The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of oil mist lubrication that can substitute bearing is provided, simplifies the design of lubrication system of machinery and the high speed stuffing box bearing of manufacturing, the dustproof effect of raising and leakproof fat effect.
The technological scheme that provides according to the utility model, described high speed stuffing box bearing, it comprises inner ring body, outer ring body, ball and retainer, outer surface at inner ring body is provided with interior raceway, raceway outside the internal surface of outer ring body is provided with, interior raceway is combined to form complete ball road with outer raceway, in ball road, be provided with ball, outside ball, be provided with retainer, be provided with the first dustproof groove and second groove that prevents dust at the internal surface of the outer ring body of the ball left and right sides, be embedded with first dust ring at the first dustproof groove, be embedded with second dust ring at the second dustproof groove, be spaced a distance between the inwall of described first dust ring and the outer surface of inner ring body, be spaced a distance between the inwall of described second dust ring and the outer surface of inner ring body.
Interval 0.2 ~ 0.4mm between the inwall of described first dust ring and the outer surface of inner ring body, interval 0.2 ~ 0.4mm between the inwall of described second dust ring and the outer surface of inner ring body.
The race diameter of described first dust ring is greater than the race diameter of second dust ring, and the interior circular diameter of first dust ring is greater than the interior circular diameter of second dust ring.
Described first dust ring embeds outer shroud, first connecting ring and the first interior ring one by first and constitutes, and the inwall width of first dust ring is 1/2 of the first interior ring place, the first dust ring thickness; Described second dust ring embeds outer shroud, second connecting ring and the second interior ring one by second and constitutes, the inwall width of second dust ring is less than the thickness at its second interior ring place, and the first dust ring thickness at the first interior ring place is identical with the second dust ring thickness at ring place in second.
The outer surface of the inner ring body in interior raceway left side is a conical surface, and the conical tip of described conical surface correspondence is positioned at the left side of first dust ring.
The internal surface of the outer ring body on outer raceway right side is a conical surface, and the conical tip of described conical surface correspondence is positioned at the left side of first dust ring.
The present invention can substitute the oil mist lubrication of bearing in use, has simplified the design and the manufacturing of the lubrication system of machinery.Improve the dustproof effect and the leakproof fat effect of bearing.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure, this high speed stuffing box bearing, it comprises inner ring body 1, outer ring body 2, ball 3 and retainer 4, outer surface at inner ring body 1 is provided with interior raceway, raceway outside the internal surface of outer ring body 2 is provided with, interior raceway is combined to form complete ball road with outer raceway, in ball road, be provided with ball 3, ball 3 is made by stupalith, outside ball 3, be provided with retainer 4, be provided with the first dustproof groove and second groove that prevents dust at the internal surface of the outer ring body 2 of ball 3 left and right sides, be embedded with first dust ring 5 at the first dustproof groove, be embedded with second dust ring 6 at the second dustproof groove, be spaced a distance between the outer surface of the inwall of described first dust ring 5 and inner ring body 1, be spaced a distance between the outer surface of the inwall of described second dust ring 6 and inner ring body 1.
Interval 0.2 ~ 0.4mm between the outer surface of the inwall of described first dust ring 5 and inner ring body 1, interval 0.2 ~ 0.4mm between the outer surface of the inwall of described second dust ring 6 and inner ring body 1.
The race diameter of described first dust ring 5 is greater than the race diameter of second dust ring 6, and the interior circular diameter of first dust ring 5 is greater than the interior circular diameter of second dust ring 6.
