Abstract
The invention relates to a self-lubricating knuckle bearing. The self-lubricating knuckle bearing is characterized by comprising an outer ring, an inner ring, a rolling needle, a self-lubricating gasket and a middle ring, wherein the inner ring is arranged in the outer ring; the middle ring is arranged between the inner ring and the outer ring; the rolling needle is arranged between the middle ring and the inner ring; and the self-lubricating gasket is arranged between the middle ring and the outer ring, so that the combined knuckle bearing formed by combining the self-lubricating knuckle bearing and a rolling needle bearing is formed. The self-lubricating knuckle bearing is formed by combined use of the self-lubricating knuckle bearing and the rolling needle bearing, the functions of the two bearings are combined, so that not only are the functions of centering, bearing heavy loads and being free of maintenance of the self-lubricating knuckle bearing achieved, but also the function of flexible rotation of the rolling needle bearing can be realized. The self-lubricating knuckle bearing is simple in structure and convenient to use.
Description
Technical field
The present invention relates to a kind of self-lubricating knuckle bearing.
Background technique
Joint shaft bearing is a kind of sliding bearing of special construction.Its structural rate rolling bearing is simple, it is mainly made up of the outer ring of inner ball surface the inner ring of outer spherical surface and one by one, larger load can be born, the type different according to it and structure, radial load, axial load or radial direction, axially simultaneous joint load can be born.Joint shaft bearing is generally used for the lower oscillating motion of speed (i.e. angular motion), because slidingsurface is spheric, also can make banking motion (i.e. aligning motion) within the scope of several angle, supporting axle and axle housing hole nonconcentricity larger time, still can normally work.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technological scheme of self-lubricating knuckle bearing.
Described a kind of self-lubricating knuckle bearing, it is characterized in that comprising outer ring, inner ring, needle roller, selflubricating liner and centre circle composition, inner ring is provided with in described outer ring, centre circle is provided with between described inner ring and described inner ring, needle roller is provided with between described centre circle and described inner ring, be provided with selflubricating liner between described centre circle and described outer ring, thus form the combination joint shaft bearing combined by self-lubricating knuckle bearing and needle bearing.
Described a kind of self-lubricating knuckle bearing, it is characterized in that described centre circle internal diameter is the outer raceway of described needle bearing, described centre circle external diameter is the interior raceway of described self-lubricating knuckle bearing.
Described a kind of self-lubricating knuckle bearing, is characterized in that the radial clearance of described joint shaft bearing is: 0.02-0.035 μm.
Compared with prior art, the present invention is combinationally used by self-lubricating knuckle bearing and needle bearing and forms, combine the function of two kinds of bearings, the aligning of existing self-lubricating knuckle bearing, bear heavy duty, non-maintaining function, the function of needle bearing flexible rotating can be realized again.Structure of the present invention is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with Figure of description, the present invention will be further described:
As shown in Figure 1, the present embodiment provides a kind of combination joint shaft bearing, combinationally used by self-lubricating knuckle bearing and needle bearing and form, comprise outer ring 1, inner ring 2, needle roller 3, selflubricating liner 4 and centre circle 5 form, inner ring 2 is provided with in described outer ring 1, centre circle 5 is provided with between described inner ring 2 and described outer ring 1, be provided with needle roller 3 between described centre circle 5 and described inner ring 2, between described centre circle 5 and described outer ring 1, be provided with selflubricating liner 4, thus form the combination joint shaft bearing combined by self-lubricating knuckle bearing and needle bearing.
In the present embodiment, described centre circle 5 internal diameter is the outer raceway of needle bearing, and needle roller is arranged on centre circle 5 inner edge along in raceway; Described centre circle 5 external diameter is the interior raceway of joint shaft bearing, and centre circle 5 outer spherical surface and outer ring 1 inner ball surface are mutually coincide and can be rotated.
In the present embodiment, described needle roller 3 adopts without retainer design, significantly can strengthen the bearing capacity of needle roller 3, reduces the carrying difference with joint shaft bearing part, improves the overall work life-span of combination bearing.
In the present embodiment, described selflubricating liner 4 is close in the inner ball surface of described outer ring 1.
In the present embodiment, described outer ring 2 adopts PH Stainless Steel 0Cr17Ni4Cu4Nb to make.Inner ring 1, centre circle 5, needle roller 3 all adopt Martensitic Stain Less Steel 9Cr18 to make.The use of high-performance stainless steel material also improves the combination property of combination bearing.
In the present embodiment, in described combination joint shaft bearing, the radial clearance of bearing is: 0.02-0.035 μm.
After measured, the specific performance index of the present embodiment bearing is as follows:
1) under radial load 30kN condition, the set deformation volume of combination bearing is not more than 0.076mm;
2) adaptation of bearing is not more than 0.076mm;
3) under the swing wear test condition of radial 26kN, the wear extent of combination bearing is not more than 0.11mm;
4) soak through low temperature grease, under the swing wear test condition of radial 26kN, the wear extent of combination bearing is not more than 0.15mm.
From above-described embodiment, the present invention is combinationally used by self-lubricating knuckle bearing and needle bearing and forms, combine the function of two kinds of bearings, the aligning of existing self-lubricating knuckle bearing, bear heavy duty, non-maintaining function, the function of needle bearing flexible rotating can be realized again.Structure of the present invention is simple, easy to use.
