Bearing assemblies, apparatuses, systems, and methods include bearing assemblies where one of the bearing assemblies may include bearing surfaces defining an at least partially conical surface.

A spherical bearing for a damper system includes a first segment and a second segment with a ball therebetween. The ball includes a shaft extending therefrom. The shaft extends out of the first segment. A lubricious liner is disposed between the first segment and the second segment.

An apparatus includes an outer bearing member defining a cavity and an inner bearing member disposed within the cavity. The inner bearing member includes a spherical surface and a rod attachment opening defined in the spherical surface. The apparatus also includes an elastomeric material disposed within the cavity adjacent to the spherical surface.

A ram-body for use with a spherical bearing has an inner circumferential surface. The ram-body comprises at least a first concave section provided in said inner circumferential surface. In some examples, a second concave section may be provided diametrically opposite to the first concave section. In some examples, the concave sections may be lunular shaped. A method of manufacturing the ram-body is also described. A ram-body and spherical bearing assembly is also described.

A connector for connecting two members having a body of composite material consisting of reinforcing fibers embedded in a plastic matrix of resin, for connecting the two members to one another, and having a housing, a mounting ring installed in the housing, a swivel installed in the mounting ring and capable of allowing, by swivelling in the mounting ring, articulation between the two members to be connected, the swivel acting as a fastening area for one of the two members. The reinforcing fibers form, with the resin, plies which, when stacked, form a laminate, and the mounting ring is fastened in the housing of the body of the connector to prevent any movement of the mounting ring relative to the body of the connector.

An assembling structure for a ceiling fan has a hanging rod, a hanging ball, and a hanging bracket. A top end of the hanging rod forms a bending edge. The hanging ball has a first hole and a supporting wall. The hanging rod is mounted through the first hole. The supporting wall has a supporting platform abutting a bottom surface of the bending edge. The hanging bracket has a ball mounting segment and a ceiling mounting segment adapted to be mounted to a ceiling. The ball mounting segment has a hanging hole. A diameter of the hanging hole is smaller than a diameter of the hanging ball. The hanging ball abuts downward a periphery of the hanging hole. The hanging rod is mounted through the hanging hole. With a large contact area between the hanging rod and the hanging ball, the structural strength is high.

The invention relates to a rotary sliding vane machine (1) for fluid processing, comprising a housing (2) with a cavity (4) with a rotor (9). Vanes (12) are arranged in outwardly directed slots (13) in the rotor (9), and relative sliding between the vanes and the rotor provides spaces with variable volumes in the rotational direction. Each vane is supported by a vane bearing apparatus (102) comprising a slide bearing body (105) with a slot (13) forming a slide bearing for the vane (12), and a cylindrical convex face (116) facing away from the slot (13), and, on each side of the slot (13), a pivot bearing pad (106) with a cylindrical concave face (117) facing the slide bearing convex face (116), forming a pivot bearing for the vane.

An idler roller having a fixed shaft with at least one spherical bearing and a second bearing which may, but need not be, a spherical bearing. In some embodiments, the second bearing is slidably-mounted on a central shaft. A shell is mounted between these bearings. Any changes in dimensions resulting from changes in temperature may them be accommodated by sliding movement of the second bearing, sparing the shell from distortion by bending or buckling. In other exemplary embodiments, the spherical bearing includes a first housing element fixedly-mounted on a central shaft and a complementary first free element disposed against the first housing element. A second bearing element is mounted on the central shaft, and a shell is attached to the first free element and rotatably-mounted to a second bearing element with a biasing element mounted on the central shaft urging a second free element away from the first free element.

A spherical ball joint having an inner ring and an outer ring that cooperate by way of respective truncated spherical contact surfaces, the inner ring having a central bore with a cylindrical bore portion. The spherical ball joint includes a cylindrical sleeve mounted securely in the cylindrical bore portion, the sleeve configured to be mounted around a shaft, the sleeve being made of a wear-resistant material different from that of the inner ring.

A spherical bearing for a damper system includes a first segment and a second segment with a ball therebetween. The ball includes a shaft extending therefrom. The shaft extends out of the first segment. A lubricious liner is disposed between the first segment and the second segment.
