Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, carry external screw thread, conical surface P and flat T on axostylus axostyle 3 of the present utility model, external screw thread with
Power 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
Stepped 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 axle
The screw thread spindle nose of bar 3 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, threaded connection
Form 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 is logical with lower ball-and-socket 9
Cross taper pin 1 felt relieved, be spacing, the lower bottom of ball-and-socket 9 uses closed design, can form oil storage oil pocket N；The bottom of lower ball-and-socket 9
There is the installation positioning spigot Q supporting with support base 10 in outside, with high-strength screw 7 and elastic washer 8 by upper ball-and-socket 2 and lower ball-and-socket
9 are fastened on support base 10 together；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 and axostylus axostyle
Conical surface P on 3 coordinates, and 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
Portion, external seal cover 6 vulcanize making together with metallic framework and polyurethane.
To ensure machining accuracy, shock resistance and tensile strength of the present utility model, axostylus axostyle 3 and the split of steel ball 4 are designed, axle
It is integral by the centering of inside and outside step surface, internal and external threads smearing high intensity screw thread gemel connection after bar 3 is processed respectively with steel ball 4,
The original precision of steel ball 4 is made full use of, so that the overall precision of club body is effectively ensured.Upper ball-and-socket 2, lower ball-and-socket 9 are also adopted simultaneously
Split is taken to design, use is corrosion-resistant, wear-resistant quenched material, overall finishing processing again after the first rough turn processing of split, is connect with steel ball 4
Tactile 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 enter in the end face of two parts
The same labelled notation of row, 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 with
The contact precision on the surface of steel ball 4.During assembling, appropriate advanced lubrication fat is smeared in lower ball-and-socket 9, by club body（Axostylus axostyle 3, steel ball
4）Load, identify identical number mark, install ball-and-socket 2, felt relieved by taper pin 1, be spacing, form a complete sphere and slide
It is secondary.
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.
