The structural characteristics is that a surface, wherein the seal ring and the sphere are in contact with each other, is a spherical surface and the diameter of the spherical surface is equal to the diameter of the sphere. The globe joint has better sealing effect, non-easy abrasion, and longer performance life. The globe joint is suitable for being utilized in the semi-immersed oar propulsion means of watercraft.
Description
(1) technical field
The utility model relates to a kind of turning joint.Be ball and socket specifically, be applicable to partly soaking in the oar propulsive unit of boats and ships with double seal function.
(2) background technology
At present, partly soaking in the oar propulsive unit of boats and ships, used ball and socket all is made up of ball seat, spheroid and connecting rod.Ball seat wherein is a sleeve shaped, and the one end has radially outer lug boss, and its medial surface is a sphere.Said spheroid places in the ball seat, and its diameter adapts with the diameter of ball seat medial surface and the two is moving type and cooperates.On the diametric(al) of spheroid through hole is arranged, connecting rod is the sealing shape and is fixed in this through hole and its two ends extend.The tip side of connecting rod does not have a radially end of outer lug boss near ball seat.Ball seat does not have between end of boss radially and spheroid seal ring is arranged, and the sealing circle is traditional O-ring seals.An end and the seal ring between spheroid of boss are traditional O-ring seals because ball seat does not have radially, and the area of contact of this O-ring seals and spheroid is less, very easily wear and tear with the rotation of spheroid in its contact position, and sealing effectiveness is relatively poor.Sealing effectiveness one is poor, and water and silt just easily enter between ball seat and the spheroid, thereby ball and socket wearing and tearing, service life are shortened.
(3) utility model content
The technical problems to be solved in the utility model provides a kind of ball and socket.This ball and socket, good sealing effect, not easy to wear, service life is longer.
For addressing the above problem, the utility model is taked following technical scheme:
Ball and socket of the present utility model comprises ball seat, spheroid and connecting rod.Ball seat wherein is a sleeve shaped, and the one end has radially outer lug boss, and its medial surface is a sphere.Said spheroid places in the ball seat, and the diameter of its diameter and ball seat medial surface adapts and the two is running-fit.On the diametric(al) of spheroid through hole is arranged, connecting rod is the sealing shape and is fixed in this through hole and its two ends extend.The tip side of connecting rod does not have a radially end of outer lug boss near ball seat.Ball seat does not have between end of boss radially and spheroid regulating ring is arranged, and the medial surface of this regulating ring is a sphere, and outer, negative thread are arranged respectively on the circle on its cylindrical and in the corresponding position of ball seat, the two by outside this, negative thread spins together.There is annular groove the inboard of regulating ring outer end, and seal ring is arranged in the annular groove.Its constructional feature is that said seal ring and the contacted one side of spheroid are sphere, the diameter of this sphere and the equal diameters of spheroid.
Adopt such scheme, have the following advantages:
Because its seal ring of ball and socket of the present utility model and the contacted one side of spheroid are sphere, the diameter of this sphere and the equal diameters of spheroid, the area of contact between seal ring and spheroid is bigger, makes its contact position not easy to wear, and sealing effectiveness is better.Because said seal ring is fixed on by gland in the annular groove of regulating ring,, thereby can improve greatly sealing effectiveness and service life again by the degree of tightness adjustable sealing circle of adjusting gland and the degree of tightness between spheroid.
In addition, because its ball seat of ball and socket of the present utility model does not have radially and between boss one end and link rob head end the taper bellows is arranged, the two ends of this taper bellows respectively with link rob head end and ball seat do not have radially be between outer lug boss one end the sealing shape be connected, so, can prevent further that silt from entering between spheroid and the ball seat.Thereby can further improve sealing effectiveness, increase the service life.
(4) description of drawings
Accompanying drawing is a ball and socket structural representation of the present utility model.
(5) specific embodiment
As shown in drawings, ball and socket of the present utility model contains ball seat 9, spheroid 10 and connecting rod 11.Ball seat 9 wherein is a sleeve shaped, is processed with radially outer lug boss on the circumferencial direction of one end, and its medial surface is a sphere, and said spheroid 10 is installed in the ball seat 9, and makes and be moving type between the medial surface of spheroid 10 and ball seat 9 and cooperate.
Be processed with through hole on the diametric(al) of spheroid 10, this through hole connects along the diametric(al) of spheroid 10.Connecting rod 11 is the sealing shape and penetrates in this through hole.Wherein, be processed with annular groove on the through hole circumferencial direction of spheroid 10, annular groove is embedded with, and inner seal ring 1 can be realized sealing between connecting rod 11 and spheroid 10 through holes by inner seal ring 1.Stretch out outside spheroid 10 at connecting rod 11 two ends, and the one end is a tip side 2.This tip side is in ball seat 9 does not have a radially end of outer lug boss.
