Abstract: A wave gear unit has an input shaft positioned along a center axis by first and second input bearings. A first unit end plate at the first-input-bearing side is a composite member in which a bearing housing member of an iron-based material is integrated with an end plate main body member of a lightweight material. A second unit end plate at the second-input-bearing side is integrated with a rigid internally toothed gear, and is a composite member in which a second member of a lightweight material is integrated with a first member of a lightweight material. The first member has an end plate main body portion of the second unit end plate and a gear main body portion of the rigid internally toothed gear, while the second member has a bearing housing portion of the second unit end plate and a teeth formation portion of the rigid internally toothed gear.

Abstract: In a wave gear device, the inner race and the boss are fixed together by a laser welded part formed along the entire periphery thereof. The laser welded part also functions as an oil seal for sealing the inner race and the boss. The boss and the inner race are fixed together in a manner that a required axial length is short, and that machining and assembling steps are reduced. Oil seal members are not required to seal the boss and the inner race.
