AI Technical Summary

Technical Problem

The outer ring structure of existing vehicle-mounted missiles cannot meet the complex arrangement requirements of component connection lines, especially in terms of the improvement of angle change control capabilities and the leverage swing of the control system.

Method used

The outer circle of the outer circle was installed by changing the Φ4 cylinder and M1.6 threaded holes used to install the bearings to the first and second bearings, which were originally used to install the bearings, and the outer circle of the second bearings were processed by the head of the M3.5×0.35. The external thread and Φ2 wire holes add wiring troughs with a depth of 0.8 on both sides to arrange the connection lines.

Benefits of technology

The stable arrangement of the connecting lines is achieved, preventing the exposed lines, ensuring sufficient space for parts when swinging, and improving the connection stability of the bearings at both ends and the satisfaction of the swing amplitude.

[0004] Technical Solution

[0005] A vehicle-mounted missile outer ring comprises an outer ring body, on which are arranged two symmetrically positioned circular rings for mounting bearings and side plates, wherein a first bearing mounting outer circle is fixedly arranged on the outer side of one of the side plates, a second bearing mounting outer circle is fixedly connected to a side of the first bearing mounting outer circle away from the outer ring body, a wiring groove is arranged in an opposite side surface of the side plate, and a wiring hole is arranged at a position of the wiring groove directly opposite to the first bearing mounting outer circle.

[0006] Furthermore, the wire hole passes through the first bearing installation outer circle and the second bearing installation outer circle.

[0007] Furthermore, a bearing mounting hole is provided on a side of the other side plate away from the outer ring body.

[0008] Furthermore, an M3.5*0.35 external thread is provided on the outer circle of the second bearing installation.

[0009] Furthermore, the outer diameter of the first bearing mounting outer circle is 5 mm.

[0010] Furthermore, the outer diameter of the second bearing mounting outer circle is 3.5 mm.

[0011] Furthermore, the inner diameter of the bearing mounting hole is 9 mm.

[0012] Furthermore, the inner diameter of the wire hole is 2 mm.

[0013] Furthermore, the depth of the wiring groove is 0.8 mm.

[0014] Beneficial Effects

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The Φ4 cylinder and the middle M1.6 threaded hole originally used for mounting the bearing were changed to Φ5 and Φ3.5 for the first bearing mounting outer circle and the second bearing mounting outer circle, and an M3.5×0.35 external thread was machined on the head of the second bearing mounting outer circle, and a Φ2 wire hole was machined in the middle. Two 0.8-deep wiring grooves were added on both sides of the inner cavity for arranging the connecting lines, so that the connecting lines are no longer exposed on the inner and outer surfaces of the outer ring parts, ensuring that there is enough space when the parts are deflected, and the connection between the bearings at both ends is more stable and reliable to meet the requirements of the swing amplitude.
