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 specifically relates to a two-axis, two-frame photoelectric stabilization platform based on wire rope transmission. The platform includes: an azimuth component, a U-shaped frame component, and a pitch component; The steel wire ropes are wound on the driving wheel and the driven wheel in the shape of "8". The two-axis two-frame stable platform adopts the mode of torque direct drive motor + wire rope transmission, which has the characteristics of high transmission accuracy and transmission rigidity, simple structure, convenient disassembly and assembly, low processing cost, and easy platform lightweight and miniaturization. It can solve the problem of large volume and weight of the platform when the traditional two-axis and two-frame drive is directly driven by torque, or the problem of low stiffness of the empty return transmission of the platform when the gear reduction is used for drive.

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...
