Abstract
A compressor includes a thrust bearing, a first member and a second member that face to each other while sandwiching the thrust bearing therebetween, and a release portion that allows deformation of an outer region of one of races of the thrust bearing.
Description
- This application is based upon and claims the benefit of priority from the prior Japanese Patent Applications No. 2005-0321101, filed on Nov. 4, 2005; the entire contents of which are incorporated herein by reference.
- 1. Field of the Invention
- The present invention relates to a compressor, and, more particularly, to a compressor useable in a refrigeration cycle of a vehicular air conditioner or the like to compress refrigerant.
- 2. Description of the Related Art
- As a conventional compressor, for example, there is a wobble plate type variable displacement compressor disclosed in Japanese Patent Application Laid-Open No. 2000-320455. The wobble plate type variable displacement compressor includes a shaft, a rotating base for integral rotation with the shaft, a wobble plate that is rotatably attached to the rotating base via a radial bearing and a thrust bearing, and pistons connected to an outer region of the wobble plate via pairs of hemispherical-shaped shoes. When the rotating base integrally rotates with the shaft, the wobble plate wobbles in a manner corresponding to the inclination angle of the rotating base, so that the pistons reciprocate.
- The wobble plate does not rotate rapidly due to the friction with the shoes. Accordingly, the wobble plate type compressor has an advantage that the rotation moment (the torque) is small and the friction between the shoes and the wobble plate is low, compared to a swash plate type compressor in which a swash plate integrally rotates with a shaft.
- In the wobble plate type compressor, a compression reaction force from the pistons is applied to an area around the upper dead center of the wobble plate. The compression reaction force is set off from the center of the shaft (the center of the wobble plate) so that the wobble plate is pressed in such a manner that the wobble plate inclines with respect to the rotating base. Accordingly, the strong force is applied to an outer region of the thrust bearing located between the wobble plate and the rotating base. This force causes the outer region of rolling elements of the thrust baring to be subjected to excessive wear.
- Japanese Patent Application Laid-Open No. 2003-328931 suggests locating a thrust bearing on an axial line of the pistons to receive the compression reaction force from the pistons. This location requires a large thrust bearing so that a flange formed on the rotating base and a flange formed on the wobble plate that sandwich the larger thrust bearing also have a large size.
- The present invention was developed based on such a problem of the related art and provides a compressor in which damage of an outer region of a thrust bearing, caused by a compression reaction force, can be prevented without enlarging the size.
- The first aspect of the present invention is a compressor including a thrust bearing having a pair of races; a first member and a second member sandwiching the thrust bearing therebetween; and a release portion that allows flexing of an outer region of one of races of the thrust bearing.
- The second aspect of the present invention is a compressor including a thrust bearing; a first member and a second member sandwiching the thrust bearing therebetween; a first thrust receiving face formed on the first member and receiving the thrust bearing; and a second thrust receiving face formed on the second member and receiving the thrust bearing, at least one of the first thrust receiving face and second thrust receiving face being out of contact with an outer region of the thrust bearing.
- The third aspect of the present invention is a compressor including a shaft; a rotating base configured to rotate with the shaft and having a first thrust receiving face; a wobble plate having a second thrust receiving face; a thrust bearing sandwiched between the first thrust receiving face and the second thrust receiving face such that the wobble plate is rotatable relative to the rotating base; and a piston engaged with the wobble plate for reciprocation corresponding to wobble movement of the wobble plate. One of the first thrust receiving face and the second thrust receiving face is out of contact with an outer region of the thrust bearing.
- The fourth aspect of the present invention is a compressor including a compressor housing having a first thrust receiving face; a shaft rotatably supported by the housing; a rotor fixed to the shaft to rotate with the shaft and having a second thrust receiving face; a piston configured to reciprocate corresponding to rotation of the rotor; and a thrust bearing sandwiched between the first thrust receiving face and the second thrust receiving face. One of the first thrust receiving face and the second thrust receiving face is out of contact with an outer region of the thrust bearing.

-
FIG. 1 is an overall cross-sectional view showing a compressor according to the first embodiment. As shown inFIG. 1 , thecompressor 1 of the first embodiment is a wobble plate type variable displacement compressor. Thecompressor 1 includes acylinder block 2 having a plurality ofcylinder bores 3 located evenly spaced apart in a circumferential direction, afront head 4 attached to a front end of thecylinder block 2 and having acrank chamber 5 therein, and arear head 6 attached to a rear end of thecylinder block 2 via avalve plate 9 and having asuction chamber 7 and adischarge chamber 8 therein. Thecylinder block 2, thefront head 4, and therear head 6 are fixed to each other by a plurality ofbolts 13 so as to compose a housing of the compressor. - The
valve plate 9 has suction ports (not shown) that allow thecylinder bores 3 to communicate with thesuction chamber 7 anddischarge ports 12 that allow thecylinder bores 3 to communicate with thedischarge chamber 8. - A valve system (not shown) adapted to open and close the suction ports is provided on the
valve plate 9 at the cylinder block side. A valve system (not shown) adapted to open and close thedischarge ports 12 is provided on thevalve plate 9 at the rear head side. - A
drive shaft 10 is supported byradial bearings holes cylinder block 2 and thefront head 4 so that thedrive shaft 10 is rotatable in thecrank chamber 5. A thrust bearing 16 is interposed between athrust receiving face 83 of arotor 21, fixed to theshaft 10, and athrust receiving face 81 of thefront head 4. A thrust bearing 15 is interposed between a step (thrust receiving face) formed on the support bore 19 of thecylinder block 2 and a step (thrust receiving face) formed on theshaft 10. - The
crank chamber 5 accommodates therotor 21 fixed to theshaft 10, asleeve 22 attached to theshaft 10 slidable in the axial direction, a rotatingbase 25 connected to thesleeve 22, such a ball joint structure, so as to be tiltable with respect to the axis of theshaft 10, awobble plate 26 attached to the rotatingbase 25 via aradial bearing 63 and a thrust bearing 61 so as to be rotatable in a circumferential direction with respect to he rotatingbase 25, and alinkage mechanism 40 linking therotor 21 and the rotatingbase 25 to transfer the rotation of therotor 21 to therotating base 25 as allowing changes of the inclination angle of the rotatingbase 25. - Pistons 29 are reciprocatably disposed in the
cylinder bores 3. Eachpiston 29 is connected to the outer region of thewobble plate 26 via a pair of hemispherical-shaped piston shoes 30. - With this structure, when the
rotor 21 rotates with theshaft 10, the rotation of therotor 21 is transferred to the rotatingbase 25 via thelinkage mechanism 40 so that therotating base 25 rotates with therotor 21. When the rotatingbase 25 rotates, thewobble plate 26 wobbles corresponding to the inclination angle of aflange 25 b of therotating base 25, but dose not rotate due to a sliding friction contact with thepiston shoes 30. The wobble of thewobble plate 26 is converted into reciprocation of thepistons 29. By the reciprocation of thepistons 29, refrigerant is sucked from thesuction chamber 7 into thecylinder bores 3 through the suction ports of thevalve plate 9, and compressed in thecylinder bore 3, and discharged to thedischarge chamber 8 through thedischarge ports 12 of thevalve plate 9. - The
compressor 1 of the present embodiment is not a double-ended wobble plate type variable displacement compressor in which thepistons 29 are provided on both sides of thewobble plate 26. The present compressor is a single-ended wobble plate type variable displacement compressor on which thepistons 29 are provided in one side of thewobble plate 26. - Control of Variable Capacity
- The inclination angle of the
wobble plate 26 is changeable. When thewobble plate 26 is moved toward thecylinder block 2 against thereturn spring 52, the inclination angle of thewobble plate 26 decreases. On the other hand, when thewobble plate 26 is moved away from thecylinder block 2 against thereturn spring 51, the inclination angle of thewobble plate 26 increases. - The inclination angle of the
wobble plate 26 corresponds to the piston strokes and the discharging amount of thecompressor 1. A pressure difference (pressure balance) between the crank chamber pressure Pc, in back of thepistons 29, and the suction chamber pressure Ps, in front of thepistons 29, makes a change in the inclination angle of thewobble plate 26 to change piston strokes. Accordingly, thecompressor 1 has a pressure control mechanism. The pressure control mechanism includes a gas extraction passage (not shown) that allows thecrank chamber 5 to communicate with thesuction chamber 7, a gas supply passage (not shown) that allows thecrank chamber 5 to communicate with thedischarge chamber 8, and acontrol valve 33 that is provided in the midstream of the gas supply passage to open and close the gas supply passage. - Connecting Structure Between Wobble Plate and Rotating Base
- A connecting structure between the wobble plate and the rotating base will be described with reference to
FIGS. 1 and 2 . - As shown in
FIGS. 1 and 2 , the rotatingbase 25 is formed with a substantially disk-like shapedflange 25 b and a substantially tubular shapedboss 25 a. Thewobble plate 26 is connected to theflange 25 b via thethrust bearing 61 and to theboss 25 a via the radial baring 63. Thewobble plate 26 is attached to the rotatingbase 25 under a precompression provided in a direction of the thrust load by awasher 65 and an adjustingscrew 67. - The
radial bearing 63 includes a pair ofraces balls 63 c as rolling elements for rolling between the pair ofraces retainer 63 d for retaining theballs 63 c between the pair ofraces thrust bearing 61 includes a pair ofraces needles 61 c as rolling elements for rolling between the pair ofraces retainer 61 d retaining theneedles 61 d between the pair ofraces - The compression reaction force Fp applied to the upper dead center of the
wobble plate 26 or the area around the upper dead center is set off from the axis of theshaft 10, so that a thrust load between the rotatingbase 25 and thewobble plate 26 is off center from the axis of them. In other words, the rotatingbase 25 and thewobble plate 26 relatively rotate in a condition in which thewobble plate 26 is pressed in an inclined manner with respect to the rotatingbase 25. Therefore, outer regions of theneedles 61 c of thethrust bearing 61 are strongly pressed between theraces needles 61 c may be subjected to excessive wear. - In order to prevent such damage of the
needles 61 c, an outer region of therace 61 a is made so as to not contact with athrust receiving face 71. In other words, thetrust receiving face 71 of the rotatingbase 25 has a slot orrelease portion 75 which allows flexure of the outer region of therace 61 a. Therelease portion 75 is defined by a recess 76 (a steppedportion 76 in this embodiment) which is formed on thethrust receiving face 71 of the rotatingbase 25 at an area corresponding to the outer region of therace 61 a. Therecess 76 is recessed from the other parts of thethrust receiving face 71. Therecess 76 is formed in an annular shape along the outer region of thethrust bearing 61 and located at an inner side from outer ends of theneedles 61 c. - Effect
- With the above described structure, the first embodiment achieves about the following effects.
- (1) According to the present embodiment, the outer region of the
race 61 a of thethrust bearing 61 does not contact thethrust receiving face 71. In other words, thecompressor 1 of the present embodiment includes therelease portion 75 that allows elastic deformation of the outer region of therace 61 a of thethrust bearing 61. - Such a structure prevents the outer regions of the
needles 61 c from being damaged by pressure from theraces thrust bearing 61 is deformable even when the rotatingbase 25 and thewobble plate 26 relatively rotate in such a manner that thewobble plate 26 inclines relative to the rotatingbase 25 by the compression reaction force Fp applied around the upper dead center of thewobble plate 26. - (2) According to the present embodiment, the
release portion 75 is defined by the recess (the steppedportion 76 in this embodiment) which is recessed from thethrust receiving face 71 of the rotatingbase 25 at an area corresponding to the outer region of therace 61 a. Accordingly, therelease portion 75 can comprise a simple structure. - In the first embodiment, a
release portion 75 is defined by a recess (a stepped portion 76) which is formed on thethrust receiving face 71 of the rotatingbase 25 at an area corresponding to the outer region of therace 61 a. However, for example, as shown in the second embodiment inFIG. 3 , a recess may be provided as alinear slope 76B. - As shown in the third embodiment in
FIG. 4 , a recess may be provided as acurved slope 76C. - In the first embodiment, a
release portion 75 is formed on only athrust receiving face 71 of a rotatingbase 25. However, for example, as shown in the fourth embodiment inFIG. 5 , arelease portion 77 may be formed, as a steppedportion 78 or the like, on athrust receiving face 73 of awobble plate 26 in addition to therelease portion 75 formed on thethrust receiving face 71 of the rotatingbase 25. - As shown in the fifth embodiment in
FIG. 6 , for example,release portions races - In the above embodiments, the present invention is applied to a structure between the rotating
base 25 and thewobble plate 26, which relatively rotate while sandwiching athrust bearing 61 therebetween. However, as shown in the sixth embodiment inFIG. 7 , the present invention may be applied to a structure between ahousing 4 of thecompressor 1 and arotor 21, which relatively rotate while sandwiching athrust bearing 16 therebetween. According to the sixth embodiment inFIG. 7 , a recess (a steppedportion 86 in this embodiment) is formed on athrust receiving face 81 of thehousing 4, not on athrust receiving face 83 of arotor 21, so as to form arelease portion 85. With this structure, an outer region of arace 16a, which contacts thethrust receiving face 81, can be deformable. - As described above, a compressor according to the present invention includes a first member and a second member that are relatively rotate while sandwiching a thrust bearing therebetween and a release portion that allows deformation of an outer region of one of the races of the thrust bearing. In other words, one of a thrust receiving face of the first member and a thrust receiving face of the second member is not in contact with the outer region of the thrust bearing. This structure prevents a rotating element in the thrust bearing from being excessively worn, since the outer region of one of the races of the thrust bearing is allowed to be deformed even when the first member and the second member relatively rotate when a heavy load is applied to the outer region of the thrust races due to a pressure.
- Although the invention has been described above by reference to certain embodiments of the invention, the invention is not limited to the embodiments described above. Modification and variation of the embodiments can be made without departing from sprit or scope of the appended claims. Therefore, the embodiments are only for illustrative purpose and not limit the invention.
