Abstract:
A seal assembly for sealing a space between a first component and a second component includes a seal base body disposed on the first component and having at least first and second seal lips configured to run on a running surface of the second component with the seal lips contacting the second component at first and second axially spaced locations, the seal base body including an annular channel having an opening facing in the axial direction, and at least one cylinder comprising a bimetallic shape-change element, the cylinder having a first end in the annular channel of the seal base body and a second end outside the annular channel, at least a portion of the cylinder being located axially between the first seal lip and the second seal lip and radially inward or outward from the second seal lip.
Abstract:
A crankshaft or connecting-rod bearing assembly of an internal combustion engine includes a bearing journal configured to function as a bearing inner ring, and a bearing outer ring surrounds the bearing journal. At least one row of rolling elements is disposed between the bearing journal and the bearing outer ring, the rolling elements are held by a cage, and the cage includes at least two cage segments, each of which extends around a circumferential section of the bearing journal. Furthermore, the at least two cage segments are connected to each other in a materially-bonded manner at at least one joint lying in the circumferential direction.
Abstract:
A bearing assembly (1) includes at least one bearing (3) that rotatably supports a cylindrical roller tube (2). A cushioning layer (5) is disposed, directly or indirectly, between a ring (4) of the bearing (3) and the cylindrical roller tube (2). At least one contact surface (6, 7) for the cushioning layer (5) extends over a defined axial distance (L) at an angle (α) to the rotational axis (A) of the bearing assembly (1).
Abstract:
A bearing arrangement used in a medical device in which a rotating component is supported relative to a stationary housing includes a bearing comprising an inner ring and an outer ring, with the inner ring being connected to the component which is to be supported and the outer ring being connected to the housing. To increase quiet running of the rotating component, the connection between the inner ring and the component to be supported and/or between the outer ring and the housing is produced by an annular element which is made of plastic.
Abstract:
A drive device for pumps consists of a drive pulley to drive a shaft. The shaft assembly includes an inner bearing seated in the housing bore, an outer bearing seated on a neck of a pump cover, a cover disk with an outer edge, covering the outer bearing and the neck of the pump cover laterally from the outside and is connected to the drive pulley, and a center of the shaft, a spring for the automatic play eliminating adjustment of the radial and axial load-supporting outer and inner bearing.
Abstract:
In a drive device for pumps consisting of a pump impeller mounted in a pump chamber, a pump cover covers the pump chamber and has an extension and a bore passing from the pump chamber to the outside. A shaft is connected at its inner end to the pump impeller and at its outer end in a torsion-proof manner by way of a coupling element to a drive wheel. A bearing supports the shaft and drive wheel in the housing bore and extension respectively. The coupling element is formed by an external edge rigidly connected to the drive wheel and covers the outer bearing and the extension laterally on the outside. A cover plate with a center section connects in a torsion-proof manner to the shaft, and is adjusted to elastically adjust the cover plate relative to the pump cover either inward toward the pump chamber or outward away from the pump chamber, thereby providing for automatic adjustment of the radial and axial load-supporting bearings means to remove their play.
Abstract:
A method for producing a cage, especially a roller cage of sheet material by punching out the roller element pockets, consisting of the steps of stamping the sheet material in the direction of the sheet thickness in at least predetermined areas of the punching line for forming the rolling element pockets and thereafter forming the pockets by a punching operation.
Abstract:
A sealing device for bearing bushings, especially for universal joints including a cup-shaped bearing bushing overlying a universal joint pin comprising an inner sealing ring, a sheet metal part connected to the bearing bushing adapted to fix the inner sealing ring in place in an axial direction, and an outer sealing ring provided on a shoulder of the joint pin supported in the bearing bushing, the inner sealing ring has a retaining part between the rolling elements and the free end of a preferably radially oriented shank of the sheet metal part, which has one or more openings, which connect the spaces defined by the outer sealing ring, the inner sealing ring, and the sheet metal part to each other.
Abstract:
A thin-walled bearing bushing produced by deep drawing, in particular for the seating of pins in universal joints, including a cylindrical sleeve section with a bottom section closing the sleeve off on one end. One or more concentric depressions are axially pressed in the outer surface of the bottom surface near the resulting sharp peripheral edges. A plurality of indentations, displaced radially inward relative to the depressions and reducing the wall thickness of the bottom section of the bushing, are provided on the outer surface of the bottom section so that the uniform bushing inner surface will have a large axial load-carrying capacity.
Abstract:
A method for making by a deep drawing process a thin-walled bearing bushing comprising a cylindrical sleeve section and a bottom section closing one end of the sleeve section having an outer peripheral rim at the juncture of the sleeve and bottom sections of small cross sectional radius including the step of forming an annular groove which is deep relative to the normal thickness of the bottom section and has a sharp profile in one face of the bottom section adjacent the juncture of the sleeve and bottom section, the groove being impressed axially to effect radial displacement of the material outward into the area of the peripheral rim.
