Description
Technical field：
Technical field of bearings is the utility model is related to, more specifically to a kind of bearing with spherical outside surface usherd to seat.
Background technology：
Conventional bearing with spherical outside surface is to use dust cap by grease seal between the inner ring of bearing and outer ring, when bearing is transported
After row a period of time, because the greasy property of grease decreases, at this moment need to inject grease into bearing again, and work as ectosphere
After spherical bearing is fixed on bearing block, want to inject grease into bearing with regard to very inconvenient.
Utility model content：
The purpose of this utility model and provides a kind of precision and usherd to seat bearing with spherical outside surface aiming at the deficiency of prior art,
It is very square to change grease by setting oil groove to carry out replacing grease in situation about not pulling down by bearing with spherical outside surface on bearing block for it
Just, be advantageous to improve the service life of bearing with spherical outside surface.
Technology solution of the present utility model is as follows：
Precision is usherd to seat bearing with spherical outside surface, including bearing block, and bearing with spherical outside surface is made up of outer ring, inner ring, retainer and ball,
Ball is arranged on retainer, and retainer is clamped between outer ring and inner ring；
First dust cap and the second dust cap are fastened between outer ring and inner ring, and outer ring fuel feed hole, axle are formed on outer ring
Inlet nozzle is formed in bearing, being blocked on inlet nozzle has oil nozzle plug；Dome shape annular groove is molded on the center bore inner wall of bearing block, outside
Circle is placed in dome shape annular groove and is fixed together with bearing block；
Annular oil groove is formed on bearing block, inlet nozzle is connected to each other with annular oil groove, annular oil groove and outer ring fuel feed hole phase
Connect.
The cross section of first dust cap is L-type, and the right-hand member of the first dust cap is fastened in the neck of inner ring first, first
The left end of dust cap is fastened in the neck of outer ring first of triangle；The cross section of second dust cap is " one " font, and second is anti-
The right-hand member of dirt lid is fastened in the neck of inner ring second, and the left end of the second dust cap is fastened in the neck of outer ring second of arc；The
The left part of two dust caps is elastic rubbery body.
The beneficial effects of the utility model are：
It is more changed oil by setting oil groove to carry out replacing grease in situation about not pulling down by bearing with spherical outside surface on bearing block
Fat is very convenient, is advantageous to improve the service life of bearing with spherical outside surface.

Embodiment：
Embodiment：As shown in Fig. 1 to 3, precision is usherd to seat bearing with spherical outside surface, including bearing block 1, bearing with spherical outside surface by outer ring 2,
Inner ring 3, retainer 4 and ball 5 are formed, and ball 5 is arranged on retainer 4, and retainer 4 is clamped between outer ring 2 and inner ring 3；
First dust cap 6 and the second dust cap 7 are fastened between outer ring 2 and inner ring 3, and outer ring oil-feed is formed on outer ring 2
Hole 21, inlet nozzle 12 is formed on bearing block 1, on inlet nozzle 12 closure have oil nozzle plug 8；On the center bore inner wall of bearing block 1 into
Type dome shape annular groove 11, outer ring 2 are placed in dome shape annular groove 1 and are fixed together with bearing block 1；
Annular oil groove 13 is formed on bearing block 1, inlet nozzle 12 is connected to each other with annular oil groove 13, annular oil groove 13 and outer ring
Fuel feed hole 21 is connected to each other.
The cross section of first dust cap 6 is L-type, and the right-hand member of the first dust cap 6 is fastened in the first neck of inner ring 31,
The left end of first dust cap 6 is fastened in the first neck of outer ring 22 of triangle；The cross section of second dust cap 7 is " one " word
Type, the right-hand member of the second dust cap 7 are fastened in the second neck of inner ring 32, and the left end of the second dust cap 7 is fastened on the outer ring of arc
In second neck 23；The left part 71 of second dust cap 7 is elastic rubbery body.
Operation principle：Pass through the first dust cap 6 and the double-layer seal of the second dust cap 7, spherical outside surface between outer ring 2 and inner ring 3
The good seal performance of bearing.
During grease injection, oil nozzle plug 8 is opened, grease is injected into inlet nozzle 12, grease can enter annular oil groove 13, Ran Houzai
Enter the inside of bearing with spherical outside surface by outer ring fuel feed hole 21, bearing with spherical outside surface need not be pulled down by reaching, can also be to spherical outside surface
Bearing carries out the effect of grease injection.
