Description
Technical field
The utility model is related to hydraulic motor plunger technical field, more particularly to a kind of injecting glue post for hydraulic motor
Plug structure.
Background technology
Current hydraulic motor industry is generally applied in hydraulic motor using solid metal plunger.Solid metal plunger makes
Requirement is disclosure satisfy that in, but increases the inertia force in plunger work, the rotary inertia of hydraulic motor is added.Use hydraulic pressure
Time of the motor in braking procedure increased, and reduce hydraulic system uses rigidity, in order to solve this problem, design
A kind of injecting glue plunger is necessary.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of injecting glue piston structure for hydraulic motor, effectively
The quality of duty plunger is reduced, the inertia force of plunger in hydraulic motor running is reduced, turning for hydraulic motor is reduced
Dynamic inertia, the colloid that injecting glue plunger is injected is filled with the aperture segment of metal plunger, while plunger quality is reduced, does not increase
Trapped fuel amount in strutting plug, is not changed using the The hydraulic oil in plunger case.The application of injecting glue plunger does not influence hydraulic pressure
The use rigidity of motor in systems.
The utility model solves the technical scheme that its technical problem used：A kind of injecting glue for hydraulic motor is provided
Plunger cavity, plunger cavity are disposed with piston structure, including rotor body, roller and injecting glue plunger, described rotor body vertically
Lower end is disposed with the oil inlet of side and oil communication, and described injecting glue plunger is inserted vertically into plunger cavity top, institute
The injecting glue plunger stated includes being disposed with injecting glue body, described injecting glue post on metal body and injecting glue body, metal body lower end
End is provided with roller beyond the Great Wall, and described roller upper end is arranged on curvilinear guide.
Described metal body lower end, which is disposed with some hole positions, hole position, is filled with injecting glue body.
Insertion is provided with sealing ring on described injecting glue plunger outer ring, for sealed plunger chamber.
Beneficial effect：The utility model is related to a kind of injecting glue piston structure for hydraulic motor, effectively reduces work
The quality of plunger, reduces the inertia force of plunger in hydraulic motor running, reduces the rotary inertia of hydraulic motor, injecting glue
The colloid that plunger is injected is filled with the aperture segment of metal plunger, while plunger quality is reduced, does not increase in plunger
Trapped fuel amount, is not changed using the The hydraulic oil in plunger case.The application of injecting glue plunger does not influence hydraulic motor in system
In using rigidity.

Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation scope of the present utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
Embodiment of the present utility model is related to a kind of injecting glue piston structure for hydraulic motor, as shown in Fig. 1-3,
Including rotor body 4, roller 2 and injecting glue plunger 3, plunger cavity, plunger cavity lower end cloth are disposed with vertically on described rotor body 4
The oil inlet of side and oil communication is equipped with, described injecting glue plunger 3 is inserted vertically into plunger cavity top, described note
Glue plunger 3 includes being disposed with injecting glue body 6, described injecting glue plunger on metal body 5 and injecting glue body 6, the lower end of metal body 5
3 upper ends are provided with roller 2, and the described upper end of roller 2 is arranged on curvilinear guide 1.
The described lower end of metal body 5, which is disposed with some hole positions, hole position, is filled with injecting glue body 6.
Insertion is provided with sealing ring on the described outer ring of injecting glue plunger 3, for sealed plunger chamber.
Embodiment
Injecting glue plunger 3 is at 1 higher-pressure region of curvilinear guide, and rotor body 4 is because connect hydraulic oil, in hydraulic oil in plunger cavity
Effect is lower to promote injecting glue plunger 3 to stretch out rotor plunger cavity, roller 2 is close to curvilinear guide 1, and the decline of extension curve guide rail 1 is prolonged
Side scrolls up.Injecting glue plunger 3 connects low pressure oil return in 1 low-pressure area of curvilinear guide in the plunger cavity of rotor body 4, due to low
Nip pressure is less than higher-pressure region, and roller is in 1 rising edge of curvilinear guide by thrust, and roller 2 promotes injecting glue plunger withdrawal rotor
In plunger cavity.
The plunger of script is all fabricated by using metal parts, and the rotary inertia formed when motion is larger, and works as
When plunger makes injecting glue 3 structure of plunger into, the Quality Down of injecting glue plunger 3, center when it is rotated shifts, in reduction
While plunger quality, do not increase the trapped fuel amount in plunger, do not changed, improved using the The hydraulic oil in plunger case
The service life of hydraulic motor.
