Abstract
The invention belongs to the technical field of machinery, and a totally enclosed universal joint of a double-ball cage and eight steel balls comprises an integrated double-ball cage, steel balls, a ball-end shaft, end covers, a folded sheath and a hexagon socket screw. The inner cavity of the integrated double-ball cage is of a hemispheric hole and a cylindrical hole. Four hemispheric pits uniformly distributed in cross shape are in the left and the right ball cages, and the left cross shape and the right cross shape mutually deflect 45 degrees. Two ends of the ball cage are provided with screw holes, and the ball end of the ball-end shaft has four crescent-shaped hemisphere grooves uniformly distributed along a shaft line. Inner hemisphere holes of the left and the right end covers are consistent with the hemispheric hole of the ball cage. An outer cylindrical surface is consistent with the diameter of the cylindrical hole in the ball cage, a shaft hole position is provided with a big taper hole, and a flange edge is provided with an unthreaded hole. Steel balls and the ball-end shaft are arranged in the ball cage, the end covers are covered, the folded sheath is sheathed and a screw is tightly fixed, which forms the universal joint. The ball-end shaft can be deflected according to the shape like the Chinese character mi and eight directions.
Description
Technical field the invention belongs to field of mechanical technique.
Background technique is present, and domestic and international existing universal joint mainly contains two big classes: a class is " ten " cabinet frame type universal joint, and a class is a rzeppa universal joint.The rzeppa universal joint kind is a lot, and each is variant for function, and what use morely is five steel balls, six steel ball rzeppa universal joints.The advantage of rzeppa universal joint is the axial arrangement compactness, and shortcoming is that the transmission shaft deflection angle is little, and the space between steel ball and the steel ball groove is very big, can clash in the moment of transmitting torque, not only produce the bump sound, also easily make steel ball bump damage even broken, ball journal is scurried out, and causes the accident.
Summary of the invention the purpose of this invention is to provide a kind of energy and realizes being " rice " word shape eight is only deposited glade plane space between wide-angle deflection transmission shaft, steel ball and steel ball groove double ball cage eight-iron-ball totally-enclosed cardan joint.
The object of the present invention is achieved like this: the left and right sides inner chamber of the two ball cages of integral type all is identical hemisphere hole and a cylindrical hole of radius, in left ball cage hemisphere hole and cylindrical hole intersection, be shaped on four and be the uniform hemisphere hole identical of " ten " word with the steel ball radius, equally, in right ball cage, be shaped on the uniform hemisphere hole deflection 45 of four left relatively ball cages " ten " word, be the uniform hemisphere hole of " ten " word, on the end face of left and right ball cage, be shaped on uniform screw.The bulb upper edge axis of two ball heads is offered four uniform, consistent with steel ball radius crescent shape hemisphere grooves.Left and right end cap inner chamber hemisphere hole is consistent with ball cage hemisphere hole, and its external cylindrical surface is consistent with the cylindrical hole of ball cage, and its axis hole place is provided with big taper hole, its flange edge establish with ball cage end face on the uniform consistent unthreaded hole of screwhole position.Pack in ball cage inner chamber hemisphere hole steel ball and ball head cover end cap, put many folding sheaths, tighten up with many foldings sheath with socket head screw or outer-hexagonal eye bolt, double ball cage eight-iron-ball totally-enclosed cardan joint.
Because adopt such scheme, its characteristics and beneficial effect are: 1. left and right ball head can be by " rice " font eight to deflection in integral type pair ball cages, when ball head is influenced by external force to need deflection angle, can adapt to automatically rapidly; 2. steel ball is only deposited glade plane space in ball cage inner chamber hemisphere hole and ball head crescent shape hemisphere groove, therefore can not clash into transmitting torque moment, does not have noise, and steel ball is not fragile yet; 3. ball head is sealed with end cap, even the steel ball breakage, ball head can not fall from the ball cage yet, uses more safe and reliable; 4. with many folding sheath water proof and dust proofs, 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. two ball cages of integral type; 2. steel ball; 3. end cap; 4. socket head screw; 5. ball head; 6. roll over sheath more.
Embodiment describes embodiments of the invention in detail below in conjunction with accompanying drawing 1.
Among Fig. 1, on same axis, a left side is arranged, the two ball cages (1) of the integral type of right symmetry, a left side, the inner chamber of right ball cage is identical hemisphere hole and a cylindrical hole of radius, hemisphere hole and cylindrical hole intersection at left ball cage, being shaped on four, to be " ten " word uniform, the hemisphere hole identical with steel ball (2) radius, hemisphere hole and cylindrical hole intersection at right ball cage, be shaped on the uniform hemisphere hole deflection 45 of four left relatively ball cages " ten " word equally, be the uniform hemisphere hole of " ten " word, from axially, a left side, it is uniform that eight hemisphere holes of right ball cage inner chamber are " rice " word shape, on a left side, respectively be shaped on uniform screw on the end face of right ball cage.The bulb radius of right, right ball head (5) is slightly less than the hemisphere pore radius of the two ball cages (1) of integral type, and offer four uniform, consistent crescent shape hemisphere grooves with steel ball (2) radius at its bulb upper edge axial direction, the length of this four groove needs the maximum angle of deflection to determine by ball head (5), goes up the system spline at the axle of ball head (5) as required.The hemisphere hole of left and right end cap (3) inner chamber is consistent with two ball cage (1) the inner chamber hemisphere holes of integral type, its outer cylinder is consistent with the cylindrical hole of two ball cage (1) inner chambers of integral type, the axis hole place needs the maximum angle of deflection to make taper hole by ball head (5), its flange edge establish with two ball cage (1) end faces of integral type on the unthreaded hole of uniform consistent, the equipped screw of screwhole position.Many folding sheaths (6) are made one with the metal gasket of rubber-plastics material and screw (4) joint.Eight steel balls (2) of in two ball cage (1) the inner chamber hemisphere of integral type hole, packing into, the left and right ball head (5) that is respectively charged into, cover end cap (3), put many folding sheaths (6), end cap (3) and many folding sheaths (6) are tightened up with the two ball cages (1) of integral type together with socket head screw (4).Also available outer-hexagonal eye bolt tightens up, and steel wire is revolved knot after passing hole on each outer-hexagonal head with steel wire, in case bolt looseness.Like this, ball head (5) just is enclosed in the ball cage with steel ball (2).
From the right half part of Fig. 1 as can be seen, the position of steel ball in ball cage hemisphere hole is forever constant, when ball head (5) in the time of will going up deflect, ball head (5) is around two steel balls (2) rotation of horizontal positioned, when ball head (5) was wanted left and right sides deflection, ball head (5) was around two steel balls (2) rotation of vertical placement.The left-half steel ball is identical with the operating principle of ball head (5) deflection.Moment of torsion is by eight steel ball transmission.
