Abstract
The invention belongs to the technical field of machineries. A double ball-end shaft cylindrical wedge axle pin type universal joint, which comprises a whole double spherical shell, a ball-end shaft, a cylindrical wedge, a pin, a needle roller, a cage assembly and an elastic retainer ring for holes, wherein the double spherical shell is an integrated body, and the ball-end shafts are put in a left and a right symmetrical hemisphere holes. The cylindrical wedge is arranged in a ball end of the ball-end shaft, and a pin hole whose axis has an inclined angle is arranged in the cylindrical wedge. The spherical shell and the ball-end shaft are connected by the pin, the needle roller and the cage assembly supports the pin, and the elastic retainer ring for holes is located in an axial direction. The ball-end shaft surrounds the pin to achieve large angle deflection in upper, lower, left and right, the ball-end shaft depends on the cylindrical wedge to achieve swing and rotating in any small angles, and the torque is transmitted by the pin.
Description
Technical field the invention belongs to field of mechanical technique.
Background technique is present, and domestic and international existing universal joint has two big classes, and the one, " ten " cabinet frame shape universal joint, the one, rzeppa universal joint." ten " cabinet frame shape universal joint can only be realized four direction deflection transmission shaft, and " a ten " cabinet frame adds the universal energy-conservation realization six direction deflection transmission shaft of a pivot pin again, eight direction deflection of two universal energy-conservation realizations of " ten " cabinet frame shape transmission shaft.Along with the axial increase of deflection transmission, its structure is got over complicated, and axial dimension is also increasing.And really can realize universal universal joint, also do not have at present.
Summary of the invention the purpose of this invention is to provide a kind of existing Rzeppa type " ten " cabinet frame shape structural feature again, can realize the double ball head axis cylindrical wedge axial pin type cardan universal joint of universal deflection transmission shaft.
The object of the present invention is achieved like this: at the left and right inner chamber system hemisphere hole and the cylindrical hole of whole double spherical shell, establish forward and backward each cylinder boss of one in left spherical shell outside along horizontal axis, in cylinder boss, make blind hole and through hole respectively, and make two big breach of upper and lower unanimity in the cylindrical hole side of spherical shell along axis; Equally, make blind hole and through hole along vertical axis respectively in upper and lower each cylinder boss of one, make two big breach of forward and backward unanimity in spherical shell cylindrical hole side in right spherical shell outside.System is perpendicular to ball head axis and the cylindrical hole by the centre of sphere on the bulb of ball head.Cylinder wedge two ends are and the consistent sphere of ball head bulb radius, and with cylinder wedge axis tilt several angle system pivot hole.Pivot pin two cooperates with the needle bearing internal diameter, and the middle part cooperates with pivot hole in the cylinder wedge.
About whole double spherical shell, the place puts into needle bearing earlier in the cylinder boss blind hole, be respectively charged into the ball head that has packed into the cylinder wedge again, insert pivot pin, the needle bearing of packing in spherical shell cylinder boss through hole, make axially locating with circlip for hole, promptly form double ball head axis cylindrical wedge axial pin type cardan universal joint, by the pivot pin transmitting torque.
Because adopt such scheme, its characteristics and beneficial effect are: 1. from axially, left and right sides pivot pin has been formed " ten " cabinet frame shape, and two ball heads are subjected to external force to do the four direction deflection of wide-angle upper and lower, left and right around pivot pin; 2. when ball head is subjected to external force to reach the cylinder wedge, can make ball head lean on the cylinder wedge to make the rotation of small angle any direction; 3. whole double spherical shell structure makes the universal joint axial dimension little, and the extraneous variation of universal flexible adaptation, thereby Applicable scope is wider.
Description of drawings Fig. 1 is a structural principle sketch of the present invention.Among the figure: 1. whole double spherical shell; 2. pivot pin; 3. needle roller and retainer assembly; 4. ball head; 5. cylinder wedge; 6. circlip for hole.
Embodiment describes embodiments of the invention in detail below in conjunction with accompanying drawing 1.
Among Fig. 1, on the same axis of whole double spherical shell (1), left and right spherical shell is with same radius system hemisphere hole and cylindrical hole, in hemisphere hole and cylindrical hole intersection, spherical shell outside, a left side is provided with forward and backward each cylinder boss along horizontal axis, make blind hole and the through hole of adorning needle roller and retainer assembly (3) respectively along the cylinder boss axis,, be shaped on two big breach of upper and lower unanimity in spherical shell cylindrical hole side.Equally, be provided with upper and lower each cylinder boss along vertical axis, in cylinder boss, make blind hole and through hole,, be shaped on two big breach of forward and backward unanimity in spherical shell cylindrical hole side in right spherical shell outside.The bulb radius of ball head (4) is slightly less than the radius in spherical shell hemisphere hole, and system is made spline perpendicular to the ball head axis, by the cylindrical hole of the centre of sphere on the axle of ball head as required on bulb.The diameter of cylinder wedge (5) is slightly less than the cylinder aperture on the ball head (4), and its two ends are and the consistent sphere of ball head (4) bulb radius, at the pivot hole that is shaped on the inclination several angle by cylinder wedge (5) axis.Pivot pin (2) two cooperates with the internal diameter of needle roller and retainer assembly (3), and the middle part diameter is slightly less than the pivot pin aperture in the cylinder wedge (5).
Cylinder boss blind hole place about whole double spherical shell (1) puts needle roller and retainer assembly (3) earlier well, be respectively charged into the ball head (4) that packs into cylinder wedge (5), insert pivot pin (2), pack in spherical shell cylinder boss through hole needle roller and retainer assembly (3), make axially locating with the hole with elastic scheibe (6), or at spherical shell exterior cylindrical boss through hole system internal thread, screw in plug screw and make axially locating, double ball head axis cylindrical wedge axial pin type cardan universal joint.
Claims (2)
1. double ball head axis cylindrical wedge axial pin type cardan universal joint, needle roller and retainer assembly are arranged, the hole elastic scheibe, it is characterized in that in addition hemisphere hole and cylindrical hole by left and right symmetry constitutes inner chamber, left spherical shell outside is provided with forward and backward cylinder boss along horizontal axis, and system blind hole and through hole, the cylindrical hole side is upper and lower to be shaped on big breach, and right spherical shell outside is provided with upper and lower cylinder boss along vertical axis and also makes blind hole and through hole, the forward and backward whole double spherical shell that is shaped on big breach of cylindrical hole side; With the axis normal of ball head and be shaped on the ball head of cylindrical hole by the centre of sphere; Be shaped on the cylinder wedge of pivot hole and two and needle roller and retainer assembly endoporus cooperate, the middle part penetrates the cylinder wedge pivot pin with cylinder axis deflection one angle.
2. double ball head axis cylindrical wedge axial pin type cardan universal joint according to claim 1 is characterized in that at whole double spherical shell exterior cylindrical boss through hole system internal thread, screws in cock and makes axially locating.
