- the compressor of the first embodiment has a basic configuration substantially the same as that shown in FIGS. 11 and 12, and employs a swash plate 18 shown in FIGS. 1 to 6 and a washer 19 as an alignment member. The difference is that the return panel 21 shown in Fig. 1 is employed.
- the swash plate 18 used in this compressor has A through hole 20 similar to that of the compressor shown in FIG. That is, as shown in FIG. 3, a support portion 20 b is formed in the through hole 20 in an arc shape centered on the pivot center Y, and the regulating surface 20 extends in parallel with the axis X. a, 20a are formed flat on the side surface.
- the pivot center Y extends in a direction perpendicular to the axis X shown in FIG. 11 and is set beyond the drive shaft 6 on the side opposite to the hinge mechanism K, ⁇ across the axis X. As shown in FIG.
- the regulating surfaces 20a and 20a of the through holes 20 are connected to the drive shaft 6 so that the posture and position can be changed according to the tilt displacement of the swash plate 18. It is held with a certain clearance t1 between them.
- the clearance t1 is relatively large because the posture and the position can be changed according to the inclination displacement of the swash plate 18 and the through hole 20 has a complicated shape.
- the through hole 20 of the swash plate 18 in this compressor differs from the through hole 20 of the swash plate 11 in the conventional compressor in the following points.
- the swash plate 18 is formed at the edge of the front of the through hole 20 (the side of the row 10 is the front.
- Tapered surfaces 20 g and 20 h having an opening angle of 45 ° forming a small diameter on one side are formed, and the two tapered surfaces 20 g and 20 h are connected by a smooth curved surface 20 i.
- the double tapered surfaces 20 g and 20 h and the smooth curved surface 20 i are formed as follows. First, as shown in FIG. 2, a cutting tool B having a tapered surface with an opening angle of 45 ° at the tip is prepared, and a through hole 20 shown in FIG. 12 is formed in the swash plate 18. The blade B is advanced from the front side with respect to the swash plate 18 so that the axis of the blade B is aligned with the center line A 1 in the direction orthogonal to the center plane C of the swash plate 18. At this time, the center line A 1 coincides with the axis X. In this way, as shown in FIG. 3, a tapered surface 20 g surrounded by reference characters abgh is formed on the top dead center position T side of the swash plate 18.
- the center of rotation Z which is the same distance as the distance from the center plane C to the pivot center Y, is on the center line A1, and the axis of the cutting tool B is on the center line A2.
- Gently rock the swash plate 18 so that It is also possible to swing the axis of the cutting tool B without moving the swash plate 18.
- the angle 0 between the center line A 1 and the center line A 2 is a displaceable angle which is the difference between the maximum tilt angle and the minimum tilt angle.
- a smooth curved surface 20i surrounded by the symbol bcfg is formed.
- a taper surface 2Oh surrounded by the reference symbol cdef is formed on the lower dead center position side of the swash plate 18.
- the angle 6> between the center line A 1 and the center line A 2 may be slightly widened on both sides, and may be slightly larger than the displaceable angle of the swash plate 18. More specifically, the displacement angle can be increased by 1 to 2 ° on the center line A1 side and by 10 to 15 ° on the center line A2 side. In this case, the contact between the swash plate 18 and the washer 19 does not hinder the tilt displacement of the swash plate 18 and does not reduce the capacity of the compressor.
- the rotation center Z at the time of processing does not necessarily need to be on the center line A 1, but may be located on the pivot center Y side or the opposite side from the center line A 1, and further in the axial direction. It is also possible to shift.
- the cutting tool B After moving the cutting tool B from the front side with respect to the swash plate 18 so that the axis of the cutting tool B is aligned with the center line A1, the cutting tool B is temporarily retracted, and then the cutting tool B is moved. Swing the swash plate 18 and the blade B so that the axis is on the center line A2, and then move the blade B against the swash plate 18 so that the axis of the blade B is aligned with the center line A2 again. You can also move from the front. In this case, the smooth curved surface 20 i surrounded by the symbol bcfg shown in Fig. 3 is not formed, and the tapered surface surrounded by the symbol acfh and the tapered surface surrounded by the symbol cdef are formed.
- the tapered surface 20 g and 2 Oh are connected by a smooth curved surface 20 i because the swash plate 18 and the drive shaft 6 are less likely to be relatively abraded when connected by a smooth curved surface 20 i. Processing such as 0 g is preferred.
- the swash plate 18 has a through hole 18a for balance, weight reduction, and positioning during machining, and penetrates the top dead center position T side.
- a lance and a counterbore 18b for weight reduction are recessed at the bottom dead center position side.
- a boss 10 formed at the rear end of the mouth 10 is provided on the weight 18 c integrally provided on the bottom dead center position side of the swash plate 18.
- a recess 18 d is provided to avoid b, and below the recess 18 d, as shown in FIG. 6, comes into contact with the rear end face 10 a of the mouth 10 to further increase the inclination angle.
- the front end face 1 1a that regulates the This compressor employs washers 19 shown in Fig. 1 and Figs.
- the washer 19 has a substantially cylindrical shape having an inner diameter D slightly larger than an outer diameter of a portion of the drive shaft 6 located in the through hole 20 of the swash plate 18.
- the degree to which the inner diameter D is larger than the outer diameter of that portion of the drive shaft 6 is, as shown in FIG. 5, a dimension in which the washer 19 is fitted to the drive shaft 6 and is slidable in the axial direction. This is the clearance t2 based on the tolerance required when processing this.
- the clearance t 2 can be easily made smaller than the clearance tl of the regulating surfaces 20 a and 20 a of the through holes 20 in the swash plate 18. .
- a tapered surface 19a having an opening angle of 45 ° and having a small diameter on the inner side of the swash plate 18 is also formed at the rear edge of the washer 19.
- the washer 19 is urged rearward by an inclination-reducing panel 12 provided between the washer 10 and the mouth 10.
- a return panel 21 is employed.
- the return panel 21 biases the swash plate 18 from the rear side in a direction in which the inclination angle of the swash plate 18 increases from the minimum inclination angle to the limit angle at which the swash plate 18 can return.
- the swash plate 18 when the compressor is performing a compression operation with a relatively large discharge capacity, the swash plate 18 is in contact with the drive shaft 6 and the washer 19 due to the compression load.
- the taper surface 19a of the swash plate 18 is tilted and displaced in contact with the smooth curved surface 20i of the swash plate 18.
- this compressor performs the compression operation with a small discharge capacity that is not performing the compression operation or that can be regarded as substantially zero without obstructing the tilt displacement of the swash plate 18 due to the variable capacity. In such a case, it is possible to prevent problems such as noise.
- the inclination reducing panel 12 biases the washer 19, there is no need for a biasing member for biasing only the washer 19, and the number of parts is reduced, thereby reducing the cost of the product.
- Other functions and effects are the same as those of the compressor described in the above publication.
- the portion where the swash plate 18 contacts the washer 19 has a tapered surface 20 g in which the inside of the swash plate 18 has a small diameter.
- the portion where the washer 19 contacts the swash plate 18 is a convex curved surface 19b.
- Other configurations are the same as in the first embodiment. With this compressor, processing can be facilitated and product costs can be reduced. Other functions and effects are the same as those of the first embodiment.
