Abstract
The invention discloses a dual-seal miniature bearing which comprises an inner ring, an outer ring and balls arranged between the inner ring and the outer ring. The dual-seal miniature bearing is characterized in that a first dustproof structure is arranged on one side of the balls and comprises a first dustproof cover arranged on the inner circumferential face of the outer ring and a second dustproof cover arranged on the outer circumferential face of the inner ring. According to the dual-seal miniature bearing, the first dustproof structure is arranged on the side, in contact with the external environment, of the bearing and comprises the first dustproof cover and the second dustproof cover, and a seal part for dust prevention is added on the basis of an original seal part for dust prevention; moreover, the first dustproof cover and the second dustproof cover are fixed to the inner ring and the outer ring respectively, when the inner ring and the outer ring relatively rotate, the first dustproof cover and the second dustproof cover also rotate, so that steady air flow is formed between the two dustproof covers, dust is prevented from entering the bearing, and the dustproof effect is greatly improved.
Description
Technical field
The present invention relates to a kind of ball bearing, specifically a kind of double seal miniature bearing with dust cover.
Background technique
Ball bearing structure is made up of inner ring, outer ring and the ball that is placed in inner ring and outer ring.When bearing at bad environments use, such as flowmeter etc., just having dust and enters Bearing inner, cause the flexibility of bearing to decline, in order to not affect the transmission performance of bearing, needing to carry out dustproof design to bearing, thus improve the working life of bearing.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned the deficiencies in the prior art, and provides a kind of double seal miniature bearing preventing dust from entering the good dustproof effect of Bearing inner.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Double seal miniature bearing, comprise inner ring, outer ring and be placed in the ball of inner ring and outer ring, it is characterized in that: the side of described ball is provided with the first dustproof construction, this first dustproof construction comprises the first dust cover being arranged on described outer ring inner peripheral surface and the second dust cover being arranged on described inner ring outer circumferential face.
Between described inner ring and outer ring, be also provided with a retainer, described ball is positioned at described retainer.
Also be provided with the second dustproof construction at the opposite side of described ball, this second dustproof construction comprises described first dust cover.
In described outer ring, inner peripheral surface is provided with the first circular groove, and described first dust cover is fixed in described first circular groove.
In described first circular groove, be also provided with a jump ring, described first dust cover is fixed in described first circular groove by this jump ring.
Described inner ring outer circumferential face is provided with the second circular groove, and described second dust cover is fixed in described second circular groove.
Described second dust cover is welded in described circular groove.
As preferably, the channel center of described double seal miniature bearing departs from bearing centre; Further, the channel center of described bearing departs from the distance of bearing centre is 0.20mm.
Compared with prior art, the invention has the beneficial effects as follows:
1, the side that bearing contacts with external environment condition is provided with the first dustproof construction, this dustproof construction comprises the first dust cover and the second dust cover, not only on the basis of original one sealing and dustproof, add one sealing and dustproof, and first dust cover and the second dust cover be separately fixed at inner ring and outer ring, inner ring and outer ring relatively rotate, so also rotate between the first dust cover and the second dust cover, form stable air-flow between, prevent entering of dust, dust-proof effect promotes greatly, be applicable to bad border severe, and require again the good application of bearing flexibility, for example flowmeter etc.
2, the first dust cover of the present invention and the second dust cover are all fixed in circular groove, improve the stability that dust cover connects, make the anti-dust performance that bearing is stable when high speed rotating.
3, on original basis, do not change the size of steel ball, and the method adopting raceway groove to offset abdicates space, ensure bearing at work, between (except rolling portion) each parts, there is no phase mutual friction, ensure bearing flexibility.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention; Fig. 2 is the schematic diagram of the first circular groove and the second circular groove in the embodiment of the present invention; Fig. 3 is the structural representation of raceway groove skew in the embodiment of the present invention.
Wherein: 1, inner ring; 2, outer ring; 3, steel ball; 4, retainer; 5, the first dust cover; 6, the second dust cover; 7, jump ring; 8, the first circular groove; 9, the second circular groove; A, channel center; B, bearing centre.
Embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated:
As shown in Figure 1, Figure 2, Figure 3 shows, this practical double seal miniature bearing, comprises inner ring 1, outer ring 2, ball 3 and retainer 4, and wherein retainer makes ball be placed in uniformly between inner ring 1 and outer ring 2.The side of ball is provided with the first dustproof construction, the opposite side of ball is provided with the second dustproof construction, first dustproof construction comprises the first dust cover 5 being fixed on outer ring 2 inner peripheral surface and the second dust cover 6, second dustproof construction being fixed on inner ring 1 outer circumferential face comprises the first dust cover.
The distance that first dust cover 5 and the distance of inner ring outer circumferential face are 0.7mm second dust cover and outer ring inner peripheral surface is 0.2mm.
In order to reliable and stable fixes the first dust cover 5 and the second dust cover 6, outer ring inner peripheral surface is provided with the first circular groove 8, and be then fixed in the first circular groove 8 by the first dust cover 5, means of fixation can select jump ring 7, maintenance for convenience detach.Inner ring outer circumferential face is provided with the second circular groove 9, is then fixed in the second circular groove 9 by the second dust cover 6, means of fixation can be welding or other modes.
The distance that the channel center a of described bearing departs from bearing centre b is 0.20mm.
