Abstract

Claims (45)

1. A puller or installer tool for a bearing race comprising:

a draw plate defining a draw plate cam surface, a draw plate threaded central hole, and at least one threaded draw plate bolt hole;

a split ring defining at least one split plate cam surface, a split ring central opening, and a ring gap;

a cap plate defining a cap plate center hole and at least one cap plate bolt through hole;

at least one bolt member adapted to extend through the at least one cap plate bolt through hole and to engage the at least one threaded draw plate bolt hole; and

at least one rod defining a threaded end adapted to engage the draw plate threaded central hole; wherein

with the split ring arranged between the draw plate and the cap plate, the at least one bolt member is arranged to extend through the at least one cap plate bolt through hole, to extend through the split ring central opening, and to engage the at least one threaded draw plate bolt hole;

the at least one rod is arranged to extend through the cap plate center hole and the split ring central opening such that

the threaded end of the at least one rod engages the draw plate threaded central hole, and

the split ring is arranged such that the at least one split plate cam surface is in contact with the draw plate cam surface;

rotation of the at least one bolt member displaces the draw plate relative to the cap plate such that the draw plate cam surface engages the at least one split plate cam surface to deform the split ring to alter an effective diameter of the puller or installer tool by altering dimensions of the ring gap such that the split ring engages the bearing race; and

displacement of the rod displaces the split ring to displace the bearing race.

2. The puller or installer tool as recited in claim 1 , in which the split ring defines a surface configured to engage a portion of the bearing race.

3. The puller or installer tool as recited in claim 1 , in which the split ring defines a notch configured to engage a portion of the bearing race.

4. The puller or installer tool as recited in claim 1 , further comprising:

an anchor; wherein

the rod is supported for movement relative to the anchor; and

displacement of the rod relative to the anchor displaces the draw plate relative to the anchor.

5. The puller or installer tool as recited in claim 1 , further comprising:

an anchor, where the rod is supported for movement relative to the anchor;

and

a drive system for displacing the rod relative to the anchor; wherein operation of the drive system displaces the rod relative to the anchor to displace the draw plate relative to the anchor.

6. A tool assembly for installing a bearing race into or removing the bearing race from a wheel, the tool assembly comprising:

a draw plate defining a draw plate cam surface, a draw plate threaded central hole, and at least one threaded draw plate bolt hole;

a split ring defining at least one split plate cam surface, a split ring central opening, and a ring gap;

a cap plate defining a cap plate center hole and at least one cap plate bolt through hole;

at least one bolt member adapted to extend through the at least one cap plate bolt through hole and to engage the at least one threaded draw plate bolt hole; and

at least one rod defining a threaded end adapted to engage the draw plate threaded central hole; wherein

with the split ring arranged between the draw plate and the cap plate, the at least one bolt member is arranged to extend through the at least one cap plate bolt through hole, to extend through the split ring central opening, and to engage the at least one threaded draw plate bolt hole;

the at least one rod is arranged to extend through the cap plate center hole and the split ring central opening such that

the threaded end of the at least one rod engages the draw plate threaded central hole, and

the split ring is arranged such that the at least one split plate cam surface is in contact with the draw plate cam surface;

rotation of the at least one bolt member displaces the draw plate relative to the cap plate such that the draw plate cam surface engages the at least one split plate cam surface to deform the split ring to alter an effective diameter of the tool assembly by altering dimensions of the ring gap;

the split ring is sized and dimensioned to engage a portion of the bearing race when the split ring is deformed; and

displacement of the rod displaces the split ring to displace the bearing race.

7. The tool assembly as recited in claim 6 , in which the split ring defines surface a surface configured to engage a portion of the bearing race.

8. The tool assembly as recited in claim 6 , in which the split ring defines a notch configured to engage a portion of the bearing race.

9. The tool assembly as recited in claim 6 , further comprising:

an anchor adapted to engage the wheel;

the rod is supported for movement relative to the anchor; wherein

displacement of the rod relative to the anchor displaces the draw plate relative to the anchor.

10. The tool assembly as recited in claim 6 , further comprising:

an anchor adapted to engage the wheel, where the rod supported for movement relative to the anchor; and

a drive system for displacing the rod relative to the anchor; wherein

operation of the drive system displaces the rod relative to the anchor to displace the draw plate relative to the anchor.
