DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to a coupling for coupling non-aligned rotating parts with driving-side and driven side coupling halves and an intermediate coupling member consisting of separable parts, said intermediate coupling member being connected with the driving-side coupling half through a first pair of mutually centro-symmetrically arranged links and being connected with the driven side coupling half through a second pair of mutually centro-symmetrically arranged links.
UNDERLYING PRIOR ART
Such a coupling is known, for example, from DE-A-3,049,054.
DISCLOSURE OF INVENTION
It is the object of the invention to simplify the design of a coupling mentioned in the beginning.
According to the invention, this object is achieved in that intermediate member halves, intermediate member half defines a lateral opening, which permits lateral removal of the intermediate member half from a shaft passing centrally through the coupling, whereby the opening of each intermediate member half is aligned with the closed median portion of the other intermediate member half, side by side in the regions of each of its ends on both sides of a plane of symmetry extending between the two intermediate member halves, the first lug being provided on the side of the opening, and the second lug being provided on the side of the closed median portion, second lugs of the other intermediate member half and vice versa, and
Modifications of the invention are subject matter of the subclaims.
An embodiment of the invention is described hereinbelow with reference to the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a view of a coupling as viewed in axial direction, the coupling halves, which may be part of a machine installation, for example a transmission shaft and a railroad engine, are not shown.
FIG. 2 is a sectional view taken along line C-D of FIG. 1.
FIG. 3 shows an individual intermediate member half of the coupling of FIG. 1, viewed in axial direction.
FIG. 4 shows an associated side elevation.
PREFERRED EMBODIMENT OF THE INVENTION
In FIG. 1 numeral 10 designates an intermediate coupling half of a coupling. The coupling couples two rotating parts, for example the transmission shaft and a wheel of a railroad engine, through a first coupling half A and a second coupling half B, respectively. The intermediate coupling member 10 is connected with the driving-side coupling half A through a link 12 and a link 14 arranged centro-symmetrical with respect to the link 12. Furthermore, the intermediate coupling member 10 is connected with the driven-side coupling half through a link 16 and a link 18. The links 12 and 14 extend clockwise around the intermediate coupling member 10. The links 16 and 18 extend counter-clockwise around the intermediate coupling member 10. The coupling permits a certain offset of the axes of driving-side and driven-side coupling halves. With such offset, the links 12 to 18 and the intermediate coupling member carry out a compensating movement.
In the illustrated coupling the intermediate coupling member 10 consists of two intermediate member halves 20 and 22. The intermediate member halves 20 and 22 can be separated radially, after bolts have been detached. Thereby it is possible to dismantle a coupling through which a wheel axle passes, without having to remove the wheel therefor.
An intermediate member half 22 is illustrated separately in FIG. 3 and 4 in an axial view and side elevation, respectively. The intermediate member half 22 extends circumferentially through slightly more than 180.degree. about the axis 24. The intermediate member half 22 has an outwardly curved median portion 26 and two ends 28 and 30. The median portion 26 defines an opening 32 (on the right side in FIG. 3), which permits lateral removal of the intermediate member half from a shaft or axle passing through the coupling. A first and a second lug 46 and 48 are integral with the end 28 of the intermediate member half (at the top left end in FIG. 4). The two lugs 46 and 48 are symmetrical with respe
