Abstract
A spring washer is disclosed for axially preloading anti-friction bearings. The spring washer can include an outer ring and an inner ring that is coaxially arranged with respect to the outer ring. An axis is defined by the two rings. Outer and inner rings are connected through several resilient connection rods. Resilient cantilevered rods can be provided which extend from one of the rings in between the connection rods and which have a free end at the opposite positioned ring. Thereby, the cantilevered rods can be axially bent up such that the free end has an axial offset.

Spring washer for axially preloading of anti-friction bearings, comprising:
- an outer ring;
- an inner ring coaxially arranged with respect to the outer ring;
- an axis defined by the inner and outer rings, wherein the outer ring and the inner ring are connected through resilient connection rods and wherein the outer ring and the inner ring are formed as short cylindrical tube sections and the tube sections have a length greater than a thickness of the material which forms the respective tube sections;
- and
- resilient cantilevered rods extending from one of the inner and outer rings in between the connection rods and having a free end at the other of the inner and outer rings, wherein the cantilevered rods are axially bent away from the inner and outer rings, such that the free end has an axial offset.
A spring washer in combination with a bearing block, the spring washer comprising:
- an outer ring;
- an inner ring coaxially arranged with respect to the outer ring;
- an axis defined by the inner and outer rings, wherein the outer ring and the inner ring are connected through several resilient connection rods;
- and
- resilient cantilevered rods extending from one of the inner and outer rings in between the connections rods and having a free end at the other of the inner and outer rings, wherein the cantilevered rods are axially bent away from the inner and outer rings, such that the free end has an axial offset;
- wherein the bearing block comprises:
- a stationary component;
- a shaft;
- and
- an anti-friction bearing in between, wherein an outer bearing ring of the anti-friction bearing is arranged at the stationary component and an inner bearing ring of the anti-friction bearing is arranged on the shaft, the anti-friction bearing being preloaded by the spring washer and wherein, the connection rods as well as the cantilevered rods, contribute to the preload on the anti-friction bearing.
A spring washer for axially preloading of anti-friction bearings, comprising:
- an outer ring;
- an inner ring coaxially arranged with respect to the outer ring;
- an axis defined by the inner and outer rings, wherein the outer ring and the inner ring are connected through resilient connection rods and wherein the outer ring and the inner ring are formed as short cylindrical tube sections;
- and
- resilient cantilevered rods extending from one of the inner and outer rings in between the connection rods and having a free end at the other of the inner and outer rings, wherein the cantilevered rods are axially bent away from the inner and outer rings, such that the free end has an axial offset;
- wherein free ends of the cantilevered rods have an extension which runs alongside the inner or outer ring adjacent to the free ends which are bent axially back to the inner or outer ring.
