Definitions

  • the present invention relates to a scroll compressor provided with a balance weight that is integrated with a drive bush by means of shrink fitting.
  • a balance weight is provided in a drive shaft system.
  • the balance weight is integrally provided on, for example, a drive bush that is for driving an orbiting scroll and that is mounted to a crank pin provided at an end of the drive shaft, on the drive shaft, on an end surface of a motor rotor that is joined with the drive shaft, or the like.
  • Patent Literature 1 discloses a system in which a balance weight is integrally provided on a drive bush
  • Patent Literature 2 discloses a system in which a balance weight is integrally provided on a crank-pin portion of a drive shaft and the balance weight is also integrally provided on an end surface of a motor rotor that is joined with the drive shaft.
  • the usual method is to integrally mold the two or to shrink fit a fitting portion of the balance weight to the drive bush.
  • WO 2012/144224 A1 & EP 2 713 053 A1 disclose a scroll compressor according to the preamble of claim 1. Another scroll compressor is disclosed in JP 2007-327438 A .
  • the present invention has been conceived in light of the above-described circumstances, and an object thereof is to provide a scroll compressor with which it is possible to enhance the strength by which a balance weight is shrink fitted to a drive bush, where the size of the balance weight is increased in correspondence with an increase in the rotational speed of a compressor, and with which it is also possible to ensure a space for installing and accommodating the balance weight.
  • a scroll compressor of the present invention is defined according to claim 1.
  • a scroll compressor is a scroll compressor including a crank pin that is provided at an end of a drive shaft that is supported about a shaft by a bearing member; and an orbiting scroll that is joined with the crank pin via a drive bush so that the orbiting scroll can be driven in a revolving orbital manner, wherein a balance weight is integrally provided on the drive bush by means of shrink fitting, and l/d ⁇ 0.25 and D/d ⁇ 1.4 are satisfied, assuming that, in a shrink fitted portion, an axial-direction length of a fitting portion of the balance weight to be shrink fitted to a drive bush is 1, that an inner diameter is d, and that an outer diameter is D.
  • the balance weight is provided by being shrink fitted to the drive bush and l/d ⁇ 0.25 and D/d ⁇ 1.4 are satisfied, assuming that, in the shrink fitted portion, the axial-direction length of the fitting portion of the balance weight to be shrink fitted to the drive bush is 1, that the inner diameter is d, and that the outer diameter is D, by setting the axial-direction length 1 and the outer diameter D to be sufficiently large relative to the inner diameter d of the fitting portion of the balance weight to be shrink fitted to the drive bush, it is possible to increase the shrink fitting strength by alleviating the contact pressure at the shrink fitted portion or stress due to the centrifugal force or the like, and, when increasing the rotational speed of the scroll compressor, even if the size of the balance weight is increased and the centrifugal force thereof is increased, it is possible to prevent damage or the like due to a lack of strength in the shrink fitted portion.
  • the balance weight is provided with a weight portion in an arc-shape at an outer circumferential portion of the fitting portion to be shrink fitted to the drive bush, and the weight portion may have a shape that is extended in an axial direction from both surfaces of the fitting portion.
  • the balance weight because the arc-shaped weight portion is provided at an outer circumferential portion of the fitting portion to be shrink fitted to the drive bush and the weight portion has a shape that is extended in the axial direction from both surfaces of the fitting portion, by employing the balance weight having a T-shaped cross-section, it is possible to decrease the distance from the fitting portion to the center-of-gravity of the weight portion as compared with the case of an L-shaped balance weight, it is possible to decrease a bending moment that acts on the fitting portion (shrink fitted portion) due to the centrifugal force exerted by the balance weight, thus allowing the stress thereof to be alleviated, and, moreover, it is possible to increase the size of the balance weight without expanding it in a radial direction. Therefore, it is possible to sufficiently increase the size of the balance weight so as to match the increase in the unbalanced load or the like, and it is also possible to contribute to increasing the rotational speed of the scroll compressor by further increasing the shrink fitting strength.
  • the bearing member is provided with a concave portion that receives a weight portion that is extended from a surface of the fitting portion of the balance weight away from the orbiting scroll.
  • the bearing member is provided with the concave portion that receives the weight portion that is extended from the surface of the fitting portion of the balance weight away from the orbiting scroll, even if a balance weight having a T-shaped cross-section whose weight portion is extended from a surface of the fitting portion away from the orbiting scroll is employed as the balance weight, it is possible to accommodate the weight portion that is extended from the surface away from the orbiting scroll in the concave portion of the bearing member and to rotate the weight portion in the interior thereof. Therefore, even if the size of the balance weight is sufficiently increased without increasing the size of the scroll compressor, it is possible to ensure space to accommodate it and to contribute to increasing the rotational speed of the scroll compressor.
  • the balance weight may be provided with a cut-out portion at a distal end of a weight portion at an outer circumferential side thereof, which is extended from an orbiting-scroll-side surface of the fitting portion, interference with a thrust bearing portion of the orbiting scroll, provided in the bearing member, may be avoided by means of the cut-out portion, and thus, the weight portion may be extended toward the orbiting scroll.
  • the cut-out portion is provided at the distal end of the weight portion at the outer circumferential side thereof, which is extended from the surface of the fitting portion on the orbiting scroll side, and, because the weight portion is extended toward the orbiting scroll by avoiding, by means of the cut-out portion, interference with the thrust bearing portion of the orbiting scroll, provided in the bearing member, it is possible to increase the size of the balance weight by an amount corresponding to the amount of the extension toward the orbiting scroll by providing the cut-out portion at the distal end of the weight portion at the outer circumferential side thereof and by avoiding interference with the thrust bearing portion. Therefore, by installing and accommodating the larger balance weight without increasing the size of the scroll compressor, it is possible to contribute to increasing the rotational speed of the scroll compressor by satisfactorily canceling out the unbalanced load or the like.
  • the present invention by setting the axial-direction length 1 and the outer diameter D to be sufficiently large relative to the inner diameter d of a fitting portion of a balance weight to be shrink fitted to a drive bush, it is possible to increase the shrink fitting strength by alleviating the contact pressure at a shrink fitted portion or stress due to the centrifugal force or the like, and, when increasing the rotational speed of a scroll compressor, even if the size of the balance weight is increased and the centrifugal force thereof is increased, it is possible to prevent damage or the like due to a lack of strength in the shrink fitted portion; therefore, it is possible to enhance the capacity of the scroll compressor by realizing high rotational speed in the scroll compressor by reliably canceling out or adjusting, by means of the balance weight, the unbalanced load and the tooth-surface load that are increased by increasing the rotational speed of the orbiting scroll.
