A gear includes a first, radially inner ring element, a second, radially outer ring element and a connecting element, wherein the second, radially outer ring element includes a toothing, wherein further the connecting element is arranged in the radial direction between the first, radially inner ring element and the second, radially outer ring element and is connected to the first, radially inner ring element and the second, radially outer ring element, and wherein the connecting element is made at least partly from a rubbery-elastic material, and wherein a deviation of the coaxiality of the outer diameter of the first, radially inner ring element to the inner diameter of the second, radially outer ring element amounts to a maximum of 0.8 mm and/or the toothing of the radially outer ring element is formed with teeth having different tooth thicknesses.
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 (8), wherein further the connecting element (4) is arranged in the 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 rubbery-elastic material, wherein a deviation of the coaxiality of the outer diameter (9) of the first, radially inner ring element (2) to the inner diameter (10) of the second, radially outer ring element (3) amounts to a maximum of 0.8 mm and/or the toothing (8) of the radially outer ring element (3) is formed with teeth (11) having different tooth thicknesses (12).
A method for producing a gear (1) comprising the steps:
A device (30) for producing 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 connecting element (4) is arranged in the 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 rubbery-elastic material, having a mold (31) with a mold cavity for receiving the first, radially inner ring element (2) and the second, radially outer ring element (3) at a distance from the first, radially inner ring element (2) forming an intermediate space (29), and having at least one feed unit (32) for a vulcanizable or polymerizable mass for producing the connecting element (4), wherein the device (30) further comprises a centering unit (33), which respectively engages in at least one recess in an end face (14) of the first, radially inner ring element (2) and in an end face (16) of the second, radially outer ring element (3) for centering the first, radially inner ring element (2) and the second, radially outer ring element (3) with respect to one another.
