Abstract
The utility model discloses a novel spherical joint bearing. The novel spherical joint bearing is characterized by comprising a steel outer ring (1). A zinc-aluminium alloy inner ball (2) which is matched with the steel outer ring (1) in shape is arranged on the inner side of the steel outer ring (1), and a plurality of solid self-lubricating columns (3) are evenly embedded on the surface of the zinc-aluminium alloy inner ball (2). The zinc-aluminium alloy inner ball (2) comprises the following components by mass ratio of zinc: aluminium: copper=28-33: 10-14: 1. Under the premise that the performance is not affected, the novel spherical joint bearing can lower material cost.
Description
Technical field
The utility model relates to a kind of joint shaft bearing, particularly a kind of new spherical joint shaft bearing that can significantly reduce costs and not affect performance.
Background technique
The outer ring that use on the water conservancy project arc-shaped door, that traditional spherical joint bearing comprises a steel, be provided with endosphere with this outer ring matches, this endosphere adopts Cuprum alloy to make, surface inserting at endosphere is provided with a plurality of solid-state selflubricating posts, when endosphere and outer ring relatively rotate, the selflubricating post can form a self-lubricating layer on surface of contact both, guarantee carrying out smoothly of rotation.But the existing shortcoming of the joint shaft bearing of this conventional construction is, adopts the copper alloy made endosphere, and is with high costs, increased construction cost and economic burden.Therefore need now a kind of new spherical joint shaft bearing that can address the above problem.
Summary of the invention
The utility model is in order to solve the existing above-mentioned deficiency of prior art, to propose significantly to reduce the new spherical joint shaft bearing of cost of material under a kind of prerequisite not affecting performance.
Technical solution of the present utility model is: a kind of new spherical joint shaft bearing, it is characterized in that: described joint shaft bearing comprises steel outer ring 1,1 inboard is provided with the allumen endosphere 2 that shape matches with it in the steel outer ring, is inlaid with equably a plurality of self-lubricating solid posts 3 on the surface of allumen endosphere 2.
The composition of described allumen endosphere 2 and mass ratio are:
Zinc: aluminium: copper=28-33:10-14:1.
The utility model is compared with prior art, has following advantage:
the spherical joint bearing of this kind of structural type, it is simple in structure, design ingenious, rationally distributed, it adopts copper alloy made for traditional spherical joint bearing endosphere, cause holistic cost high, the practical problem that construction cost and economic burden are heavier, utilize the allumen endosphere to come the endosphere of instead of copper alloy, the performance of the performance of this allumen endosphere and Cuprum alloy endosphere is very nearly the same, but cost is only 2/3rds of Cuprum alloy endosphere, therefore this spherical joint bearing can satisfy under the prerequisite of technological requirement, significantly save cost, its market prospects are very wide.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: a kind of new spherical joint shaft bearing, this joint shaft bearing comprises a steel outer ring 1,1 inboard is provided with the allumen endosphere 2 that shape matches with it in the steel outer ring, and also is inlaid with equably a plurality of self-lubricating solid posts 3 on the outer surface of allumen endosphere 2; The composition of this allumen endosphere 2 and mass ratio are:
Zinc: aluminium: copper=28-33:10-14:1.
The utility model embodiment's new spherical joint shaft bearing is when work, steel outer ring 1 and allumen endosphere 2 relatively rotate, the self-lubricating solid post 3 that is embedded in allumen endosphere 2 surfaces can form a lubricating layer at surface of contact place both, guarantees the smooth and easy of relative movement.The performance of the properties of the allumen endosphere 2 that the special proportioning of this employing is made and traditional Cuprum alloy endosphere is very nearly the same, but cost is only 2/3rds of Cuprum alloy endosphere, can effectively control cost.
Claims (1)
1. new spherical joint shaft bearing, it is characterized in that: described joint shaft bearing comprises steel outer ring (1), be provided with the allumen endosphere (2) that shape matches with it in the inboard of steel outer ring (1), be inlaid with equably a plurality of self-lubricating solid posts (3) on the surface of allumen endosphere (2).
