Abstract
A flat ball type three layer combined slide bearing comprises an outer sleeve and an intermediate sleeve, wherein, the intermediate sleeve is positioned in the outer sleeve, which are in spherical sliding fit; one end of the inside of the outer sleeve is provided with an axial built-in groove; an inner sleeve is encased in the intermediate sleeve, which are in sliding fit; one end of the inner sleeve is provided with an outer convex rim, and the inner side of the intermediate sleeve is provided with a concave rim fit with the outer convex rim; a radial oil feeding hole is arranged on the outer sleeve and the intermediate sleeve; the outer end of the oil feeding hole is provided with a ring-shaped groove along the circumference of the outer sleeve and the intermediate sleeve. As the friction between the intermediate sleeve and the outer sleeve of the utility model is comparatively large, the intermediate sleeve and the outer sleeve do not rotate relatively, and the slid surface of the bearing is changed into the cylindrical surface between the inner sleeve and the intermediate sleeve to decrease the contact area of the two ones, therefore, the friction is reduced. To the situation having axial force, the axial force and the radial force respectively act on one side of the peripheral surface and the outer convex rim of the inner sleeve, and the respective pressure does not form composite force like the spherical surface so as to reduce the friction, therefore, the utility model has the advantages of flexible rotation, little rotating friction and accurate axial positioning, and the life-span is also greatly prolonged.
Description
Technical field
The utility model relates to spherical bearing, specifically is the box-like sliding bearing of a kind of linner ball type three-layered node.
Background technique
Existing two laminar spherical bearings are made of overcoat and interior cover, are slidingly matched for sphere between the two.When spherical diameter increased, interior overcoat friction area increased, and the pivoting friction resistance is increased, and caused rotating dumb.When this bearing was subjected to thrust load, this thrust load was born by a side sphere of interior cover simultaneously; Thereby the force-bearing situation of cover is poorer in making, and existing pivoting friction resistance has axial one-sided pressure again, makes the rotation frictional resistance bigger, the ball type of contact surface serious wear of interior overcoat, and cover is gone out in causing, and axially locating can't accurately realize.
Summary of the invention
The purpose of this utility model just provide a kind ofly reduce axial rub, rotate flexibly, the little box-like sliding bearing of linner ball type three-layered node of wearing and tearing.
The technical solution of the utility model is: comprise overcoat and middle cover, middle cover is positioned within the overcoat, be slidingly matched for sphere between the two, end in the overcoat inboard has the axial groove of inserting, in described centre, be with interior cover, be slidingly matched between the two, cover one end has an outward flange in this, and the recessed edge that cooperates with described outward flange is arranged in the middle cover inboard; Oil hole is radially arranged on overcoat and middle cover, have along the annular groove of overcoat and middle cover circumference in the outer end of this oil hole.
Described oil hole has three and be uniformly distributed along the circumference.
Because frictional force is bigger, so do not relatively rotate, the slip surface of bearing changes the cylndrical surface between interior cover and the middle cover into, has reduced both area of contact, so frictional force reduces between middle cover of the present utility model and the overcoat.For the situation that axial force is arranged, axial force and radial force act on side face and interior cover outward flange one side respectively, pressure does not separately resemble to form the sphere makes a concerted effort, its frictional force reduces, rotate flexibly so the utlity model has, the rotation frictional resistance is little, axially fixed advantage accurately, and also prolong greatly working life.

Embodiment
Referring to Fig. 1-Fig. 5, the utility model comprises overcoat 1, middle cover 2 and interior cover 3, and middle cover 2 is positioned within the overcoat 1, is slidingly matched for tighter sphere between the two, end in the inboard of overcoat 1 has the axial groove 11 of inserting, and is used for middle cover 2 is put into overcoat 1.Cover 3 is slidingly matched between the two in having in described middle cover 2, and an end of cover 3 has an outward flange 31 in this, and the recessed edge 21 that cooperates with described outward flange 31 is arranged in the inboard of middle cover 2; Three uniform radially oil holes 12 and 22 are arranged on overcoat 1 and middle cover 2, an annular groove 13 and 23 along the circumference of overcoat 1 and middle cover is respectively arranged in their outer end, be beneficial to the diffusion of lubricant oil.
Claims (2)
1, the box-like sliding bearing of a kind of linner ball type three-layered node, comprise overcoat and middle cover, middle cover is positioned within the overcoat, be slidingly matched for sphere between the two, end in the overcoat inboard has the axial groove of inserting, and it is characterized in that: be with interior cover in described centre, be slidingly matched between the two, cover one end has an outward flange in this, and the recessed edge that cooperates with described outward flange is arranged in the middle cover inboard; Oil hole is radially arranged on overcoat and middle cover, have along the annular groove of overcoat and middle cover circumference in the outer end of this oil hole.
2, the box-like sliding bearing of linner ball type three-layered node according to claim 1 is characterized in that: described oil hole has three and be uniformly distributed along the circumference.
