Abstract: A wave generator of a strain wave gearing has a plug, a wave generator bearing mounted to an outer peripheral surface of the plug, an input shaft protruding from the center of the plug to a first side running along a center axis, and a bearing arrangement on which a support bearing supporting the input shaft is arranged. Relative to an outer ring end surface of the wave generator bearing that faces the first side, a center-side plug end surface of a plug end surface facing the same direction is in a position withdrawn from the first side toward the opposite direction. The bearing arrangement is provided between the center-side plug end surface and the outer ring end surface encircling the input shaft. The input shaft can be fitted within the width dimension of the wave generator, and a strain wave gearing having a short axial length can be achieved.

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.
