Abstract
A rigidity-improved spherical hinge comprises a rubber layer, a mandrel and an outer cover. Outward-protruding circular-arc sections protruding towards the outer side are arranged on the two sides of a main circular-arc section of the periphery of the mandrel, the circular-arc radius of the outward-protruding circular-arc sections is smaller than that of the main circular-arc section, and inward-concave circular-arc sections concaved towards the inner side are arranged on the outer sides of the outward-protruding circular-arc sections. The outward-protruding circular-arc sections protruding towards the outer side are cut on the two sides of the main circular-arc section of the mandrel, the inward-concave circular-arc sections concaved towards the inner side are cut on the outer sides of the outward-protruding circular-arc sections, and thus the structure of the rubber layer vulcanized on the mandrel is changed accordingly. The rigidity of the spherical hinge is improved by changing the structures of the mandrel and the rubber layer in the spherical hinge. The dimension of an opening of the spherical hinge is increased due to the outward-protruding circular-arc sections and the inward-concave circular-arc sections; besides, the main circular-arc section, the outward-protruding circular-arc sections and the inward-concave circular-arc sections are in smooth transition so that the strain of the rubber layer can be effectively reduced, and thus the anti-fatigue performance and the stability of the product can be improved.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is done the description of a step:
Embodiment one
As depicted in figs. 1 and 2, the overcoat 1 of ball pivot, rubber layer 2 and mandrel 3 are all rotary bodies, and overcoat 1 and mandrel 3 are metal parts, and overcoat 1 and mandrel 3 sulfide with rubber layer 2.The peripheral surface of mandrel 3 includes main arc section 31, evagination arc section 32, indent arc section 33 and annular flat straight section 34.The both sides of main arc section 31 are provided with 2 sections of evagination arc sections 32 protruded laterally, but the arc radius of evagination arc section 32 is less than the arc radius of main arc section 31.The outside of evagination arc section 32 is provided with the indent arc section 33 to inner side depression, and the outside of indent arc section 33 is additionally provided with annular flat straight section 34.
The most main arc section 31, evagination arc section 32 and indent arc section 33 are all circular structures, and its longitudinal section is all circular arc.Annular flat straight section 34 is also round ring-type structure, but its longitudinal section is line segment.The inner side of evagination arc section 32 is connected with main arc section 31, and the outside of evagination arc section 32 is connected with indent arc section 33, and the outside of indent arc section 33 is connected with annular flat straight section 34.
And the evagination arc section 32 of main arc section 31 and both sides all forms smooth transition in junction, evagination arc section 32 and indent arc section 33 form smooth transition in junction, indent arc section 33 and the annular flat straight section 34 of indent arc section 33 forms smooth transition in junction, and indent arc section 33 and annular flat straight section 34 form smooth transition in junction.
Main arc section 31, evagination arc section 32, indent arc section 33 and annular flat straight section 34 is allowed to form smooth transition in junction, primarily to prevent rubber layer 2 when the extruding by load deforms upon, stress within rubber layer 2 is concentrated, make rubber layer 2 easily produce tired and split, lose original performance.It is to say, allow each junction form smooth transition be mainly the anti-fatigue performance of high product.
Comparative example one
As shown in Fig. 3 and Fig. 2, in the longitudinal section of overcoat 1, rubber layer 2 and mandrel 3, shown in the A curve during the longitudinal section of the outer surface of mandrel 3 is figure before this invention, the outer surface of mandrel 3 only has main arc section 31 and annular flat straight section 34.And the longitudinal section of the outer surface of the mandrel 3 of the present invention is shown in the B curve in figure, the outer surface of mandrel 3 includes main arc section 31, evagination arc section 32, indent arc section 33 and annular flat straight section 34.
Arc radius due to evagination arc section 32 is less than the arc radius of main arc section 31, therefore, although evagination arc section 32 is protruding laterally but still in the inner side of original main arc section 31.Evagination arc section 32 increases the size of the rubber layer 2 of ball pivot opening part together with indent arc section 33, thus effectively reduces the strain of rubber layer 2, improves the rigidity of ball pivot.
As shown in Figure 4, present invention stiffness curve under static load is C, and the stiffness curve under static load of the product before improving original structure is D.Time from stiffness curve it can be seen that produce the deformation of same journey, the present invention can bear bigger load, say, that the rigidity of the present invention improves relative to original structure.
In sum, current ball pivot, the patent of skew correlation are all to use change product end profiles to realize the raising fatigue behaviour present invention being then to realize improving rigidity, improving fatigue behaviour by change interiors of products profile；And change product end profiles mainly improves tired effect by the fold after adjusting product stress deformation at present, and the present invention can be by reducing rubber hardness, and reduction interiors of products stress carrys out the tired effect of improving product.
It will be apparent that on the premise of without departing from principle of the present invention, the some improvement made or modification are regarded as protection scope of the present invention.
