Abstract

A gear mechanism component having a holder for mounting a component, a lubricant carrier which is infused with a lubricant being pressed into the holder, a gear mechanism arrangement having the gear mechanism component and the component, an adjusting drive having the gear mechanism arrangement, and a method for assembling the gear mechanism arrangement.

First claim

What is claimed is:

1. A gear mechanism component ( 2 ) comprising
a holder ( 2 . 1 ) configured to be a bearing point ( 50 ) for mounting a second component ( 5 ), and
a lubricant carrier ( 6 ) which is infused with a lubricant and which is pressed into the holder ( 2 . 1 ),
wherein the gear mechanism component ( 2 ) is a planetary carrier ( 2 ) of a planetary gear mechanism arrangement ( 10 ), and
wherein the gear mechanism component ( 2 ) has a side ( 2 . 2 ) which faces the second component ( 5 ) when the second component ( 5 ) is mounted in the gear mechanism component ( 2 ), and
wherein the lubricant carrier ( 6 ) is arranged in the holder ( 2 . 1 ) on the side ( 2 . 2 ) which faces the second component ( 5 ) when the second component ( 5 ) is mounted in the gear mechanism component ( 2 ) such that the lubricant carrier ( 6 ) is displaced when the second component ( 5 ) is pushed into the gear mechanism component ( 2 ).

2. The gear mechanism component ( 2 ) according to claim 1 , wherein when the lubricant carrier ( 6 ) is arranged in the holder ( 2 . 1 ) on the side ( 2 . 2 ) which faces the second component ( 5 ) when the second component ( 5 ) is mounted in the gear mechanism component ( 2 ), the lubricant carrier ( 6 ) is arranged in a delivery state (A).

3. The gear mechanism component ( 2 ) according to claim 2 , characterized in that, when in the delivery state (A), the lubricant carrier ( 6 ) is arranged in the holder ( 2 . 1 ) flush with the side ( 2 . 2 ) which faces the second component.

4. The gear mechanism component ( 2 ) according to claim 1 , characterized in that the lubricant carrier ( 6 ) is a felt or a sponge.

5. The gear mechanism component ( 2 ) according to claim 1 , characterized in that the gear mechanism component ( 2 ) is sintered and oil-impregnated.

6. The gear mechanism component ( 2 ) according to claim 1 , characterized in that the holder ( 2 . 1 ) is a bore.

7. A planetary gear mechanism arrangement ( 10 ) in an assembled state (M), the planetary gear mechanism arrangement ( 10 ) comprising a planetary carrier ( 2 ) and a second component ( 5 ), the planetary carrier ( 2 ) including a holder ( 2 . 1 ) in which the second component ( 5 ) is mounted, and the planetary carrier ( 2 ) including a lubricant carrier ( 6 ) which is infused with a lubricant and which is pressed into the holder ( 2 . 1 ), wherein the planetary carrier ( 2 ) has a side ( 2 . 2 ) facing the second component ( 5 ), wherein the lubricant carrier ( 6 ) is arranged, when in a delivery state (A), in the holder ( 2 . 1 ) on the side ( 2 . 2 ) facing the second component ( 5 ) such that the lubricant carrier ( 6 ) is displaced when the second component ( 5 ) is pushed into the planetary carrier ( 2 ).

8. The planetary gear mechanism arrangement ( 10 ) according to claim 7 , characterized in that the second component ( 5 ) has a bearing journal ( 5 . 1 ) which is configured to be pushed into the holder ( 2 . 1 ) in an axial direction ( 71 ).

9. The planetary gear mechanism arrangement ( 10 ) according to claim 8 , characterized in that the lubricant carrier ( 6 ) is arranged behind the bearing journal ( 5 . 1 ) in an axial direction ( 71 ).

10. The planetary gear mechanism arrangement ( 10 ) according to claim 8 , characterized in that, when in the delivery state (A), the lubricant carrier ( 6 ) is arranged on the side ( 2 . 2 ) of the planetary carrier ( 2 ) facing the second component ( 5 ) in such a way that the bearing journal ( 5 . 1 ) comes into contact with the lubricant carrier ( 6 ) when pushed into the holder ( 2 . 1 ).

11. The planetary gear mechanism arrangement ( 10 ) according to claim 8 , characterized in that the bearing journal ( 5 . 1 ) is mounted in the holder ( 2 . 1 ) and bears against the lubricant carrier ( 6 ).

12. The planetary gear mechanism arrangement ( 10 ) according to claim 7 , characterized in that, when in the delivery state (A), the lubricant carrier ( 6 ) is arranged on the side ( 2 . 2 ) of the planetary carrier ( 2 ) which faces the second component ( 5 ) in such a way that the second component ( 5 ) comes into contact with the lubricant carrier ( 6 ) when pushed into the holder ( 2 . 1 ).

13. The planetary gear mechanism arrangement ( 10 ) according to claim 7 , wherein the second component ( 5 ) bears against the lubricant carrier ( 6 ).

14. A tailgate drive having the planetary gear mechanism arrangement ( 10 ) according to claim 7 .

15. A method for assembling the planetary gear mechanism arrangement ( 10 ) according to claim 7 , having the following steps:
pressing the lubricant carrier ( 6 ) into the holder ( 2 . 1 ) in or counter to an axial direction ( 71 ), with the result that the said lubricant carrier ( 6 ) is arranged on the side ( 2 . 2 ) of the planetary carrier ( 2 ) which faces the second component ( 5 ), and
pushing the second component ( 5 ) into the holder ( 2 . 1 ) in the axial direction ( 71 ), the second component ( 5 ) displacing the lubricant carrier ( 6 ) in the axial direction ( 71 ).

16. The planetary gear mechanism arrangement ( 10 ) according to claim 7 , characterized in that the holder ( 2 . 1 ) is a bore.
