RESIN GEAR AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a resin gear with improved high bonding strength of a ring-shaped molding body to a metallic bush, in the resin gear of which the gear part is formed out of a ring-shaped molding part using a ring-shaped reinforcing fiber base material with an inconspicuous seam. SOLUTION: The ring-shaped reinforcing base material 2 is used which is constituted by overlap-winding a band-shaped base material 1 knitted with flexibility to form a cylindrical shape and axially folding the cylindrical body in the form of a bellows shape. The gear part of the gear is formed out of the ring-shaped molded part where the ring-shaped reinforcing base material 2 is impregnated with resin.
