Definitions

  • the present invention relates generally to scroll type compressors and more specifically to scroll type compressors incorporating a fluid brake operative to resist and impede reverse movement of the orbiting scroll member.
  • scroll compressors depend upon a seal created between opposed flank surfaces of the wraps to define successive chambers for compression, suction and discharge valves are generally not required.
  • suction and discharge valves are generally not required.
  • the gas in the pressurized chambers and/or backflow of compressed gas from the discharge chamber to effect a reverse orbital movement of the orbiting scroll member and associated drive shaft. This reverse movement often generates objectionable noise or rumble.
  • This reverse operation may result in overheating of the compressor and/or other damage to the apparatus. Additionally, in some situations, such as a blocked condenser fan, it is possible for the discharge pressure to increase sufficiently to stall the drive motor and effect a reverse rotation thereof. As the orbiting scroll rotates in the reverse direction, the discharge pressure will decrease to a point where the motor again is able to overcome this pressure head and rotate the scroll member in the "forward" direction. However, the discharge pressure will now increase to a point where the cycle is repeated. Such cycling may also result in damage to the compressor and/or associated apparatus.
  • the present invention overcomes these problems by incorporating one-way drive means, such as a one-way clutch, coupled between the drive shaft and a paddle disposed in the compressor oil sump.
  • one-way drive means such as a one-way clutch
  • the clutch When the drive shaft is rotating in the desired direction the clutch is inoperative to drive the paddle, but when rotation reverses the drive shaft rotates the paddle in the sump so that it acts like a fluid brake to resist and impede movement of the orbiting scroll member in a reverse direction, thereby eliminating the objectionable noise generated upon shut down of the compressor.
  • this fluid brake operates to resist damage to the motor and/or compressor resulting from a reversing of single phase motors as well as resisting the cyclical reversing resulting from a blocked or failed condenser fan.
  • the brake is passive in that it does not create any load during normal operation of the compressor.
  • the present invention is an improvement over the concept disclosed in U.S. Letters Patent No. 4,998,864, the disclosure of which is hereby incorporated herein by reference, wherein the drive shaft is connected to a rigid structure by a one-way clutch to prevent reverse rotation. Braking with the present design is much gentler, thereby significantly increasing the life of the one-way clutch mechanism.
  • the present shield incorporates a generally flat circular disk or flange positioned in close proximity to the lower end of the rotor which serves to reduce return flow of oil to the area of the rotating rotor and/or counterweight but still enables some circulation thereof, which thereby increases the circulation of oil across the adjacent motor stator end turns.
  • this improved shield has resulted in improved cooling of the stator end turns without any substantial effect on the overall operating efficiency of the compressor.
  • a motor stator 28 which is generally square in cross-section but with the corners rounded off is press fitted into shell 12.
  • the flats between the rounded corners on the stator provide passageways between the stator and shell, which facilitate the return flow of lubricant from the top of the shell to the bottom.
  • a drive shaft or crankshaft 30 having an eccentric crank pin 32 at the upper end thereof is rotatably journaled in a bearing 34 in main bearing housing 24 and a second bearing 36 in lower bearing housing 26.
  • Crankshaft 30 has at the lower end a relatively large diameter concentric bore 38 which communicates with a radially outwardly inclined smaller diameter bore 40 extending upwardly therefrom to the top of the crakshaft. Disposed within bore 38 is a stirrer 42.
  • the lower portion of the interior shell 12 defines an oil sump 43 which is filled with lubricating oil to a level slightly above the lower end of rotor 46, and bore 38 acts as a pump to pump lubricating fluid up the crankshaft 30 and into passageway 40 and ultimately to all of the various portions of the compressor which require lubrication.
  • Crankshaft 30 is rotatively driven by an electric motor including stator 28, windings 44 passing therethrough and a rotor 46 press fitted on the crankshaft 30 and having upper and lower counterweights 48 and 50, respectively.
  • main bearing housing 24 The upper surface of main bearing housing 24 is provided with a flat thrust bearing surface 53 on which is disposed an orbiting scroll 54 having the usual spiral vane or wrap 56 on the upper surface thereof.
  • orbiting scroll 54 Projecting downwardly from the lower surface of orbiting scroll 54 is a cylindrical hub having a journal bearing 58 therein and in which is rotatively disposed a drive bushing 60 having an inner bore 62 in which crank pin 32 is drivingly disposed.
  • Crank pin 32 has a flat on one surface which drivingly engages a flat surface (not shown) formed in a portion of bore 62 to provide a radially compliant driving arrangement, such as shown in assignee's U.S. Letters Patent 4,877,382, the disclosure of which is hereby incorporated herein by reference.
  • a non-orbiting scroll member 64 is also provided having a wrap 66 positioned in meshing engagement with wrap 56 of scroll 54.
  • Non-orbiting scroll 64 has a centrally disposed discharge passage 75 which communicates with an upwardly open recess 77 which in turn is in fluid communication with a discharge muffler chamber 79 defined by cap 14 and partition 22.
  • An annular recess 81 is also formed in non-orbiting scroll 64 within which is disposed a seal assembly 83.
  • Recesses 77 and 81 and seal assembly 83 cooperate to define axial pressure biasing chambers which receive pressurized fluid being compressed by wraps 56 and 66 so as to exert an axial biasing force on non-orbiting scroll member 64 to thereby urge the tips of respective wraps 56, 66 into sealing engagement with the opposed end plate surfaces.
  • Seal assembly 83 is preferably of the type described in greater detail in assignee's copending application Serial No. 591,454, filed October 1, 1990, entitled “Scroll Machine with Floating Seal", the disclosure of which is hereby incorporated herein by reference.
  • Scroll member 64 is designed to be mounted to bearing housing 24 in a suitable manner such as disclosed in the aforementioned U.S. Patent No. 4,877,382 or as disclosed in assignee's copending application Serial No. 591,444 filed October 1, 1990 and entitled “Non-Orbiting Scroll Mounting Arrangement For Scroll Machine", the disclosure of which is hereby incorporated herein by reference.
  • hub 88 has a relatively short integral horizontal flange 103 extending radially outwardly from the upper periphery thereof between blades 86, which can act as a rotor shield of the type described in the aforementioned application Serial No. 591,442.
  • clutch assembly 94 includes an outer housing 104, formed of steel or the like, within which are disposed a plurality of circumferentially spaced roller pins 106 rotatably supported within acally extending cavities defined by housing 104, which is channel-shaped in cross-section, ad a plastic retainer 108 comprising spaced annular end portions 110 and integral axially extending portions 112 disposed between each roller 106.
  • Each of the cavities is substantially identical, extending over the full length of each pin 106, and includes a rear wall 114 formed in housing 104 which tapers in a circumferential direction from one end wherein it is positioned at a maximum radial distance from the axis of rotation of shaft 30 to the opposite end wherein it is positioned at a minimum radial distance therefrom. At the maximum radial distance location the distance between shaft 30 and wall 114 will be equal to or slightly greater than the diameter of each pin 106 and at the minimum radial distance location it is less than the diameter of each pin.
  • a generally C-shaped leaf spring 116 is also disposed within each cavity which operates to urge each pin 106 toward the radially shallower end thereof. Each spring 116 is supported by a radial projection 118 on each portion 112 of retainer 108.
  • FIGs 6 through 8 Variations of the paddle are illustrated in Figures 6 through 8.
  • Figure 6 there is illustrated a paddle which is in all respects identical to paddle 84 except that it has three relatively flat blades 100 rather than merely two blades 200.
  • Figure 7 there is illustrated a three bladed patent similar to that of Figure 6 except that in the Figure 7 version each blade 300 is slightly curved in the plane shown to thereby alter the breaking characteristics of the device.
  • Figure 8 there is illustrated a paddle which can have any number of blades but which instead of being flat in cross-section is curved in the manner shown at 350.
  • FIGs 9 and 10 there are illustrated two additional alternative embodiments of the paddle in which the paddle is formed from a polymeric material, such as glass filled nylon, and in which the paddle is affixed to the shaft by integral fingers.
  • a paddle 400 having two or more relatively flat plates 402 integrally formed with a hub 404 having extending outwardly from the upper periphery thereof a generally circular flange 406 which can act as a rotor shield as described above.
  • Paddle 400 is provided with a steel insert 90 and a one-way clutch assembly 94 in the same manner and for the same function as in the preceding embodiments.
  • Figure 9 is not a 180 degree section and that on the right-had portion the section line passes through the paddle, whereas in the left-hand portion the section line passes through a non-blade portion of the paddle.
  • Extending downwardly and inwardly from the center of hub 88 are a plurality (e.g., eight or more) integrally formed resilient fingers 108 which are disposed in a groove 110 in shaft 30. The interaction of fingers 108 and groove 110 serves to axially locate the paddle on the shaft.
