Position turning table applicable to vehicle-mounted reconnaissance system and mounting method of position turning table

Abstract

The invention discloses a position turning table applicable to a vehicle-mounted reconnaissance system and a mounting method of the position turning table. A static shaft and a moving shaft of the position turning table are connected through single direction thrust ball bearings, back-to-back angle contact ball bearings and angle contact ball bearings; hollow shafts and connecting plates are supported by the single direction thrust ball bearings, the back-to-back angle contact ball bearings and the angle contact ball bearings to form a position support platform. The position turning table is capable of achieving dynamic sealing through a magnetic fluid sealing ring, is good in sealing property and good in bearing capability, and the moment is also smaller than that of a conventional labyrinth seal mode; a photoelectric collector ring is adopted for signal conversion; large-diameter thrust bearings are adopted to bear a large load; an optical fiber sliding ring is adopted for optical fiber transmission, and a function can be achieved; due to addition of the filter in the position turning table, electromagnetic interference can be shielded.

Description

technical field [0001] The invention belongs to the technical field of photoelectric tracking, and mainly relates to an azimuth turntable, in particular to an azimuth turntable suitable for a vehicle-mounted reconnaissance system and an installation method thereof. Background technique [0002] Modern warfare is a war of informationized electronic equipment. The land vehicle photoelectric reconnaissance system is no exception, and more electronic equipment is applied to realize its functions of tracking, capturing and aiming at targets. The photoelectric turret is the carrier for integrating these electronic devices. The photoelectric turret is generally divided into two parts: the azimuth turntable and the pitch turntable. The pitch turntable is installed on the azimuth turntable. Therefore, the azimuth turntable has become a platform to carry these electronic devices and ensure their azimuth rotation. This requires the azimuth turntable to carry a large load first, so a...

Problems solved by technology

Moreover, the azimuth device disclosed in Chinese patent application 201310214843.7 does not have the functions of optical fiber transmission and anti-electromagnetic interference; its peripheral vision function adopts the mode of cable connection, so the resolution of the captured target image is also low

In the azimuth device disclosed in Chinese patent application 201310214843.7, the earliest labyrinth seal is used. This sealing form has general sealing performance, and the sealing form does not have load-bearing capacity and the torque is relatively large.
