Description
Technical Field
The utility model belongs to a hydraulic element in the mechanical industry, and particularly relates to an embedded high-pressure sealing piece structure.
Background
In the current oil pump and hydraulic system, most end face seal structure, because the reason of dimensional tolerance cooperation often can form great gap, and rubber belongs to elastic material, intensity is weaker, even improve the hardness of rubber, also make rubber seal extrude from the gap of both ends face easily under high pressure operating mode, influence life, traditional solution is O type circle vulcanization stereoplasm retaining ring makes it become integrative, the part precision is poor, the cost is improved, and the material is restricted, the outer stereoplasm retaining ring that increases of O type circle, be difficult for the installation, the condition of neglected loading appears easily, influence part quality.
Disclosure of Invention
The utility model aims to overcome the defects of the technology and provide the embedded high-pressure sealing element structure which has the advantages of compact structure, simple manufacturing process and good sealing effect.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides an inlay type high-pressure sealing member structure, including the pump body, the apron, the pressure board, the axle, the stator, the rotor, its characteristics are, in the peripheral pressure board of axle and apron junction and the peripheral pressure board of high-pressure medium and apron junction's high-pressure medium chamber, all be equipped with sealing member assembly groove, insert the rubber seal who takes the retaining ring to insert the groove in sealing member assembly groove, insert the stereoplasm retaining ring in retaining ring insert groove, the plane end of stereoplasm retaining ring and the inner terminal surface close fit of a plane end and the apron of rubber seal, be equipped with clearance L between the pressure board and the apron of rubber seal and stereoplasm retaining ring non-contact surface.
The beneficial effects of the utility model are as follows: the embedded high-pressure sealing member structure is a special-shaped sealing structure and is suitable for sealing various high-pressure hydraulic pumps. The design of the hard retainer ring and the rubber sealing element monomer adopts an embedded mode to seal the high-pressure oil way, has good sealing effect, effectively avoids the sealing failure caused by extrusion of the rubber sealing element from the gap of the end face, avoids the quality problem caused by position deviation generated by fixation before vulcanization, saves the vulcanization cost, ensures that the production process is simple and easy to implement, and is suitable for various high-pressure oil pumps.

The following is a detailed description of embodiments with reference to the accompanying drawings.
Fig. 1 is a front cross-sectional view of a mosaic high pressure seal structure.
Fig. 2 is an enlarged structural view of the point I in fig. 1.
In the figure, 1-cover plate; 2-a pressure plate; 2-1-a seal assembly groove; 3-a pump body; 4-high pressure medium; 5-a hard retainer ring; 6-rubber seals; 6-1-inserting grooves into the retainer rings; 7-a stator; 8-a rotor; 9-axis; l-gap.
Description of the embodiments
In the embodiment, referring to fig. 1 and 2, the embedded high-pressure sealing structure is that a shaft 9 is arranged in the middle of the pump body 3, a rotor 8 is arranged at the periphery of the shaft 9, and a stator 7 is arranged at the periphery of the rotor 8. The periphery of the left end of the shaft 9 and the left end surfaces of the rotor 8 and the stator 7 are provided with pressure plates 2, and the joint of the pressure plates 2 and the rotor 8 is provided with oil channels. The periphery of the pump body 3 is fixedly connected with a cover plate 1, a groove connected with a pressure plate 2 is arranged in the cover plate 1, and a ring-shaped high-pressure medium 4 is arranged in the cover plate 1. Two sealing element assembling grooves 2-1 are arranged at the periphery of the inner ring at the joint of the high-pressure medium 4 and the pressure plate 2. A rectangular rubber sealing piece 6 is embedded in a sealing piece assembly groove 2-1, a special-shaped retainer ring embedded groove 6-1 is formed in the rubber sealing piece 6, a special-shaped hard retainer ring 5 is embedded in the retainer ring embedded groove 6-1, and the hard retainer ring 5 can be made of metal, nylon or hard plastic. One plane end of the rubber sealing piece 6 and the hard retainer ring 5 are flush with the inner end surface of the cover plate 1, the hard retainer ring is flush with the other plane and one surface of the rubber sealing piece 6, a gap L is formed between the cover plate 1 and the pressure plate 2, and the width of the gap L is set so as not to enable the hard retainer ring 5 to be extruded.
The working principle of the utility model is as follows: the embedded high-pressure sealing structure is characterized in that the special-shaped hard retainer ring 5 is embedded into the retainer ring embedded groove 6-1 in the rubber sealing member 6 to form an integral sealing member, the hard retainer ring 5 in the sealing member is positioned on the back of the pressed surface to support the whole sealing member, the rubber sealing member 6 is prevented from being extruded from the gap L at the gap L formed by the cover plate 1 and the pressure plate 2, the rubber sealing member 6 is prevented from being damaged, and the sealing effect is ensured.
