Abstract

A mounting assembly secures a generator and facilitates attachment to a railroad railcar on the end of the railcar axle. The generator produces electricity from the axle of a railroad railcar while it is traveling on a railroad track. A generator is mounted with a generator bracket and a backing plate to an existing bearing adapter on the railcar. A drive hub engages axle bolts on the railcar axle. As the railcar axle turns, the drive hub turns and with the drive hub connected to a generator the generator subsequently rotates to supply electricity to the railcar. Different types of generators can be attached with the mounting assembly to the railcar. The mounting assembly allows generators to be mounted without modification to the existing railcar structure.

Claims

1. A generator mounting assembly for holding a generator adjacent to a first end of an axle, the generator mounted in relation to the axle so as to receive rotational energy from the axle as it rotates, the generator mounting assembly attached to a bearing adapter, the bearing adapter being disposed between a bearing and a sideframe, the generator producing electricity as the axle rotates comprising:

a generator bracket connected adjacent to a first side of the bearing adapter, the generator connected to the generator bracket;

a backing plate connected adjacent to a second side of the bearing adapter;

fastening means connecting the generator bracket and the backing plate to the bearing adapter, the fastening means holding the generator mounting assembly to the bearing adapter;

a drive hub connected to the generator, the drive hub adapted to engage the first end of the axle such that as the axle rotates the drive hub rotates and turns the generator.

2. The generator mounting assembly of claim 1 further comprising:

a generator shaft attached to the generator;

a flexible shaft coupling connected between the drive hub and the generator shaft, the flexible shaft coupling allowing engagement between the generator shaft and the first end of the axle when a first axis of rotation of the generator shaft is different than a second axis of rotation of the axle.

3. The generator mounting assembly of claim 1 further comprising:

the generator bracket having a first slot;

the backing plate having a second slot;

the bearing adapter having a first and a second projection, the first projection mating with the first slot and the second projection mating with the second slot.

4. The generator mounting assembly of claim 1 in which the fastening means is a first bolt and a second bolt.

5. The generator mounting assembly of claim 1 in which the drive hub has a plurality of yokes for engaging the first end of the axle, the yokes designed to allow engagement between a generator shaft connected to the generator and the first end of the axle when a first axis of rotation of the generator shaft is different than a second axis of rotation of the axle.

6. The generator mounting assembly of claim 1 in which the axle is a railroad car axle.

7. The generator mounting assembly according to claim 5 further comprising:

a plurality of axle bolts, the axle bolts connected to the first end of the axle, the yokes engaging the axle bolts.

8. A generator mounting assembly, the generator mounting assembly attached in relation to a first end of an axle so as to receive rotational energy from the axle as it rotates, the generator mounting assembly attached to a bearing adapter, the bearing adapter being disposed between a bearing and a sideframe, comprising:

a generator bracket connected adjacent to a first side of the bearing adapter;

a generator connected to the generator bracket;

a backing plate connected adjacent to a second side of the bearing adapter;

fastening means connecting the generator bracket and the backing plate to the bearing adapter, the fastening means holding the generator mounting assembly to the bearing adapter;

a drive hub connected to the generator, the drive hub adapted to engage the first end of the axle such that as the axle rotates the drive hub rotates and turns the generator, the generator producing electricity as the axle rotates.

9. The generator mounting assembly of claim 8 further comprising:

a generator shaft attached to the generator;

a flexible shaft coupling connected between the drive hub and the generator shaft, the flexible shaft coupling operable to allow engagement between the generator shaft and the first end of the axle when a first axis of rotation of the generator shaft is different than a second axis of rotation of the axle.

10. The generator mounting assembly of claim 8 further comprising:

the generator bracket having a first slot;

the backing plate having a second slot;

the bearing adapter having a first and a second projection, the first projection mating with the first slot and the second projection mating with the second slot.

11. The generator mounting assembly of claim 8 in which the fastening means is a first bolt and a second bolt.

12. The generator mounting assembly of claim 8 in which the drive hub has a plurality of yokes for engaging the first end of the axle, the yokes designed to allow engagement between a generator shaft connected to the generator and the first end of the axle when a first axis of rotation of the generator shaft is different than a second axis of rotation of the axle.

13. The generator mounting assembly of claim 8 in which the axle is a railroad car axle.

14. The generator mounting assembly according to claim 12 further comprising:

a plurality of axle bolts, the axle bolts connected to the first end of the axle, the yokes engaging the axle bolts.

15. A generator mounting assembly for holding a generator adjacent to a first end of an axle held in place by a bearing and a sideframe, the generator mounted in relation to the axle so as to receive rotational energy from the axle as it rotates, and to produce electricity as the axle rotates, the mounting assembly comprising:
