Abstract: A bearing body is provided. The bearing body includes first and second support surfaces inclined so as to slope upward from a side on the imaginary central vertical plane passing through an axis of a rotating shaft to be supported toward one and the other outer sides in the width direction of the rotating shaft. First and second transitional regions that respectively make transitions from the first and second support surfaces to a first and end surface of the bearing body on one side in the axial direction of the rotating shaft have a curved shape projecting obliquely upward such that an orientation of a normal line changes from a perpendicular direction to a parallel direction with respect to the axis of the rotating shaft toward one side from the other side in the axial direction of the rotating shaft.

Abstract: An electric fluid pump may include a wet section having a pump wheel and a permanently excited rotor of an electric motor arranged therein. The electric fluid pump may include a dry section having a stator of the electric motor arranged therein. A containment shell may be included configured to separate the wet section from the dry section. The dry section may include control electronics for controlling the fluid pump. The control electronics may connect in a heat-transferring manner to the containment shell and the wet section via the containment shell.

Abstract: A resilient (slide) bearing device, for example for use in connection with support of a rotating element in a vessel, where the bearing insert comprises devices for gradual absorption of loads to which the bearing is exposed. This is achieved by the devices for gradual absorption of loads comprising two or more elastic elements with different modulus of elasticity, where the elements are furthermore placed in layers. A method for maintenance and service of the device is also presented.

Abstract: A roller device of the present invention includes a roller including a shaft, a bearing for rotatably supporting the shaft, a pressing device for pressing the bearing, and a lug protruding from the bearing in the axial direction of the roller. The pressing device is implemented as a pair of hook members deformable away from each other in a direction perpendicular to the axis of the roller.

Abstract: The invention provides a submersible pumping system which includes a motor containing self-centering rotor bearing assemblies. Each rotor bearing assembly in accordance with the present invention includes a sleeve, a journal, and at least two seals. The journal is preferably disposed about the sleeve which is keyed to the power transmission shaft of the motor. The journal has a peripheral surface which is configured to have at least two circumferential support regions which are spaced apart from one another. Each of these circumferential support regions supports a corresponding seal. Each seal includes an interface member and an activating member. When in place in a rotor section of a submersible pump motor, the seals frictionally engage the inner surface of the stator and exert a centering force against the journal and thus against the bearing sleeve and the power transmission shaft.

Abstract: At least two rigid segments of a tapered bearing sleeve are interconnected y deformable elastomeric sections for rotational support of a shaft or pin about a fixed axis established within a housing into which the bearing sleeve is inserted and held therein by an adjustment closure ring under axial pressure of a spring through which radial clearance between the sleeve segments and the shaft varied during transient loading of the shaft, is minimized to reduce vibrational noise and wear.

Abstract: A roll-feed apparatus which is removably attached to a printer/plotter that has a self-alignment feature. Media, such as paper, vellum or film is pulled through the printer/plotter. However, a back-tension is created in the roll-feed apparatus by creating a pre-determined force on the shaft to which a roll of media is mounted. By increasing the force on the shaft, frictional drag is induced impeding the shaft's rotation. It has been found that the rotational impedance, in conjunction with the pull of the printer/plotter, corrects any misalignment of the media in approximately six meters of media run.

Abstract: A structure for supporting a photoconductive element included in an image forming apparatus. The shaft of the photoconductive element is supported by two adjoining bearings. One of the bearings is pressed against a framework or a slider by a leaf spring to be thereby fixed in place. The other bearing is movable relative to the framework or the slider and pressed against the shaft by another spring in the same direction as the first-mentioned bearing. The structure prevents the shaft and, therefore, the photoconductive element from tilting or shaking to thereby prevent an exposing position on the element from being changed.

Abstract: A bearing system rotatably supporting a shaft or any other similar machine element is unrotatably fitted in a bearing inserting aperture. The bearing system comprises a fixed bushing which is located more adjacently than the shaft to a portion thereof on which external force acts, and is fixed within the bearing inserting aperture. A movable bushing cooperates with the fixed bushing to hold the shaft, and is allowed to advance or retreat relative to the fixed bushing. Springs allow the movable bushing to approach the fixed bushing. If the outer circumferential surface of the shaft and the inner peripheral surface of the fixed bushing are worn out or abraded, the movable bushing is moved in proportion to the wear or abrasion amounts of the shaft and the fixed bushing in the direction of the fixed bushing by using the springs.

Abstract: The joint comprises a male element drive in rotation by a driving shaft (AM) and provided with radial arms (340) on each of which are mounted two rolling segments (310) trapped in rolling tracks (R) of a female element (312), expansible elastically yieldable bearing bushings (600) interposed between the arms (340) and the rolling segments (310), each bushing being formed by two semi-cylindrical semi-bushings (600) which are prevented from moving axially and in rotation relative to the arm (340) and are radially expansible. Each semi-bushing (600) is provided with a stud (410) for locating it on the associated arm (340), this stud being placed inside the semi-bushing on the axis of symmetry (Y--Y') of the latter. This arrangement avoids any risk of breakage of the bushings when the joint is operating at maximum angularity by avoiding any sudden increase in the retaining force of the locating studs in this extreme position of the joint.

Abstract: A small fan which is constructed as compact axial fan with a central driving motor retained by way of a flange and a bearing support tube, and in which the housing of the fan forms a flow duct that surrounds the rotor; the bearing support of the shaft of the driving motor is constructed as one-piece slide bearing unit which is secured radially in an axial partial area of the bearing support tube by a sliding seat; the bearing support tube consists of a material which can be injection-molded.

Abstract: An adjusting transmission of a motor vehicle for a motorized seat adjustment with a transmission housing and a worm arranged on a bearing shaft which is supported at the transmission housing in two shaft bearing parts retaining the shaft and inserted into a respective housing aperture on both sides of the worm; at least one of the two shaft bearing parts is thereby tiltably supported within the coordinated housing aperture in at least a plane containing the bearing shaft axis. A self-alignment of the two bearing parts is achieved thereby so that one obtains without large expenditures a transmission operation which is low in friction and freely movable. The bearing part can be constructed as ring with spherical surface which abuts at prism surfaces of the housing aperture as well as of a pressure member.

Abstract: A thrust bearing device including a bearing oil tank containing a lubricating oil, a plurality of bearing shoes for slidably journaling a rotary member located in the bearing oil tank, the bearing shoes each being segmental in shape, and a support device for the bearing shoes. The support device for the bearing shoes is interposed between the bearing shoes and the bottom of the bearing oil tank and immersed in the oil, including pressure receiving members each having spread-apart two legs, and resilient members. The pressure receiving member are each formed on its upper surface with a portion for supporting the associated bearing shoe and on its undersurface with the spread-apart two legs, one of the shoes being constructed to receive a lower thrust load than the other leg. The resilient members are each located beneath the leg of the associated pressure receiving member that has the lower thrust load applied thereto.
