Split Can

Abstract

A split can for a magnetic coupling includes a cylindrical jacket region and a base region connected to a first end of the jacket region. The jacket region has an inner wall and an outer wall enclosing the inner wall. The inner wall and the outer wall are spaced apart from each other in the radial direction by a gap, with the inner wall being integrally joined to the outer wall by a plurality of webs. The gap may be provided with a control medium which may be monitored to detect changes in one or more characteristics of the control medium indicative of split can leakage.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0031] FIG. 1 shows a split can according to an embodiment of the invention with webs which extend in the longitudinal direction as a cross section in a radial direction,

[0032] FIG. 2 shows a split can according to FIG. 1 as a cross section A-A,

[0033] FIG. 3 shows a split can according to another embodiment of the invention with webs which extend in a peripheral direction as a cross section in the longitudinal direction,

[0034] FIG. 4 shows a split can according to FIG. 3 as a cross section B-B.

DETAILED DESCRIPTION

[0035] FIGS. 1 and 2 show in a simplified illustration an embodiment of the split can according to the invention having webs (8) which extend in the longitudinal direction (L). The covering region (1) is configured with double walls and has an inner wall (3) and an outer wall (4), which are spaced apart from each other in a radial direction (R). The webs (8) are arranged between the inner wall and outer wall (3, 4) and constructed integrally with the inner wall and the outer wall (3, 4).

[0036] At a first end of the covering region (1), the split can is closed by means of a shell-like base region (2). The base region (2), in the example shown, does not have a double-walled configuration but instead ribs which are not illustrated and via which the base region (2) is reinforced. However, it is within the scope of the invention for the base region to be constructed in a double-walled manner.

[0037] On the whole, in the peripheral direction (U) 32 webs (8) are provided, wherein the number is not limited to this. The webs (8) are in this instance configured in such a manner that the gap (5) between the webs (8) is sub-divided into elliptical channel portions. These channel portions may, for example, be filled with a gaseous or a fluid control medium.

[0038] To this end, in the outer wall (4) at a second end of the split can there is provided an opening (6) via which the control medium can be introduced. The gap (5) or the channel portions extend along the entire covering region (1). The split can may also be configured in such a manner that a heating or cooling capability is possible.

[0039] At the second end of the split can there is further arranged a flange (7) via which the split can be secured in a magnetic clutch. The flange (7) is also illustrated only in simplified form and generally has apertures for receiving securing means, for example, screws.

[0040] FIGS. 3 and 4 show an alternative embodiment of the split can according to the invention in which the webs (8) extend between the inner wall (3) and the outer wall (4) in a peripheral direction (U) and are arranged in the longitudinal direction (L) one above the other in the covering region (1). In this instance, there are also formed in the gap (5) elliptical channel portions which are arranged between the individual webs (8). The shell-like base region (2) is also free from webs (8) here.

[0041] The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
