Coupling Supported By Independent Bearing Patents (Class 403/26)
  • Patent number: 10260567
    Abstract: Disclosed systems couple two rotational shafts in axial alignment with each other such that torque can be transferred between the shafts without undesired loading occurring. A shaft coupling system can include an annular mounting housing positioned around a juncture of two rotational shafts with bearings positioned between the shafts and the housing so that the housing prevents radial motion of the shafts while allowing the shafts to rotate about their common axis. One shaft can be coupled to an engine and the other shaft can be coupled to a shaft-driven device such as a hydraulic pump. One shaft can be smaller in diameter and piloted into a recess in the end of the other shaft. In some embodiments, the two shafts have about the same diameter and are linked via a torque coupler within an annular mounting housing that allows rotation but limits radial motion of the shafts.

The second collar assembly defines a bore therethrough which is dimensioned to be substantially larger than the shaft exterior configuration in which the assembly is to be mounted. The disparity in the bore sizes permits the second collar to be displaced laterally as well as axially along the shaft with respect to the shaft and along the planar interface of the two-collar members. The two-collar members define the respective exterior engagement surface adapted to engage and otherwise abut against a member stacked on the shaft.

A spindle clamp having a male bayonet mount is inserted through the bearing cap and engages a mounting cup having a female bayonet mount. A belleville washer is mounted onto the clamp between the bearing cap and the head portion of the clamp. The clamp and cup are designed so that the washer is compressed as the bayonet mount engages. This exerts a constant uniform pressure on the bearing cup as well as restraining the bayonet mounting from disengaging. The bearing cap is held tightly against the exterior of the housing as well to seal the bearing and the inner housing from the exterior environment.

  • Patent number: 5040779
    Abstract: A paper delivery apparatus for delivering paper to a predetermined place by driving a roller support shaft with a the paper coming in contact with roller attached to the roller support shaft. The roller support shaft and the drive shaft are connected to each other between a pair of lateral plates. Bearings are attached to the roller support shaft at both ends thereof and are axially movably supported by bearing support members. The roller support shaft together with the bearings may be readily removed from the bearing support members by moving the roller support shaft or the bearings in the axial direction.

  • Patent number: 4938622
    Abstract: A first coupling device is particularly destined for a dispersing apparatus and comprises a first coupling part having a flange and a tubular connecting piece fixed thereto, the connecting piece having at least two borings for receiving one ball each, and a concentrically surrounding, free moving ring. The diameter of the boring is slightly greater than that of the balls, but in the vicinity of the inner surface of the connecting piece, it is slightly smaller so that the balls may in part protrude into the interior of the connecting piece. The lower portion of the ring has an inner circular recess so that, when the ring is raised, the balls may travel backwards into the circular recess. The second coupling part is adapted to be introduced into said connecting piece and has circular recesses for receiving said balls.Another coupling device for the slippage free connection of high speed rotating shafts of dispersing apparatuses comprises two coupling parts which both have six teeth whose flanks are of 60.

    Abstract: A disengagable coupling comprising a first part (1) affording a bore (3) and a second part (2) comprising a sleeve (5) and a drive flange (6). The sleeve (5) fits in the bore (3) and contains an insert (8) with collars (9,10) between which is defined a chamber (4) for the reception of oil under pressure to expand the sleeve into frictional engagement with the wall of the bore (3) for torque transmission. There may be a pressure release valve response to relative movement between the first and second coupling parts to release the coupling in case of overload.

  • Patent number: 4832659
    Abstract: A phase adjusting mechanism in which input and output shafts, rotatable at like speeds and directions, are positively intercoupled by helical spline members constructed and arranged so that a female spline member is shiftable axially relative to a male spline member to counter rotate the shafts through a limited range of relative adjustability and in which support of adjacent opposed ends of the shafts is effected by an internal backbone support extending coaxially between the shafts to provide thrust and radial bearing support therefor. Adjustment members for shifting the spline members is provided along with an indicator mechanism for indicating the degree of shaft phase adjustment. A locking mechanism is provided for securing the adjustment mechanism in selected positions.

  • Patent number: 4804288
    Abstract: Two shafts 12, 14 are secured axially with bolts 58 through flanges 22 and 32. Coupling 42 is splined to the shafts and resists bending by interaction of bearing surfaces 46, 44, 48 and 50. Threads 66 on one end of the shaft and an inwardly extending flange 68 on the coupling provide a means for removing a shaft without placing axial loading on bearing 18. Either shaft may be removed while leaving the coupling 42 in place to protect the bearing compartment. Axial loading is taken by bolts 58, torque loading by splines 30, 40 and bending moment taken by the interacting surfaces.

  • Patent number: 4765769
    Abstract: The present invention relates to an apparatus for mounting auxiliary components such as a seat, a camera platform or the like at or near the bearings which support the dolly or carriage wheels or articulated legs. The present includes at least one cap member and a receiving tube. Each cap member is arranged so as to transfer any force placed on the receiving tube directly onto the vehicle frame rather than the bearings associated with the leg king pin system. The cap members also serve to exclude contaminants from the bearing means of the leg king pin system. Rotation of the leg king pin driveshaft is not impeded by the receiving tube. One embodiment of the present invention also includes a groove in one of the cap members to permit the locking of the leg locking pin in the disengaged position.

  • Patent number: 4637412
    Abstract: A device for storing dental floss and paying the floss out is disclosed, which device provides three separately-usable strips of dental floss for use to floss teeth. The three strips form a U-shaped loop, and are tightened, or tensioned, for use by a tensioning means made up of an axle with a slot formed at each end, through which portions of the first and third strips of floss pass, which first and third strips are parallel to each other. The axle is mounted for conjoint rotation with a ratchet wheel which is allowed rotation in only one direction by an associated pawl. A thumb wheel mounted for rotation with the ratchet wheel and axle is rotatable by the user of the device to continually tension the strips of floss for use, which rotation of the thumb wheel is easily done by one hand of the user.
