RESIN GEAR AND METHOD FOR MANUFACTURING RESIN GEAR

摘要

PROBLEM TO BE SOLVED: To provide a resin gear for improving durability by effectively receiving stress applied to a tooth surface of a gear by reinforced fibers, and sufficiently infiltrating resin between the reinforced fibers without making denseness/ roughness of the reinforced fibers in the resin gear for constituting a tooth part of the ring-shaped mold by using a ring-shaped reinforced fiber base material inconspicuous in a seam. SOLUTION: Belt-like felt 1 is formed into a cylindrical shape by lap winding, and a ring-shaped reinforced fiber base material 3 by folding up the cylindrical body 2 in a bellows shape is used. The belt-like felt 1 has the constitution by joining mutual reinforced fibers turning in the planar direction by reinforced fibers turning in the thickness direction. A tooth part of a gear is composed of a ring-shaped mold by impregnating such a reinforced fiber base material 3 with resin.
