Abstract

A torque motor assembly includes a shell which has a first wall and a second wall which defines a cavity. A torque motor is positioned at least partially within the cavity. At least one compliant pad is positioned between the first wall and the torque motor and is configured to trap at least one wire within the shell. A housing for a torque motor and a method of assembling a torque motor assembly are also disclosed.

First claim

What is claimed is:

1. A torque motor assembly, comprising:
a shell having a first wall and a second wall defining a cavity;
a torque motor positioned at least partially within the cavity;
at least one compliant pad positioned between the first wall and the torque motor and configured to trap at least one wire within the shell, wherein the at least one compliant pad is configured to be inert with respect to the at least one wire.

2. The assembly of claim 1 , wherein the at least one wire includes a solder joint.

3. The assembly of claim 1 , wherein the at least one compliant pad is configured to damp vibratory loads.

4. The assembly of claim 1 , wherein the at least one compliant pad is formed from a rubber sponge material.

5. The assembly of claim 1 , wherein at least one complaint pad is a first pad, and further comprising a second pad.

6. The assembly of claim 5 , wherein the first pad is annular in shape, wherein the second pad has a central opening configured to receive the at least one wire therethrough.

7. The assembly of claim 5 , wherein the first pad includes at least one slot configured to receive the at least one wire.

8. The assembly of claim 7 , wherein the second pad is annular in shape, and wherein a slot of the at least one slot extends across the radial extent of the second pad, and is configured to receive the at least one wire from a central opening of the second pad.

9. The assembly of claim 7 , wherein the second pad is annular in shape, and wherein a slot of the at least one slot extends across a circumferential extent of the second pad, and is configured to receive the at least one wire from a central opening of the second pad.

10. The assembly of claim 9 , wherein the at least one wire includes a solder joint.

11. A housing for a torque motor, comprising:
a shell, the shell having a first wall and a second wall defining a cavity configured to receive a torque motor; and
a first pad arranged within the shell and adjacent the first wall, and a second, complaint pad arranged adjacent the first pad, wherein the first and second pads are configured to trap at least one wire therebetween, wherein the second compliant pad is configured to be inert with respect to the at least one wire.

12. The housing of claim 11 , wherein the second complaint pad provides damping of vibratory loads.

13. The housing of claim 11 , wherein the second complaint pad is formed from a rubber sponge material.

14. The housing of claim 11 , wherein the second complaint pad is annular in shape, wherein the second pad has a central opening configured to receive the at least one wire therethrough.

15. The housing of claim 11 , wherein the second complaint pad includes at least one slot configured to receive the at least one wire.

16. A method of assembling a torque motor assembly, including:
inserting a first pad into a shell adjacent a top wall of the shell;
routing at least one wire through a central opening in a second compliant pad;
inserting the second pad into the shell adjacent the first pad such that the at least one wire is trapped between the first and second pads; and
inserting a torque motor into the shell adjacent the second pad.

17. The method of claim 16 , wherein the second pad provides is configured to damp vibratory loads.

18. The method of claim 16 , wherein the at least one wire includes a solder joint.
