Abstract
Long-life two-row ball bearing, axle is fixed on inner ring, upper dust cap is fastened between the aperture surface of outer ring and the outer diameter face of inner ring, lower dust cap is metal cap, the neck that cross section is triangle is formed on the aperture surface of outer ring, flexible rib is molded on the edge of lower dust cap, elastic rib is fastened in the neck that cross section is triangle；Cross through hole is formed on inner ring, collar groove is formed on axle, collar groove is relative with cross through hole, and the lower end of axle is located at the top of lower dust cap, and grease is marked with the sealing space that upper dust cap, lower dust cap, inner ring, outer ring and axle are formed.Its grease can fully flow between inner ring, outer ring and axle, can so extend the service life of two-row ball bearing, easy for installation with dust cap at present, good seal performance.
Description
Technical field：
Technical field of bearings is the utility model is related to, more specifically to a kind of two-row ball bearing of tape spool.
Background technology：
Existing tape spool two-row ball bearing, after axle is fixed on two-row ball bearing, axle cannot get grease with bearing close place
Lubrication, can so reduce the service life of two-row ball bearing.
Also a kind of situation is that the grease in bearing is sealed in bearing, and what grease contact with axle without, so
Result be that bearing is lubricated, and axle cannot lubricate, and so can also reduce the service life of tape spool two-row ball bearing.
Utility model content：
The purpose of this utility model and provides a kind of long-life two-row ball bearing aiming at the deficiency of prior art, it
Grease can fully flow between inner ring, outer ring and axle, can so extend the service life of two-row ball bearing, same to prevent at present
Dirt lid is easy for installation, good seal performance.
Technology solution of the present utility model is as follows：
Long-life two-row ball bearing, including outer ring, inner ring, retainer and ball, ball are arranged on retainer, retainer
It is clamped between outer ring and inner ring；Axle is fixed on inner ring, and upper dust cap is fastened on the aperture surface of outer ring and the outer diameter face of inner ring
Between, lower dust cap is metal cap, and the neck that cross section is triangle, the side of lower dust cap are formed on the aperture surface of outer ring
Flexible rib is molded on edge, elastic rib is fastened in the neck that cross section is triangle；
Cross through hole is formed on inner ring, collar groove is formed on axle, collar groove is relative with cross through hole, the lower end position of axle
In the top of lower dust cap, grease is marked with the sealing space that upper dust cap, lower dust cap, inner ring, outer ring and axle are formed.
The retainer has two, and two retainers are clamped between outer ring and inner ring.
The beneficial effects of the utility model are：
Its grease can fully flow between inner ring, outer ring and axle, and can so extend two-row ball bearing uses the longevity
Life, good seal performance easy for installation with dust cap at present.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
In figure：1st, outer ring；11st, neck；2nd, inner ring；21st, cross through hole；3rd, retainer；4th, ball；5th, upper dust cap；6、
Lower dust cap；61st, elastic rib；7th, axle；71st, collar groove.
Embodiment：
Embodiment：As shown in Figure 1, long-life two-row ball bearing, including outer ring 1, inner ring 2, retainer 3 and ball 4, ball
4 are arranged on retainer 3, and retainer 3 is clamped between outer ring 1 and inner ring 2；Axle 7 is fixed on inner ring 2, the upper blocking of dust cap 5
Between the aperture surface of outer ring 1 and the outer diameter face of inner ring 2, lower dust cap 6 is metal cap, is formed on the aperture surface of outer ring 1
Cross section is the neck 11 of triangle, is molded flexible rib 61 on the edge of lower dust cap 6, elastic rib 61 is fastened on transversal
Face is in the neck 11 of triangle；
Cross through hole 21 is formed on inner ring 2, collar groove 71 is formed on axle 7, collar groove 71 is relative with cross through hole 21,
The lower end of axle 7 is located at the top of lower dust cap 6, and the sealing that upper dust cap 5, lower dust cap 6, inner ring 2, outer ring 1 and axle 7 are formed is empty
Between in be marked with grease.
The retainer 3 has two, and two retainers 3 are clamped between outer ring 1 and inner ring 2.
Operation principle：In the course of work, grease can enter in collar groove 71 from cross through hole 21, allow grease inner ring 2,
Fully flowed between outer ring 1, axle 7, so preferably lubricate the utility model, so as to extend the service life of two-row ball bearing.
Lower dust cap 6 uses elastic rib 61 to be fastened on cross section as in the neck 11 of triangle, when good seal performance,
Second, install also very convenient, it is only necessary to which lower dust cap is firmly pressed on outer ring 1 and can installed.
