Cord package supporting device, elastic joint disk and method for producing an elastic joint disk
A cord package supporting device for supporting a cord package wound with a cord, such as for an elastic joint disk for connecting two shaft portions, is disclosed. The cord package includes two opposite arcuate cord regions and two tangential cord regions that connect the arcuate cord regions to each other and extend parallel to each other. In embodiments, the cord package supporting device includes a first redirecting portion and a second redirecting portion, about which in each case one arcuate cord region of the cord package is guided. In embodiments, the two redirecting portions are integrally connected to each other via a web. An elastic joint disk and a method for producing an elastic joint disk are also disclosed.
1. A cord package, comprising:
a cord; and
a cord package supporting device including a first redirecting portion and a second redirecting portion, the first and second redirecting portions are integrally connected via a web, and arcuate cord regions of the cord are guided about the first and second redirecting portions;
wherein the first and second redirecting portions include two opposite collar portions, and at least a portion of the cord is disposed between the collar portions.
2. The cord package according to claim 1 , wherein the web can be detached from the redirecting portions.
3. The cord package according to claim 2 , wherein each of the redirecting portions has at least one depositing region for depositing the cord package supporting device for detaching the web.
4. The cord package according to claim 1 , wherein the cord package is axially supported by the collar portions of the first and second redirecting portions.
5. The cord package according to claim 4 , wherein a distance between the opposite collar portions in the region of a tangential cord guidance increases steadily.
6. The cord package according to claim 1 , wherein each redirecting portion has an arcuate cord guiding region around which an arcuate cord region is guided, and two tangential cord guiding regions, wherein each of the tangential cord guiding regions guides a portion of a tangential cord region.
7. The cord package according to claim 1 , wherein each of the redirecting portions has a through-hole for pressing in a bushing and a ridge portion for fastening the web.
8. The cord package according to claim 1 , wherein an elastomer body partially encases the cord package supporting device.
9. The cord package according to claim 1 , wherein the redirecting portions and the web are produced integrally by injection molding.
10. The cord package device claim 1 , wherein the two redirecting portions and the web are produced from a plastic.
11. The cord package according claim 10 , wherein the plastic comprises fiber reinforced plastic.
12. A method for producing an elastic joint disk for connecting two shaft portions, the method comprising:
providing a plurality of cord package supporting devices, wherein each cord package supporting device comprises two redirecting portions and a web integrally connecting the two redirecting portions to each other, and wherein each redirecting portion has a through-hole for pressing in a bushing;
winding a cord around each of the cord package supporting devices to produce a cord package on each of the cord package supporting devices;
partially encasing each of the cord package supporting devices with an elastomer body; and
connecting the cord package supporting devices, which are partially encased with an elastomer body, to each other by means of a plurality of bushings to form a joint disk, by one bushing in each case being pressed into the through-holes of two cord package supporting devices.
13. The method according to claim 12 , wherein the web is detached from the redirecting portions after each of the cord package supporting devices has been partially encased with an elastomer body.
14. The method according to claim 12 , wherein the cord package supporting devices are encased.
15. The method according claim 14 , wherein the cord package supporting devices are encased prior to winding the cord.
16. A method for producing an elastic joint disk for connecting two shaft portions, the method comprising:
providing a plurality of cord package supporting devices, wherein each cord package supporting device comprises two redirecting portions and a web integrally connecting the two redirecting portions to each other, and wherein each redirecting portion has a through-hole for pressing in a bushing;
winding a cord around each of the cord package supporting devices to produce a cord package on each of the cord package supporting devices;
connecting the cord package supporting devices to each other by means of a plurality of bushings to form a joint disk basic body, by one bushing in each case being pressed into the through-holes of two cord package supporting devices; and
partially encasing each of the cord package supporting devices with an elastomer body.
