Abstract
The invention relates to a combined roller bearing. The combined roller 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. Each roller is sleeved with a supporting ring. The two radial ends of each roller are exposed from the two sides of the corresponding supporting ring and make contact with the bearing inner frame and the bearing outer frame. A plurality of supporting strips are arranged on the inner wall of each supporting ring in an annular array mode. The symmetry axis of each supporting strip is coaxial with the axis of the corresponding supporting ring. The supporting strips are in surface contact with the rollers. The supporting strips and the supporting rings are of an integral structure. The supporting rings are fixedly connected through elastic connecting ribs. A groove is machined in each connecting rib. Auxiliary rollers making contact with the bearing outer frame are embedded in the grooves.
Description
Technical field
The present invention relates to a kind of compound roller 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 compound roller bearing, comprise bearing inside casing, housing and spherical roller, described roller is arranged between inside casing and housing, a support ring is connected in the outer cover of described roller, the radial two ends of described roller are exposed from the both sides of support ring and contact with housing with bearing inside casing, on inwall in described support ring, annular arranged in arrays has some supporting bars, the axis of symmetry of described supporting bar and the axis coaxle of support ring, described supporting bar contacts with roller face, supporting bar and support ring are structure as a whole, be fixedly connected with by flexible connecting tendon between described support ring, described connecting tendon is also processed with a groove, the auxiliary roller contacted with bearing housing is inlaid with in described groove.
As further innovation of the present invention, described support ring adopts elastic steel sheet to make.
As further innovation of the present invention, described support ring is 60 to percent 90 percent to the coverage scale of roller.
The invention has the beneficial effects as follows:
This structure by being socketed in, bearing roller is arranged the shell of hard, to improve durability and the intensity of roller, can adsorpting lubrication oil in support adhesive member, and improve the maintenance period of bearing.
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 reinforcing roller 3 bearing, comprise bearing inside casing 2, housing 1 and spherical roller 3, described roller 3 is arranged between inside casing 2 and housing 1, a support ring 4 is connected in the outer cover of described roller 3, the radial two ends of described roller 3 are exposed from the both sides of support ring 4 and contact with housing 1 with bearing inside casing 2, on inwall in described support ring 4, annular arranged in arrays has some supporting bars 6, the axis of symmetry of described supporting bar 6 and the axis coaxle of support ring 4, described supporting bar 6 contacts with 3, roller, supporting bar 6 and support ring 4 are structure as a whole, be fixedly connected with by flexible connecting tendon 5 between described support ring 4, described connecting tendon 5 is also processed with a groove, the auxiliary roller 7 contacted with bearing housing 1 is inlaid with in described groove,
Described support ring 4 adopts elastic steel sheet to make;
The coverage scale of described support ring 4 pairs of rollers 3 is 60 to percent 90 percent.
The present invention is socketed support ring 4 on traditional bearing roller 3, and while not affecting bearing rotation, support ring 4 can carry out banding to roller 3, prevents roller 3 compressive deformation, even breaks.
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.
