Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As depicted in figs. 1 and 2, the utility model provides a kind of distortion-free oiliness bearing, including bearing body 1, institute
The top for stating bearing body 1 is provided with ring cowling circle 2, and 1 bottom of bearing body is provided with underseal ring 3, in the bearing body 1
Portion is set with interior envelope chamber column 4, and self-lubricating layer 5, and the interior envelope chamber column 4 are provided between the interior envelope chamber column 4 and bearing body 1
With the clamping ring ring 6 of 5 bottom of self-lubricating layer insertion hollow round table shape, wherein bearing body 1, ring cowling circle 2 and the one of underseal ring 3 at
Type, interior envelope chamber column 4, self-lubricating layer 5, clamping ring ring 6 are linked together with bearing body 1 by sintering processing, and self-lubricating layer 5 is passed through
