Abstract
The invention discloses a double-bearing dustproof bearing end cover, aiming at solving the problem that the bearing cover in the prior art often does not have a good sealing function due to the self structure, so that accidents are easily caused by end covers. The double-bearing dustproof bearing end cover comprises a cover body, bearing sleeves and a reinforcing rib, wherein the end surface of the cover body is provided with two through holes; the outer sides of the two through holes are respectively connected with the two bearing sleeves; the diameters of the bearing sleeves are the same as those of the through holes; the reinforcing rib is arranged between the two bearing sleeves; the cover body is provided with a sealing groove along the outer circumference side of a bearing hole; a sealing gasket is arranged in the sealing groove in a matching way. According to the double-bearing dustproof bearing end cover, two bearing end covers are spliced into a whole, so that the cost is saved, and the stability of a system is improved; the bearing cover is provided with the sealing groove and the sealing gasket which are matched with each other, so that outside dust impurities are prevented from being plugged into a bearing, and the normal operation of the bearing is guaranteed.
Description
Technical field
The present invention relates to mechanical Component field, particularly be a kind of duplex bearing shield bearing end cap.
Background technique
In the using process of automobile bearing; in order to guarantee the good operation of bearing; usually need protect extraneous dust impurity not enter in the bearing machinery by bearing cap is set; but the bearing cap of prior art is by the reason of self structure; often can not accomplish preferable seal action; the bearing cap of motor generally is to be made of materials such as cast iron, cast steel, steel plates, and bearing cap also has effect dustproof and sealing except it has the axially locating effect.Motor is in torque demand than under the heavy load situation, and shaft of motor can produce the distortion of trace.Because the matching gap between bearing cap and the rotating shaft is very little, cause the phase mutual friction between rotating shaft and internal bearing cover easily, the friction of iron and iron can produce high temperature, make the temperature of rotating shaft and internal bearing cover sharply rise, the rotating shaft temperature will be transmitted energy after raising towards periphery, will receive the energy that transmits from its nearest bearing so.Because the rapid rising of temperature can cause bearing inner race to expand like this, eats up the oil clearance of bearing inner race, ball and outer ring, finally causes the bearing sintering, the motor stall.Motor is if not protection will cause burn-down of electric motor.In addition, some high temperature, have the place of chemical corrosivity, bearing cap is easy to corrosion and wipes mutually with rotating shaft, causes motor bearings to burn.。
Summary of the invention
The present invention has overcome the shortcoming of prior art, and a kind of duplex bearing shield bearing end cap is provided.
To achieve these goals, the present invention realizes by the following technical solutions:
A kind of duplex bearing shield bearing of the present invention end cap comprises lid, bearing housing, stiffening rib, has two through holes on the described lid end face, and the through hole outside connects two bearing housings, and the diameter of bearing housing is identical with the diameter of through hole, is provided with stiffening rib between two bearing housings; Wherein, described lid is provided with seal groove along the outer circumferential sides of described bearing hole, is combined with sealing gasket in the described seal groove;
The material of described lid is high-strength cast steel;
The width of described stiffening rib is half of bearing housing diameter;
The material of described sealing gasket is DMC.
Beneficial effect of the present invention: two bearing (ball) covers are combined into one; provide cost savings, increased the stability of system, by seal groove and the sealing gasket that can cooperate bearing cap setting; can protect and not fill in extraneous dust impurity in the bearing, guarantee the normal operation of bearing.

Fig. 2 is the worm's eye view of structural representation of the present invention;
Fig. 3 is the left view of structural representation of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
As Fig. 1, Fig. 2, shown in Figure 3, a kind of duplex bearing shield bearing end cap, comprise lid 1, bearing housing 2, stiffening rib 3 that high-strength cast steel is cast, the through hole 4 that to have two diameters on the described lid end face be 10cm, through hole 4 outsides connect two bearing housings 2, the diameter of bearing housing 2 is identical with the diameter of through hole 4, is 10cm, is provided with stiffening rib 3 between two bearing housings 2; The width of stiffening rib is 5cm, and wherein, described lid 1 is provided with seal groove 5 along the outer circumferential sides of described bearing hole, and cooperating the employing material in the described seal groove is the sealing gasket of DMC.
Two bearing (ball) covers of the present invention are combined into one, provide cost savings, and have increased the stability of system, by seal groove and the sealing gasket that can cooperate bearing cap setting, can protect and not fill in extraneous dust impurity in the bearing, guarantee the normal operation of bearing.
More than show and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof
