Abstract

A mass damper system has a damper mass carrier and a damper mass movably received at the damper mass carrier a lubricant supply, a lubricant collector, and a lubricant distributor radially offset to one another with the damper mass carrier, the lubricant supply arranged at a shorter radial distance from a central axis than the lubricant collector, and the lubricant distributor arranged at a greater radial distance from the central axis than the lubricant collector to collect lubricant supplied by the lubricant supply and to guide the lubricant through the lubricant distributor to the damper mass. A stop arrangement limits a deflection path of the damper mass relative to the damper mass carrier, and the lubricant distributor has a lubricant feed that leads from the lubricant collector to a constructional unit requiring intensive lubrication.

First claim

The invention claimed is:

1. A mass damper system comprising:
at least one damper mass
at least one damper mass carrier configured to moveably receive the at least one damper mass;
a lubricant collector;
a lubricant supply arranged at a shorter radial distance from a central axis than the lubricant collector; and
a lubricant distributor arranged at a greater radial distance from a central axis than the lubricant collector and configured to collect, via the lubricant collector, lubricant supplied by the lubricant supply with assistance of centrifugal force and to guide the lubricant through the lubricant distributor at least to the at least one damper mass;
wherein the lubricant collector, the lubricant supply, and the lubricant distributor are associated radially offset to one another with the at least one damper mass carrier;
an association with a stop arrangement, at least for the lubricant collector, configured to limit a deflection path of the at least one damper mass relative to the at least one damper mass carrier; and
at least one lubricant feed of the lubricant distributor that leads from the lubricant collector to at least one selected constructional unit requiring intensive lubrication and which, adjoining an extension area, opens into this selected constructional unit requiring intensive lubrication.

2. The mass damper system according to claim 1 , wherein the at least one lubricant feed of the lubricant distributor comprises:
at least one lubricant input provided substantially radially outside of the lubricant collector; and
at least one lubricant output provided substantially radially outside of the at least one lubricant input and substantially radially inside of at least one selected constructional unit requiring intensive lubrication.

3. The mass damper system according to claim 1 , wherein
the lubricant collector substantially annularly surrounds the central axis and has at least one lubricant collecting space which has at the radial side of the lubricant collector remote of the at least one damper mass at least one opening configured to allow lubricant to access the lubricant collecting space; and
the at least one lubricant collecting space is provided with at least one lubricant passage configured to allow lubricant collected inside of the lubricant collecting space to flow out into at least one lubricant input of the at least one lubricant feed of the lubricant distributor.

4. The mass damper system according to claim 3 , wherein the lubricant collector has at its radial side facing the at least one damper mass one of:
a covering wall with which an at least substantially radially inwardly extending radial wall or
a damper mass carrier element is associated on at least one axial side to form the lubricant collecting space.

5. The mass damper system according to claim 4 , wherein the stop arrangement for the at least one damper mass is provided radially inside the at least one damper mass, wherein the stop arrangement encloses the central axis in a ring-shaped manner and is fastened to the two damper mass carrier elements or by spacers that pass through eyelets of the stop arrangement.

6. The mass damper system according to claim 4 , wherein the one of the covering wall and/or the at least one radial wall and/or the damper mass carrier element are provided with at least one lubricant passage.

7. The mass damper system according to claim 6 , wherein the at least one covering wall and/or the at least one radial wall of the lubricant collector have at least one circumferential break in circumferential direction serving as lubricant passage.

8. The mass damper system according to claim 4 with a damper mass carrier having a respective damper mass carrier element axially at both sides of the at least one damper mass, wherein the lubricant collector has at its radial side facing the at least one damper mass a respective covering wall which is provided at its radial inner side in circumferential direction with at least one area which has within its axial extension area an area with a greatest extension radially inward and, from there, in axial direction to the respective adjacent damper mass carrier element, undergoes a reduction of the extension radially inward.

9. The mass damper system according to claim 8 , wherein the at least one covering wall of the lubricant collector has in circumferential direction at least one axial reduction serving as lubricant passage and accordingly forming the at least one lubricant input of the at least one lubricant feed of the lubricant distributor.

10. The mass damper system according to claim 8 ,
wherein the covering wall of the lubricant collector is formed in a substantially arrow-shaped manner at its radial inner side in axial direction,
wherein the substantially axial central area has a greatest radial extension radially inward and, from the location of the greatest radial extension in axial direction to the respective damper mass carrier element, undergoes a reduction of the extension radially inward.

11. The mass damper system according to claim 8 ,
wherein the covering wall of the lubricant collector is formed substantially convex at its radial inner side in axial direction,
wherein the substantially axial central area has a greatest radial extension radially inward and, from the location of the greatest radial extension in axial direction to the respective damper mass carrier element, undergoes a reduction of the extension radially inward.

12. The mass damper system according to claim 8 ,
wherein the covering wall of the lubricant collector is formed at least substantially concave at its radial inner side in axial direction,
wherein substantially an axial area that is at the farthest distance from the adjacent damper mass carrier element has a greatest radial extension radially inward and, from the location of the greatest radial extension in axial direction to the damper mass carrier element, undergoes a reduction of the extension radially inward.

13. The mass damper system according to claim 12 , wherein the damper mass carrier receives at least one damper mass in each instance axially on both sides, and the lubricant collector in association with at least one of the damper masses has at least one lubricant collector component.

14. The mass damper system according to claim 13 , wherein at least one of the lubricant collector component and the damper mass carrier are provided at the side facing the respective other one of these two constructional unit, such that the lubricant collector component or the damper mass carrier, with at least one axial reduction serving as lubricant passage forms the at least one lubricant input of the at least one lubricant feed of the lubricant distributor.

15. The mass damper system according to claim 8 , wherein the respective damper mass carrier element has at its side facing the at least one damper mass at least one axial reduction serving as lubricant passage and accordingly forming the lubricant output and/or an axial reduction serving as lubricant passage and accordingly forming the lubricant output of the lubricant feed of the lubricant distributor.
