がら説明する。 The present invention prevents the rotation of the oscillating scroll by meshing gears with the same number of teeth between the oscillating scroll and the fixed scroll. I will explain while referring to it.

側歯車で、鏡板２ａの外周側面に形成してある。 Reference numeral 1 denotes a fixed scroll comprising an end plate 1a and a blade 1b formed into an involute curve or a curve similar thereto, and 2 an oscillating scroll comprising an end plate 2a and a blade 2b. 3
is a drive shaft that drives the swinging scroll 2, and the eccentric pin 3a is connected to a bearing 2c of the swinging scroll 2 via a bearing 4. Reference numeral 5 denotes a fixed side gear having a number of teeth Z and a module M, which is fixed to the fixed scroll 1, and is in the form of a ring-shaped internal gear, and is fixed with a bolt 6. Reference numeral 7 denotes a swing gear having a number of teeth Z and a module M' that meshes with the fixed gear 5, and is formed on the outer circumferential side of the mirror plate 2a.

定スクロール１に対して揺動する。 In this configuration, the rotation of the drive shaft 3 causes the swing scroll 2 to rotate while the swing gear 7 is inscribed in the fixed gear 5. At this time, the number of teeth Z of the fixed side gear 5 and the number of teeth Z of the oscillating side gear 7 are the same, and the modules M and M' are engaged with each other in different ways, so the oscillating scroll 2 does not rotate on its own axis. First, it swings relative to the fixed scroll 1.

等に適用できる。 It should be noted that the meshing of gears of different modules can be carried out without any problem in practice by increasing the number of teeth and setting an appropriate amount of eccentricity between the fixed and swinging sides, although undercut may occur. Also,
It can be applied not only to the illustrated compressor but also to expanders, fluid motors, etc.

能の劣化を防ぐ効果を有する。 As described above, the present invention includes an oscillating scroll;
and a fixed scroll, wherein the swinging scroll is provided with a swinging side gear, the fixed scroll is provided with a fixed side gear having the same teeth as the swinging side gear, and the swinging side gear and the fixed side gear are provided with a fixed side gear. It is made up of meshing gears, and the gears prevent the oscillating scroll from rotating, preventing uneven wear of the scroll, and preventing deterioration of performance.
