Abstract
The utility model relates to technical field of bearings, specifically, relates to a kind of pinch roller assembly self-contained bearing.Described pinch roller assembly self-contained bearing is combined by two covers 33120 single-row circle dimension bearing, and described 33120 single row conical bearings comprise bearing outer ring, bearing inner race, bearing roller and retainer; Described bearing outer ring is positioned at the skin of bearing, and described bearing inner race is positioned at the internal layer of bearing, and described bearing roller is between bearing outer ring and bearing inner race, and described retainer is between bearing outer ring and bearing inner race and be wrapped in bearing roller; The pad of outer field spacer ring and internal layer is provided with between described two cover 33120 single row conical bearings.Two cover 33120 single row conical bearings of the present utility model are balanced to power, and can bear axial impact force and radial impact power simultaneously, thus substantially increase the working life of composite bearing, working life can reach 25-45 days.
Description
Technical field
The utility model relates to technical field of bearings, specifically, relates to a kind of pinch roller assembly self-contained bearing.
Background technique
In prior art, pinch roller assembly self-contained bearing is that 23120 bearings are installed in a superimposed manner.。The defect of this bearing stacked system is, because 23120 bearings are selfaligning roller bearing, in running, easily occur rolling element in rotating under axis and the erratic impact of radial direction, discontinuity, serious wear, working life is short, is only as 8-20 days.
Model utility content
The purpose of this utility model is, provides a kind of pinch roller assembly self-contained bearing, to solve the problems of the technologies described above.
For solving the problem, the technological scheme that the utility model adopts is:
A kind of pinch roller assembly self-contained bearing, is characterized in that: described pinch roller assembly self-contained bearing is combined by two covers 33120 single-row circle dimension bearing, and described 33120 single row conical bearings comprise bearing outer ring, bearing inner race, bearing roller and retainer; Described bearing outer ring is positioned at the skin of bearing, and described bearing inner race is positioned at the internal layer of bearing, and described bearing roller is between bearing outer ring and bearing inner race, and described retainer is between bearing outer ring and bearing inner race and be wrapped in bearing roller; The pad of outer field spacer ring and internal layer is provided with between described two cover 33120 single row conical bearings.
Beneficial effect: compared with prior art, two cover 33120 single row conical bearings of the present utility model are balanced to power, and can bear axial impact force and radial impact power simultaneously, thus substantially increase the working life of composite bearing, working life can reach 25-45 days.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, pinch roller assembly self-contained bearing described in the utility model is combined by two covers 33120 single-row circle dimension bearing.Described 33120 single row conical bearings comprise bearing outer ring 1, bearing inner race 4, bearing roller 2 and retainer 3; Described bearing outer ring 1 is positioned at the skin of bearing, described bearing inner race 4 is positioned at the internal layer of bearing, described bearing roller 2 is between bearing outer ring 1 and bearing inner race 4, and described retainer 3 is between bearing outer ring 1 and bearing inner race 4 and be wrapped in bearing roller 2.The pad 6 of outer field spacer ring 5 and internal layer is provided with between described two cover 33120 single row conical bearings.
