Abstract

Examples are provided that describe a cycloid transmission with a chain link ring. An example cycloid transmission includes a motor shaft attached to a disc. The motor shaft may be used for rotating the disc. The cycloid transmission also comprises an outer chain link ring that surrounds the disc. The outer chain link ring includes rollers that are inserted at given interfaces between links of the outer chain link ring. The rollers contact the disc as the disc rotates. The cycloid transmission also comprises a housing. The links of the outer chain link are coupled at the given interfaces. The rollers are inserted at the given interfaces and into the housing.

Claims (33)

1. A cycloid transmission comprising:

a disc;

a motor shaft attached to the disc, and for rotating the disc;

an outer chain link ring surrounding the disc, wherein the outer chain link ring includes rollers inserted at given interfaces between links of the outer chain link ring and the rollers contact the disc as the disc rotates, wherein the outer chain link ring includes a plurality of outer links and a plurality of inner links, wherein the rollers are inserted at given interfaces between the plurality of inner links of the outer chain link ring;

a plurality of pins connecting the plurality of outer links and the plurality of inner links; and

a housing, wherein the links of the outer chain link are coupled at the given interfaces, and the rollers are inserted at the given interfaces and into the housing, and wherein the housing comprises a plurality of slots for receiving respective pins of the plurality of pins and allowing for a relative position of the outer chain link ring to the disc to be adjusted.

2. The cycloid transmission of claim 1 , wherein the rollers are inserted at every other interface between links of the outer chain link.

3. The cycloid transmission of claim 1 , wherein the rollers are inserted at the given interfaces between links of the outer chain link ring based on a pattern other than insertion into every interface.

4. The cycloid transmission of claim 1 , wherein the rollers are inserted at every interface between links of the outer chain link ring.

5. The cycloid transmission of claim 1 , wherein the disc comprises an outer edge and a plurality of teeth along the outer edge for interfacing with the outer chain link.

6. The cycloid transmission of claim 1 , wherein the housing is circular, and comprises a channel to receive the outer chain link ring.

7. The cycloid transmission of claim 1 , wherein the housing comprises a channel to receive the outer chain link ring and the channel includes the plurality of slots where the plurality of pins are positioned.

8. The cycloid transmission of claim 1 , wherein the housing comprises a channel to receive the outer chain link ring and wherein the channel further comprises a fastener that couples a top of the channel to a bottom of the channel.

9. The cycloid transmission of claim 1 , wherein the plurality of pins protrudes from the plurality of outer links.

10. The cycloid transmission of claim 1 , wherein a given pin of the plurality of pins is inserted at every other slot of the plurality of slots.

11. The cycloid transmission of claim 1 , wherein respective pins are inserted through interfaces of the plurality of outer links and the plurality of inner links and into the housing.

12. A cycloid transmission comprising:

a disc concentric with a motor shaft operable to rotate the disc;

an outer chain link ring surrounding the disc, wherein the outer chain link ring includes a plurality of outer links and a plurality of inner links and wherein rollers are inserted at given interfaces between the plurality of inner links of the outer chain link ring and the rollers contact the disc as the disc rotates;

a plurality of pins connecting the plurality of outer links and the plurality of inner links; and

a housing comprising a plurality of slots for receiving respective pins of the plurality of pins and allowing for a relative position of the outer chain link ring to the disc to be adjusted.

13. The cycloid transmission of claim 12 , wherein the disc comprises an outer edge and a plurality of teeth along the outer edge for interfacing with the outer chain link.

14. The cycloid transmission of claim 12 , wherein the housing is circular, and comprises a channel to receive the outer chain link ring.

15. The cycloid transmission of claim 12 , wherein the housing comprises a channel to receive the outer chain link ring and the channel includes the plurality of slots where the plurality of pins are positioned.

16. The cycloid transmission of claim 12 , wherein the plurality of outer links are coupled at the given interfaces, and respective pins of the plurality of pins are inserted through the given interfaces and into the housing.

17. A cycloid transmission comprising:

a disc concentric with a motor shaft operable to rotate the disc;

an outer chain link ring surrounding the disc, wherein the outer chain link ring includes rollers inserted at given interfaces between links of the outer chain link ring and the rollers contact the disc as the disc rotates;

a plurality of pins connecting the links of the outer chain link ring; and

a housing comprising a plurality of slots for receiving respective pins of the plurality of pins and allowing for a relative position of the outer chain link ring to the disc to be adjusted.

18. The cycloid transmission of claim 17 , wherein the disc comprises an outer edge and a plurality of teeth along the outer edge for interfacing with the outer chain link.

19. The cycloid transmission of claim 17 , wherein the housing comprises a channel to receive the outer chain link ring and the channel includes the plurality of slots where the plurality of pins are positioned.

20. The cycloid transmission of claim 17 , wherein the plurality of outer links are coupled at the given interfaces, and respective pins are inserted through the given interfaces and into the housing.
