Abstract
The present invention pertains to the field of mechanical technology. A ball-joint intracavity of a totally-enclosed universal joint of a ball joint on which steel balls are evenly arranged in a crossmanner is a ball hole; four semispherical ball pits are arranged thereon in a cross manner; a cylindrical hole and a keyway are arranged on the left side; a screw hole is arranged on the end face; agroove is arranged on the periphery of a big tapered-hole internally arranged on the right side. Four even crescent semispherical grooves are arranged on the outer margin of a ball head along the axial line; a spline groove and a retainer-ring groove are prepared on an inner hole; and the ball head is inserted after a retainer ring is arranged in the retainer-ring groove of the spline shaft to form a ball-head driving axle. The intracavity of the end cap of the end-cap driving axle is a ball hole; a keyway is arranged on the cylindrical face; and a light hole is arranged on a flange ring. Steel balls and ball-head driving shaft are arranged in the ball-joint; the end-cap driving axle is fastened by a socket head cap screw after a flat key is arranged; a plurality of fold jackets are coatedthereon, and a universal joint is achieved by bar clasping; the ball head driving axle can be deflected in four direction by large angle.
Description
Technical field the present invention relates to a kind of Totally-enclosed gimbal of iron shot cross equispaced ball cage.
Background technique is present, and domestic and international existing universal joint mainly contains two classes: a class is a Hooke's joint, and a class is a rzeppa universal joint.The Hooke's joint characteristics are about transmission shaft can be done, left and right sides four direction wide-angle deflection, but the angular velocity of two transmission shafts does not wait after the deflection; The characteristics of rzeppa universal joint are that the transmission shaft deflection angle is little, but two transmission shaft angular velocity after the deflection equate.Two class universal joints cut both ways, and common deficiency is a cross axle as disconnected one jiao, and transmission shaft just may come off; Steel ball is if any breakage, the bulb transmission shaft ball cage of may scurrying out, and both all can cause the accident.
Summary of the invention the purpose of this invention is to provide a kind of Totally-enclosed gimbal of iron shot cross equispaced ball cage that can realize being two transmission shaft isogonisms speed rotation after " ten " word shape four-way wide-angle deflection transmission shaft, the deflection.
The object of the present invention is achieved like this: the hemisphere hole that is slightly larger than the steel ball radius in four crossing of axis systems of two " ten " words in the section upper edge, center in ball cage inner chamber ball hole, ball cage inner chamber left side is shaped on a cylindrical hole and the cylindrical void keyway greater than the ball bore dia, the ball cage is shaped on uniform screw on the left side, and ball cage right side is shaped on big taper hole, periphery is fluted; The spheroid outer rim is slightly less than ball cage inner chamber ball bore dia and has the splined shaft that four uniform crescent shape hemisphere groove, spheroid endoporus that are slightly larger than the steel ball radius are shaped on the bulb of spline and circlip groove and have circlip groove along axis, in the circlip groove of splined shaft, put Steel Cable Baffle Ring, be inserted into and form the bulb transmission shaft after the screens of bulb spline slotted eye back-up ring; The end cap inner chamber of end cap transmission shaft is consistent with the ball hole of ball cage inner chamber, the cylndrical surface is slightly less than the cylinder aperture of ball cage, have a shaft spline on it, have on its flange circle with ball cage left side on the consistent unthreaded hole of screwhole position, (also the end cap transmission shaft can be divided into end cap and transmission shaft, connect) with spline and back-up ring.In ball cage inner chamber hemisphere hole, pack into steel ball and bulb transmission shaft, behind the dress flat key itself and ball cage are cooperated in the shaft spline of end cap transmission shaft, tighten up with socket head screw, ball cage right side puts many folding sheaths, use collar clamped, Totally-enclosed gimbal of iron shot cross equispaced ball cage.
Owing to adopt such scheme, its characteristics with have the effect covered to be: 1. the steel ball of bulb transmission shaft mat invariant position in the ball cage, can be by " ten " font four-way wide-angle deflection, and the angular velocity of rotation of two transmission shafts equates after the deflection, has concentrated cross axle and rzeppa universal joint advantage separately; 2. this universal joint adopts and divides body structure, not only makes forging ball cage, bulb, even the work simplification of end cap, and machining is more convenient, has also adopted many universal standard parts, and manufacture cost is reduced; 3. the bulb transmission shaft is sealed with ball cage and end cap, easily preserves lubricating grease, even and the steel ball breakage, the bulb transmission shaft can not fall from the ball cage yet, uses more safe and reliable; 4. with many folding sheath waterproof and dustproofs, guarantee the flexible deflection and the working life of universal joint.
Description of drawings Fig. 1 is a structural principle sketch of the present invention.Among the figure: 1. ball cage; 2. steel ball; 3. flat key; 4. end cap transmission shaft; 5. bulb; 6. splined shaft; 7. Steel Cable Baffle Ring; 8. socket head screw; 9. clip; 10. roll over sheath more.
Embodiment describes embodiments of the invention in detail below in conjunction with accompanying drawing 1.
Among Fig. 1, be shaped on four at the crossing axis of two " ten " words in the section upper edge, center, inner chamber ball hole of ball cage 1 and be the uniform hemisphere hole that is slightly larger than steel ball 2 radiuses of " ten " word, ball cage 1 inner chamber left side is shaped on a cylindrical hole and the cylindrical void keyway greater than the ball bore dia, be shaped on uniform screw (representing with partial cutaway among the figure) on ball cage 1 left side, to be not less than 90 ° taper hole, periphery fluted for the system cone angle in ball cage 1 right side; Bulb 5 outer rims are slightly less than ball cage 1 inner chamber ball bore dia, offer four uniform crescent shape hemisphere grooves that are slightly larger than steel ball 2 radiuses, bulb 5 endoporus system spline and circlip grooves along axial direction thereon; In the circlip groove of splined shaft 6, put Steel Cable Baffle Ring 7, splined shaft 6 inserted the spline slotted eye of bulbs 5, Steel Cable Baffle Ring 7 screens in the circlip groove of bulb 5 fixing the bulb transmission shaft; The end cap inner chamber of end cap transmission shaft 4 is consistent with the ball hole of ball cage 1 inner chamber, its cylndrical surface is slightly less than the cylindrical hole diameter of ball cage 1 and has a shaft spline thereon, have on its flange circle with ball cage 1 left side on the consistent unthreaded hole of screwhole position, also end cap transmission shaft 4 can be divided into the transmission shaft that the end cap that is shaped on the spline slotted eye and spindle nose are shaped on spline and circlip groove, both are with splined, back-up ring location.Steel ball 2 and bulb transmission shaft 5.6.7 pack in ball cage 1 inner chamber hemisphere hole, behind the dress flat key 3 it is cooperated with ball cage 1 in the shaft spline of end cap transmission shaft 4, tighten up with socket head screw 8, ball cage 1 right side puts many folding sheaths 10, with clip 9 it is fixed tightly in the groove of ball cage 1 periphery, promptly forms Totally-enclosed gimbal of iron shot cross equispaced ball cage.
As seen from Figure 1, end cap transmission shaft 4 transmits moment of torsion, by flat key 3 through ball cage 1 to steel ball 2, reach bulb transmission shaft 5.6.7 again, even steel ball 2 breakages, the bulb transmission shaft can not fall from the ball cage yet.When the external world needs bulb transmission shaft deflection angle, this universal energy-conservation making an immediate response, or do to go up deflect around two steel balls of horizontal positioned, or do left and right sides deflection around two steel balls of vertical placement, fixed big cone angle is enough to meet the requirement that external environment condition changes.
