Abstract
The utility model discloses a pressure-resistant bearing, which comprises an outer ring and an inner ring, wherein primary steel balls are arranged between the outer ring and the inner ring; primary rolling grooves, which are used for rolling of the primary steel balls, are formed in the inner side of the outer ring and in the outer side of the inner ring; a second rolling groove and a third rolling groove are formed in the two sides of the primary rolling groove of the outer ring; a fourth rolling groove and a fifth rolling groove, which are matched with the second rolling groove and the third rolling groove, are formed in the outer side of the inner ring; auxiliary steel balls are arranged both between the second rolling groove and the fourth rolling groove and between the third rolling groove and the fifth rolling groove; the diameter of each primary steel ball is greater than that of each auxiliary steel ball. The pressure-resistant bearing has the beneficial effects that the bearing adopts three groups of steel balls for supporting between the outer ring and the inner ring at the same time, so that the bearing pressure of each steel ball is reduced, the bearing capacity of the bearing is improved, and the service time of the bearing are prolonged.
Description
Technical field
The utility model belongs to field of bearings, relates in particular to a kind of resistance to compression bearing.
Background technique
Existing bearing generally only has row's steel ball, and the lifting surface area of the inside and outside ring of its steel ball and bearing is less, and the pressure that causes the steel ball of bearing to bear is very big, and under long-time pressure, steel ball is yielding, causes the rolling of steel ball limited, thereby affects the rolling effect of bearing.
The model utility content
The purpose of this utility model is the deficiency for above-mentioned technology, and a kind of measuring body bearing that has is provided.
To achieve these goals, the utility model is that the technological scheme that its technical problem of solution is taked is:
A kind of resistance to compression bearing, comprise outer shroud and interior ring, be provided with main steel ball between outer shroud and interior ring, inner and the outside main slot rolling rolled for main steel ball that is provided with of interior ring at outer shroud, be respectively equipped with the second slot rolling and the 3rd slot rolling on the both sides of described outer shroud master slot rolling, be provided with the 4th slot rolling and the 5th slot rolling that are complementary with the second slot rolling and the 3rd slot rolling on described interior ring outside, and be equipped with secondary steel ball between the second slot rolling and the 4th slot rolling and the 3rd slot rolling and the 5th slot rolling.
Further, the diameter of described main steel ball is greater than the diameter of secondary steel ball.
The beneficial effects of the utility model: the utility model adopts three groups of steel balls to be supported between outer shroud and interior ring simultaneously, makes the pressure that bears of each steel ball reduce, thereby improves the bearing capacity of bearing, the working life of improving bearing.
The accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Embodiment
In order to make the utility model be convenient to understand, below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of resistance to compression bearing as shown in Figure 1, comprise outer shroud 1 and interior ring 2, be provided with main steel ball 3 between outer shroud 1 and interior ring 2, be provided with in outer shroud 1 inside and interior ring 2 outsides the main slot rolling 4 rolled for main steel ball 3, it should be noted that, be respectively equipped with the second slot rolling 5 and the 3rd slot rolling 6 on the both sides of described outer shroud master slot rolling 4, be provided with the 4th slot rolling 7 and the 5th slot rolling 8 that are complementary with the second slot rolling 5 and the 3rd slot rolling 6 on described interior ring 2 outsides, and be equipped with secondary steel ball 9 between the second slot rolling 5 and the 4th slot rolling 7 and the 3rd slot rolling 6 and the 5th slot rolling 8.
Further it should be noted that the diameter of described main steel ball 3 is greater than the diameter of secondary steel ball 9.
The utility model adopts three groups of steel balls to be supported between outer shroud and interior ring simultaneously, makes the pressure that bears of each steel ball reduce, thereby improves the bearing capacity of bearing, the working life of improving bearing.
Above demonstration and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope, those ordinary skill in the art's simple change and replacement are all within protection domain of the present utility model.
Claims (2)
