Abstract: This invention is to provide a ceramic sliding bearing which is possible to support the axis to which the radial load and the thrust load are applied simultaneously or selectively, and also this invention is to provide a bearing having a small number of parts by constructing the inner and the outer rings by means of ceramics.

Abstract: The ceramic bearing constructed by being allowed to contact the ceramic outer ring slidably with the ceramic inner ring is provided with a latching member to prevent the transfer of the ceramic inner ring in the axial direction at the inner or the outer ring of said ceramic product.The bearing constructed by the sliding contact of the ceramic inner ring with the ceramic outer ring can prevent the occurrence of the transfer of the inner ring in the axial direction with respect to the outer ring by providing a latching member which prevents the transfer of the inner ring in the axial direction at the inner or outer ring. Accordingly, there is no anxiety of separation of the outer ring from the inner ring.

Abstract: A flanged half bearing for motor vehicle engine applications. The flanged half bearing is of the type having a semi-cylindrical shell provided with half thrust washers. The thrust washers are connected to the shell through the coacting of appendages on the thrust washers and recessed portions on the curved edge of the shell. Upon the insertion of the appendages into the recessed portions, the appendages are swaged to retentively engage the washer along the edge of the shell. After swaging, the dimensions of the recessed portion and appendages are such that the washer is capable of axially floating fore and aft relative to the shell, but is incapable of being disengaged from the shell. This provides a flanged half bearing which remains assembled during installation and allows for the accommodation of axial forces and thermal influence of the engine.

In the case of the present shaft bearing assembly, an oil-impregnated dampening disc made of an absorbent material the capillary action of which is greater than that of the porous bearing block is disposed between the thrust collar of the shaft and the axial end face of the bearing block. The shaft bearing assembly is particularly suitable for electric motors of smaller size and is effective in reducing motor noise.

Abstract: A dynamoelectric machine has a rotor affixed to a shaft which is journaled at each end by a bearing assembly. These elements preferably are assembled in a housing. A simplified system for controlling end movement or end play of the shaft during transport of the motor and motor start-up and coast-down eliminates the need for end play washers normally associated with motor construction. The system includes a stop (3) molded into an endshield of the motor so as to be integrally formed in one end wall of the housing, while a spacer (7), which can bear against the bearing at the other end of the shaft restrains end play in the opposite direction.

Abstract: A sleeve bearing comprises two sleeves which are mounted for relative rotation one inside the other and which contact one another at radially outwardly extending flanges. The outer sleeve consists of rubber and has a sealing lip on its flange. The sealing lip reaches around the profile of the projecting flange of the inner sleeve and its sealing edge is resiliently biased against the outer end face of the inner sleeve flange. In addition to the sealing edge, the sealing lip can also have a sealing surface which, in cooperation with secondary machine parts, constitutes an additional seal for protecting the sealing edge.

Abstract: In a swivel bearing for a braking device the fixed machine part is provided with a flange which has friction surfaces for damping the swivel motion. A flange sleeve made of sheet metal axially and radially surrounds a flange which adjoins the front side of a sleeve section belonging to the swivel arm. The resulting annular space contains, besides the flange, an axially acting spring washer. The flange sleeve itself may optionally have an axial spring action. The flange sleeve is secured axially and against torsion at the sleeve section by means of a turned edge or similar means. The result is a compact arrangement which does not easily disassemble, even in an unmounted condition.

Abstract: An article dispenser of the type having a sphere enclosed vessel, the sphere having at least one cavity for transferring an article, such as a pill, from inside the vessel to outside the vessel, employs a novel improvement in the manner of suspending the sphere on the vessel. Specifically, a cradle bridging the opening of the vessel provides a track of arcuate shape and the sphere has an annular groove of appropriate depth to form a central shaft for rotatably engaging the track. The sphere is readily removable for refilling the vessel and for assembly. A plurality of diagonally oriented guards assure free rotation of the sphere with articles being transferred in the cavity.
