Abstract

The disclosure provides an adapter assembly of a generator and an axle-end generator assembly. An adapter assembly includes a first part configured to mount to a wagon bogie and a second part connecting to the first part. The first part and the second part are configured to form a base for mounting a stator of a generator together.

First claim

What is claimed is:

1. An axle-end generator assembly comprising:
an adapter assembly comprising a first part configured to mount to a wagon bogie and a second part connecting to the first part, the first part and the second part together being configured to form a base for mounting a stator of a generator;
a rotor mounted to an end of an axle; and
the stator mounted to both the first part and the second part at four corners of an end surface of the adapter assembly in an axial direction.

2. The axle-end generator assembly according to claim 1 , wherein the first part and the second part are connected to each other with end portions thereof contacting to each other.

3. The axle-end generator assembly according to claim 1 , wherein the first part and the second part are connected to each other by members selected from the group consisting of a screw, a bolt, a fastener, a rivet, or a hoop.

4. The axle-end generator assembly according to claim 1 further comprising bars, wherein the first part and the second part are connected to each other through the bars.

5. The axle-end generator assembly according to claim 4 , wherein the bars and the first part or the second part are formed as one single piece, and the bars extend from the first part or the second part toward the second part or the first part.

6. The axle-end generator assembly according to claim 4 , wherein the bars are mounted to the first part or the second part by a member selected from the group consisting of a screw, a bolt, a fastener, or a rivet.

7. The axle-end generator assembly according to claim 1 , wherein the first part and the second part are connected to each other directly.

8. The axle-end generator assembly according to claim 1 , wherein the first part and the second part are connected to each other indirectly.

9. The axle-end generator assembly according to claim 1 , wherein the stator is mounted to the adapter assembly by members selected from the group consisting of a screw, a bolt, a fastener, or a rivet.

10. The axle-end generator assembly according to claim 9 , wherein the stator is mounted to the first part and the second part by the members.

11. The axle-end generator assembly according to claim 1 , wherein a first number of first mounting points between the first part and the stator is equal to a second number of second mounting points between the second part and the stator.

12. The axle-end generator assembly according to claim 1 , wherein first mounting points between the first part and the stator and second mounting points between the second part and the stator are disposed symmetrically.

13. The axle-end generator assembly according to claim 1 , wherein mounting points between the stator and the adapter assembly are evenly disposed around the axle.

14. The axle-end generator assembly according to claim 1 , wherein the axle-end generator assembly further comprises
a backing ring and seal wear rings, and
a bearing disposed between the adapter assembly and the axle, wherein the backing ring, the seal wear rings and the rotor fix the bearing along the axle.

15. The axle-end generator assembly according to claim 14 , wherein the backing ring, the seal wear rings and the rotor fix an inner ring of the bearing, and an outer ring of the bearing fixes the adapter assembly.

16. The axle-end generator assembly according to claim 1 , wherein the rotor has a shape of disc, and the stator faces the rotor in an axial direction.

17. The axle-end generator assembly according to claim 1 , wherein the first part is mounted to the wagon bogie at an upper side of the axle, and the second part is connected to the first part by screws at a lower side of the axle.

18. An axle-end generator assembly comprising:
an adapter assembly comprising a first part configured to mount to a wagon bogie and a second part connecting to the first part, the first part and the second part together being configured to form a base for mounting a stator of a generator;
a rotor mounted to an end of an axle; and
the stator mounted to both the first part and the second part, wherein a first number of first mounting points between the first part and the stator is equal to a second number of second mounting points between the second part and the stator.

19. An axle-end generator assembly comprising:
an adapter assembly comprising a first part configured to mount to a wagon bogie and a second part connecting to the first part, the first part and the second part together being configured to form a base for mounting a stator of a generator;
a rotor mounted to an end of an axle; and
the stator mounted to both the first part and the second part, wherein first mounting points between the first part and the stator and second mounting points between the second part and the stator are disposed symmetrically.
