Definitions

  • the present invention relates to a boss structure of an impeller of a blower and to an impeller of a blower equipped with the boss structure and particularly to a boss structure to which a rotating shaft of a motor that drives an impeller of a blower to rotate is pivotally attached and to an impeller equipped with the boss structure.
  • Patent Document 1 JP-A No. 2003-269382
  • a boss structure is a boss structure to which a rotating shaft of a motor that drives an impeller of a blower to rotate is pivotally attached, the boss structure comprising: a hub that includes a cylindrical portion that extends in the rotating shaft direction; a vibration isolation member that sandwiches the cylindrical portion from both sides in a radial direction; a first boss that supports a portion of the vibration isolation member that contacts one radial direction side of the cylindrical portion, the rotating shaft being pivotally attached to the first boss; and a second boss that supports a portion of the vibration isolation member that contacts the other radial direction side of the cylindrical portion, the second boss integrally rotating with the first boss.
  • an elastic material such as a rubber material is used as the material of the vibration isolation member.
  • both radial direction sides of the cylindrical portion of the hub contact the vibration isolation member and the vibration isolation member is sandwiched from both sides in the radial direction by the first boss and the second boss, so, for example, in comparison to a conventional boss structure where the hub is simply fixedly attached to the outer peripheral portion of the boss via the vibration isolation member, the amount of displacement of the vibration isolation member in the radial direction with respect to an external force becomes about half.
  • a boss structure according to a second aspect of the present invention is the boss structure according to the first aspect of the present invention, wherein the second boss is integrally molded with the first boss.
  • the first boss and the second boss are integrally molded, so the number of parts configuring the boss structure can be reduced.
  • a boss structure according to a third aspect of the present invention is the boss structure according to the first or second aspect of the present invention, wherein the first boss and the second boss form a space that houses the vibration isolation member.
  • the first boss and the second boss form a space that houses the vibration isolation member, so, for example, in a case where the vibration isolation member comprises a rubber material, the rubber material can, in a state where the cylindrical portion of the hub has been disposed in a predetermined position in this space, be injected into or fill the space and be vulcanization-molded, and in a case where the vibration isolation member comprises a resin material that has elasticity, the resin material can, in a state where the cylindrical portion of the hub has been disposed in a predetermined position in this space, be injected into or fill the space and be insert-molded.
  • the vibration isolation member comprises a rubber material
  • the vibration isolation member comprises a resin material that has elasticity
  • the material configuring the vibration isolation member can be injected into or fill the space that the first boss and the second boss form, such that the vibration isolation member can be integrally molded with the first boss, the second boss and the hub, so manufacture is easy.
  • a boss structure according to a fourth aspect of the present invention is the boss structure according to the third aspect of the present invention, wherein an opening that allows the space to be communicated with the outside is formed in the first boss and/or in the second boss.
  • the opening that allows the space that houses the vibration isolation member to communicate with the outside is formed, such that when the vibration isolation member is to be integrally molded with the first boss, the second boss and the hub, the material configuring the vibration isolation member can be injected into or fill the space from the outside, so manufacture becomes even easier.
  • An impeller of a blower according to a fifth aspect of the present invention comprises the boss structure according to any of the first to fourth aspects of the invention and an impeller body that is integrated with the hub or is fixed to the hub.
  • the impeller is equipped with the boss structure where both radial direction sides of the cylindrical portion of the hub contact the vibration isolation member and where the vibration isolation member is sandwiched from both sides in the radial direction by the first boss and the second boss, so deformation of the vibration isolation member in the radial direction with respect to an external force can be reduced, and the strength of the impeller can be improved.

  • the boss structure 1 of the present embodiment (the same is also true of the impeller 100 of a blower equipped with this boss structure 1) has the following characteristics. (A)
  • both radial direction sides of the cylindrical portion 12 of the hub 10 contact the vibration isolation member 20 and the vibration isolation member 20 is sandwiched from both sides in the radial direction by the first boss 31 and the second boss 32, so, for example, in comparison to a conventional boss structure where the hub is simply fixedly attached to the outer peripheral portion of the boss via the vibration isolation member, the amount of displacement of the vibration isolation member 20 in the radial direction with respect to an external force becomes about half, and thus deformation of the vibration isolation member 20 in the radial direction with respect to an external force can be reduced, so the strength of the impeller 100 can be improved.
