Abstract

A follower assembly of a cam assembly for a harvester reel including a baffle, a compressible member adjacent the baffle, and a roller spacer adjacent the compressible member. The follower assembly further includes a tubular cam follower housing the roller spacer, and a fastener extending through the tubular cam follower, the roller spacer, the compressible member and the baffle. The resultant follower assembly provides a construction which minimizes peening of the baffle, whereby the fastener maintains its clamp load such that the cam followers maintain engagement with the cam track and the potential for breakage of the fastener is minimized.

First claim

I claim:

1. A follower assembly of a cam assembly for a harvester reel comprising
a baffle;
a compressible member contacting the baffle;
a roller spacer mounted to the baffle and having an annular flange biasing the compressible member against the baffle, whereby the baffle circumscribes the roller spacer;
a tubular cam follower surrounding the roller spacer; and
a fastener extending through the tubular cam follower, the roller spacer, the compressible member and the baffle.

2. The follower assembly of claim 1 , further comprising a bracket adjacent the baffle, and wherein the fastener extends through the bracket.

3. The follower assembly of claim 2 , further comprising a crank plate adjacent the bracket, and another fastener extending through the crank plate.

4. The follower assembly of claim 3 , further comprising a support member extending from the crank plate.

5. The follower assembly of claim 1 , wherein the roller spacer includes:
an annular body.

6. The follower assembly of claim 5 , wherein the compressible member circumscribes the annular body.

7. The follower assembly of claim 1 , wherein the annular flange has an overall diameter larger than an inner diameter of the compressible member.

8. The follower assembly of claim 5 , wherein the baffle includes a through hole and the annular body is seated within the through hole.

9. The follower assembly of claim 1 , wherein the fastener secures the tubular cam follower, the roller spacer, the compressible member and the baffle together.

10. The follower assembly of claim 1 , wherein the fastener compressingly engages the tubular cam follower, the roller spacer, the compressible member and the baffle together.

11. The follower assembly of claim 1 , wherein the baffle comprises low carbon, non-hardened steel or plastic.

12. The follower assembly of claim 1 , wherein the compressible member is a Belleville washer.

13. A cam assembly for a harvester reel comprising the follower assembly of claim 1 .

14. The cam assembly of claim 13 , further comprising a second follower assembly of claim 1 .

15. The cam assembly of claim 13 , further comprising a cam track, wherein the follower assembly engages the cam track.

16. A harvester reel for an agricultural harvester comprising the cam assembly of claim 13 .

17. The harvester reel of claim 16 , further comprising a reel assembly including:
a central rotating shaft, and
a plurality of support members extending widthwise across the reel assembly and connected to a central rotating shaft for rotation therewith.

18. The follower assembly of claim 1 , wherein the compressible member is between the roller spacer and the baffle.

19. The follower assembly of claim 1 , wherein the compressible member is between the annular flange and the baffle.

20. The follower assembly of claim 1 , further comprising a bracket adjacent the baffle, wherein the roller spacer abuts the bracket.
