Abstract
The utility model provides a double-row cylindrical full-roller self-locking bearing, which includes an outer ring, an inner ring and two rows of cylindrical rollers, wherein the outer circumference surface of the outer ring is cylindrical, two rows of roller paths are arranged on the inner circumference surface of the outer ring and the outer circumference surface of the inner ring, and two rows of cylindrical rollers are arranged in the two rows of roller paths. The double-row cylindrical full-roller self-locking bearing is characterized in that two axial snap ring grooves are arranged on the outer circumference surface of the outer ring, and are placed on two axial sides of the outer ring respectively, and two seal grooves are arranged on the inner circumference surface of the outer ring, and are placed outside the roller paths; and two dust covers are arranged on the outer circumference surface of the inner ring, and are mounted in the seal grooves of the outer ring through snap rings. According to the utility model, the bearing can be axially positioned through mounting the snap rings in a pressed manner, so that the self-locking function of the bearing is achieved. At the same time, external dust can be effectively prevented from entering the interior of the bearing, so that the service life of the bearing is prolonged.
Description
Technical field
The utility model belongs to field of bearings, is specifically related to the full roller self-locking bearing of a kind of biserial cylinder.
Background technique
Existing biserial cylinder full type roller bearing is not because need the retainer guiding, and roller quantity is many, has strengthened the bearing capacity of bearing, is widely applied in the occasion with severe duty requirement.But the smooth often periphery of outer ring excircle of this class bearing can not be realized axially locating.Dust in the while bearing Environmental Conditions gets into bearing inside easily and pollutes, and causes that premature wear lost efficacy, and working life is low.
Summary of the invention
The utility model provides a kind of full roller self-locking bearing of biserial cylinder with axially locating function to the deficiency of above-mentioned existing technology.
The utility model is realized through following technological scheme:
The full roller self-locking bearing of a kind of biserial cylinder; Comprise outer ring, inner ring and two line column rollers, the outer peripheral surface of outer ring is cylindric, and the inner peripheral surface of outer ring and the outer peripheral surface of inner ring are provided with two row roller raceways; Two line column rollers are arranged in the two row roller raceways; It is characterized in that said outer ring outer peripheral surface is provided with two axial retention grooves, two axial retention grooves lay respectively at the axial both sides of outer ring.
Further, the inner peripheral surface of said outer ring is provided with two seal grooves, and said seal groove is positioned at the outside of roller raceway;
The outer peripheral surface of said inner ring is provided with two dust covers, and said dust cover is installed in the seal groove of outer ring through snap ring.
The utility model outer ring outer peripheral surface is provided with two axial retention grooves, during use, can realize the axially locating of bearing through press-fiting stop ring, thereby realize the auto-lock function of bearing.Simultaneously, the utility model is offered two seal grooves on the inner peripheral surface of outer ring, and press-fits through dust cover, and it is inner effectively to have avoided outside dust to get into bearing, has prolonged the working life of bearing.
Description of drawings
Fig. 1 is the full roller self-locking bearing sectional drawing of the described biserial cylinder of the utility model;
Fig. 2 is the sectional drawing of the described outer ring of the utility model;
Fig. 3 is the partial enlarged drawing of seal groove among Fig. 2.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Shown in Fig. 1-3; The utility model provides a kind of biserial cylinder full roller self-locking bearing; Comprise outer ring 1, inner ring 2 and two line column rollers 3; The outer peripheral surface of outer ring 1 is cylindric, and the outer peripheral surface of the inner peripheral surface of outer ring 1 and inner ring 2 is provided with two row roller raceways, and two line column rollers 3 are arranged in the two row roller raceways; The edge of roller raceway all offers arc groove.Said outer ring 1 outer peripheral surface is provided with the axial both sides that 6, two axial retention grooves 6 of two axial retention grooves lay respectively at outer ring 1.When bearing uses, can realize axially locating through press-fiting stop ring.
For fear of outside dust entering bearing inside, prolong the working life of bearing, the inner peripheral surface of the utility model outer ring 1 is provided with two seal grooves 7, and seal groove 7 is positioned at the outside of roller raceway, near the edge of outer ring 1.The outer peripheral surface of inner ring 2 is provided with two dust covers 4, and dust cover 4 is installed in the seal groove 7 of outer ring 1 through snap ring 5.
The utility model not only is confined to above-mentioned embodiment; Persons skilled in the art are according to the disclosed content of the utility model; Can adopt other multiple embodiment to implement the utility model, therefore, project organization of every employing the utility model and thinking; Do some simple designs that change or change, all fall into the scope of the utility model protection.
