The application is a motor capable of reducing vibration. A motor includes a shaft, a pair of bearings, a sleeve accommodating the pair of bearings, a magnet fixed at one of the shaft and sleeve, a coil fixed at the other of the shaft or the sleeve and opposing the magnet, and an elastic member disposed between the pair of bearings and satisfying Expression 1. D is an outer diameter [m] of the elastic member, d is a wire diameter (p [m] of the elastic member, γ is a unit volume weight [kg/m.sup.3] of a material of the elastic member, S is a no-load rotation number [rotation/min] of the shaft, and g is gravitational acceleration.

A centrifugal separator is configured for processing a product by separating a relatively, heavy component and a relatively light component therefrom. The centrifugal separator includes a spindle supported by a stationary frame, A drive unit acts on a rotating member mounted on the spindle to rotate the spindle. A centrifuge rotor mounted to the spindle encloses a separation space. An upper bearing housing is mounted to the stationary frame and supports bearings including an outer bearing ring attached to the upper bearing housing and an inner bearing ring attached to the spindle. The upper bearing housing is mounted to the stationary frame via an elastic member permitting the upper bearing housing and the spindle to move radially, and via an upper tilting member permitting the spindle to tilt during operation of the centrifugal separator.

A self-aligning bearing support assembly for supporting a radial load rotary or linear bearing. The bearing support assembly has a main axis (A) and includes an outer sleeve and an inner sleeve at least partially received in the outer sleeve. The inner sleeve has an axially extending bore for supporting a rotary or linear bearing or for forming a bearing surface of a bearing. Three or more circumferentially separated chambers are formed between the inner sleeve and the outer sleeve. Each chamber is confined in all directions by walls of the assembly. A lump of a substantially incompressible material fills each of the at least three chambers with the chamber concerned substantially completely enclosing the lump.

To reduce the effect of a steering operation on feeling. A rack bush comprises: a bush body that is accommodated in a cylindrical housing, supports a load exerted on a rack bar while allowing the rack bar to move in the direction of an axial center O, and can be extended and retracted in a radial direction; and an elastic ring mounted on the bush body. The bush body has a mounting groove for mounting the elastic ring, the mounting groove being formed peripherally in an outer peripheral surface, and the mounting groove having a large-diameter part where the circumferential radius of a groove bottom is a first radius r1, and a small-diameter part where said radius is a second radius r2 that is less than the first radius r1. This configuration allows the formation of an elastic ring protruding part, in which the elastic ring protrudes greatly from the outer peripheral surface of the bush body, and an elastic ring embedded part, in which the elastic ring is embedded in the outer peripheral surface of the bush body.

A laminated elastomeric journal bearing has an outer sleeve having an inner surface, at least a portion of each end of the inner surface being a concave surface of revolution, and an inner sleeve having an outer surface, at least a portion of each end of the outer surface being a convex surface of revolution. Alternating layers of elastomer and metal are located between the sleeves, with adjacent surfaces of the layers and the sleeves being adhered to each other.

A gantry assembly includes a rotor, a stator and a bearing for coupling the rotor and the stator. The bearing includes an inner ring connected with the rotor or stator, an outer ring connected with the other one of the rotor and the stator and rolling elements between the two rings. The ring connected with the stator, preferably the outer ring, includes one or more damping washers disposed between the ring and the stator, each washer being disposed about one threaded fastener connecting the ring with the stator. Also, one or more damping cylinders are each disposed within a mounting hole of the ring connected with the stator and about a threaded fastener disposed within the hole. The bearing ring connected with the rotor may also include damping washers between the ring and the rotor or/and damping cylinders disposed within mounting holes receiving fasteners connecting the ring with the rotor.

A rubber bush with an inner part (2) which extends in an axial direction (x), an outer sleeve (3) which surrounds the inner part (2) at a spacing and comprises two half shells (4, 5) which are configured as identical parts, and a rubber body (6) which is arranged between the inner part (2) and the outer sleeve (3), wherein the half shells (3, 4) are connected to the inner part (2) by the rubber body (6) and, at their circumferential-side ends which face one another, have projections (7, 8) and depressions (9, 10), into which the projections (7, 8) are insertable.

A bearing assembly of an electric drive assembly for a vehicle includes an insulating device having a sleeve with an electrically insulating coating, and a bearing device disposed in the sleeve. In an example embodiment, the sleeve has an inner peripheral surface and an outer peripheral surface, and the outer peripheral surface is formed by the electrically insulating coating. In an example embodiment, the sleeve is formed from steel, and the electrically insulating coating is formed from a plastic material having an electrically insulating property. In an example embodiment, the sleeve is designed as a cylinder having an end face with an outer side, and the electrically insulating coating is disposed on the outer side. In an example embodiment, the bearing device is a floating bearing axially movable relative to the sleeve.

A connecting assembly for connecting two structures of an aircraft, the connecting assembly including a central element featuring a through-hole, preferably a bore, configured to make a connection with one of the two structures by virtue of a fastener element including a shank inserted into the through-hole. The connecting assembly further includes a plurality of shock-absorbing elements made from a deformable material. Each of the shock-absorbing elements are, on the one hand, secured to the central element and, on the other hand, configured to bear against a surface of the other of the two structures. An aircraft part includes such a connecting assembly.
