  • Patent number: 5961219
    Abstract: A split taper bushing assembly includes a bearing member, an inner sleeve received in a hollow center defined by the bearing and an optional outer sleeve which receives the bearing member in an open center defined therein. The bearing member also includes a tapered skirt. The skirt includes a slit which permits the bearing member to contract during assembly to account for variances in its dimensional tolerances, thus ensuring a proper fit between the bearing member and any mating part. The bearing member is formed using a polyurethane type material. Since such a material resists deterioration due to contact with lubricants commonly used in the automotive industry, the bushing assembly can be relubricated during operation without any destructive affect on the bearing member.

  • Patent number: 5803336
    Abstract: A pinch roller type tape drive assembly which is one of the elements composing a tape driving system of a VCR and ensures stable running of a tape. The pinch roller type tape drive assembly has a capstan for rotating at a constant velocity and a pinch roller which self-aligns, for pressing a tape against the capstan so as to drive the tape at the constant velocity together with the capstan. When the pinch roller is pressed against the capstan, an annular self-aligning member disposed between an inner sleeve and an outer sleeve is compressed in the direction of the contact point of the capstan and the pinch roller toward a pinch roller shaft, thereby holding the gap between the capstan and the pinch roller.

  • Patent number: 5768974
    Abstract: A swash plate type compressor includes an improved thrust bearing for axially supporting the swash plate. The bearing is of a composite type, and includes at least two elastically deformable slide bearing elements. The swash plate and the cylinder block each have seat portions, which are of different diameters. The two bearing elements are compressed between the respective seat portions into an elastically deformed conically-shaped state, with the amount of conical deformation depending upon the amount of axial compression that is applied to the bearing by tightening the assembly bolts of the compressor. In operation, one of the conically shaped slide bearing elements is pressed outwardly against the other by centrifugal force as the compressor shaft rotates. During start up and low speed operation of the compressor, this centrifugal force will have minimal effect, and the bearing elements will rotate with respect to each other, keeping internal frictional resistance low.

  • Patent number: 5288152
    Abstract: A replacement bearing is provided for use in rebuilding the nominally disposable toner cartridges that are commonly used in popularly priced electrostatic printers and copiers. When the bearing is rotated into its final position about the shaft of a toner roller, an oversize portion of the bearing is forced into a position that ensures that both the bearing retainer and the toner roller are restrained in a precise alignment. A slot, that has a predetermined gap when installed, is preferably provided in the bearing, and a decrease of the width of this gap is indicative of bearing wear. The precise alignment and wear indication means that are provided by the new bearing allow an operator to rebuild a toner cartridge that had been demonstrating the "right side problem", and to subsequently monitor the wear of a replacement bearing so as to prevent recurrence of copy degradation.

    Abstract: A mechanism for a press section of a papermaking machine including a press having first and second press rolls forming a pressure loaded press nip therebetween with a support frame and end bearings for the first roll with a support carrying the end bearings on the frame including first and second layers of deformable elastic material with a plate connected to the bearing between the layers of material and plates on the outer surfaces of the layers connected to the frame so that vibrational forces normal to the direction of movement of the web through the nip are passed through the layers of elastic material.

  • Patent number: 4435661
    Abstract: A submersible pump electrical motor has a bearing member that is resilient. The submersible pump motor has a stationary stator within which a rotor is rotated. The rotor is divided into sections, with bearings located between each section for maintaining the shaft in alignment. The bearings frictionally engage the stator wall. The bearing has slots extending through its periphery to provide flexibility. The slots incline into the direction of rotation of the shaft to resist rotation of the bearing member.

  • Patent number: 4380860
    Abstract: A socket of yieldable semi-rigid plastic material is formed with an external circumferential groove for receiving the periphery of an opening in a linkage member. The periphery of the opening is deformed out of the plane of the surface of the linkage to produce an effective thickness approximately the thickness of the groove, providing a method to assure a secure fit in cases where the thickness of the linkage material is either greater than or less than the width of the groove.
