SEGMENTED ROTOR CAP ASSEMBLY

摘要

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.

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.
