Definitions

  • the present disclosure relates to a scroll compressor used for, in particular, an air conditioner, a water heater, or a freezing machine of a refrigerator or the like.
  • Japanese Patent No. 4892238 discloses a scroll compressor used for an air conditioner or the like.
  • a back pressure region is provided on an anti-wrap surface of an orbiting scroll end plate, and an orbiting scroll is pressed against a fixed scroll, thereby suppressing turning of the orbiting scroll and reducing leakage loss to improve theoretical efficiency and capability of cooling and heating.
  • KR 100 414 123 B1 discloses a friction loss reducing device for a scroll compressor.
  • a back pressure region is formed on an anti-wrap surface of an orbiting scroll end plate, and an orbiting scroll is pressed against a fixed scroll.
  • the wrap side of an orbiting bearing of the orbiting scroll is closed by an end plate, and the crank shaft side is opened.
  • the orbiting bearing of the orbiting scroll has a tapered shape of which diameter gradually increases toward an open side of the orbiting bearing, or an eccentric shaft inserted in the orbiting bearing has a tapered shape of which diameter gradually decreases toward the open side of the orbiting bearing.
  • Main bearing 30 that supports fixed scroll 11 and orbiting scroll 12 is provided below fixed scroll 11 and orbiting scroll 12.
  • Main bearing 30 includes bearing 31 that rotatably supports rotary shaft 13, and boss housing 32.
  • Main bearing 30 is fixed to hermetic container 1 by welding, shrink fit, or the like.
  • Fixed scroll 11 includes fixed scroll end plate 11a having a disk shape, fixed spiral wrap 11b having a spiral shape and erecting from fixed scroll end plate 11a, and outer peripheral wall portion 11c erecting so as to surround the circumference of fixed spiral wrap 11b.
  • Discharge port 14 is provided substantially at a center portion of fixed scroll end plate 11a.
  • Orbiting scroll 12 includes orbiting scroll end plate 12a having a disk shape, orbiting spiral wrap 12b erecting from one surface (wrap-side end surface) of orbiting scroll end plate 12a, and cylindrical boss portion 12c formed on the other surface (anti-wrap-side end surface) of orbiting scroll end plate 12a.
  • the other surface of orbiting scroll end plate 12a is a surface opposite to the wrap-side end surface of orbiting scroll end plate 12a.
  • Fixed spiral wrap 11b of fixed scroll 11 and orbiting spiral wrap 12b of orbiting scroll 12 mesh with each other, and a plurality of compression chambers 15 is formed between fixed spiral wrap 11b and orbiting spiral wrap 12b.
  • Boss portion 12c is formed substantially at the center of orbiting scroll end plate 12a. Boss portion 12c is accommodated in boss housing 32 with eccentric shaft 13a inserted in boss portion 12c.
  • Fixed scroll 11 is fixed to main bearing 30 by outer peripheral wall 11c using a plurality of bolts (not shown). Meanwhile, the movement of orbiting scroll 12 with respect to fixed scroll 11 is restricted by spin-restraining member 17 such as an Oldham ring. Spin-restraining member 17 that restrains spinning of orbiting scroll 12 is provided between fixed scroll 11 and main bearing 30. This makes orbiting scroll 12 to orbit without spinning with respect to fixed scroll 11 as eccentric shaft 13a of rotary shaft 13 orbits.
  • Oil storage part 4 that stores lubricating oil is formed at the bottom of hermetic container 1.
  • Lower end 13b of rotary shaft 13 is rotatably supported by sub-bearing 18 disposed at the lower portion of hermetic container 1.
  • Oil pump 5 of a displacement type is provided at the lower end of rotary shaft 13. Oil pump 5 is disposed so as a suction port of oil pump 5 to be in oil storage part 4. Oil pump 5 is driven by rotary shaft 13 and reliably sucks up lubricating oil in oil storage part 4 provided at the bottom of hermetic container 1 at any pressure condition and operating speed, which eliminates concern about loss of oil.
  • the refrigerant suctioned from refrigerant suction pipe 2 is introduced from suction port 15a to compression chamber 15.
  • Compression chamber 15 moves from the outer peripheral side toward the central portion while reducing its volume.
  • the refrigerant that has reached a predetermined pressure in compression chamber 15 is discharged to discharge chamber 6 from discharge port 14 provided at the central portion of fixed scroll 11.
  • Discharge port 14 is provided with a discharge reed valve (not shown).
  • the refrigerant that has reached a predetermined pressure in compression chamber 15 pushes open the discharge reed valve and is discharged to discharge chamber 6.
  • the refrigerant discharged to discharge chamber 6 is led out to the upper portion of hermetic container 1, and is then discharged through refrigerant discharge pipe 3.
  • second oil lead-out hole 62 of orbiting scroll 12 intermittently provides communication between intermediate-pressure region B and compression chamber 15. This introduces the intermediate pressure in compression chamber 15 to intermediate-pressure region B, and orbiting scroll 12 can be pressed against fixed scroll 11 with a minimum necessary load under various operating conditions. Accordingly, separation of orbiting scroll 12 from fixed scroll 11 can be prevented while reducing friction loss of the compressor, and thereby the airtightness of compression chamber 15 can be improved.
  • Figs. 3A to 3D are views illustrating the volumetric change of the compression chamber caused by the orbiting motion in the scroll compressor according to the present exemplary embodiment, where the views each illustrates a meshing state of orbiting scroll 12 and fixed scroll 11 looking from the back surface of orbiting scroll 12.
  • Fig. 3B illustrates a state in which the rotation is advanced by 90 degrees from Fig. 3A
  • Fig. 3C illustrates a state in which the rotation is further advanced by 90 degrees from Fig. 3B
  • Fig. 3D illustrates a state in which the rotation is further advanced by 90 degrees from Fig. 3C .
  • first compression chamber 15A is formed on an outer wall side of orbiting spiral wrap 12b
  • second compression chamber 15B is formed on an inner wall side of orbiting spiral wrap 12b.
  • the maximum angle at which rotary shaft 13 can tilt is defined by the clearance between main bearing 30 and rotary shaft 13 and the clearance between sub-bearing 18 and rotary shaft 13 illustrated in Figs. 4A and 4B .
  • Figs. 4A and 4B illustrate the rotating state of rotary shaft 13 that makes the orbiting scroll orbit.
  • Fig. 4A illustrates a state with no compression load
  • Fig. 4B illustrates a state with a compression load.
  • eccentric shaft 13a located at an end of rotary shaft 13 rotates while pushing orbiting bearing 13d of orbiting scroll 12.
  • the back pressure acting on the anti-wrap surface of orbiting scroll end plate 12a of orbiting scroll 12 keeps orbiting scroll 12 pressed against fixed scroll 11.
  • the tapered shape of orbiting bearing 13d or eccentric shaft 13a may include a straight line, a continuous curve, or a combination thereof. This further distributes surface pressure to moderate a local surface pressure, and a scroll compressor with further lower input and higher efficiency can be provided.
  • the scroll compressor includes compression mechanism unit 10 that compresses the refrigerant, motor mechanism unit 20 that drives compression mechanism unit 10, and hermetic container 1 that accommodates compression mechanism unit 10 and motor mechanism unit 20.
  • Compression mechanism unit 10 includes fixed scroll 11, orbiting scroll 12, and rotary shaft 13 that drives orbiting scroll 12 to orbit.
  • Fixed scroll 11 includes fixed scroll end plate 11a having a disk shape and fixed spiral wrap 11b erecting from fixed scroll end plate 11a
  • orbiting scroll 12 includes orbiting scroll end plate 12a having a disk shape and orbiting spiral wrap 12b erecting from the wrap-side end surface of orbiting scroll end plate 12a.
  • Compression chamber 15 includes first compression chamber 15A formed on the outer wall side of the orbiting spiral wrap and second compression chamber 15B formed on the inner wall side of orbiting spiral wrap 12b.
  • Orbiting scroll 12 is pressed against fixed scroll 11 by back pressure created on the anti-wrap surface side of orbiting scroll end plate 12a.
  • the wrap side of orbiting bearing 13d of orbiting scroll 12 is closed by an end plate, and eccentric shaft 13a side of rotary shaft 13 is opened.
  • the tapered shape of orbiting bearing 13d or eccentric shaft 13a shortens the distance between the point of effort, when the side surface of the wrap of the orbiting scroll receives a tangential gas load, and the point at which the orbiting bearing receives the reaction force, and thereby the turning moment that causes orbiting scroll 12 to turn can be suppressed.
  • the behavior of orbiting scroll 12 easily becomes unstable due to, for example, first compression chamber 15A having a larger suction volume than second compression chamber 15B as in the present exemplary embodiment, the behavior of orbiting scroll 12 can be stabilized more effectively.
  • the tapered shape of orbiting bearing 13d or eccentric shaft 13a starts from a midway of the sliding surface between orbiting bearing 13d and eccentric shaft 13a. This prevents the surface pressure from locally becoming large at the lower end on the opened side of orbiting bearing 13d (second end 13db), and promotes formation of an oil film between the sliding portions.
  • orbiting bearing 13d has a tapered shape of which diameter increases toward the open side of orbiting bearing 13d.
  • the angle ⁇ between the tapered shape and the axis of orbiting bearing 13d is set so as to satisfy the following relational expression, where L is the distance between the upper end of orbiting bearing 13d (first end 13da) and the start point of the taper, d is the diameter of the eccentric shaft, and D is the diameter of the orbiting bearing.
