A nut holding member fixed to the second tab has an engaging piece. The engaging piece causes the nut, which has not been screwed onto the bolt, to be held on the fastening axis. A cover held by the nut holding member covers at least the engaging piece around the nut.

  • Publication number: 20090003930
    Abstract: The present invention provides an assembly for attaching a hub to a shaft. The hub, which may be a portion of a gear, pulley, chain sprocket or other power carrying device, includes a collar or annular wall having two axially extending relief cuts on opposite sides of a shaft opening, which define a pair of opposed projections or clamp members. The clamp members include opposed flats on the inside of the shaft opening which engage complementarily configured flats on the shaft. A threaded fastener such as a bolt extends through smooth radial bores in one clamp member and the shaft and into a complementarily threaded bore in the other clamp member. The internal flats of the hub include opposed arcuate, axially extending reliefs. The outside surface of the hub proximate the smooth bore defines a chordal surface which the bolt engages.

  • Patent number: 7390139
    Abstract: A minimal volume boss may be formed as key and keyway assembly defining a shaft along the interface between the two pieces. A threaded fastener may be threaded into the shaft to lock the two pieces together. Because the key can have minimal volume, the cavitation spot opposite the key, typically formed during molding can be eliminated on fine surfaces. By properly keying the pieces, rotation between parts can also be eliminated. This helps automated torque sensing tools read and apply the proper torque in automated assembly.

  • Patent number: 7334495
    Abstract: There is provided a resin gear 1 capable of improving the strength of a key receiving portion, which is engageable with a key of a driving shaft, to prevent the key receiving portion from being broken by external force applied during rotation. In the resin gear 1, an outside rim 6 is connected to an inside hub 4 by a web 7 in radial directions. On the side of one end of the hub 4, a key receiving portion 10 for engaging a key of a driving shaft 2 is formed. The key receiving portion 10 has a side wall 1 for preventing relative rotation of the key 8 to the hub 4, and a bottom wall 12 for allowing the key 8 and hub 4 from being positioned in directions parallel to the driving shaft 2.

    Abstract: Apparatus and method for rotationally immobilizing a hub on a rotatable shaft. A portion of the shaft is cylindrical and has a first diameter. The hub has a cylindrical axial bore having a second diameter larger than the diameter of the shaft. At least one axially-extending keyway is provided in the surface of the shaft. When the shaft is inserted into the hub bore, the hub is free to rotate upon the shaft. To immobilize the hub rotationally with respect to the shaft, at least one tapered key having a height greater than the maximum depth of the at least one keyway is inserted axially into the at least one keyway. Preferably, the at least one key is inserted along the at least one keyway to a point at which the maximum height of the at least one key is positioned at the axial midpoint of the hub bore.

  • Patent number: 6851886
    Abstract: A knee joint assembly for an agricultural implement or a vehicle includes a relatively short knee casting with an apertured end of rectangular cross section which is inserted in a mating steel knee tube. The apertures in the casting end align with beveled apertures in the side walls of the knee tube. Steel pins of length approximately equal to the spacing of the side walls are pressed into the casting through the beveled apertures. Groove welds then secure the steel pins to the knee tube. The casting is relatively small and does not require any welding. Inexpensive ductile iron and common steel tubes can be used for most or all of the assemblies on a machine. The apertured end of the casting includes concave walls to accommodate knee tube concavity and weld flash on the inside of the knee tube.
