Description

Technical Field

[0001] The utility model relates to the technical field of the design and manufacture of seekers for guided weapon systems, and particularly relates to a seeker for a guided weapon system and a compact motor drive mechanism thereof. Background Art

[0002] A seeker is a key component in a guided weapon system such as a missile, usually installed at the head of the weapon, used for automatically searching, tracking a target, and measuring the position and motion parameters of the target, providing target information for the guidance system of the weapon, and guiding the weapon to fly accurately towards the target. Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the seeker includes a main frame 10, a head cover 1 covering the main frame 10, an outer frame sensor 17, an outer frame motor 15, and an inner frame 3 installed on the main frame 10, an optoelectronic load 2 and an inner frame sensor 16 installed on the inner frame 3, an inner frame motor 14 (including a motor stator 4, a motor rotor 5, a fixing nut 6, a motor rotating shaft 7, a motor retaining ring 8, a bearing 9), and an inner frame sensor rotating shaft 18 for connecting the inner frame sensor 16 and the optoelectronic load 2, and an inner frame motor rotating shaft 7 for connecting the inner frame motor 14 and the optoelectronic load 2. The inner frame motor 14 drives the optoelectronic load 2 to perform a rotational movement in a first rotational direction A; the outer frame motor 15 drives the inner frame 3 and the components installed on the inner frame 3 (the inner frame motor 14, the inner frame sensor 16, the optoelectronic load 2) to perform a rotational movement in a second rotational direction B perpendicular to the first rotational direction A.

[0003] As can be seen from the figure, the existing seeker adopts a direct drive motor drive mechanism. In the axial direction of the motor, a bearing and an electromagnetic component (i.e., the motor rotor and the motor stator) are arranged in series, which has the problem of large occupied space. Specifically, when the outer frame motor 15 drives the entire inner frame (i.e., the inner frame 3 and the inner frame motor 14, the inner frame sensor 16, the optoelectronic load 2 installed on the inner frame 3) to perform a rotational movement in the second rotational direction B, the installation position of the inner frame motor 14 will interfere with the head cover 1 of the seeker, affecting the rotational angle of the optoelectronic load 2 in the second rotational direction B (i.e., affecting the frame angle of the seeker). In addition, the space for the motor position in the seeker is cramped, and the size of the motor is limited, which will lead to limited driving ability of the seeker. Therefore, there is an urgent need for a compact direct drive motor drive mechanism that makes the installation position of the motor occupy less axial space. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a seeker for a guided weapon system and a compact motor drive mechanism thereof to reduce the axial occupied space of the motor.

[0005] A compact motor drive mechanism for a seeker of a guided weapon system provided by the present utility model includes: a motor stator and a motor rotor, which are installed in a motor mounting seat provided on one side of the inner frame of the seeker; a bearing, which is installed in a bearing mounting seat provided on the other side of the inner frame and is radially coplanar with the motor stator and the motor rotor, forming a coplanar support structure of the bearing, the motor stator, and the motor rotor; a motor shaft, which is inserted into the inner ring of the bearing and is sleeved with the mounting hole of the motor rotor; wherein, the end face of the mounting hole of the motor rotor sleeving the motor shaft contacts the inner ring of the bearing.

[0006] Preferably, one side and the other side of the inner frame respectively correspond to the input side and the output side of the motor drive mechanism.

[0007] Preferably, the mechanism further includes: an L-shaped bearing gland for fixing the bearing on the output side of the motor drive mechanism, the first side of which is fixed to the inner frame by screws, and the end of the second side contacts the outer ring of the bearing.

[0008] Preferably, the mechanism further includes: screws for fixedly connecting the motor rotor and the motor shaft on the input side of the motor drive mechanism.

[0009] Preferably, the mechanism further includes a fixing nut, which is screwed onto the threaded end of the motor shaft on the input side of the motor drive mechanism and presses the end face thereof against the motor rotor.

[0010] Preferably, one side and the other side of the inner frame respectively correspond to the output side and the input side of the motor drive mechanism.

[0011] Preferably, the mechanism further includes: an L-shaped bearing gland for fixing the bearing on the input side of the motor drive mechanism, the first side of which is fixed to the inner frame by screws, and the end of the second side contacts the outer ring of the bearing.

[0012] Preferably, the mechanism further includes: a bearing inner ring pressing plate for fixing the bearing; screws for fixing the bearing inner ring pressing plate on the motor shaft on the input side of the motor drive mechanism.

[0013] Preferably, the mechanism further includes a fixing nut, which is screwed onto the threaded end of the motor shaft on the input side of the motor drive mechanism and makes its end face contact the inner ring of the bearing.

[0014] The present utility model also provides a seeker for a guided weapon system, including an inner frame and the compact motor drive mechanism of the seeker as described above, which is installed on the inner frame.

[0015] The bearing, motor stator, and motor rotor of the present utility model are coplanar in the radial direction of the motor, forming a coplanar support structure, which can reduce the axial occupied space of the inner-frame motor position. In this way, the inner-frame motor position can be closer to the rotation center of the inner frame, and the space between the inner-frame motor and the head cover is larger, which can increase the frame angle of the seeker. Secondly, the thickness of the electromagnetic components (i.e., motor stator + motor rotor) of the inner-frame motor can be increased to drive a larger optoelectronic load. In addition, a larger space can be provided for the optoelectronic load to support the seeker of the guided weapon system to adopt a larger optoelectronic load. Description of the Drawings
