Embodiment 1

[0086] Such as Figure 1-1 to Figure 1-3 As shown, this embodiment provides a two-axis two-frame photoelectric stabilization platform based on wire rope transmission, which includes an azimuth assembly 1, a U-shaped frame assembly 2, and a pitch assembly 3, and has two rotation axes of azimuth and pitch, both of which use wire rope groups transmission. The overall dimensions of the platform in this example are: diameter 298mm, height 420mm, suitable for a two-axis two-frame photoelectric stabilization system of about 20kg. When designing, the number of steel wire rope groups (or even a single wire rope) can be reduced according to the actual situation, so as to meet the requirements of the photoelectric system with smaller volume and weight.

[0087] The azimuth assembly 1 includes: an azimuth transmission assembly 4 and an azimuth adapter plate 5 ; the azimuth adapter plate 5 is a disk-shaped component used to connect the azimuth assembly 1 and the U-shaped frame assembly 2 b...

Abstract

The invention belongs to the technical field of precision mechanical transmission, and particularly relates to a two-shaft two-frame photoelectric stabilization platform based on steel wire rope transmission. The platform comprises an azimuth assembly, a U-shaped frame assembly and a pitching assembly, wherein a steel wire rope is wound around a driving wheel and a driven wheel in an 8-shaped manner in the azimuth assembly and the pitching assembly, the driving wheel rotates to drive the steel wire rope to move, the steel wire rope pulls the driven wheel to rotate, and then the limited angularrotation of the azimuth and the pitching of the platform is realized. The two-shaft two-frame stabilization platform adopts a torque direct drive motor + steel wire rope transmission mode, and has the characteristics of high transmission precision and transmission rigidity, simple structure, convenient disassembly and assembly, low machining cost, and easy platform light quantization and miniaturization. The problem that the size and weight of the platform is large when a traditional two-shaft two-frame platform adopt moment direct drive, or the problem of low backlash transmission rigidity of the platform during gear reduction driving is solved.

Description

technical field [0001] The invention belongs to the technical field of precision mechanical transmission, and in particular relates to a two-axis, two-frame photoelectric stabilization platform based on wire rope transmission. The platform can meet the use requirements of miniaturization, light weight and high-performance photoelectric systems. Background technique [0002] UAVs have broad application prospects in the military and civilian fields, and are currently developing rapidly in the direction of miniaturization, light weight, and intelligence. This makes airborne optoelectronic systems face great challenges in terms of miniaturization, light weight, and performance improvement. Most of the existing small UAV-borne optoelectronic products are designed based on a two-axis two-frame stable platform, and the platform azimuth and pitch are driven by torque motor direct drive or gear reduction drive. The direct drive of the torque motor requires a large torque motor, and t...
