Problems solved by technology

And this puts forward very high requirements for the metal surface processing technology, and even the existing technology level cannot meet the requirements.
For the labyrinth seal, it can only be dustproof, dustproof, and rainproof in general, and cannot meet the airtight requirements of Zhoushi Optoelectronics observation and sighting equipment.
The magnetic fluid seal has high requirements on the eccentricity of the shaft and is easily affected by low temperature conditions.

Embodiment Construction

[0021] The embodiments and accompanying drawings are given below, and the specific implementation and process of the technical solution of the present invention are described in detail. However, the protection scope of the claims of the present application is not limited to the description of the following embodiments.

[0022] The composite rotary dynamic sealing structure (referred to as the sealing structure) of the present invention includes a fixed body 1, a rotating body 2, a gasket 3, a first pressure sealing ring 4, a U-shaped sealing ring 5, an O-shaped sealing ring 6, a second Pressure seal ring 7, labyrinth seal 8. Between the fixed body and the rotating body, the end face dynamic seal, the radial dynamic seal and the labyrinth seal are used sequentially from the inside to the outside in the radial direction.

[0023] The dynamic sealing of the end face is realized by the gasket 3, the first pressure sealing ring 4 and the U-shaped sealing ring 5; there is an annul...

Abstract

The invention discloses a compound rotating dynamic seal structure of a panoramic photoelectric observing device, and belongs to the field of mechanical seal. The rotating dynamic seal structure mainly comprises a fixed body, a rotating body and a seal structure unit, wherein end face dynamic seal, radial dynamic seal and labyrinth seal are sequentially and radially adopted between the fixed bodyand the rotating body from interior to exterior; end face dynamic seal is achieved through a gasket 3, a first pressure seal ring 4 and a U-shaped seal ring 5; after the fixed body and the rotating body are in contact, the U-shaped seal ring 5 is tightly pressed through the gasket 3 and the first pressure seal ring 4, and end face dynamic seal is achieved; radial dynamic seal and labyrinth seal are achieved through continuous annular clearances in the fixed body and the rotating body; and the annular clearances are filled with felt oil rings, and the protective effect of labyrinth seal 8 for rainwater and dust is strengthened. End face dynamic seal, radial dynamic seal and labyrinth seal are matched, and the sealing structure is good in sealing effect, high in reliability, long in servicelife and simple in processing.

Description

technical field [0001] The invention belongs to the dynamic sealing technology in the mechanical field, in particular to a composite rotary dynamic sealing structure, which is used to realize a high reliability and long service life rotary dynamic seal. Background technique [0002] Rotary dynamic seals are commonly used in electromechanical equipment such as Zhoushi photoelectric observation and sighting equipment. The sealing effect directly affects the overall performance of the equipment, and it is a key issue that needs to be paid attention to and solved in the electromechanical design process. [0003] There are two main types of rotary dynamic seals commonly used in engineering: one is contact seals, which are sealed by extrusion seals and formed seals (composed of lip seals such as U-shaped seals and extruded seals such as O-rings) The second type is a non-contact sealing form, such as a magnetic fluid seal and a labyrinth seal. For example, in the patent document "...
