The invention relates to a bearing arrangement for a shaft in a turbocompressor having at least one water-fed hydraulic bearing, which is configured to support for rotation an axle of the turbocompressor, wherein the water-fed hydraulic bearing encloses the shaft at a circumference of the shaft to form a bearing gap therebetween; and wherein the water-fed hydraulic bearing is configured to allow water to flow through the bearing gap to support the shaft hydraulically; and two seals, which are designed to seal the bearing gap against the shaft; and wherein gas from the turbocompressor is applied to the two seals outside the bearing gap to seal the bearing.

A gas bearing for a compressor includes a bearing portion and a sealing portion mounted to a bearing housing of the compressor via one or more dampers, and the sealing portion being fixedly connected to the bearing portion, and a vent with an inlet in the bearing. The bearing portion has an inner radial surface for radially supporting a shaft of the compressor. The sealing portion has a sealing surface. The inlet of the vent disposed between the inner radial surface and the sealing surface. The sealing surface and a rotating surface form a path that extends along the sealing surface. The path extending from a pressurized volume of the compressor to the vent, and the pressurized volume containing a fluid.

An autonomous mobile device has a tower extending from a main body. The tower pans from left to right. An extensible mast may extend through, and pan with, the tower. An upper section is attached to the tower by a hinge and may tilt with respect to the tower. The upper section may include a touchscreen or other devices. An assembly with separate pan and tilt motors allows for the tower and attached upper section to pan while also allowing the upper section to tilt independently of the panning motion. The tilt motor is within the portion of the assembly rotated by the pan motor. The tilt motor drives a worm gear in the tower to rotate a tilt axle. An asymmetric friction hinge connects to the upper section to the tilt axle. Rotating the tilt motor rotates the worm gear, rotating the tilt axle and the attached upper section.

A bearing assembly for a turbo-engine with a bearing and parts of a bearing temperature detecting device. The bearing includes a main body having a thermoplastic bearing layer. A space is defined in the interior of the main body and of the thermoplastic bearing layer for accommodating parts of the bearing temperature detecting device. The space has a through hole having a first opening in the thermoplastic bearing layer and a second opening located in the main body. The parts include a temperature conducting element, a temperature sensor, and a securing fixture that attaches the temperature conducting element. The first opening of the through hole has a chamfer and the first end of temperature conducting element has a head which is correspondingly shaped to the chamfer in a form fitting manner. The center-axis of the temperature sensor extends transversely to the center-axis of the temperature conducting element.

In order to effect a seal a porous material which comprises one side of two opposing surfaces is used to restrict and evenly distribute externally pressurized gas, liquid, steam, etc. between the two surfaces, exerting a force which is opposite the forces from pressure differences or springs trying to close the two faces together and so may create a non-contact seal that is more stable and reliable than hydrodynamic seals currently in use. A non-contact bearing is also disclosed having opposing surfaces with relative motion and one surface issuing higher than ambient pressure through a porous restriction, wherein the porous restriction is part of a monolithic porous body, or a porous layer, attached to lands containing a labyrinth, the porous restriction and lands configured to not distort more than 10% of a gap created from differential pressure between each side of the porous restriction.

A spherical plain bearing includes an outer ring having a concave interior spherical surface, and an inner member having a convex exterior spherical surface. The inner member is pivotally disposed in the outer ring such that the inner member and the outer ring are angularly misalignable relative to one another. The spherical plain bearing includes an angular misalignment restraint system which includes an inner member restraint feature on the inner member and an outer ring restraint feature on the outer member. The first and second portions are spaced apart when the inner member and the outer ring are angularly misaligned relative to one another by less than a predetermined maximum angle θ, and come into abutment when the inner member and the outer ring are angularly misaligned relative to one another by angle θ. The abutment prevents any further relative angular misalignment of the inner member and the outer ring.

A rotation induction device for a vehicle includes: an upper case having a piston rod disposed therethrough; a lower case disposed adjacent to the upper case and having the piston rod disposed therethrough; a center plate disposed between the upper case and the lower case such that the piston rod passes through the center plate, to induce rotation of one or both of the upper case and the lower case; and a friction restraint part formed on one or both of the upper case and the lower case, to restrain friction with the center plate.
