ABSTRACT:
A rigid internal gear2of the wave gear device is composed by integrating a tooth-forming ring12formed with internal teeth, and a main gear ring11into a single body. The tooth-forming ring12is manufactured from a ferrous or copper material that has superior strength and abrasion resistance, while the main gear ring11is manufactured from a lightweight material, such as an aluminum alloy. The outer circumferential surface of the tooth-forming ring12is aluminized to form a dispersed aluminum coating15,before the tooth-forming ring12is cast within the main gear ring11so as to integrate the main gear ring11and the tooth-forming ring12.Both parts are reliably integrated so that a large amount of torque can be transmitted, whereby realizing a rigid internal gear that is lighter than conventional models.
