Flat.
The present invention compared with prior art, the increased external seal cover design of institute, makes ball socket bearing have preferably dust-proof and profit
Slip energy, the complicated working environment in field is adapted to, suitable application area is more extensive, and service life is longer, has Self-aligning, anti-impact
Hit with stretch capability it is high, easy for installation the features such as.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Fig. 2 is Fig. 1 top view.
Fig. 3 is Fig. 1 E-E sectional views.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, with external screw thread, conical surface P and flat T, external screw thread and power on axostylus axostyle 3 of the invention
Source connects, and flat T is used for spanner rotary shaft 3；The top of steel ball 4 cuts with a plane H, and the central upper portion of steel ball 4 carries step
Hole, with the Step Shaft being engaged with the stepped hole of steel ball 4 on axostylus axostyle 3, the Center of steel ball 4 has screwed hole, with axostylus axostyle 3
Screw thread spindle nose coordinates, and the bottom of steel ball 4 is in complete formula sphere, and steel ball 4 is felt relieved with axostylus axostyle 3 by step surface, and threaded connection is formed
Club body；Steel ball 4 is stood on lower ball-and-socket 9, and upper ball-and-socket 2 is pressed on steel ball 4 through axostylus axostyle 3, and upper ball-and-socket 2 passes through cone with lower ball-and-socket 9
Pin 1 is felt relieved, is spacing, and the lower bottom of ball-and-socket 9 uses closed design, can form oil storage oil pocket N；The bottom outside of lower ball-and-socket 9
There is the installation positioning spigot Q supporting with support base 10, with high-strength screw 7 and elastic washer 8 by upper ball-and-socket 2 and lower ball-and-socket 9 one
Rise and be fastened on support base 10；The upper end oral area of upper ball-and-socket 2 is equipped with M shape reverse buckling types inner seal cover 5, inner seal cover 5 with axostylus axostyle 3
Conical surface P coordinate, inner seal cover 5 makes of chloroprene rubber material；External seal cover 6 is enclosed on outside inner seal cover 5 through axostylus axostyle 3,
External seal cover 6 vulcanizes making together with metallic framework and polyurethane.
To ensure machining accuracy, shock resistance and the tensile strength of the present invention, axostylus axostyle 3 and the split of steel ball 4 are designed, axostylus axostyle 3
It is integral by the centering of inside and outside step surface, internal and external threads smearing high intensity screw thread gemel connection after being processed respectively with steel ball 4, fully
Using the original precision of steel ball 4, so that the overall precision of club body is effectively ensured.Upper ball-and-socket 2, lower ball-and-socket 9 are also taken point simultaneously
Body designs, and use is corrosion-resistant, wear-resistant quenched material, overall finishing processing again after the first rough turn processing of split, is contacted with steel ball 4
Upper ball-and-socket 2, lower ball-and-socket 9 first carry out integral quenching, then carry out thick, fine grinding and attrition process, and are carried out together in the end face of two parts
Labelled notation, so as to which the uniformity of two ball-and-socket dimensional accuracies and geometric accuracy be effectively ensured, improve ball-and-socket Internal Spherical Surface and steel ball 4
The contact precision on surface.During assembling, appropriate advanced lubrication fat is smeared in lower ball-and-socket 9, by club body（Axostylus axostyle 3, steel ball 4）Dress
Enter, identify identical number mark, install ball-and-socket 2, felt relieved by taper pin 1, be spacing, form a complete sphere sliding pair.
Inner seal cover 5 is mounted in the upper end oral area of upper ball-and-socket 2, external seal cover 6 is enclosed on outside inner seal cover 5 through axostylus axostyle 3,
Form completely enclosed dust-proof, lubricating system；Lower ball-and-socket 9 is felt relieved with support base 10 by positioning spigot Q, is spacing, then by high-strength
Upper ball-and-socket 2 and lower ball-and-socket 9 are fastened on support base 10 by degree screw 7 and elastic washer 8 together.During work, club body（Axostylus axostyle 3,
Steel ball 4）It is threadedly attached on power source, (oscillating motion, tilts and transport according to the Different Exercise Mode exported on power source
Dynamic, rotary motion), the motion of different modes can be realized in the range of certain angle.
Because ball socket bearing is first to carry out split type roughing, overall finishing and componentized assembling after reassembling, therebetween
Gap is by facing-up, the detection control of micron table, and the contact precision for sliding sphere is higher（More than more than 80%）, circular error and table
Surface roughness can be fully ensured that, completely enclosed dust-proof, lubricating system are formed by double-layer seal, enables ball socket bearing
Preferable flexibility of revolution is kept for a long time, overcomes the defects of original structure does not adapt to field work environment.
