Abstract
The present invention relates to a kind of sealing rings, and including waterproof baffle ring, the waterproof baffle ring is equipped with through the waterproof baffle ring and the through hole for being inserted into rotation axis, and the through hole axially sets protrusions more than twice or twice along it, and the height of adjacent protrusion differs.The sealing ring further includes the waterproof protrusion radially extended along waterproof baffle ring one end peripheral surface towards the waterproof baffle ring.Beneficial effects of the present invention：By the way that the through hole axially to be set to protrusions more than twice or twice along it, the height of adjacent protrusion differs, so that through hole is in close contact with rotation axis, reduces the friction between the sealing ring and the rotation axis, in favor of the rotation of the rotation axis.
Description
Technical field
The present invention relates to a kind of sealing rings.
Background technology
In recent years, as multi-rotor aerocraft develops, because its with maneuverability, rapid reaction, unmanned flight, operation will
Low advantage is sought, its application in multiple fields is caused, particularly in agricultural plant protection field.Sprinkling on multi-rotor aerocraft
Device is one of pith for influencing its operating efficiency.
In the relevant technologies, there are sealing problem between the drive shaft of flusher and installation housing, liquid be easy into
Enter actuator short circuit and the corrosion to installation enclosure interior, caused in flusher, significantly reduce the reliable of flusher
Property and service life.Conventional sealing ring is not sufficient to play the role of being fully sealed, such as O-ring seal, but also can shadow
Ring the rotational efficienty to rotating member (such as drive shaft).
Invention content
The present invention provides a kind of sealing ring, it is intended to the technical issues of solving in the relevant technologies at least to a certain extent it
One.
A kind of sealing ring according to embodiments of the present invention, including waterproof baffle ring, the waterproof baffle ring is equipped with through described anti-
Water baffle ring and the through hole for being inserted into rotation axis, the through hole axially set protrusions more than twice or twice, phase along it
The height of adjacent protrusion differs.
In some preferred embodiments, the sealing ring is further included to be prevented along waterproof baffle ring one end peripheral surface towards described
The waterproof protrusion that water baffle ring radially extends.
Beneficial effects of the present invention：It is adjacent by the way that through hole axially to be set to protrusions more than twice or twice along it
The height of protrusion differs, so that through hole is in close contact with rotation axis, reduces between the sealing ring and the rotation axis
Friction, in favor of the rotation of the rotation axis.
Description of the drawings
Fig. 1 is the structure diagram of sealing ring according to embodiments of the present invention.
Specific embodiment
The embodiment of the present invention is described below in detail, the example of the embodiment is shown in the drawings.Below with reference to
The embodiment of attached drawing description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
Shown in Figure 1, a kind of sealing ring of the embodiment of the present invention, including waterproof baffle ring 1, the waterproof baffle ring 1 is set
Have through the waterproof baffle ring 1 and the through hole 2 for being inserted into rotation axis, the through hole 2 axially set twice or two along it
Protrusion 4 more than road, the height of adjacent protrusion 4 differ.
In some preferred embodiments, the sealing ring is further included along 1 one end peripheral surface of waterproof baffle ring towards described
The waterproof protrusion 3 that waterproof baffle ring 1 radially extends.
Beneficial effects of the present invention：It is adjacent by the way that through hole 2 axially to be set to protrusions 4 more than twice or twice along it
The height of protrusion 4 differ so that through hole 2 is in close contact with rotation axis, reduce the sealing ring and the rotation axis it
Between friction, in favor of the rotation of the rotation axis.The sealing ring is arranged concentrically the waterproof protrusion 3 with convex using the waterproof
Serve 3 play it is radial and axial fixed.
Claims (2)
