Problems solved by technology

However, this device consists of a plurality of bearings to form a rotary shafting system. The outer support bearing is located at the upper end of the electromechanical components (torque motor and resolver). The independent configuration of the rotary shafting system is also not realized, and there is a problem that the bearing must be disassembled for maintenance of electromechanical components. ; In addition, the angular contact ball bearings, deep groove ball bearings, torque motors, resolvers and other electromechanical components in the device are installed on the inner and outer walls of the azimuth shaft, so that the selection of bearings and electromechanical components are related to each other, that is, the more the load of the azimuth device Larger, the larger the size of the angular contact ball bearing, the larger the size of the electromechanical components, resulting in a larger volume of the entire device

Abstract

The invention discloses an azimuth device applicable to a vehicular photoelectric turntable. The azimuth device comprises a revolving shaft system, an azimuth shell, a rotary transformer and a torque motor. The revolving shaft system comprises an azimuth dead shaft, an azimuth moving shaft, an azimuth rotating adaptor disc and two groups of bearings, the azimuth dead shaft is connected with the azimuth moving shaft and the azimuth rotating adaptor disc respectively via a first bearing and a second bearing, the first bearing bears biaxial loads, the second bearing is larger in diameter and bears radial and tipping loads, and thereby the rotating disc type revolving shaft system borne by the internal and external bearings is formed. The revolving shaft system as well as the rotary transformer and the torque motor are respectively positioned on an upper side and a lower side of an annular transverse plate in the middle of the azimuth shell and are independent to one another. Furthermore, a comprehensive labyrinth felt collar sealing structure is adopted. The azimuth device has the advantages of simple structure, low height, light weight, good maintainability, excellent expansibility, strong environmental suitability and the like, mechanical characteristics and capabilities of resisting shock, vibration and large-angle inclination of the photoelectric turntable are effectively improved, and tracking precision of photoelectric tracking equipment is guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of photoelectric tracking, and mainly relates to a photoelectric turntable, in particular to an orientation device suitable for a vehicle-mounted photoelectric turntable. Background technique [0002] As a battlefield information perception and fire control system, photoelectric tracking equipment has been used more and more widely due to its unique characteristics. The photoelectric turntable is the core component of the photoelectric tracking equipment. Its basic structure is a set of two-axis precision servo turntable, which is used to carry photoelectric sensors such as TV cameras, infrared thermal imaging cameras and laser rangefinders to realize the orientation and elevation of the photoelectric tracking equipment. The direction of the target detection, capture and tracking. Most photoelectric turntables adopt the ground-level structure mode, that is, the pitch-azimuth (E-A) mode, in which the azimuth devi...
