Abstract
The present disclosure provides a method for manufacturing a gear capable of processing a projection formed on a tooth tip by shot peening while reducing time for manufacturing the gear. A method for manufacturing a gear includes: a process of hardening, by performing shot peening in which shot particles are jetted onto a tooth surface 1a of a gear base material, the tooth surface while applying residual stress to the tooth surface; a process of softening, by at least heating a tooth tip of the gear base material having the hardened tooth surface, the tooth tip; and a process of rotationally driving the gear base material having the softened tooth tip by engaging it with another gear.
Claims3
A method for manufacturing a gear, the method comprising:
- a process of hardening, by performing shot peening in which shot particles are jetted onto a tooth surface of a gear base material, the tooth surface while applying residual stress to the tooth surface;
- a process of softening, by at least heating a tooth tip of the gear base material having the hardened tooth surface, the tooth tip;
- and
- a process of rotationally driving the gear base material having the softened tooth tip by engaging the gear base material having the softened tooth tip with another gear and pressing a projection formed on the tooth tip by the shot peening against a tooth surface of the other gear to deform the projection so that the projection conforms to the tooth surface of the other gear.
