Lock Type Patents (Class 384/217)
  • Patent number: 8152379
    Abstract: A bearing device include: (a) a bearing supporting a shaft, and having (a-1) a tubular body portion in which the shaft is rotatably received and (a-2) a radially projecting portion that projects from the tubular body portion outwardly in a radial direction of the tubular body portion; and (b) a bearing receiver plate having (b-1) a receiver hole in which the tubular body portion of the bearing is received, and (b-2) a cutout which extends from the receiver hole and which has an opening that opens outwardly of the bearing receiver plate, such that the bearing can be introduced into the receiver hole via the cutout. The bearing receiver plate and the radially projecting portion of the bearing cooperate with each other to establish (i) a rotation preventer preventing rotation of the bearing relative to the bearing receiver plate and (ii) a backlash reducer reducing play of the bearing relative to the bearing receiver plate. Also disclosed is an image recording apparatus including the bearing device.

  • Patent number: 6376952
    Abstract: A floating bearing system comprising a bearing supported in a clearance fit within a bearing bracket, for example for use in fractional horsepower shaded pole type electric motors. The bearing system is self aligning, to compensate for deviations in the axial alignment of the rotor shaft. A rotation lock restrains the bearing against rotation within the bearing receptacle while allowing the bearing to settle into proper alignment with the rotor shaft by automatically shifting the pitch of the axis of the bearing. In the preferred embodiment the bracket is composed of an engineering plastic and the bearing is composed of a high performance plastic polymer, so that the bearing system is non-lubricating. In the preferred embodiment the bearing bracket is provided with retaining fingers which hold the bearing in place during the assembly and working life of the motor.

  • Patent number: 4887331
    Abstract: A pivot bushing comprises a tubular body defining a bore adapted to receive a pivot pin and includes a radially enlarged peripheral flange and at least one resilient finger extending radially outwardly from one end of the body and facing toward the peripheral flange. The free end of each finger is axially spaced from the annular surface of the peripheral flange so as to receive an apertured support panel therebetween. The tubular body also includes a radially expanded shoulder adjacent the peripheral flange and having a periphery formed with a cone surface dimensioned to matingly engage with the aperture in the support panel in a self-centering manner. The components are unitarily formed from a siingle bearing body.
