Abstract

The invention relates to a rotor block ( 1 ) comprising a housing ( 2 ) with at least one connection surface ( 3 A) that absorbs the load and pivot bearing seats ( 4 ) for plain and/or anti-friction bearings ( 5 ) that are designed to support a rotor ( 6 ). To dismount the rotor ( 6 ) from the housing ( 2 ), the plain and/or anti-friction bearings ( 5 ) can be dismantled from the exterior and the rotor ( 6 ) from a side ( 8 ) lying transversally to the bearings. The pivot bearing seats ( 4 ) take the form of recesses ( 9 ) that are directly configured in the housing wall, without the use of annular bodies. To facilitate the mounting and dismounting processes and to improve the precision of the rotor alignment, the pivot bearing seats ( 4 ) are configured in such a way that they form a segment greater than a semi-circle around the plain and/or anti-friction bearings ( 5 ), leaving a section open on one side ( 8 ) in relation to said bearings ( 5 ), thus forming a narrowing ( 13 ).

Claims (33)

1. 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.

2. The rotor block per claim 1 , wherein the openings are free at the side, wherein the rotor is taken out from the downward side after the at least one of plain bearings and anti-friction bearings are removed sideways.

3. The rotor block per claim 1 , wherein the openings have a cross-sectional shape resembling a keyhole.

4. The rotor block per claim 1 , wherein the at least one connection surface is a top connection surface.

5. The rotor block per claim 1 , wherein the openings are free at the downward side, wherein the rotor is taken out from the downward side after the at least one of plain bearings and anti-friction bearings are removed sideways.

6. The rotor block per claim 5 , wherein the openings have a cross-sectional shape resembling a keyhole.

7. The rotor block per claim 6 , wherein the openings have circular upper regions to accommodate the at least one of plain bearings and anti-friction bearings.

8. The rotor block per claim 7 , wherein the openings have a lower region forming an angle, the angle being open to the side and joined to the circular upper regions at the narrowings.

9. The rotor block per claim 8 , wherein a cross section of the circular upper regions of the openings comprises approximately three quarters of a circle.

10. The rotor block per claim 8 , wherein the at least one connection surface is a top connection surface.

11. A rotor block, comprising:

a housing 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 perpendicularly 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 circular upper regions that form segments greater than a semicircle 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 open sections formed at a narrowing of the openings, wherein the circular upper regions of the openings accommodate the at least one of plain bearings and anti-friction bearings, and wherein the open sections form an angle, the angle being open to the downward side and joined to the circular upper regions at the narrowings.

12. A rotor block, comprising:

a housing 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 perpendicularly 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 circular upper regions that form segments greater than a semicircle 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 open sections formed at a narrowing of the openings, wherein the circular upper regions of the openings accommodate the at least one of plain bearings and anti-friction bearings, and wherein a cross section of the circular upper regions of the openings comprises approximately three quarters of a circle.

13. A rotor block, comprising:

a housing having a plurality of housing walls and at least one connection surface, the at least one connection surface adapted to absorb a load;

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 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 perpendicularly downward side of the housing transverse to the bearings to dismount the rotor from the housing;
