Definitions
- Spiral compressor in particular for use in compressed air generation for rail vehicles
- the invention relates to a scroll compressor according to the preamble of claim 1.
- the object of the invention is to design a preferably completely oil-free scroll compressor with a one-sided scroll arrangement such that an exact relative position of the two scrolls is ensured even with a large intake volume flow and also with large compression ratios; in particular, no unnecessary frictional engagement leading to jamming should occur during the relative movement of the two spirals required to form the compression pockets.
- the support rollers Due to the forced guidance with the aid of the support rollers, a so-called “anti-rotation mechanism” between the spirals is provided, ie this does not prevent the spirals from rotating relative to the housing, but rather prevents the two spirals from rotating relative to one another these orbiting movements towards each other, which are necessary to create the suction and compression pockets for generating the compressed air, the support rollers are thus advantageously effective as a driver of one spiral over the other spiral, at the same time they mediate due to the degree of freedom of their rolling movement the necessary relative movement in the bore to form the suction and pressure pockets.
- Figure 1 of the drawing is a sectional view of the scroll compressor according to the invention.
- Figure 2 is an enlarged sectional view of one of the support rollers within the bore embedded in the pressure ring.
- FIG. 1 of the drawing shows a scroll compressor 1 provided with a one-sided scroll arrangement. This is provided with a housing 3 in which two interlocking spirals run, namely a spiral 7 driven by a shaft 5 and a spiral 9 dragged by the spiral 7.
- the two spirals each perform a pure rotational movement; due to the purely rotary movement of the spirals, no unbalance forces occur, provided the spirals are balanced in each case.
- the orbiting relative movement of the two spirals relative to one another required for a compression effect is produced by the axes of rotation 11 and 13 of the two spirals being at a certain distance from one another. Furthermore, the dragged spiral 9 is encompassed by a pressure ring 15, which is screwed to the driven spiral 7 (via fastening means, not shown) or is connected in some other way.
- an "anti-rotation mechanism” acts in the form of a forced guidance between the two spirals, which consists of three of the towed spiral 9 supported support rollers 17, which run at the same angular distance from each other bores 19 in the pressure ring 15. Accordingly, three support rollers arranged at an angular distance of 120 ° from each other are assigned to three bores 19 arranged at the same angular distance from one another.
- FIG. 2 shows an enlarged sectional view of one of the support rollers 17 within the bore 19 that guides it.
- the bore 19 is formed in the illustrated embodiment as a guide ring such that a steel sleeve 20 is provided for the wear-free support of the support roller.
- the support rollers can have an elastic plastic sleeve (not shown) on their outer circumference or they can be plastic-coated.
- the attachment of the support rollers to the spiral 9 is provided in the exemplary embodiment shown in FIG. 2 by means of screws 22, which enable the support rollers to be exchanged in a simple manner.
- a device for axial force compensation is provided.
- This device consists of pressure chambers 35, which are provided between the inside of the pressure ring 15 and an annular disk 37 attached to the rear of the spiral 9.
- the pressure chambers 35 are the very low volumes, each between the Washer 37 and the facing inner surface of the pressure ring 15 exist.
- the size and shape of the pressure chambers is determined by dry-running seals 39 which hold the pressure chambers Seal against outside air, ie against the outside air volume between cooling air inlet 40 and cooling air outlet 41 of the spiral 9.
- three pressure chambers 35 are provided between the bores 19 at the same angular distance of 120 ° to one another, each of which is supplied with compressed air from the compression pockets 45 of the spirals via bores 43.
- a pressure builds up in these due to the pressure supply of the pressure chambers 35 described above, which presses the two scrolls towards one another, since the pressure ring 15 is connected to the scroll 7 and the annular disk 37 in the rear region of the scroll 9 thereof is worn, e.g. by means of radial cooling ribs 47 connected to the spiral 9 or by the bearing journals of the support rollers 17 which penetrate the annular disc 37 at an angular distance from one another, as can be seen in the upper half of the drawing.
- a corresponding cooling system is also provided on the spiral 7, ie there is a cooling air inlet 49 and a cooling air outlet 51; furthermore, radial cooling fins 53 connected to the spiral 7 are provided.
