Abstract: A wave generator (4) of a strain wave gearing (1) is provided with a rigid plug (5), a wave bearing (7) mounted to the ellipsoidal outer peripheral surface (6) of the rigid plug, and four elastic claws (11) that rotate integrally with the rigid plug (5). The balls (10) of the wave bearing (7) include balls (10a) in a loose state and balls (10b) in a tight state. The loose-state balls adjacent to the tight-state balls are applied with braking force by the elastic claws (11) immediately before they transition into a tight state, and the orbital motion thereof is temporarily prevented or suppressed, whereby the gaps between the loose-state balls and the adjacent tight-state balls are secured. It is possible to prevent increase in rotational torque, damage to the balls or other defects due to ball-to-ball contact by the tight-state balls.

Abstract: The wave generator of a strain wave gearing is provided with an ellipsoidally contoured wave generator plug and a wave generator bearing. The wave generator bearing is provided with an annular body fitted between inner and outer races in a sliding contact state. The annular body is composed of an endless coil spring and has a rigidity that is able to maintain a constant gap between the inner and outer races. The annular body also has a specified overall flexibility in the radial direction so that the annular body can be flexed into an ellipsoidal shape by the wave generator plug. Since sliding occurs between the annular body and the inner race when the wave generator plug rotates, it is possible to generate a wave motion in an externally toothed gear with a small rotational torque. The wave generator of a strain wave gearing is provided with an ellipsoidally contoured wave generator plug and a wave generator bearing. The wave generator bearing is provided with an annular body fitted between inner and outer races in a sliding contact state. The annular body ...more ...less

Abstract: A sliding bearing has an outer ring, an inner ring, an annular-shaped raceway formed between the two rings, and a sliding body mounted on the raceway. The raceway has rectangular cross-section or a rhomboid cross-section formed from an outer-ring-side V groove and an inner-ring-side V groove. The sliding body is, for example, formed of an endless coil spring, and the outer peripheral surface of the circular contour thereof is in contact in a four-point contact state with four first through fourth raceway surfaces of the raceway. A sliding bearing having a compact configuration that can bear a moment load can be achieved.

Abstract: A wave generator of a strain wave gearing uses a plurality of solid displacement elements to flex a flexible externally toothed gear into a non-circular shape and partially mesh the externally toothed with a rigid internally toothed gear. The solid displacement elements are obtained by curving a monomorphic or bimorphic type rectangular plate-shaped element into an arc shape and can be deformed from an arc shape to a semispherical shape by energization, the semicircular shape having a smaller radius than the arc radius of the arc shape. A wave generator can be realized, which can bear a large load torque by utilizing changes in rigidity, deformation amount, and deformation force associated with the deformation of the solid displacement elements.

Abstract: A wave bearing (7) of a wave generator (5) of a strain wave gearing (1) is provided with steel or stainless steel cylindrical hollow rollers (12) between an inner-race-side raceway surface (9) and an outer-race-side raceway surface (10), the hollow rollers serving as rolling elements. The ratio Di/Do of the inner diameter Di to the outer diameter Do of the hollow rollers (12) is set to 0.95 or more. The relative radius of curvature of hollow rollers (12) that have been flexed into an ellipsoidal shape increases with respect to the inner-race raceway surface (9) and the outer-race raceway surface (10) with which the hollow rollers (12) are in contact, and the Hertz maximum contact stress is reduced. The hardness of the hollow rollers (12), the inner-race raceway surface (9), and the outer-race raceway surface (10) can be reduced.
