- the disk holding portion 35b is a portion that is inserted into the mounting opening 63 of each separation disk 61, 62. Since this disk holding part 35 b is a part of the upper holder 35, it rotates together with the spindle 32.
- the disk holding portion 35 b is engaged with the opening edge (vertex portion) of the attachment opening 63 to restrict movement of the separation disks 61 and 62 in the rotation direction.
- the disk holding portion 35b of the present embodiment is composed of eight elongated plate-like members 35c extending in the axial direction of the spindle 32.
- Each plate-like member 35c is directed in the radial direction from the center of rotation, and is arranged in the circumferential direction at intervals of 45 degrees.
- the respective apexes of the attachment openings 63 are aligned with the edge portions of the plate-like members 35c, and the separation discs 61 and 62 are inserted.
- the separation disks 61 and 62 are stacked in the axial direction of the spindle 32.
- the 2nd rib 65 is arrange
- the mounting openings 63 of the first separation disk 61 and the second separation disk 62 are regular octagons, and the 24 first uneven ribs 64 and the second uneven ribs 65 are formed at intervals of 15 degrees in the circumferential direction. Further, the shift amount of the first uneven rib 64 and the second uneven rib 65 with respect to the mounting opening 63 in the circumferential direction is set to 7.5 degrees. As a result, by simply attaching the first separation disk 61 and the second separation disk 62 to the disk holding portion 35b alternately, the positions of the concave and convex ribs 64 and 65 in the circumferential direction can be determined. The second uneven rib 65 can be disposed between the 64. As a result, it is possible to improve workability when the separation disks 61 and 62 are stacked on the disk holding portion 35b.
- the rotor 31 holds a large number of separation disks 34 (first separation disk 61 and second separation disk 62) in a stacked state.
- corrugated rib 65 are arrange
- corrugated rib 64,65 is staggered arrangement
- FIG. 11B shows a state in which a plurality of comparative separation disks 81 are stacked.
- a rib 83 having a rectangular cross section is provided on the outer peripheral side portion 82. That is, the separation disk 81 is also formed of a truncated cone-shaped plate member, and a plurality of ribs 83 are provided in the radial direction from the center of rotation.
- a plurality of separation disks 81 are laminated so that the ribs 83 overlap each other.
- the positions of the first uneven rib 64 and the second uneven rib 65 are shifted in the circumferential direction.
- the thin portions of the disks 61 and 62 are slightly curved, and the thickness when the four separation disks 61 and 62 are stacked is d1.
- the thickness in the state where the four separation disks 81 are stacked is d2, which is thicker than the present embodiment.
- the oil mist separation efficiency can be increased as the number of separation disks 34 is increased. And if it is the same height range, since many separation discs 34 can be laminated
- FIG. 12A is a plan view of the first separation disk 71 in the second embodiment.
- FIG. 12B is a plan view of the second separation disk 72 in the second embodiment.
- the first separation disk 71 of the second embodiment has a first convex portion 76 in which the front surface side of the outer peripheral side portion is convex and the rear surface side is concave, and the rear surface side is convex and the front surface side is concave.
- corrugated rib 74 by which the formed 2nd convex part 77 was formed alternately is provided.
- the first uneven rib 74 extends in the radial direction from the rotation center CP of the first separation disk 71 at the outer peripheral side portion of the first separation disk 71.
- the first separation disk 71 has 24 first uneven ribs 74 formed at equal intervals in the circumferential direction.
- the second separation disk 72 is similarly configured. That is, 24 second uneven ribs 75 in which the second protrusions 77 and the first protrusions 76 are alternately formed are formed on the second separation disk 72 at equal intervals in the circumferential direction.
- a regular octagonal mounting opening 73 is formed in the center side portion of each separation disk 71, 72.
- the formation position of each first uneven rib 74 in the circumferential direction and the formation position of each second uneven rib 75 in the circumferential direction with reference to the mounting opening 73 are as follows. The same. For this reason, as shown in FIG. 13A, each apex of the mounting opening 73 is set along the edge of each plate-like member 35c, and the first separation disk 71 and the second separation disk 72 are alternately provided to the disk holding portion 35b. Is attached, the first uneven rib 74 and the second uneven rib 75 are brought into contact with each other.
- the second convex portion 77 of the first concave / convex rib 74 and the first convex portion 76 of the second concave / convex rib 75 abut.
- the first convex portion 76 of the first concave / convex rib 74 and the second convex portion 77 of the second concave / convex rib 75 also abut.
- the first convex portions 76 and the second convex portions 77 included in the first concave and convex ribs 74 and the second concave and convex ribs 75 are also thin. For this reason, each separation disk 71 and 72 can be reduced in weight.
- the first concave and convex ribs 74 and the second concave and convex ribs 75 are in contact with each other, thereby forming a plurality of holes penetrating in the circumferential direction.
- the oil moves on the surfaces of the separation disks 71 and 72. At that time, the oil moves along a complicated route by a plurality of newly formed holes. For example, the movements in the circumferential direction are restricted by the first uneven ribs 74 and the second uneven ribs 75 so that the oils are combined. Thereafter, the oil passes through the newly formed hole, and movement in the circumferential direction is restricted by another first uneven rib 74 and second uneven rib 75. By performing such an operation, the oils can be easily combined with each other, and the oil mist separation efficiency can be increased.
- the attachment openings 63 and 73 of the separation disk 34 are regular octagons in the above-described embodiments, but may be other regular polygons.
- the first concavo-convex ribs are provided in the circumferential direction at intervals of 1/3 times the internal angle ⁇ (60 degrees) in regular hexagons (20 degree intervals), and the second rib concavo-convex is 1 of the internal angle ⁇ with respect to the first concavo-convex ribs.
- What is necessary is just to provide in the circumferential direction by the 1/3 time space
- the first concavo-convex ribs are provided in the circumferential direction at intervals of 1/3 times the interior angle ⁇ (36 degrees) in the regular decagon (intervals of 12 degrees), and the second concavo-convex ribs are provided. What is necessary is just to provide in the circumferential direction by the 1/3 time space
- the first concave and convex ribs are provided in the circumferential direction at intervals of 1 / n times the inner angle of the regular polygon. It only has to be done.
- the second uneven ribs only need to be provided in the circumferential direction at intervals of 1 / n times the inner angle ⁇ at positions shifted in the circumferential direction by 1 / 2n times the inner angle ⁇ with respect to the first uneven rib.
- the disk holding portion 35b in the above-described embodiment, an example in which a plurality of elongated plate-like members 35c are used is exemplified, but the present invention is not limited to this configuration.
- the disc holding part may be constituted by a cylindrical member having a regular polygonal cross section in which a large number of air holes are opened in the wall part.
- the present invention is not limited to a configuration in which two types of separation disks are alternately stacked. That is, it is good also as a structure which laminates
