According to the applicant understood, existing a large amount of plane flow motor adopts flow dunnage to be embedded in bonnet, apply the dual face seals that single O type circle carries out two Vertical direction, O RunddichtringO location sealing device as described in file CN2911341Y file obtains very successful effectiveness in the application, but it is high to the quality requirement of O RunddichtringO own, especially apply operating mode very mal-condition time, as temperature is high, rotating speed is high, back pressure is high, small part still likely property can there is junction plane and have oil stain phenomenon, but do not form oil dripping phenomenon, though do not affect use, but affect outward appearance.
Summary of the invention
The purpose of this utility model is: the deficiency existed for above prior art, by the research to existing O RunddichtringO location sealing device integral structure layout, the compactedness maintaining existing structure is constant, change original single O RunddichtringO simultaneously to the scheme of the dual face seals of two Vertical direction (axis and radial seal), increase the reliability of sealing, properly settle the oil stain phenomenon caused due to single O type circle dual face seals simultaneously.
In order to achieve the above object, claimant is by the structural analysis to the O RunddichtringO location sealing device technique of existing flat porting cycloid hydraulic pressure motor, finding out existing structure may cause motor junction plane to occur the reason of oil stain phenomenon, keeping under original flat porting cycloid hydraulic pressure motor structure and the constant prerequisite of boundary dimension, the technical solution of the utility model is proposed: a kind of high pressure seal structure cycloid hydraulic motor comprises entity counterbore component, be arranged on the cylindrical connection matched with it in entity counterbore component, and the stator component contiguous with counterbore component end face, one end that described stator component is adjacent with cylindrical connection is shaped with the Step Shaft be inserted in counterbore, fit in the end face of described Step Shaft and the termination of cylindrical connection, the laminating end cylindrical of one of described cylindrical connection and stator component is shaped with the step annular groove of setting-in O RunddichtringO, its improvements are: the circle of described cylindrical connection matches on face and arranges two O type circle sealing configuration, two O type circles carry out the dual face seals of two Vertical direction, described two O type circle sealing configurations are that the circle of cylindrical connection matches on face and increases an axial seal structure, independent to axially sealing further.
Described axial seal structure is sealed entity counterbore by the annular groove of the periphery of cylindrical connection and setting-in O RunddichtringO.
Further improvement, the two ends of described cylindrical connection all have two O type circle sealing configuration.
Facts have proved, after being applied by the utility model, completely avoid the original technology of O RunddichtringO location sealing device and may occur oil stain phenomenon, the improvement of structure maintains the compactedness of original structure, obtains beyond thought effect.
