Patent ID: 7387574

Claim:
A production series of adapter devices, the production series including at least one size, each size including at least one variant, each adapter device including: an adapter shaft configured to connect to a device to be driven; an intermediate piece engaged with the adapter shaft; and a sub-component engaged with the intermediate piece and configured to connect to an input shaft; wherein each variant includes: a diameter A_i of a bore hole arranged to accommodate the input shaft in the sub-component; the intermediate piece; and a diameter D_i at an end of the adapter shaft facing away from the intermediate piece; wherein i represents a numbering index; wherein the diameters A_i of the bore holes are included in a standardized motor grading; wherein with increasing characteristic power, the diameters D_i at least do not become smaller; wherein each intermediate piece includes radial sections arranged so that at a greatest power provided for at least one of the intermediate piece and the characteristic power, the radial sections are subjected to a value of compressive load per unit area within a single tolerance range in accordance with an entire production series; wherein at least one of: at least one intermediate piece is used in variants of at least two different sizes; and at least one intermediate piece is used for sub-components having different diameters A_i of the bore hole to accommodate the input shaft and for adapter shafts having different diameters D_i in a region of a feather keyway of the adapter shaft; wherein the sub-component includes a bore hole configured to accommodate the input shaft and is connectable to the input shaft by a feather key connection.
