Abstract
The utility model discloses a kind of bearing, comprise inner ring, outer ring, retainer, dust cover and several balls; Described inner ring and outer ring are coaxially put, described ball to be arranged on retainer and and retainer be together arranged between inner ring and outer ring, this ball annular is uniform and on the disc of embedded inner ring and outer ring, described inner ring and outer ring all arrange step otch relative to the one end near ball, an acute angle is formed between the bottom surface of described step otch and side, described dust cover is between inner ring and outer ring, its two ends are provided with a projection and hypotenuse obtuse-angulate with its shape, and described hypotenuse is connected in acute angle.Bearing lubrication effect of the present utility model clearly.
Description
Technical field
The utility model belongs to mechanical revolving part apparatus field, is specifically related to a kind of bearing.
Background technique
Existing bearing includes inner ring, outer ring and dust cover, there is gap between described outer ring and dust cover and between outer ring and dust cover, therefore dust allows and easily enters in this gap, so can affect lubrication effect very much.
Model utility content
(1) technical problem that will solve
The technical problems to be solved in the utility model to prevent dust from entering in ball.
(2) technological scheme
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of bearing, comprises inner ring, outer ring, retainer, dust cover and several balls; Described inner ring and outer ring are coaxially put, described ball to be arranged on retainer and and retainer be together arranged between inner ring and outer ring, this ball annular is uniform and on the disc of embedded inner ring and outer ring, described inner ring and outer ring all arrange step otch relative to the one end near ball, an acute angle is formed between the bottom surface of described step otch and side, described dust cover is between inner ring and outer ring, its two ends are provided with a projection and hypotenuse obtuse-angulate with its shape, and described hypotenuse is connected in acute angle.
The middle of described dust cover is protruding towards outside.
One deck epoxy resin is injected with between described hypotenuse and acute angle.
The material of described dust cover is plastics.
The angle of described acute angle is 75 °.
The middle of described dust cover is provided with a protruding step surface.
(3) beneficial effect
Bearing of the present utility model, by arranging acute angle at the step otch of inner ring and outer ring, by acute angle and hypotenuse clamping, making dust cover two ends be connected with inner ring and outer ring respectively, not easily making dust be not easy to enter in ball, therefore improve lubrication effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of bearing of the present utility model;
Fig. 2 is the sectional view of A-A in Fig. 1;
Fig. 3 is the enlarged view of B in Fig. 2;
1 be inner ring, 2 be outer ring in figure, 3 be retainer, 4 be dust cover, 5 be ball, 6 be step otch, 7 be acute angle, 8 be hypotenuse, 9 for step surface.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
A kind of bearing as shown in Figure 1-Figure 3, comprises inner ring 1, outer ring 2, retainer 3, dust cover 4 and several balls 5; The material of described dust cover 4 is plastics.Described inner ring 1 is coaxially put with outer ring 2, described ball 5 to be arranged on retainer 3 and and retainer 3 be together arranged between inner ring 1 and outer ring 2, uniform and the embedded inner ring 1 of this ball 5 annular is with on the disc of outer ring 2, described inner ring 1 all arranges step otch 6 with outer ring 2 relative to the one end near ball 5, an acute angle 7 is formed between the bottom surface of described step otch 6 and side, the angle of described acute angle 7 is 75 °, described dust cover 4 is between inner ring 1 and outer ring 2, its two ends are provided with a projection and hypotenuse 8 obtuse-angulate with its shape, described hypotenuse 8 is connected in acute angle 7, thus make dust cover 4 cover ball 5, and sealing effect is relatively good comparatively speaking by the configuration at acute angle and obtuse angle, make dust can not enter into ball 5, improve lubrication effect.
The middle of described dust cover 4 is protruding towards outside.
One deck epoxy resin is injected with between described hypotenuse 8 and acute angle 7.
The middle of described dust cover 4 is protruding towards outside.And form a protruding step surface 9, total and increase the placement amount of lubricant oil.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
