SEGMENTED ROTOR CAP ASSEMBLY
First Claim
1. A rotor cap assembly comprising:
- multiple rotor cap segments, each rotor cap segment having a front side, a back side, a rotor cap segment inner diameter, a rotor cap segment outer diameter, and positioning means on the back side of each rotor cap segment; and
a cap segment retainer configured to be engaged to a rotor through pre-existing fixing holes in the rotor, the cap segment retainer haying a back side and retaining means on a front side of the cap segment retainer, wherein the multiple rotor cap segments are disposed on the front side of the cap segment retainer, and wherein the retaining means engage the positioning means on the back side of each rotor cap segment such that the retaining means and the positioning means pilot the multiple cap segments at a rotor cap segment diameter.

Abstract
A rotor cap assembly has been conceived using multiple wedge-shaped rotor cap segments, in which the cap segments are disposed on a cap segment retainer and in which the cap segment retainer pilots the multiple rotor cap segments at a diameter intermediate the cap segments'"'"' outer diameter and the cap segments'"'"' middle diameter. By piloting multiple rotor cap segments with retaining means on the cap segment retainer and positioning means on the multiple cap segments, the rotor cap segments and cap segment retainer assembly may be fixed to a plate holder or directly to a rotor disc of a refiner without substantially altering either the plate holder or the rotor disc.

8. A rotor cap assembly comprising:
-
multiple rotor cap segments each rotor cap segment having; a front side, a back side, a rotor cap segment inner diameter, a rotor cap segment outer diameter, a rotor cap segment middle diameter located between the rotor cap inner diameter and the rotor cap outer diameter, and a protrusion extending from the back side, wherein the protrusion has a protrusion sidewall at a side of the protrusion; and a cap segment retainer configured to be engaged to a rotor through pre-existing holes in the rotor, the cap segment retainer having; a back side, a front side, a body, and a retaining lip extending from the front side of the cap segment retainer, wherein the retaining lip has a retaining lip sidewall at a side of the retaining lip, wherein a top of the retaining lip sidewall and the body of the cap segment retainer define a concave space, and wherein the protrusion is disposed within the concave space such that the protrusion sidewall contacts the retaining lip sidewall. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 24)

18. An annular rotor cap assembly comprising:
-
multiple rotor cap segments, each rotor cap segment having a front side, a back side, a rotor cap segment inner diameter, a rotor cap segment outer diameter, and a cap segment interlocking element; and a cap segment retainer engaging a rotor through pre-existing holes in the rotor, the cap segment retainer having a back side, a front side, and a retainer interlocking element, wherein the cap segment interlocking element engages the retainer interlocking element at a rotor cap segment diameter radially distal from the rotor cap segment inner diameter. - View Dependent Claims (19, 20, 21, 22, 23)
