Abstract

A package of laminations includes a plurality of lamella segments, which are arranged in layers and embodied to be connected together as ring segments. Each of the lamella segments has a plurality of cutouts and at least one of the lamella segments has at least three cutouts. The lamella segments are interconnected via sleeves. A method for manufacturing a package of laminations, a multi-plate coupling employing the package of laminations and an industrial application using the package of laminations are also described.

First claim

What is claimed is:

1. A package of laminations, comprising a plurality of lamella segments, each of the lamella segments having a plurality of cutouts and at least one of the lamella segments having at least three cutouts, wherein the lamella segments are arranged in layers oriented perpendicular to a main axis of rotation and connected together in each layer to form ring segments with a closed circumferential outer contour, with a first lamella segment in a first layer projecting beyond a second lamella segment in a subsequent adjoining second layer so as to overlap a space between two second lamella segments along a circumferential direction.

2. The package of laminations of claim 1 , wherein the first lamella segment is connected to the second lamella segment with a partial overlap via a sleeve at at least two cutouts.

3. The package of laminations of claim 2 , comprising six or eight sleeves.

4. The package of laminations of claim 2 , wherein the package of laminations has a degree of lamella filling of at least 60% in a curved section between two sleeves, whereas the degree of lamella filling is defined as a quotient of a number of load-bearing sections present in the package of laminations divided by the number of load-bearings sections when the lamella segments were to be replaced by one-piece ring lamella.

5. The package of laminations of claim 2 , comprising a plurality of sleeves, with at least one sleeve having a cross section different from a circular shape.

6. The package of laminations of claim 1 , wherein all lamella segments have an identical number of cutouts.

7. A method for manufacturing a package of laminations having a plurality of lamella segments embodied as ring segments, with each ring segment having at least three cutouts for accommodating a sleeve, said method comprising:
determining a separation pattern for the plurality of lamella segments;
separating the plurality of lamella segments from a blank sheet of metal commensurate with the separation pattern; and
arranging the separated lamella segments in layers oriented perpendicular to a main axis of rotation and connecting the separated lamella together in each layer to form ring segments with a closed circumferential outer contour, with a first lamella segment in a first layer projecting beyond a second lamella segment in a subsequent adjoining second layer so as to overlap a space between two second lamella segments along a circumferential direction.

8. The method of claim 7 , wherein the separation pattern defines a plurality of contours of nested lamella segments.

9. The method of claim 7 , wherein the blank sheet of metal is constructed from a cold-rolled stainless steel.

10. A multi-plate coupling, comprising:
a first flange;
a second flange; and
a package of laminations releasably connecting the first flange to the second flange for transmission of a torque, said package of laminations comprising a plurality of lamella segments, with each of the lamella segments having a plurality of cutouts and at least one of the lamella segments having at least three cutouts, wherein the lamella segments are arranged in layers oriented perpendicular to a main axis of rotation and connected together in each layer to form ring segments with a closed circumferential outer contour, with a first lamella segment in a first layer projecting beyond a second lamella segment in a subsequent adjoining second layer so as to overlap a space between two second lamella segments along a circumferential direction.

11. An industrial application, comprising:
a drive unit having an output shaft;
a driven unit having an input shaft; and
a coupling connecting the output shaft to the input shaft for torque transmission, wherein the coupling is constructed as a multi-plate coupling and comprises a first flange, a second flange, and a package of laminations releasably connecting the first flange to the second flange for transmission of a torque, said package of laminations comprising a plurality of lamella segments, with each of the lamella segments having a plurality of cutouts and at least one of the lamella segments having at least three cutouts, wherein the lamella segments are arranged in layers oriented perpendicular to a main axis of rotation and connected together in each layer to form ring segments with a closed circumferential outer contour, with a first lamella segment in a first layer projecting beyond a second lamella segment in a subsequent adjoining second layer so as to overlap a space between two second lamella segments along a circumferential direction.
