Description
Technical field
The utility model relates to a kind of seal arrangement, in particular for the high pressure resistant seal structural part of hydraulic pressure, air pressure facility, belongs to hydraulic pressure, pneumatic seal technical field.
Background technique
The sealing of O RunddichtringO is the Sealing of using always, this type of Sealing is generally used for hydraulic pressure, pneumatic actuator mesopore or plane sealing, its basic project organization can find on corresponding sealing technique handbook, usually be installed in the ring shaped slot of cylinder or conical surface, wherein the groove dimensions of rectangular configuration is bigger by about 15% than the volume of O type circle.
Understand according to the claimant, in the product of cycloid hydraulic motor and so on, the junction plane of adjacent entities member all adopts the integral planar sealing, and the location then mainly guarantees by the gap in connecting bolt hole.Wherein, the integrated support structure such as body shell (having the connecting plate purposes concurrently) is unfavorable for improving wear resistance and intensity.And for the ease of assembling, bolt hole must have enough gaps by stream, and the result often connects unbalance loading because of locating the inaccurate spline of output shaft that causes.
The model utility content
The purpose of this utility model is: by the research to O RunddichtringO sealing mechanism, it is easy, reliable and be convenient to the characteristics of demolition and maintenance to make full use of O RunddichtringO sealing, a kind of O RunddichtringO seal arrangement simple in structure, practicable is proposed, this device should be able to be properly settled the problem of accurate location under the prerequisite that guarantees reliable sealing.
When being applied to the transmission device of oil hydraulic motor and so on, should have desirable wear resistance and intensity with the junction plane that changes stator, and can guarantee the coaxality of part that respectively is connected, thereby improve the quality of product, the one-way valve cavity volume pressure-bearing that body shell and bonnet are formed.
The utility model is at the foregoing invention purpose, its technological scheme is: O RunddichtringO location seal arrangement comprises entity counterbore member, is installed in the cylinder link that matches with it in the entity counterbore member, and the stator component contiguous with counterbore member end face, the end that described stator component is adjacent with the cylinder link is shaped on the step axle that is inserted in the counterbore, fit in the termination of the end face of described step axle and cylinder link, the applying end cylindrical of one of described cylinder link and stator component is shaped on the step annular groove of setting-in O RunddichtringO.
After the assembling, the O RunddichtringO is positioned at entity counterbore member, cylinder connects and the junction of stator component, fit with above-mentioned three members simultaneously, play desirable seal action, simultaneously, because the step axle of cylinder link, stator component all assembles with the counterbore Spielpassung, so easy to assembly, accurate positioning helps to guarantee coaxality between the link.Calculating and experiment show, after the assembling, are advisable about the big 5-8% of volume of rectangle groove size than O type circle that the O RunddichtringO is installed.In addition, cause the circle of cutting of O RunddichtringO in order to prevent the high compression amount, can so both help guaranteeing enough compression seal effects, can avoid assembling back O RunddichtringO again and be cut circle, improve durability in the outward edge chamfering of step annular groove.
Facts have proved, when the utility model is applied to the transmission device of oil hydraulic motor and so on, can make the junction plane that changes stator have desirable wear resistance and intensity, and the coaxality of the part of being convenient to guarantee respectively to be connected, and technology difficulty reduces, practical, using effect and the life-span thereof that can improve high pressure shaft seal, and the working efficiency of one-way valve.

Embodiment
Embodiment one
The O RunddichtringO location seal arrangement of present embodiment is applied in the oil hydraulic motor, and as shown in Figure 1, its applied cycloid hydraulic motor is formed the hydraulic oil reservoir body by output shaft 1, body shell 4, stator 12 and bonnet 19.Body shell 4 is monolithic constructions, and output shaft 1 is supported in the body shell by two tapered roller bearings, and high pressure shaft seal seals output shaft and body shell, and couple axle transmits mechanical energy to output shaft, thereby forms power take-off; Rotor 30, stator 12 and pin tooth 29 form energy conversion device; Flow platen 14, thrust plate 15, flow dunnage 20 and bonnet 19 have been formed a flow-distribution mechanism.Two check valve body structures are arranged in the reservoir body, by steel ball 27, support 26 and plug screw assembly 25 constitute, under positive and negative two the sense of rotation working staties of motor, two check valve body are alternately in running order, internal drainage liquid forms the loop in cavity, lubricated, cooling bearing 5, and turn back to hydraulic circuit.The passage that different height pressure oil is arranged between each entity, each joint have different oil pressure gap and sealing configuration thereof.
Wherein two O RunddichtringOs 11 are installed in respectively in three of the two places junction planes that connect entities, are respectively body shell 4, connecting plate 10 and stator 12, and stator 12, flow platen 14 and bonnet 19.
Its concrete structure as shown in Figure 2, the entity component that right-hand member is shaped on counterbore is a body shell 4, and the cylinder link that cylindrical and counterbore match--connecting plate 10 wherein is installed, body shell 4 end face adjacent stator 12 constitute and to compress supporting plane.This stator 12 and connecting plate 10 adjacent ends are shaped on the step axle that is inserted in the counterbore, fit in the termination of the end face of this step axle and connecting plate 10, the applying end cylindrical of connecting plate is shaped on the step annular groove of setting-in O RunddichtringO 11, and this annular groove outer end edges is shaped on chamfering, be convenient to setting-in O RunddichtringO 11 like this, and avoid cutting the circle phenomenon.The step annular groove is designed to pack into behind the O RunddichtringO, about the volume big 5-8% of size than O type circle of the rectangle groove that the O RunddichtringO is installed.The entity component that left end is shaped on counterbore is a bonnet 19, and the cylinder link that cylindrical and counterbore match---flow platen 14 wherein is housed, and its sealing position structure and the other end are similar, can analogize.
