Abstract: A flat strain wave gearing (1) has a mechanism for preventing a flexible externally toothed gear (4) from moving in the direction of the device center axis (1a) with respect to a rigid internally toothed gears (2, 3). The mechanism has an inner-peripheral groove (11) formed on inner teeth (3a) of the internally toothed gear (3), an outer-peripheral groove (12) formed on outer teeth (4a) of the externally toothed gear (4), and a flexible ring (13) mounted between the inner-peripheral groove (11) and the outer-peripheral groove (12). The ring (13) is engageable with groove inner-peripheral surfaces (11a, 11b, 12a, 12b), from the direction of the device center axis (1a), at meshing positions of the both gears (2, 4).

Abstract: A fastening friction plate is wedged between the fastening surfaces of two fastening members in order to increase the fastening force between them. The fastening friction plate has a friction plate main body of a fixed thickness, and engaging protuberances having an approximately truncated cone shape formed on the both surfaces of the friction plate main body at a fixed pitch. The friction plate main body and the engaging protuberances are integrally formed by photo-etching into the both surfaces of a steel plate material having a fixed thickness. The hardness of the fastening friction plate is equal to or greater than that of the fastening surfaces of the fastening members.

Abstract: A wave generator of a strain wave gearing has a rigid plug and a needle roller bearing mounted on the plug external peripheral surface. The plug external peripheral surface has a retainer engaging part for engaging with a retainer that would move in an axis line direction and for restricting the movement thereof along the axis line direction. The retainer has an outer ring engaging part for engaging with an outer ring that would move in the axis line direction and for restricting the movement thereof along the axis line direction. The movements of the retainer and the outer ring can be restricted without providing a separate member. A wave generator of a strain way gearing can be realized, which is provided with a roller bearing capable of restricting the movement of the outer ring with a simple structure.

Abstract: A strain wave gearing (1) has a flexible externally toothed gear (3) with a boss (7). A boss-side fastening surface (16) formed on the boss is coaxially superposed with a member-side fastening surface (15) of an output member (11), and the boss (7) and the output member are fastened by fastening bolts (13). The bolt tension of the fastening bolts (13) causes the engaging protuberances (20) of the boss-side fastening surface (16) to dig into the member-side fastening surface (15) by a predetermined dig-in depth. A large frictional force is produced in the fastening portions between the flexible externally toothed gear (3) and the output member (11). It is thereby possible to transmit the necessary torque by the bolt tension alone without using pins or a friction sheet together with the fastening bolts.
