Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.Need to prove; the orientation determiner that waits up and down that occurs in the utility model is reference with the position under the common user mode of position structure tool all; so that understand the bearing cap position structure in the utility model more clearly, but do not limit the protection domain of technical solutions of the utility model.
Shown in Fig. 1 to 6, the utility model bearing cap position structure, comprise that bearing cap 1, bearing support 2 and two ends stretch to the setting sleeve 3 of described bearing cap 1 and described bearing support 2 inside respectively, described bearing cap 1 and bearing support 2 relative sides have the bearing hole round surface that is used to place bearing (bent axle) respectively, and promptly bearing cap 1 is semicircle arc surface with the opposing side of bearing support 2.Wherein, described bearing cap 1 is respectively equipped with a bearing cap positioning spigot 11 in the both sides that are positioned at described bearing hole, and described bearing cap positioning spigot 11 is parallel to the Z axle shown in Fig. 1, be provided with the bearing cap setting sleeve counterbore 12 that cooperates with described setting sleeve 3 being positioned at bearing cap screw via hole 62 ports that semicircle parting plane 4 (being bearing cap 1 and bearing support 2 surface of contact) locates, bearing cap setting sleeve counterbore 12 is coaxial with described bearing cap screw via hole 62.Described bearing support 2 is provided with the bearing support positioning spigot 21 that matches with described bearing cap positioning spigot 11, and being provided with the bearing support setting sleeve counterbore 22 that cooperates with described setting sleeve 3 in the bearing support tapped hole 61 that is positioned at semicircle parting plane 4 places (being provided with screw thread) port with screw coupling, described bearing support setting sleeve counterbore 22 is coaxial with described bearing support tapped hole 61.Utilize two pairs of positioning spigots of bearing hole both sides to realize that bearing cap 1 is along the X-axis translation and the location of rotating three degree of freedom around Y-axis, Z axle in the present embodiment, semicircle parting plane 4 can realize that then bearing cap 1 rotates the location of three degree of freedom along the Y-axis translation and around X-axis, Z axle, and 31 of setting circle segmental arcs realize that bearing cap 1 is along the translation of Z axle and the location of rotating three degree of freedom around X-axis, Z axle.As shown in Figure 2, be respectively equipped with thrust surface 5 with described bearing support 2 towards the one side (being both opposing sides) of described bearing hole at described bearing cap 1 in the present embodiment, and described thrust surface 5 is to get with described bearing support 2 assembling back processing at described bearing cap 1, it is hereby ensured accurate cooperation the between thrust surface 5 and bearing cap 1 and bearing support 2 both surface of contact, even bearing cap position structure repeated disassembled and assembled, do not influence the accuracy of its location yet, further improve the Location accuracy of bearing cap position structure.
Setting sleeve 3 in the present embodiment is compared to prior art, has special construction, shown in Fig. 3 to 6, one end outer wall is provided with the setting circle segmental arc 31 and the arc section 32 of stepping down, the diameter everywhere of the wherein said arc section 32 of stepping down is all less than described setting circle segmental arc 31, and the arc section 32 that promptly guarantees under any circumstance to step down can not contact with described bearing cap 1; And described setting circle segmental arc 31 is to have outstanding two of axial direction (promptly along Z-direction) along bearing hole towards two opposite arc surfaces, and with described bearing cap 1 Spielpassung.The end that described setting sleeve 3 is provided with the described setting circle segmental arc 31 and the arc section 32 of stepping down extends to described bearing cap 1 inside by described bearing support 2 inside, promptly satisfies setting circle segmental arc 31 and steps down arc section 32 across described bearing cap 1 and bearing support 2 surface of contact.Be set to have the setting circle segmental arc 31 that goes out along the Z aixs cylinder by setting sleeve 3 towards an end of bearing cap 1, therefore can realize the location of bearing cap 1 along Z axle translation freedoms; Because the described arc section 32 of stepping down can not impact the mobile or rotation of bearing cap 1, influence has effectively avoided crossing the situation of location simultaneously.Long in the present embodiment for the arc length that prevents described setting circle segmental arc 31 correspondences, and might cause bearing cap 1 to cross the location, therefore preferably what the arc length of setting circle segmental arc 31 correspondences is provided with is short as far as possible, and moves axially along vertical described bearing hole and be as the criterion not influence described bearing cap 1.
In the technique scheme, described setting sleeve 3 closely cooperates with described bearing support 2, described setting sleeve 3 and described bearing cap 1 Spielpassung, promptly satisfying setting sleeve 3 tightly is fixed on the bearing support 2, and setting sleeve 3 and bearing cap 1 are than loose fit, therefore can guarantee when the described bearing cap 1 of plug relatively easily, and the process of plug bearing cap 1 can be with setting sleeve 3 by taking out of in the bearing support 2.
When the bearing cap position structure in the present embodiment is installed, earlier setting sleeve 3 outsides being a complete columnar end squeezes in the bearing support setting sleeve counterbore 22, and two the relative setting circle segmental arcs 31 on setting sleeve 3 the other end sidewalls are positioned on the bearing hole axial direction, then that the bearing cap positioning spigot 11 of bearing cap 1 both sides is corresponding with the bearing support positioning spigot 21 of bearing support 2 both sides, the bearing cap setting sleeve counterbore 12 of bearing cap is corresponding with setting circle segmental arc 31, make bearing cap 1 finish the location and pack into.Passing bearing cap screw via hole 62 by screw 6 at last is screwed in the bearing support tapped hole 61, makes bearing cap 1 and bearing support 2 secure fit between the two.Wherein, as shown in Figure 1,2 semicircle parting planes 4 of bearing cap positioning spigot 11, bearing support positioning spigot 21 and bearing cap 1 and bearing support (being bearing cap 1 and bearing support 2 surface of contact) play positioning bearing lid 1 and reach the positioning action around X, Y, the rotation of Z axle along X, the moving effect of y-axis shift, and the setting circle segmental arc 31 in the setting sleeve 3 plays the effect that positioning bearing lid 1 moves along the Z axle.The utility model has the advantages that accurate positioning and only the location, and the arc section 32 of stepping down in the setting sleeve 3 does not participate in the location of bearing cap 1, so just guarantee not only accurate positioning of bearing cap 1, realized six dimensions (be bearing cap along the moving of X-axis, bearing cap around the rotation of X, bearing cap along the moving of Y-axis, bearing cap around the rotation of Y-axis, bearing cap along X-axis move and bearing cap around the rotation of X-axis) location fully, and don't the phenomenon of location can appear, make installation process convenient simple.Bearing cap position structure in the present embodiment is specially adapted to use the bearing cap of axial thrust bearing.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
