Abstract

The utility model discloses a double-row double-outer-ring roller bearing. The double-row double-outer-ring roller bearing comprises outer bearing rings, an inner bearing ring, multiple rollers and a lining ring, wherein the outer bearing rings are provided with roller rabbets, and the inner bearing ring is provided with two roller grooves; and the two outer bearing rings are respectively sleeved on the inner bearing ring, the multiple rollers are distributed among the roller grooves of the inner bearing ring and inner holes of the outer bearing rings, and the lining ring is arranged between the two outer bearing rings. The double-row double-outer-ring roller bearing provided by the utility model comprises the symmetrical double outer bearing rings and the inner bearing ring, which are matched with each other, and has the advantages of simple structure, high carrying capacity, small occupation space and high assembly accuracy.

Description

The two outer rings of a kind of biserial roller bearing

Technical field

The utility model relates to the mechanical bearing technical field, especially a kind of biserial pair outer rings roller bearing.

Background technique

In prior art, for improving the bearing capacity of machinery, increase the service life, in particular for oil, mine, control in the heavy machinery of golden industry, its spindle end adopts double sets of bearings to be set up in parallel, namely two cover bearings combine use, the problem that this structure exists is, it is large that bearing support takies the spatial position of casing, two cover bearing assemble difficulties, the error accumulation of two cover bearings self causes mechanical precision to reduce between main shaft and bearing support, noise increases, and can't satisfy the user to the user demand of heavy machinery.

The model utility content

The purpose of this utility model is a kind of biserial pair outer rings roller bearing that provides for the deficiencies in the prior art, the utility model adopts symmetrically arranged duplex bearing outer ring and the supporting double-row roller bearing that forms of bearing inner race, have advantages of simple in structure, bearing capacity greatly, take up room little, assembly precision is high.

The concrete technological scheme that realizes the utility model purpose is:

The two outer rings of a kind of biserial roller bearing, its characteristics comprise bearing outer ring, bearing inner race, roller and lining ring, on described bearing outer ring, a side of endoporus is provided with the roller seam, is provided with side by side twice roller groove on the bearing inner race external diameter; Described bearing outer ring is two, and its side symmetry that is provided with the roller seam arranges outwardly, and is set on bearing inner race, and roller is several, is distributed between the endoporus of the roller groove of bearing inner race and bearing outer ring, and lining ring is located between two bearing outer rings.

The utility model adopts symmetrically arranged duplex bearing outer ring and the supporting double-row roller bearing that forms of bearing inner race, have advantages of simple in structure, bearing capacity greatly, take up room little, assembly precision is high.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

Consult Fig. 1, the utility model comprises bearing outer ring 1, bearing inner race 2, roller 3 and lining ring 4, and on described bearing outer ring 1, a side of endoporus is provided with roller seam 11, is provided with side by side twice roller groove 21 on bearing inner race 2 external diameters; Described bearing outer ring 1 is two, its side symmetry that is provided with roller seam 11 arranges outwardly, and is set on bearing inner race 2, and roller 3 is several, be distributed between the endoporus of the roller groove 21 of bearing inner race 2 and bearing outer ring 1, lining ring 4 is located between two bearing outer rings 1.

The utility model is to use like this:

During the utility model assembling, at first, main shaft is placed in the bearing support of casing, one end of main shaft is installed, and a bearing outer ring 1 that will be positioned at box inside is press fitted into the bearing support of casing, puts bearing inner race 2 and roller 3 at an end of main shaft, bearing inner race 2 is pressed in main shaft, and roller 3 and the roller seam 11 of bearing outer ring 1 are touched, the lining ring 4 of packing in bearing support is press-fitted another part bearing outer ring 1 at last in the bearing support of casing; Repeat said process the other end of main shaft is installed, adjust the axial clearance of main shaft and bearing, bearing cap is installed on casing, assemble complete.

The utility model adopts symmetrically arranged duplex bearing outer ring and the supporting double-row roller bearing that forms of bearing inner race, its bearing outer ring 1, bearing inner race 2 and roller 3 are the supporting setting of dispatching from the factory, the precision of himself is much larger than the two cover bearings that combine use, and the space that takies housing bearing seat is little, is the design of heavy machinery and the manufacturing condition of providing convenience.
