Abstract

The present disclosure includes a wheel assembly having a tie bolt retention system. Tie bolt retention systems of the present disclosure include retention holes and retention elements. Retention elements may engage retention holes to prevent loosening or disengagement of a tie nut from the tie bolt.

First claim

What is claimed is:

1. A wheel assembly, comprising:
a first wheel section having a first outer surface, a first mate face, and a plurality of first bolt holes;
a second wheel section having a second outer surface, a second mate face, and a plurality of second bolt holes, wherein the second mate face is configured to contact and engage with the first mate face, and wherein the plurality of second bolt holes are configured to align with the plurality of first bolt holes;
a plurality of tie bolts each having a threaded end and a length sufficient to pass through a respective one of the plurality of first bolt holes and the plurality of second bolt holes, wherein the threaded end comprises a first retention hole and a second retention hole spaced apart from each other, wherein the first retention hole and the second retention hole each extend completely through the threaded end, wherein at least one of the first retention hole and the second retention hole of each tie bolt of the plurality of tie bolts is offset relative to a central longitudinal axis of the tie bolt;
a plurality of nuts each configured to engage with the threaded end of a respective one of the plurality of tie bolts; and
a single nut retention element extending through one of the first retention hole and the second retention hole of each tie bolt of the plurality of tie bolts.

2. The wheel assembly of claim 1 , wherein each tie bolt of the plurality of tie bolts passes from the first outer surface through a respective one of the plurality of first bolt holes of the first wheel section and through a respective one of the plurality of second bolt holes to protrude from the second outer surface of the second wheel section.

3. The wheel assembly of claim 2 , further comprising a first washer positioned between a head of the tie bolt and the first outer surface.

4. The wheel assembly of claim 3 , further comprising a second washer positioned between the second outer surface and the nut.

5. A tie bolt assembly, comprising:
a plurality of tie bolts, each tie bolt of the plurality of tie bolts having a threaded end and a length sufficient to pass through a first bolt hole and a second bolt hole, wherein the threaded end of the tie bolt comprises a first retention hole and a second retention hole spaced apart from each other, wherein the first retention hole and the second retention hole each extend completely through the threaded end and wherein at least one of the first retention hole or the second retention hole of each tie bolt of the plurality of tie bolts is offset relative to a central longitudinal axis of the tie bolt;
a plurality of nuts, each nut of the plurality of nuts configured to engage with the threaded end of a respective tie bolt of the plurality of tie bolts; and
a single nut retention element extending through one of the first retention hole and the second retention hole of a respective tie bolt of the plurality of tie bolts.

6. The tie bolt assembly of claim 5 , wherein the first retention hole and the second retention hole are offset relative to the central longitudinal axis of the tie bolt.

7. The tie bolt assembly of claim 5 , wherein each tie bolt of the plurality of tie bolts comprises a third retention hole.
