A rotary dynamic sealing device for boat-carrying photoelectric equipment relates to the precision machinery technical field and aims to solve sealing difficulties of the prior-art rotary dynamic sealing devices, to further improve the shaft rotating accuracy, and to prolong the service life of the boat-carrying photoelectric equipment. The rotary dynamic sealing device comprises a rotating portion, a pedestal portion, a rotating shaft, the upper ring of a labyrinth sealing and the upper ring of the labyrinth sealing. The said device also comprises a sealing loop, an upper sealing ring, a floating sealing ring, a positioning guiding mechanism and a pedestal outer ring. The pedestal outer ring is fastened to the labyrinth upper ring which is partly connected with the rotating portion; the rotating portion is connected with the rotating shaft; the sealing loop extends into the groove of the labyrinth sealing lower ring which is fastened to the pedestal portion; and the positioning guiding mechanism is connected with the labyrinth sealing lower ring and is embedded inside the floating sealing ring which is connected with the upper sealing ring. The present invention is widely appliedin boat-carrying photoelectric equipment.
Description
technical field [0001] The invention relates to the technical field of precision machinery, in particular to a rotary dynamic sealing mechanism of a ship-borne optoelectronic device at a rotating dynamic and static joint. Background technique [0002] Since the working environment of ship-borne optoelectronic equipment is very harsh, it is often eroded by harsh environments such as wind, humidity, high temperature, mold, and salt spray. This made the environmental adaptability of the optoelectronic equipment considered at the beginning of the development. Corresponding measures have been taken to maximize the reliability and service life of the equipment. For example, in the structural design, measures such as sealing design, adding sealing strips, applying sealant, and designing labyrinth seals are usually adopted to isolate them from the harsh external conditions to ensure the three-proof performance of optoelectronic equipment. Photoelectric equipment with a precision ro...
