Abstract
The utility model belongs to the field of bearing technology and relates to a bidirectional thrust roller bearing, comprises a shaft ring, the base rings as well as a maintenance bracket, a maintenance cover, a roller, a middle circular spacer and bolts. The maintenance bracket is connected with the maintenance cover by bolts. A middle circular spacer is arranged between the two base rings. Inner spacers are arranged on either upper or lower part of the shaft ring to adjust the axial windage. The beneficial effects of low fabrication cost, the minimal width and minimal exterior diameter of the bearing in the case of the same bearing under the same axial load, the utility model is mainly applied to axial positioning of the mainframe adopted by industries including rolling mill, electrical machines and metallurgy.
Description
Affiliated technical field
The utility model belongs to technical field of bearings, relates to a kind of two-way biserial cylindrical roller thrust bearing, is mainly used in milling train, electromechanics, metallurgy industry, and main frame is carried out axially locating.
Background technique
At present, the needs that the user uses according to bearing, requirement can be born bi-directional axial power, and the bigger bearing of load, other types axially locating bearing at present, single, double angular contact ball bearing, biserial large cone angle roller bearing is bearing under the bigger situation of axial load, and bearing width broad bearing outside diameter is bigger, bearing manufacture cost height, Economy is reported to the leadship after accomplishing a task.
Summary of the invention
The utility model proposes a kind of this kind of bidirectional propulsion roller bearing bearing is separable bearing, with the single, double angular contact ball bearing of other types axially locating bearing, biserial large cone angle roller bearing etc. is compared, at the equal diameter of axle, bear under the situation of equal axial load, bearing width is the narrowest, the bearing outside diameter minimum.
The technical solution of the utility model is, a kind of bidirectional propulsion roller bearing, form by blowout patche 3, seat ring 6 and maintenance stand 7, retainer lid 4, roller 5, middle spacer ring 2 and screw 1, retainer lid 4 is connected by screw 1 with keeping stand 7, spacer ring 2 in being provided with between two seat rings 6 is respectively equipped with cone spacer 8 in the upper and lower of blowout patche 3.Spacer ring 2 in being provided with between two seat rings 6 works the axial internal clearance effect of adjusting.
The beneficial effects of the utility model are low cost of manufactures.At the equal diameter of axle, bear under the situation of equal axial load, bearing width is the narrowest, the bearing outside diameter minimum.
Description of drawings
Fig. 1 is a cylindrical roller thrust structure assembling schematic representation of the present utility model.
Among the figure, 1, screw, 2, middle spacer ring, 3, blowout patche, 4, the retainer lid, 5, roller, 6, seat ring, 7, keep stand, 8 cone spacers.
Embodiment
Retainer lid 4 is connected by screw 1 with keeping stand 7, and spacer ring 2 in being provided with between two seat rings 6 is respectively equipped with cone spacer 8 in the upper and lower of blowout patche 3.Except blowout patche 3, seat ring 6 and retainer, the external blowout patche 3 of roller assembly has increased by two cone spacers 8 up and down.Between two seat rings cage ring is arranged, work the axial internal clearance effect of adjusting.
