ABSTRACT:
A method for manufacturing a rigid internal gear of a wave gear device in which an internally toothed portion formed with internal teeth and a gear main body portion are joined integrally, the method including preforming an internal teeth-forming ring or disc for forming the internally toothed portion by using a first aluminum alloy powder; manufacturing a forging in which the internal teeth-forming ring or disc is placed in a forging die and is integrally formed on its outer side with the gear main body portion using a second aluminum alloy powder, the first aluminum alloy powder being harder and having higher abrasion resistance than the second aluminum alloy powder; and applying post-processing including cutting teeth to the forging.
