regulatable is used. Thus, the surface layer 1 has high resistance to wear, high bending strength is held by the core part of the inner layer 2, and a gear life can be increased on the whole.
