Abstract
The utility model provides a deep-groove ball bearing, belongs to the technical field of machinary and solves the problems that the conventional deep-groove ball bearings are high in abrasion possibility and poor in air tightness. the deep-groove ball bearing comprises an outer ring, an inner ring and balls, wherein the outer ring comprises a first outer ring and a second outer ring, which are arranged closely in parallel; clamping grooves are formed in the end parts of the inner walls of the first outer ring and the second outer ring; an arc-shaped notch is formed in the end part of the inner ring; a seal ring is arranged between the outer ring and the inner ring; the outer wall of the seal ring is clung to the bottom surfaces of the clamping grooves; the inner wall of the seal ring is an arc surface and the arc surface is clung to the surface of the arc-shaped notch; a lug is arranged on the end face of the seal ring; the inner wall of the lug is clung to the inner ring; the first outer ring, the second outer ring and the inner ring are circular arc-shaped bulges. The deep-groove ball bearing has the advantages that the efficiency is high and the air tightness is good.
Description
Technical field
The utility model belongs to field of mechanical technique, is specifically related to a kind of deep groove ball bearing.
Background technique
Bearing is in mechanical transmission course, to work the parts of fixing and reducing load friction factor, also can say, when other parts produce relative movement each other on axle, is used for reducing the fixing parts of friction factor and retainer shaft central position in power transmission process.Bearing is a kind of very important component in contemporary machinery, its major function is supported mechanical solid of rotation, mechanical load friction factor in order to reduction equipment in transmission process, by the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing.
Deep groove ball bearing is one type the most common in rolling bearing, and traditional deep groove ball bearing consists of an outer ring, an inner ring and one group of steel ball, but deep groove ball bearing has following shortcoming conventionally: 1, load capacity is less, easy to wear; 2, tightness is poor; While 3, assembling, need to use auxiliary socket or forced installation method, complex procedures inconvenience, manufacturing efficiency is never high, manufactures also inconvenience of processing simultaneously.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for prior art, has proposed the deep groove ball bearing that a kind of efficiency is high, tightness is good.
The purpose of this utility model can realize by following technical proposal: a kind of deep groove ball bearing, comprise outer ring, inner ring and ball, described outer ring comprises the first outer ring and the second outer ring closely arranging side by side, the first described outer ring and the second inwall end, outer ring all offer draw-in groove, described inner ring end offers arc notch, between described outer ring and inner ring, be provided with seal ring, described seal ring outer wall and the laminating of the bottom surface of draw-in groove, described seal ring inwall is arc surface and arc surface and the laminating of arc notch surface, described seal ring end face is provided with projection, described projection inwall and inner ring laminating, the first described outer ring, the second outer ring and inner ring are arc-shaped convex.
In above-mentioned a kind of deep groove ball bearing, the outside, tight joint of the first described outer ring and the second outer ring is provided with rubber ring.
In above-mentioned a kind of deep groove ball bearing, described seal ring is embedded with skeleton.
In above-mentioned a kind of deep groove ball bearing, the first described outer ring and the second outer ring radian are greater than the circular arc radian of ball, and described inner ring radian is less than the circular arc radian of ball.
Compared with prior art, the utlity model has following advantage:
1, coordinating bearing seal of seal ring and draw-in groove and arc gap, gas can only flow into from outside bearing inside, and can not flow into from inside outsidely, realize one-way sealing, and good seal performance, has improved the whole tightness of bearing;
2, in joint, outer ring, set up and there is flexible rubber sleeve as preliminary fixing, after being installed on axle, by bearing (ball) cover, to be undertaken spacingly, the assembling of disassembly-type not only give to be manufactured processing and is brought great convenience, also improved manufacturing efficiency, there is high actual application value simultaneously;
3, the first outer ring and the second outer ring radian are greater than the circular arc radian of ball, inner ring radian is less than the circular arc radian of ball, designed arc-shaped appearance can make ball surface of contact when contacting with bearing inner race less, when contacting with bearing outer ring, surface of contact is larger, thereby guiding ball rolls, and has greatly reduced friction.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model one preferred embodiment.
In figure, the 1, first outer ring; 2, the second outer ring; 3, inner ring; 4, ball; 5, seal ring; 51, skeleton; 6, draw-in groove; 7, arc notch; 8, projection; 9, rubber ring.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this deep groove ball bearing comprises outer ring, inner ring 3 and ball 4, described outer ring comprises the first outer ring 1 and the second outer ring 2 closely arranging side by side, and the tight joint outermost that is provided with seal ring 5, the first outer rings 1 and the second outer ring 2 between described outer ring and inner ring 3 is provided with rubber ring 9.
In joint, outer ring, set up and there is flexible rubber ring 9 as preliminary fixing, after being installed on axle, by bearing (ball) cover, to be undertaken spacingly, the assembling of disassembly-type not only give to be manufactured processing and is brought great convenience, also improved manufacturing efficiency, there is high actual application value simultaneously.
The first outer ring 1 and 2 inwall ends, the second outer ring all offer draw-in groove 6, described inner ring end offers arc notch 7, described seal ring 5 outer walls and the laminating of the bottom surface of draw-in groove 6, described seal ring 5 inwalls are arc surface and arc surface and arc notch 7 surface laminatings, described seal ring 5 end faces are provided with projection 8, described projection 8 inwalls and inner ring 3 laminatings, described seal ring 5 is embedded with skeleton 51.
Seal ring 5 coordinates bearing seal with draw-in groove 6 and arc gap 7, and gas can only flow into from outside bearing inside, and can not from inside, flow into outside, realizes one-way sealing, and good seal performance, has improved the whole tightness of bearing.
The first outer ring 1, the second outer ring 2 and inner ring 3 structures are arc-shaped convex, the first outer ring 1 and the second outer ring 2 radians are greater than the circular arc radian of ball 4, described inner ring 3 radians are less than the circular arc radian of ball 4, designed arc-shaped appearance can make ball 4 surface of contact when contacting with bearing inner race less, when contacting with bearing outer ring, surface of contact is larger, thereby guiding ball 4 rolls, and has greatly reduced friction.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
