Description
Technical field
The utility model is related to actuator sealing structure technical field, the star-like circle group of specially a kind of actuator dynamic sealing
Part.
Background technology
Sealing in machine between relative motion part.Dynamic sealing is divided into two class of reciprocating dynamic sealing and rotary dynamic sealing.
Reciprocating dynamic sealing has shaped packing seal, packing box seal and expansion ring seale.Rotary dynamic sealing has：Movement parts and static element
The contact dynamic sealing being in direct contact；The contactless dynamic sealing that the two is not directly contacted with；It is flowed in seal clearance using addition
The special nature of body reaches the semifluid dynamic sealing of sealing.Semifluid dynamic sealing has magnet fluid sealing.Some machine and equipments must
It must be absolutely sealed, some permissions leak on a small quantity, so should be according to behaviour such as the property of working media, temperature, pressure and relative velocities
Make the structural shape that condition and the requirement to sealing performance etc. are selected or design seals, however existing actuator dynamic sealing is close
Envelope effect is poor, and leak source is more, and voltage endurance capability is low, and service life is short.
Utility model content
The purpose of this utility model is to provide a kind of star-like coil assemblies of actuator dynamic sealing, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the utility model provides the following technical solutions：A kind of star-like circle group of actuator dynamic sealing
Part, including cylinder body, the cylinder body left side wall are fixedly connected with end cap by clamping screw, and the cylinder body right side wall connects cylinder cap,
The inner chamber of cylinder block is connected with piston rod, and the push rod through cylinder cap, institute are fixedly connected in the middle part of the piston rod right side wall
It states push rod and is equipped with star-like sealing ring between outer wall and the contact surface of cylinder cap up and down.
Preferably, the cylinder cap is equipped with the through-hole to match with push rod.
Preferably, the junction of inner wall and piston rod is equipped with gasket to the cylinder body up and down.
Preferably, the end of the push rod is equipped with multi-diameter shaft, and one end of multi-diameter shaft is additionally provided with arc angling.
Compared with prior art, the utility model has the beneficial effects that：The star-like coil assembly of this actuator dynamic sealing executes
The dynamic sealing of device using star-like sealing ring replace traditional O-ring, optimize sealing structure, reduce leak source, realize two-point bidirectional by
Means of press seals, lift-off seal effect improve service life.Actuator entirety voltage endurance capability improves, and improves product service efficiency.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of star-like coil assembly of actuator dynamic sealing,
Including cylinder body 1,1 left side wall of the cylinder body is fixedly connected with end cap 2 by clamping screw 6, and 1 right side wall of the cylinder body connects cylinder cap
3,1 inner cavity of the cylinder body is connected with piston rod 5, and pushing away through cylinder cap 3 is fixedly connected in the middle part of 5 right side wall of the piston rod
Bar 4, is equipped with star-like sealing ring 7 between about 4 outer wall of the push rod and the contact surface of cylinder cap 3, the cylinder cap 3 is equipped with and push rod 4
The junction of the through-hole 8 to match, about 1 inner wall of the cylinder body and piston rod 5 is equipped with gasket 9, and the end of the push rod 4 is set
There is multi-diameter shaft, and one end of multi-diameter shaft is additionally provided with arc angling.
Operation principle：When specifically used, the dynamic sealing of actuator replaces traditional O-ring, optimization using star-like sealing ring 7
Sealing structure reduces leak source, realizes that two-point bidirectional compression seal, the setting of clamping screw 6 are used for fixing end cap 2 and cylinder cap 3, make
3 convenient disassembly of end cap 2 and cylinder cap is obtained, convenient for being overhauled to the piston rod 5 in cylinder body.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
