FIBER-REINFORCED RESIN GEAR

摘要

PURPOSE:To provide a fiber-reinforced resin gear in which a strength of a toothed part and wear resistance of the vicinity of a pitch circle of an engaging surface are obtained while enhancing processability in the case of gear cutting. CONSTITUTION:A prepreg containing meta series aramid fiber and a prepreg containing carbon fiber are superposed, and wound in a rod state. Both ends of the rod state are matched in a doughnut state, molded and fixed in a ringlike material. Teeth are cut on an outer periphery of the material, and fibers are oriented in an annular ring state of a tree on an engaging surface 70 of a toothed part 7. A reinforced part 7a reinforced by aramid fiber is formed on an outermost periphery of the part 7, and a composite reinforced part 7b reinforced by aramid fiber and carbon fiber is formed at its central side. The part 7b is disposed at a position corresponding to a pitch circle 73.
