摘要： A flat wave-motion gear (1) which has an input shaft (4) supported rotatably at both end portions thereof between first and second end plates (2, 3). A wave-motion gear mechanism is incorporated between these end plates (2, 3), and a cross roller bearing (8) is provided on an outer circumferential side of the wave-motion gear mechanism. The wave-motion gear mechanism comprises a rigid internal gear (5), a silk hat-shaped flexible external gear (6) provided on the inner side of the internal gear, and an intermittent driving force generator (7) provided on the inner side of the external gear (6). An annular boss (64) of the flexible external gear is held between an outer race (81) of the cross roller bearing (8) and the second end plate (3), whereby these three members are fastened to one another. The rigid internal gear (5) is held between an inner race (82) of the cross roller bearing (8) and the first end plate (2) whereby these three members are fastened to one another. The input shaft (4) may comprise a hollow shaft. Owing to the employment of such a structure, the apparatus as a whole can be formed flat and to a length slightly larger than the axial length of the flexible external gear. Since the outer race of the cross roller bearing can be used also as a housing of the apparatus, the apparatus can be formed compactly by a reduced number of parts.

摘要： In a rotation transmission mechanism (1) that transmits the rotational driving force of a motor (2) to a load-side member (5) via a speed reducer, a strain wave gearing (3) is used as the speed reducer, and the allowable load torque of members in the powertrain other than the strain wave gearing (3) is greater than a predetermined upper-limit load torque. The allowable load torque of the strain wave gearing (3) is dictated by the ratcheting torque, which is set so as not to exceed the upper-limit load torque. In an overload state, ratcheting is generated in the strain wave gearing (3), so that the strain wave gearing functions as a mechanical fuse. Other power transmission members can be protected from an overload state without adding a separate member such as a torque limiter.

摘要： Provided is a method for manufacturing a base material for a wave gear which enables the effective suppression of man-hours and manufacturing cost while providing the required strength and elastic deformation characteristics for an external gear of a wave gear. In this manufacturing method, steel having a carbon content of 0.48% or less is subjected to primary molding by being cold worked into the shape of an external gear for a wave gear. The resulting primary molded article is heated to a temperature range (T 1 ) in which the main phase of the metallographic structure thereof forms an austenitic structure. The main phase of the metallographic structure is formed into bainite by carrying out quenching to a predetermined temperature (T 3 ) higher than the martensitic transformation starting temperature and maintaining the temperature for a predetermined time. The product is then cooled to normal temperature.

摘要： An externally toothed gear of a dual-type strain wave gearing is provided with first and second external teeth (7, 8) having different teeth numbers. The first and second external teeth (7, 8) are flexed by a wave generator by the same flexing amount, into an ellipsoidal shape. The tooth depth (h1) of tooth profiles (70) of the first external teeth (7) having a low teeth number is smaller than the tooth depth (h2) of tooth profiles (80) of the second external teeth (8) having a high teeth number. A dual-type strain wave gearing can be achieved with which the first and second external teeth having different teeth numbers can be suitably flexed to form excellent meshing states with respective internally toothed gears.
