Abstract
The invention relates to a self-lubricating bearing. The self-lubricating bearing comprises a bearing inner frame, a bearing outer frame and spherical rollers. The rollers are arranged between the inner frame and the outer frame. The two transverse sides of each roller are each provided with a spherical supporting piece. A sliding groove is formed in the middle of each supporting piece. An auxiliary sliding groove is formed in the middle of the inner wall of the bearing outer frame and the middle of the inner wall of the bearing inner frame. An auxiliary roller is further arranged between every two adjacent supporting pieces. The auxiliary rollers are columnar. An annular protruding part which is embedded in the corresponding sliding groove and the auxiliary sliding groove is arranged in the middle of each auxiliary roller. According to the structure of the self-lubricating bearing, a hard shell is arranged on the bearing rollers and supported through the auxiliary rollers, the shell has certain deformation, and thus abrasion and impact of the bearing outer frame and the bearing inner frame can be reduced.
Description
Technical field
The present invention relates to a kind of self-lubricating bearing, belong to field of bearings.
Background technique
Traditional bearing adopts simple housing, inside casing adds roller and forms, roller directly and housing, inside casing friction realize the rotation of bearing, because the narrow limitation of roller shape and material, be difficult to avoid roller to the wearing and tearing of housing and inside casing, simultaneously in a lot of equipment, bearing also bears the uncertain impact of larger radial direction, and roller is easy to produce pit on bearing inside casing, housing, affects bearing performance.
Summary of the invention
The technical problem to be solved in the present invention is: the problem overcoming bearing durability difference of the prior art, provides a kind of bearing of durable, good stability.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of self-lubricating bearing, comprise bearing inside casing, housing and spherical roller, described roller is arranged between inside casing and housing, described roller comprises a spherical shell, circular opening is symmetrically arranged with at the radial two ends of described shell, support block is filled with in described spherical housing, described support block adopts porous material to make, the corresponding circular open of described support block be provided with a hemispheric embedding groove, in described embedding groove, be inlaid with ball, described bearing inside casing and housing are provided with the slot rolling corresponding with described ball.
As further innovation of the present invention, described porous material is pottery.
As further innovation of the present invention, described shell adopts Elastic Steel to make.
The invention has the beneficial effects as follows:
This structure is led to and is improved traditional bearing roller, reduces the weight of conventional roller, and porous material can adsorb more lubricant oil simultaneously, smoothness good when ball ensures to contact with bearing inside casing, housing.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structure of the present invention.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1, the present invention is a kind of self-lubricating bearing, comprise bearing inside casing 2, housing 1 and spherical roller, described roller is arranged between inside casing 2 and housing 1, described roller comprises a spherical shell 5, circular opening is symmetrically arranged with at the radial two ends of described shell 5, support block 3 is filled with in described spherical housing 5, described support block 3 adopts porous material to make, the corresponding circular open of described support block 3 be provided with a hemispheric embedding groove, ball 4 is inlaid with in described embedding groove, described bearing inside casing 2 and housing 1 are provided with the slot rolling corresponding with described ball 4,
Described porous material is pottery;
Described shell 5 adopts Elastic Steel to make.
When bearing normally works, porous material lubricates ball 4, and ensure bearing good working order, when bearing is hit, porous material can carry out energy-absorbing to bearing, and hemispheric embedding groove surface of contact is larger simultaneously, is not easy to bring wearing and tearing to ball 4.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
