Abstract
The utility model discloses an ultrahigh-molecular-weight polyethylene supporting-roller sealing piece. The ultrahigh-molecular-weight polyethylene supporting-roller sealing piece comprises a pipe body, a bearing, a shaft, a sealing bearing seat and an O-shaped ring, and is characterized in that the bearing is separately fixed on the shaft which is arranged in the sealing bearing seat; then the sealing bearing seat is arranged in the pipe body, is made of ultrahigh-molecular-weight polyethylene, is provided with a self-locking seam allowance and an O-shaped groove, and is closely matched with the pipe body by the self-locking seam allowance so as to form a self-locking form; and the O-shaped groove is provided with the O-shaped ring and is closely matched on the shaft so as to form a whole sealed body. The ultrahigh-molecular-weight polyethylene supporting-roller sealing piece has the beneficial effects that the structure is simple, and the installation is convenient; and the bearing seat, an oil seal and a pressing cover are integrated, so that the sealing effect is good, and further the service life of a supporting roller is prolonged by 2-3 times.
Description
Technical field
The utility model relates to a kind of superhigh molecular weight polyethylene idler Sealing.
Background technique
Present carrying roller mainly is made up of bearing support, oil sealing, gland three parts, and the main problem of idler structure is a sealing problem, and the life-span of carrying roller mainly is to be decided by the effect that seals; Because sealing effect is relatively poor; Cause the life-span of bearing to be reduced, whole carrying roller will be scrapped after the damage of bearings, can't continue to use; Increase cost of production, caused very big waste.
Summary of the invention:
The utility model provides a kind of superhigh molecular weight polyethylene idler Sealing in order to solve the problem that existing technology exists.
The technological scheme that the utility model adopted is: a kind of superhigh molecular weight polyethylene idler Sealing; Form by body, bearing, axle, sealed bearing, O type circle, it is characterized in that described bearing is fixed on separately on the axle, the axle sealed bearing of packing into of rigid bearing will be arranged; Again with the sealed bearing body of packing into; Described sealed bearing adopts superhigh molecular weight polyethylene material, and is provided with self-locking rim of the mouth and O type groove, closely cooperates and forms the form of self-locking through self-locking rim of the mouth and body; At O type groove O type circle is installed and is engaged in closely on the axle, form the integral body of a sealing.
The utility model beneficial effect: simple in structure, easy for installation, bearing support, oil sealing, gland are combined together, good sealing effect can make improve 2-3 doubly the working life of carrying roller.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Accompanying drawing is the utility model structural representation.
Among the figure: 1, body, 2, bearing, 3, axle, 4, the self-locking rim of the mouth, 5, sealed bearing, 6, O type circle.
Embodiment
As shown in the figure, a kind of superhigh molecular weight polyethylene idler Sealing is fixed on bearing 2 separately on the axle 3; Axle 3 sealed bearings 5 of packing into that rigid bearing 2 will be arranged, with sealed bearing 5 body 1 of packing into, sealed bearing 5 adopts superhigh molecular weight polyethylene materials again; Be provided with self-locking rim of the mouth 4 and O type groove; Closely cooperate and form the form of self-locking through self-locking rim of the mouth 4 and body 1, at O type groove O type circle 6 is installed and is engaged in closely on the axle 3, form the integral body of a sealing.
