Abstract

The invention relates to a machine, in particular a generator, which has a bearing (19) supported on a hub (22), whereby a bearing part of the bearing (19) is loaded by a spring element (25) producing an axial force (FA). The spring element (25) is plastically deformed.

Claims

1. A machine, in particular a generator, is disclosed, with a bearing (19) supported in a hub (22), whereby a bearing part of the bearing (19) is loaded by a spring element (25) producing an axial force (FA),

whereby the spring element (25) is plastically deformed.

2. The machine as recited in claim 1,

wherein the spring element (25) has a spring constant between 18 and 70 N/m in the plastic range.

3. The machine as recited in claim 1, wherein the plastic range begins after an elastic compression travel Δ

se between 2 and 3.5 mm.

4. The machine as recited in claim 2,

wherein a change in axial force Δ

FA of 100 N is capable of being adjusted in a plastic compression travel between 1.5 mm and 3.5 mm.

5. The machine as recited in claim 1, wherein the spring element (25) acts with an axial force FA between 350 N and 650 N.

6. The machine as recited in claim 1, wherein the spring element (25) is centered by the hub (22).

7. The machine as recited in claim 1, wherein the spring element (25) has a carrier region (52), from which at least one spring arm (55) extends.

8. The machine as recited in claim 7,

wherein the at least one spring arm (55) extends in the peripheral direction.

9. The machine as recited in claim 1, wherein cross sections of the spring element (25) loaded with the axial force are exposed to essentially identical mechanical loads.

10. The machine as recited in claim 1, wherein the bearing (19) is a movable bearing.
