The utility model provides a pair of angular contact bearing guarantees lubricated smooth and easy, even through increasing oil groove and oilhole to mode through adopting four point contact makes steel ball and oilhole contactless, has reduced abnormal wear, has improved the life of bearing.
Description
Technical Field
The utility model relates to a bearing, especially an angular contact bearing.
Background
The existing bearing is frequently used, because the bearing does not have an oil guide groove and an oil inlet groove, only end face lubrication and oil injection can be performed in the using process, and the problems of unsmooth lubrication, uneven lubrication, untimely lubrication and the like can be caused frequently, so that abnormal wear and failure of the bearing are caused.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the utility model provides an angular contact bearing that lubricated smooth and easy, lubricated even, wearing and tearing are little, long service life, concrete technical scheme is:
an angular contact bearing comprising: the outer circular surface of the inner ring is provided with an outer groove; the oil hole is positioned at the bottom of the oil groove and communicated with the inner groove, and the oil hole is positioned at the center of the inner groove; the steel ball is positioned between the outer groove and the inner groove and is in four-point contact with the outer groove and the inner groove; the steel ball is movably arranged on the retainer.
By adopting the technical scheme, the oil groove is additionally arranged on the outer circular surface of the outer ring, the oil groove can guide and store the lubricant, so that the lubricant enters the inside of the bearing through the oil hole, namely the lubricant enters the outer groove, the inner groove and the steel ball, the lubricant is uniformly distributed, the continuous lubrication can be kept, the abrasion of the bearing is reduced, the service life of the bearing is prolonged, and the problem that the lubricant is difficult to enter the inside of the bearing when the lubricant is added into the bearing from the end surface of the existing bearing is solved.
Compared with the prior art the utility model discloses following beneficial effect has:
the utility model provides a pair of angular contact bearing guarantees lubricated smooth and easy, even through increasing oil groove and oilhole to mode through adopting four point contact makes steel ball and oilhole contactless, has reduced abnormal wear, has improved the life of bearing.
Drawings
FIG. 1 is a schematic cross-sectional view of an angular contact bearing;
fig. 2 is a partially enlarged schematic view of an angular contact bearing.
Detailed Description
The present invention will now be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, an angular contact bearing includes: the outer circle surface of the inner ring 1 is provided with an outer groove 11; the oil-gas separation device comprises an outer ring 2, wherein an inner circular surface of the outer ring 2 is provided with an inner groove 23, an outer circular surface of the outer ring 2 is provided with a plurality of oil grooves 21 and a plurality of oil holes 22, the oil holes 22 are annularly arrayed around the axis of the outer ring 2, the oil holes 22 are positioned at the bottom of the oil grooves 21 and communicated with the inner groove 23, and the oil holes 22 are positioned at the center of the inner groove 23; the steel ball 4 is positioned between the outer groove 11 and the inner groove 23, and is in four-point contact with the outer groove 11 and the inner groove 23;
the steel ball bearing comprises a retainer 3, and a steel ball 4 is movably arranged on the retainer 3.
The outer disc of outer lane 2 has increased oil groove 21, and oil groove 21 can water conservancy diversion and storage emollient, makes emollient pass through oilhole 22 and enters into the inside of bearing, and on emollient entered into outer slot 11, interior slot 23 and steel ball 4 promptly, realize the evenly distributed of emollient to can keep lasting lubrication, reduce the wearing and tearing of bearing, improve the life-span of bearing, solve current bearing from the terminal surface when adding emollient problem inside the bearing of being difficult for entering into.
The outer groove 11 of the inner ring 1 is composed of two symmetrical arcs, the outer groove 11 is peach-shaped, and the steel ball 4 is in two-point contact with the outer groove 11.
The inner groove 23 of the outer ring 2 is also composed of two symmetrical circular arcs, the inner groove 23 is peach-shaped, the oil hole 22 is positioned at the symmetrical center of the inner groove 23, and the steel ball 4 is also in two-point contact with the inner groove 23.
The steel ball 4 is in four-point contact with the inner groove 23 and the outer groove 11, the oil hole 22 is located at the lowest position of the inner groove 23, the oil hole 22 cannot be in contact with the steel ball 4, and the steel ball 4 cannot be damaged.
The utility model provides a pair of angular contact bearing guarantees lubricated smooth and easy, even through increasing oil groove and oilhole to mode through adopting four point contact makes steel ball and oilhole contactless, has reduced abnormal wear, has improved the life of bearing.
The technical principle of the present invention is described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the claims of the present invention.
