Abstract

The invention relates to a vibration elimination system, comprising a shielding plate (2) for a motor component, at least one vibration elimination element (10) that is fastened to the shielding plate (2), wherein each vibration damping element (10) comprises a spring-mass system that is capable of vibration, the spring force and mass of which are dimensioned such that said spring-mass system is matched to a predetermined vibration frequency of the shielding plate (2).

Claims

1. A vibration elimination system, comprising

a shielding plate (2) for a motor component,

at least one vibration elimination element (10), which is

fastened to the shielding plate (2),

wherein each vibration elimination element (10) comprises a spring-mass system that is capable of vibration, the spring force and mass of which are dimensioned such that said spring-mass system is matched to a predetermined vibration frequency of the shielding plate (2).

2. The vibration elimination system according to claim 1, wherein at least one vibration elimination element (10) is fastened in a region of maximum vibration deflection of the shielding plate (2).

3. The vibration elimination system according to claim 1 or 2, wherein a plurality of vibration elimination elements (10) are fastened at a predetermined distance around a region of maximum vibration deflection of the shielding plate (2).

4. The vibration elimination system according to one of the preceding claims, wherein at least two vibration elimination elements (10) are mounted on the shielding plate (2), which are matched to different vibration frequencies.

5. The vibration elimination system according to one of the preceding claims, wherein at least one vibration elimination element (10) is matched such that it shifts an initial vibration frequency of the shielding plate into a predetermined frequency range.

6. The vibration elimination system according to one of the preceding claims, wherein at least one vibration elimination element (10) is matched such that it damps a predetermined vibration frequency of the shielding plate.

7. The vibration elimination system according to one of the preceding claims, wherein the vibration elimination element (10) comprises an elastic casing (14) which provides the spring force of the spring-mass system, and a metallic oscillation mass (16), which is mounted in a manner capable of vibration in the elastic casing (14).

8. The vibration elimination system according to one of claims 1 to 6, wherein the vibration elimination element (10) comprises a metallic oscillation mass (16), which is mounted in a manner capable of vibration between two elastic elements (24), which provide the spring force of the spring-mass system.

9. The vibration elimination system according to claim 7 or 8, wherein the spring-mass system is surrounded at least partially by a fixed casing (18).

10. The vibration elimination system according to one of claims 7 to 9, wherein during operation the oscillation mass (16) is capable of vibration parallel to the deflection direction of the region of the shielding plate (2), in which the vibration elimination element (10) is mounted.
