A system for axially retaining two coaxial components includes an inner component having an annular compression groove formed in a radially outer surface thereof, an outer component having an annular engagement groove formed in a radially inner surface thereof, and a split retaining ring installed in the annular compression groove of the inner component, wherein the split retaining ring is adapted for movement between a radially compressed condition to facilitate axial engagement of the inner component within the outer component and a radially expanded condition to facilitate radial engagement of the split retaining ring in the annular engagement groove of the outer component, so that the inner and outer components are axially locked together.

Disclosed is a support structure for a ring gear (32), which includes: a clutch drum (6) coupled by spline fitting with the ring gear (32); and first and second snap rings (38, 39) mounted to a circumferential wall (62) of the clutch drum (6) and supporting the ring gear (32). The first snap ring (38) is positioned so as not to overlap with the ring gear (32) in a radial direction. The second snap ring (39) is positioned so as to overlap with the ring gear (32) in the radial direction. A length (a1) of the first snap ring (38) in the radial direction is longer than a length (a2) of the second snap ring (39) in the radial direction.

A quick-disconnect ball and socket joint includes a substantially spherical strain relief node configured to be coupled to an object, such as a cable. The system further comprises an end cap configured to capture the substantially spherical strain relief node, the end cap having a diameter that permits the substantially spherical strain relief node to pass therethrough when the system is in an open position. The system still further comprises a retaining element configured to retain the substantially spherical strain relief node in the end cap. The retaining element is attached to the end cap when the system is in a closed position and the object is prevented from being removed from capture by the end cap. However, in the open position, the retaining element may be removed from capture by the end cap by passing the substantially spherical strain relief node through a diameter of the end cap.

An internal retaining ring for placement in a bore of an outer component of a rotating assembly comprises a semi-annular body having an outer circumferential surface with a curvature defined about a first center of curvature and radially outward protruding anti-rotation tabs operable for engagement with a corresponding anti-rotation feature of the outer component. An inner circumferential surface of the semi-annular body has radially inward protruding tabs circumferentially spaced apart around the inner circumferential surface. The radially inward protruding tabs have radially inner surfaces concentric with the outer circumferential surface, and recessed portions between the radially inward protruding tabs and having curvatures defined about a second center of curvature, the second center of curvature different from the first center of curvature.

A locking plate for restricting rotation of a fastener connecting a first component of a gas turbine engine and a second component of a gas turbine engine includes a base having a planar surface receivable in overlapping arrangement with a head of the fastener. A locking portion extends from the base. Engagement between the locking portion and the first component restricts rotation of the locking portion. A key extends from the base and is connectable to the fastener such that the fastener is not rotatable relative to the key when the locking portion has engaged the first component.

The invention relates to a retaining ring for securing a component. The retaining ring includes a ring segment having an outer circumference for fixing the retaining ring in the axial direction, a recess extending along a circumferential direction of the ring segment, and a closure element for closing off the recess. In embodiments, the ring segment forms a contact surface to fix the component in the axial direction, and the retaining ring has a locking device for locking the closure element in the recess. In embodiments, the locking device is concealed at least on one side of the retaining ring facing away from the contact surface.

Disclosed is a support structure for a ring gear, which includes: a clutch drum coupled by spline fitting with the ring gear; and first and second snap rings mounted to a circumferential wall of the clutch drum and supporting the ring gear. The first snap ring is positioned so as not to overlap with the ring gear in a radial direction. The second snap ring is positioned so as to overlap with the ring gear in the radial direction. A length of the first snap ring in the radial direction is longer than a length of the second snap ring in the radial direction.

The present disclosure is direction to a stopper disposed in a driver for a steering apparatus which includes a worm gear, a bearing supporting rotation of the worm gear, and a damper buffering an impact of the bearing is provided, the stopper including: an annular body having a through hole therein allowing one side of the worm gear to pass through; and a leg on the annular body to protrude toward the damper along an axial direction of the worm gear.

This nut (1) comprises a nut main body (3) having a substantially cylindrical shape and constituted by a plurality of nut segments (3a), an outer cover (4), a restraining ring (5), an inner cover (6) comprising a restraining plate (6a) at one end portion of the inner cover (6) and serving to cover an outer circumference of the nut main body (3), and a ring-shaped spring (7) serving to bias the nut main body (3) to cause the nut main body (3) to expand radially. Protrusions (8) protruding in a circumferential direction are formed on an inner surface of the inner cover (6). Grooves (9) are formed on an outer surface of the nut main body. The protrusions (8) and the grooves (9) have slant surfaces (10) that contact each other on the same side in the axial direction.

A yoke for a transfer case output shaft includes a hollow cylindrical sleeve portion and a disc-shaped flange portion extending radially from an outer portion of the hollow cylindrical sleeve portion. The hollow cylindrical sleeve portion includes a plurality of inwardly extending splines configured to engage outwardly extending splines of the transfer case outlet shaft. The disc-shaped flange portion has a plurality of fastener openings therethrough that correspond to fastener openings through a flange portion of a companion flange. A notch is formed through the hollow cylindrical sleeve portion at an open end of the hollow cylindrical sleeve portion. A groove is formed within the inner surface of the hollow cylindrical sleeve and extends about a rotation axis of the hollow cylindrical sleeve portion. A C-clip is received within the groove for restricting axial movement along the rotation axis and includes open ends that are received within the notch.
