Abstract
A trifurcate universal joint for a double-spherical rolling wheel comprises a three-pin shaft frame; three uniformly arranged three-pin shafts are arranged on the three-pin shaft frame; through holes which enable spline shafts to be installed are formed inside the three-pin shafts; spherical ring assemblies which are assembled through inner rings and outer rings are installed on the three-pin shafts through rolling pins; external ends of the spherical ring assemblies and the rolling pins are provided with elastic blocking rings which can block the spherical assemblies from moving outward; snap springs are arranged outside the elastic blocking rings; the inner rings and the outer rings of the spherical ring assemblies and spherical surfaces are matched together in a rotatable mode through respective spherical surfaces; a hub of the three-pin shaft frame is designed to be in a spherical inclined surface. The trifurcate universal joint for the double-spherical rolling wheel has the advantages of being simple in structure, convenient to use and install and large in rotating angle, reducing abrasion, improving using intensity and the like.
Description
Technical field
The utility model relates to the fork universal joint universal joint of a kind of pair of sphere roller.
Background technique
In prior art, fork universal joint mainly contains spherical axial triradius universal joint and Three-fork universal joint of cylindrical shaft, wherein spherical fork universal joint is mainly made up of spherical three bearing pins and ball (approximate bearing) etc., between its spherical three bearing pins and ball endoporus, be that point or line contact, be applied in engineering machinery movement process, exist that intensity is low, poor rigidity, the defect such as easy to wear; Another kind of Three-fork universal joint of cylindrical shaft is mainly made up of cylinder axis three bearing pins and ball (logical annulus) etc., its cylinder axis is mainly realized gimbal function with self by ball and three post shells, and between cylinder axis and ball, do not have angled swing, realize and rotating and longitudinal movement and only have by needle roller.
Model utility content
The purpose of this utility model is to overcome the deficiency that prior art exists, and the fork universal joint of a kind of pair of sphere roller is provided; It can solve that the rotation angle of the Three-fork universal joint of cylindrical shaft existing in prior art is little and spherical fork universal joint is easy to wear and the problem such as intensity is low preferably.
The purpose of this utility model is solved by following technical proposals: it includes one or three bearing pin framves, three three uniform bearing pins are set on this three bearing pins frame, the inside of three bearing pin framves is provided with the through hole that can pack splined shaft into, on three described bearing pins, by needle roller, the one ball assembly being assembled by interior ring, outer shroud is installed, the outer end of described ball assembly and needle roller is provided with can block the circlip that ball assembly moves outward, and circlip is provided with jump ring outward.
Between the interior ring of described ball assembly and outer shroud, be mutually rotatably combined together by sphere and sphere separately; The flower-drum of described three bearing pin framves is set to spherical inclined-plane.
The through hole both ends of the surface of described three bearing pin framves are provided with the chamfering of being convenient to assembling.
The utility model is mainly to utilize in ball assembly between ring and outer shroud can mutually rotate between sphere and sphere, and contacting between sphere and sphere, in having increased rotational angle, also increased intensity, rigidity and the durability of product.
The utility model by having increased an interior ball on the ball of common spider, and the increase that can not only play angle of swing has also increased the performances such as the intensity of product, has simple in structure, easy to install and use, rotation angle is large, reduces wearing and tearing, has improved the features such as working strength.
Brief description of the drawings
Fig. 1 is integral installation structural representation of the present utility model;
Fig. 2 is the structural representation of three bearing pins described in the utility model;
Fig. 3 is the side schematic view of three bearing pins described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is shown in detailed introduction: Fig. 1,2,3, the fork universal joint of described in the utility model pair of sphere roller, it includes one or three bearing pin framves 11, the inside that three three uniform bearing pin 1, three bearing pin framves 11 are set on this three bearing pins frame 11 is provided with the through hole 7 that can pack splined shaft 12 into; On three described bearing pins 1, by needle roller 6, a ball assembly being assembled by interior ring 3, outer shroud 2 is installed, the outer end of described ball assembly and needle roller 6 is provided with can block the circlip 4 that ball assembly moves outward, the outer jump ring 5 that is provided with of circlip 4.
Between the interior ring 3 of described ball assembly and outer shroud 2, be mutually rotatably combined together by sphere and sphere separately; The flower-drum of described three bearing pin framves 1 is set to spherical inclined-plane 10.
Through hole 7 both ends of the surface of described three bearing pin framves 1 are provided with the chamfering 8,9 of being convenient to assembling.
Three bearing pin framves and three bearing pins are entirety manufacture, and its heat treatment has adopted Carburization Treatment, surface and endoporus spline hardness HRC58-62, and all case depth 1.2-1.5mm, carburizing and quenching is organized 2-4 level, core structure 1-3 level, centre hardness HRC40-45; Its uses in mechanical engineering time can bear larger power, not easy to wear, twist off, fracture, long service life,
The flower-drum of described three bearing pin framves is made as spherical inclined-plane, and it is processed puts just, beautiful shape, self rotate stressed evenly.
Through hole two ends in three described bearing pin framves are provided with chamfering, arrange chamfering be convenient to acute angle incised wound employee, to mutually the damaging of product, put simultaneously and be convenient to assembling.
When use, at the in-built upper spline axle of through hole 7 of three bearing pin framves 11, on three three bearing pins, ball assembly, needle roller, back-up ring, jump ring are housed respectively, more whole universal joint is encased in housing.
