Abstract
Official abstract text for this publication.
The invention relates to a gear ( 1 ) comprising a first, radially inner ring element ( 2 ), a second, radially outer ring element ( 3 ) and a connecting element ( 4 ), wherein the second, radially outer ring element ( 2 ) comprises a toothing ( 10 ), wherein the connecting element ( 3 ) is arranged in radial direction between the first, radially inner ring element ( 2 ) and the second, radially outer ring element ( 3 ) and is connected to the first, radially inner ring element ( 2 ) and the second, radially outer ring element ( 3 ), and wherein the connecting element ( 4 ) is made at least partly from a rubber-elastic material. In this case edges ( 11, 12 ) of the first, radially inner ring element ( 2 ) in the connecting area between the first, radially inner ring element ( 2 ) and the connecting element ( 4 ) and edges ( 16, 17 ) in the connecting area between the second, radially outer ring element ( 3 ) and the connecting element ( 4 ) are provided with a rounding ( 21 to 24 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A gear comprising a radially inner ring element having a first radial surface and first axial end faces, a radially outer ring element having a second radial surface and second axial end faces, and a connecting element, the radially outer ring element comprising a toothing, the connecting element being arranged in a radial direction between the radially inner ring element and the radially outer ring element and being connected to the radially inner ring element and the radially outer ring element, and the connecting element comprising a rubber-elastic material, wherein edges between the first radial surface and the first axial end faces of the radially inner ring element and edges between the second radial surface and the second axial end faces of the radially outer ring element are rounded. 2. The gear as claimed in claim 1 , wherein the connecting element extends projecting in an axial direction over the radially inner ring element and the radially outer ring element and in the radial direction partly overlaps the radially inner ring element and the radially outer ring element. 3. The gear as claimed in claim 2 , wherein the radially inner ring element comprises on at least one axial end face at least one recess or the radially outer ring element on at least one axial end face comprises at least one recess and the connecting element engages in the recess or the recesses. 4. The gear as claimed in claim 3 , wherein edges of the recesses in the axial end faces are also rounded. 5. The gear as claimed in claim 1 , wherein the radially inner ring element on at least one radial surface comprises at least one recess or the radially outer ring element on at least one radial surface comprises at least one recess and the connecting element engages in the at least one recess. 6. The gear as claimed in claim 5 , wherein edges of the recesses in the radial surfaces are also rounded. 7. The gear as claimed in claim 1 , wherein the connecting element is vulcanized onto the radially inner ring element and the radially outer ring element. 8. The gear as claimed in claim 1 , wherein the radially inner ring element is arranged on an unbalance element.
