Problems solved by technology

[0003] With the development of radar stabilized platform technology, higher technical requirements are put forward for the radar stabilized platform in terms of decoupling capability and vibration resistance. The previous indirect drive radar stabilized platform is difficult or unable to meet the new technology requirements. Adopt torque motor direct drive structure
Due to the fact that the torque motor direct drive structure has an actual motion axis, and there is a huge difference from the previous indirect drive radar stabilized platform structure, after the multi-unit radar feeder is connected to the radar antenna, it cannot be directly wired to the back end of the stabilized platform and the radar signal processing module. docking

Embodiment 1

[0023] When the torque motor 3 is used to directly drive the radar stabilization platform, the components involved in the wiring structure include the outer frame 1, the inner frame 2, the torque motor 3, the upper shaft 4, the bearing 5, the lower shaft 6, the lower shaft pressure ring 7, the bearing inner Pressure ring 8, bearing outer pressure ring 9, radar antenna 10, internal radar feeder 11 and external radar feeder 12, such as figure 1 shown;

[0024] Both the outer frame 1 and the inner frame 2 are U-shaped structures, the open end is called the front end, and the closed end is called the rear end, and through holes are respectively processed on the upper side wall and the lower side wall;

[0025] A through hole is processed on the rotor of the torque motor 3, and the end face of the through hole is processed into rounded corners;

[0026] The upper shaft 4 and the lower shaft 6 are both hollow ring structures, wherein the inner surface of the lower shaft 6 is compos...

Abstract

The invention relates to a wiring structure of a limited corner radar stabilized platform, and belongs to the technical field of a radar stabilized platform. The wiring structure is suitable for a radar stabilized platform directly driven by a torque motor, the inner and outer frames of a U-type structure are intersected to ensure that the external radar feed line is always led out of the inner frame, passes through a shaft and is extended out of the outer frame so that it is avoided that the external radar feed line repeatedly passes through the same axle hole front and back; the wiring spaceon the torque motor is fully utilized, the sizes of a rotor inner hole, an upper shaft inner hole and a lower shaft inner hole are further limited to achieve maximization of the wiring space and achieve wiring and dismounting of each radar feed line on the premise without shaft dismounting. The wiring structure is simple in design, avoids generation of large bending and deformation by the radar feed line when movement is performed, reduces the non-linear lead torque and improves the performance indexes of the control system.

Description

technical field [0001] The invention relates to a wiring structure of a radar stable platform with limited rotation angle, and belongs to the technical field of radar stable platforms. Background technique [0002] Most of the stable platforms with radar antenna as the load object adopt indirect drive structures such as gear transmission, chain transmission, belt transmission or arc transmission, and adopt the deceleration transmission design. The driving torque of the stable platform is relatively large when it moves, and the lead torque of the radar feeder The non-linear torque is smaller than the driving torque, which is easy to meet the requirements of the stable platform control system. The multi-unit radar feeder can be connected with the radar antenna and then directly routed to the back end of the stabilized platform to connect with the radar information processing module. The middle part of the multi-unit radar feeder is freely constrained, so that it does not inter...
