Archery bow with limb spacing adjustment
In some embodiments, an archery bow comprises a limb assembly comprising a first limb and a second limb, the second limb comprising limb threads. An axle assembly is supported by the first limb and the second limb. The axle assembly comprises an axle comprising axle threads. A first connection between the axle assembly and the first limb comprises a fixed connection. A second connection between the axle assembly and the second limb comprises the limb threads engaged with the axle threads. Rotation of the axle with respect to the limb assembly adjusts a distance between the first limb and the second limb.
1. An archery bow comprising:
a limb assembly comprising a first limb and a second limb, the second limb comprising limb threads;
an axle assembly supported by the first limb and the second limb, the axle assembly comprising an axle comprising axle threads;
a first connection between the axle assembly and the first limb, the first connection comprising a fixed connection that excludes helical threads oriented between the first limb and the axle; and
a second connection between the axle assembly and the second limb, the second connection comprising the limb threads engaged with the axle threads;
wherein rotation of the axle with respect to the limb assembly adjusts a distance between the first limb and the second limb.
2. The archery bow of claim 1 , wherein rotation of the axle with respect to the limb assembly moves the second limb along a length of the axle but does not move the first limb along the length of the axle.
3. The archery bow of claim 1 , the axle assembly comprising a fastener assembly attached to the axle, the fastener assembly abutting the first limb.
4. The archery bow of claim 3 , the fastener assembly comprising a fastener and a washer, the fastener engaging the axle, the washer abutting the first limb.
5. The archery bow of claim 1 , the second connection comprising a locking mechanism arranged to prevent the axle from rotating with respect to the second limb.
6. The archery bow of claim 5 , the locking mechanism comprising a fastener arranged to apply a force between the axle and the second limb.
7. The archery bow of claim 1 , the axle comprising a flange arranged to locate a rotatable member.
8. The archery bow of claim 7 , comprising a roller bearing in contact with the flange.
9. The archery bow of claim 8 , comprising a spacer surrounding the axle, the spacer abutting the roller bearing, the spacer in compression along its length.
10. The archery bow of claim 1 , the first limb comprising a first bracket, the axle assembly abutting the first bracket.
11. The archery bow of claim 10 , the second limb comprising a second bracket, the second bracket comprising the limb threads.
12. An archery bow comprising:
a limb assembly comprising a first limb and a second limb, the first limb comprising a first bracket, the second limb comprising a second bracket, the second bracket comprising limb threads;
an axle assembly supported by the first limb and the second limb, the axle assembly abutting the first bracket, the axle assembly comprising an axle comprising axle threads;
a first connection between the axle assembly and the first limb, the first connection comprising a fixed connection; and
a second connection between the axle assembly and the second limb, the second connection comprising the limb threads engaged with the axle threads;
wherein rotation of the axle with respect to the limb assembly adjusts a distance between the first limb and the second limb;
the axle comprising a marking, the marking visible through a window in the second bracket.
13. An archery bow comprising:
a first limb comprising a first bracket;
a second limb comprising a second bracket, the second bracket comprising a window and bracket threads;
an axle comprising a first portion, a second portion and a marking, the first portion attached to the first bracket, the second portion comprising axle threads engaged with the bracket threads, the marking visible through the window;
wherein rotation of the axle with respect to the second bracket adjusts a distance between the first bracket and the second bracket.
14. The archery bow of claim 13 , further comprising a rotatable member supported by the axle.
15. The archery bow of claim 14 , wherein the axle comprises a flange, the rotatable member abutting the flange.
16. The archery bow of claim 14 , further comprising a bearing oriented between the first bracket and the axle.
17. The archery bow of claim 16 , wherein the rotatable member contacts the bearing.
