Abstract
The utility model provides a kind of deep groove ball bearing, comprise bearing inner race, bearing outer ring and retainer, described retainer is provided with ball, be characterized in that the both sides of described bearing outer ring are radially asymmetric and be provided with left and right dust cover, described left and right dust cover interference fit is between described bearing outer ring and described bearing inner race, what the both sides of described bearing inner race were radially symmetrical is provided with " V " groove, and the side of described bearing outer ring is provided with the notch in " C " type corresponding with described " V " groove.This technological scheme structure is simple and can have dust-proof, grease-proof concurrently and to leak performance.
Description
Technical field
The utility model relates to a kind of deep groove ball bearing, belongs to " F16C axle in International Patent Classification (IPC); Flexible axle; The element of crank mechanism; Rotatable parts except transmission component; Bearing " technical field.
Background technique
Deep groove ball bearing is a type the most common in rolling bearing, the deep groove ball bearing of basic model is by an outer ring, an inner ring, one group of steel ball and one group of retainer are formed, it is divided into sealing and open type two kinds of structures, open type refers to that bearing is not with sealing configuration, and sealed type deep-groove ball is divided into dust sealing and anti-oil seal.Traditional dust sealing cover material is steel plate punched, only play and simply prevent dust from entering bearing race, and oilproof is contact oil seal, can effectively stop the lubricating grease in bearing excessive.
But the deep groove ball bearing of contact oil seal of the prior art in use for some time, its dust-proof effect can decline, especially at the working environment that dust, silt and rainwater are relatively many, oil sealing more can not effectively be resisted and make it enter Bearing inner, make deep groove ball bearing easily occur premature wear or damage, add the cost of enterprise.
Summary of the invention
In view of this, the utility model object is to provide a kind of structure and simply also can has dust-proof, that grease-proof leaks performance deep groove ball bearing concurrently.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of deep groove ball bearing, comprise bearing inner race, bearing outer ring and retainer, described retainer is provided with ball, the both sides of wherein said bearing outer ring are radially asymmetric is provided with left and right dust cover, described left and right dust cover interference fit is between described bearing outer ring and described bearing inner race, what the both sides of described bearing inner race were radially symmetrical is provided with " V " groove, and the side of described bearing outer ring is provided with the notch in " C " type corresponding with described " V " groove.
Preferably, above-mentioned deep groove ball bearing, the angle of inclination of wherein said " V " groove bi-side is respectively α, β, described α=30 °, described β=5 °.
Preferably, above-mentioned deep groove ball bearing, the outer rim of wherein said notch is skewed, and its angle of inclination is δ, described δ=45 °.
Preferably, above-mentioned deep groove ball bearing, wherein said left and right dust cover is barb shape.
Preferably, above-mentioned deep groove ball bearing, the radial internal clearance of wherein said deep groove ball bearing is 3 ~ 18um.
Technique effect of the present utility model is mainly reflected in: the both sides of the utility model middle (center) bearing outer ring are radially asymmetric is provided with a left side, right dust cover, left, right dust cover interference fit can play effective dust-proof effect between bearing outer ring and described bearing inner race, what the both sides of bearing inner race were radially symmetrical simultaneously is provided with " V " groove, the side of described bearing outer ring is provided with the notch in " C " type corresponding with " V " groove, when deep groove ball bearing is in high-speed rotation, the notch of " V " groove and correspondence effectively can collect the grease leaked in high-speed rotation, and be unlikely to it and release outside dust cover.
Accompanying drawing explanation
Fig. 1: the utility model structural representation;
Fig. 2: the utility model bearing inner race structural representation;
Fig. 3: the utility model Tu2Zhong A district's enlarged diagram;
Fig. 4: the utility model bearing outer ring structural representation;
Fig. 5: the utility model Tu4Zhong B district's enlarged diagram.
In figure, the implication of each reference character is: 1-bearing inner race, 2-bearing outer ring, 3-retainer, 4-ball, the left dust cover of 5-, the right dust cover of 6-, 7-" V " groove, 8-notch.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail, is easier to make technical solutions of the utility model understand and grasp.
As shown in Figure 1, Figure 2 and Figure 4, a kind of deep groove ball bearing, comprise bearing inner race 1, bearing outer ring 2 and retainer 3, retainer 3 is provided with ball 4, wherein the both sides of bearing outer ring 1 are radially asymmetric is provided with left and right dust cover (5,6), left and right dust cover (5,6) interference fit is between bearing outer ring 2 and bearing inner race 1, what the both sides of bearing inner race 1 were radially symmetrical is provided with " V " groove 7, and the side of bearing outer ring 2 is provided with the notch 8 in " C " type corresponding with " V " groove 7.
As shown in Figure 3, the angle of inclination of " V " groove 7 bi-side is respectively α, β, wherein α=30 °, β=5 °.
As shown in Figure 5, the outer rim of notch 8 is skewed, and its angle of inclination is δ, δ=45 °.
Left and right dust cover (5,6) is in barb shape.
In addition, the radial internal clearance of this deep groove ball bearing is 3 ~ 18um.
By describing above and can finding out, the both sides of the utility model middle (center) bearing outer ring are radially asymmetric is provided with a left side, right dust cover, left, right dust cover interference fit can play effective dust-proof effect between bearing outer ring and described bearing inner race, what the both sides of bearing inner race were radially symmetrical simultaneously is provided with " V " groove, the side of bearing outer ring is provided with the notch in " C " type corresponding with " V " groove, when deep groove ball bearing is in high-speed rotation, the notch of " V " groove and correspondence effectively can collect the grease leaked due to centrifugal action in high-speed rotation, and be unlikely to it and release outside dust cover.
Certainly, the exemplary illustration of the above only the utility model typical apply, by the combination of same or similar technical characteristics and replacement, can form multiple concrete scheme, these schemes all drop within protection domain of the present utility model.
