Patent ID: 7766551

Claim:
A rotor block, comprising: a housing, the housing being a single piece and generally box-shaped, and having a plurality of housing walls and at least one connection surface, the at least one connection surface adapted to absorb a load; and a plurality of axially extending pivot bearing seats formed by the housing for receiving at least one of plain bearings and anti-friction bearings, the bearings being designed to support a rotor having a hub, wherein the seats are generally the width of the bearings, and wherein the at least one of plain bearings and antifriction bearings are slidably dismantled from the rotor hub axially from an exterior of the housing and the rotor is dismantled from open sections at a downward side of the housing transverse to the bearings to dismount the rotor from the housing; wherein the plurality of pivot bearing seats form openings directly configured in respective ones of the housing walls, without the use of annular bodies, wherein the plurality of pivot bearing seats have upper regions that form segments around the at least one of plain bearings and anti-friction bearings and lower regions that form the open sections for dismantling the rotor in relation to the bearings, the segments being greater than a semicircle, the open sections formed at a narrowing of the openings that is larger than a diameter of the hub of the rotor, wherein the open sections are pointing perpendicularly downward; and wherein the at least one of plain bearings and anti-friction bearings are smaller than the segments and larger than the open sections.
