Abstract
The utility model relates to a joint bearing for an isolating switch. The joint bearing for the isolating switch comprises a pair of inner ring and outer ring, and a rod end body, wherein the matched surfaces of the inner ring and the outer ring are spherical and contact the surface in a sliding manner, the rod end body has a screw structure; a backstop for limiting the outer ring is arranged at one side of a mounting hole of the rod end body; a backstop tabling groove matched with the backstop of the rod end body is arranged at the end part of the outer ring; a covered edge for limiting the outer ring is arranged at the other side of the mounting hole of the rod end body; the covered edge is of an annular ring structure extending out of the side of the rod end body before being crimped together with the outer ring; the diameter of an inner hole of the annular ring is greater than that of the mounting hole; the covered edge is tightly attached to the outer ring after being crimped together with the outer ring; abrasion and scratch to an anticorrosion layer at the inner wall of the covered edge are not caused, so that the rod end body and two ends of the outer ring are sealed; the anticorrosion layers at two ends are not damaged; the rod end body can adopt a steel forging element or other high-strength material with an anti-corrosion coating when the antiseptic property of the joint bearing is ensured; and the situation that the rod end body does not easily crack on the basis of not affecting the antiseptic property is ensured.
Description
Technical field
The utility model relates to a kind of isolating switch joint shaft bearing, particularly the high isolating switch joint shaft bearing of a kind of not easy-rupturing and antiseptic property.
Background technique
Joint shaft bearing mainly is made up of spheroid and the lining by inner ball surface by outer spherical surface, can bear radial load, axial load or radially, axial simultaneous joint load, the oscillating motion that the speed that is widely used in is lower, banking motion and rotatablely move.
License ZL201020118071.9 discloses a kind of (a kind of spherical plain bearing rod end of isolating switch), it comprises the inside and outside circle with spherical sliding contact surface, and one be enclosed within the rod end body that has screw-rod structure on the outer ring, rod end body and outer ring interference fit, the screw-rod structure of rod end body is threaded with links such as pull bars.Traditional rod end body adopts stainless steel material to make, and its insufficient strength is at the place, narrow footpath of rod end body easy-rupturing; And when adopting similar structure such as 45 carbon constructional quality steel forging hot galvanizings, though easy-rupturing not because rod end body and outer ring interference fit, damages the zinc coat of rod end body internal layer easily, the reduction antiseptic property, working life is low.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of not easy-rupturing and the high isolating switch joint shaft bearing of antiseptic property.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of isolating switch joint shaft bearing, comprise that a pair of fitting surface is the inside and outside circle on spherical sliding contact surface, and the rod end body with screw-rod structure, drive the mounting hole with the outer ring interference fit on the described rod end body, its innovative point is: mounting hole one side of described rod end body arranges the spacing backstop of using in outer ring, and end, described outer ring arranges the backstop telescoping groove that cooperates with rod end body backstop; The mounting hole opposite side of rod end body arranges the spacing bound edge of using in outer ring, described bound edge with the outer ring crimping before be the annular ring structure of stretching out the rod end body side surface, and the diameter of bore of annular ring is greater than the mounting hole diameter; Described bound edge with the outer ring crimping after be close to the outer ring.
Further, described rod end body is surperficial steel forgings structure of establishing zinc coat.
Advantage of the present utility model is: during assembling, at first the outer ring is pressed into the mounting hole of rod end body, and makes the backstop on rod end body right side embed the backstop telescoping groove of this side of outer ring, thereby realize that the outer ring is in the spacing of this side of rod end body and sealing; Be pressed in the mounting hole process in the outer ring, bound edge is the annular ring structure, and the diameter of bore of annular ring is greater than the mounting hole diameter, makes to have a step surface between its inwall and the mounting hole inwall, can not cause wearing and tearing, the scuffing of bound edge inner wall anti-corrosive layer; Bound edge with the outer ring crimping after be close to the sealing that realizes this side, spacing with the outer ring.
Thereby make the two ends of rod end body and outer ring all obtain sealing, and this sealed at both ends place anticorrosive coat not damaged, when guaranteeing the joint shaft bearing antiseptic property, the rod end body can adopt steel forgings or other high strength band coating for protection against corrosion materials of band zinc coat, guarantees that the rod end body does not influence on the basis of antiseptic property not easy-rupturing.

Fig. 2 is the phase diagram of rod end body before installing with the outer ring in the utility model.
Fig. 3 is partial enlarged drawing I among Fig. 2.
Embodiment
As shown in Figure 1, 2, comprise rod end body 1, outer ring 2, inner ring 3, backstop, bound edge.
In the above-mentioned outer ring 2 inner ring 3 is set, both fitting surfaces are for having spherical sliding contact surface.
Comprise that also one has the rod end body 1 of screw-rod structure, drive the mounting hole with outer ring 2 interference fit on the rod end body 1, in a side of rod end body 1 the spacing backstop of using in outer ring is set, a side of outer ring 2 arranges the backstop telescoping groove, and rod end body 1 opposite side arranges the spacing bound edge of using in outer ring.Bound edge with outer ring 2 crimping before for stretching out the annular ring structure of rod end body 1 side, and the diameter of bore of this annular ring is greater than the mounting hole diameter, make between annular ring inwall and the mounting hole inwall to have a step surface, and bound edge with outer ring 2 crimping after be close to sealing with outer ring 2.In the utility model, the steel forgings structure that rod end body 1 is established zinc coat for the surface also can be the structure that the high-strength material of other surperficial coated anti-corrosion layers is made.
During assembling, at first outer ring 2 is pressed into the mounting hole of rod end body 1, and makes the backstop on rod end body 1 right side embed the backstop telescoping groove of outer ring 2 these sides, thereby realize that the outer ring is in the spacing of rod end body right side and sealing;
Be pressed in the mounting hole process in outer ring 2, as shown in Figure 3, bound edge is annular ring, has a step surface drop H between its inwall and the mounting hole inwall, can not cause wearing and tearing, the scuffing of bound edge inner wall anti-corrosive layer;
With bound edge and outer ring 2 crimping, make the inwall of bound edge be close to outer ring spacing, the sealing in formation left side, 2 surface again.
