Embodiment Construction

[0023] Refer to the above attached picture , the specific implementation of the offset type universal ball joint for the millimeter wave seeker of the present invention is described in detail as follows.

[0024] Such as Figure 4 As shown, the offset universal ball joint for the millimeter wave seeker of the present invention consists of an inner ring 1 , an intermediate ring 2 and an outer ring 3 . where the inner ring 1 (see Figure 5 ) provides the outer spherical surface and is connected with the intermediate ring 2 (see Figure 6 ) The inner spherical surface is matched with the center of the sphere; the diameter of the spherical surface of the inner ring 1 is 60f5, and the height of the spherical surface is 4.4. Middle ring 2 (see Figure 6 ) provide the inner and outer spherical surfaces and respectively connect with the inner ring 1 (see Figure 5 ) outer spherical surface and outer ring 3 (see Figure 7 ) The inner spherical surface is matched with the center ...

Abstract

The invention discloses a polarization type universal ball hinge for a millimeter wave guide seeker, which comprises an inner ring, a middle ring and an outer ring, wherein the inner spherical surface of the middle ring is matched with the outer spherical surface of the inner ring in a gap mode; the outer spherical surface of the middle ring is matched with the inner spherical surface of the outer ring in a gap mode; the four spherical surfaces have the same spherical center which is positioned outside the entity of the middle ring; the distance between the spherical center and the end surface of the middle ring is H; the upper end mouth of the middle ring is a cylindrical surface and is used for connecting an antenna bracket or directly connecting the antenna bracket with an antenna; theaxial of the cylindrical surface passes through the spherical center; the pitching and the swing of the antenna are realized through the movement of the middle ring between the spherical surfaces of the inner ring and the outer ring; and the bottom of the outer ring and the main body of the seeker are connected, supports and fixes the inner ring. The polarization type universal ball hinge has theadvantages that the 3mm seeker meets the requirement that the rotating center of the antenna is positioned in the center of the upper surface of the antenna; the antenna is positioned in the most reasonable space position for the 8mm seeker; the effective area of the antenna can be obviously enlarged for the missiles with the same caliber; and the radar property of the seeker is enhanced.

Description

technical field [0001] The invention belongs to a mechanical transmission device, in particular to an offset type universal ball hinge for a millimeter-wave seeker, which is used to realize the support, pitch, and azimuth limited-angle movements of the seeker antenna. technical background [0002] With the development of millimeter-wave seeker technology, different requirements are put forward for the antenna support and two-dimensional motion support drive mechanism in azimuth and pitch. For the 3mm seeker, the antenna is required to be able to complete the azimuth and pitch two-dimensional limited angular motion around the center of the antenna front; the antenna with no special requirements for the antenna rotation center (such as the 8mm seeker) should be located in the most reasonable spatial position (antenna does not touch the inner wall of the missile when rotating), thus significantly increasing the [0003] Antenna area, improving the overall performance of the se...
