Abstract
The utility model relates to a kind of for forming the oilstone of convexity after raceway superfinishing, comprise oilstone body, described oilstone body is elongated, this oilstone body is provided with processing department, the utility model is simple in structure, adopt the oilstone of middle with hole or two sides trough of belt, in the time forming raceway superfinishing, the area of oilstone contact in the middle of raceway is different with the time contacting, raceway just can make the removal amount in the middle of raceway be less than the removal amount at raceway edge after superfinishing, thereby after reaching raceway superfinishing, there is projection amount centre, can ensure that roller bearing bears loads and increases the service life, the utility model is reasonable in design, be applicable to promoting in the industry.
Description
Technical field
The utility model relates to a kind of oilstone, relates in particular to a kind of for forming the oilstone of convexity after raceway superfinishing.
Background technology
The raceway Superfinishing machine that at present domestic each Production of bearing enterprise is used, in the time of superfinishing cylinder, the inside and outside raceway of conical bearing, generally specifies in technique that raceway protrudes in the middle of only being permitted after superfinishing, mustn't be recessed.Wherein, small size bearing raceway bulge quantity is defined as between 0.002-0.006mm not etc., but while using raceway Superfinishing machine superfinishing, the time stopping in the middle of raceway due to oilstone vibration is twice left and right than the time stopping at edge, therefore oilstone is also twice above to the removal amount in the middle of raceway than the removal amount at raceway edge accordingly, certainly will after fine abrasive, make like this to form the recessed heart in the middle of raceway, this unfavorable result can cause the contact area of rolling element and raceway to reduce, strengthen the contact stress at roller and raceway edge, make bearing produce fatigue wear prematurely, reduce the service life of bearing.
Utility model content
For the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide one can ensure that bearing bears load, increase the service life, improve machining accuracy for forming the oilstone of convexity after raceway superfinishing.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind ofly comprise oilstone body for forming the oilstone of convexity after raceway superfinishing, described oilstone body is elongated, and this oilstone body is provided with processing department.
Further, described processing department is circular hole, and this circular hole is arranged on oilstone body middle.
Further, described processing department is the first groove and the second groove, and this first groove is arranged on the middle above oilstone body, and this second groove is arranged on the middle below oilstone body.
Compared with prior art, the utility model has the advantage of: the utility model is simple in structure, adopt the oilstone of middle with hole or two sides trough of belt, in the time forming raceway superfinishing, the area of oilstone contact in the middle of raceway is different with the time contacting, raceway just can make the removal amount in the middle of raceway be less than the removal amount at raceway edge after superfinishing, thereby after reaching raceway superfinishing, there is projection amount centre, can ensure that roller bearing bears loads and increases the service life, the utility model is reasonable in design, is applicable to promoting in the industry.
Brief description of the drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is the cutaway view of the utility model embodiment 1;
Fig. 3 is the cutaway view of the utility model embodiment 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment, the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, 2, a kind ofly comprise oilstone body 1 for forming the oilstone of convexity after raceway superfinishing, described oilstone body 1 is elongated, and this oilstone body 1 is provided with processing department, and this processing department is circular hole 2, and this circular hole 2 is arranged on oilstone body 1 middle.
While forming raceway superfinishing, the area of this oilstone contact in the middle of raceway is different with the time contacting, raceway just can make the removal amount in the middle of raceway be less than the removal amount at raceway edge after superfinishing, thereby in the middle of reaching after raceway superfinishing, there is projection amount, can ensure that roller bearing bears load and increase the service life.
Embodiment 2
As shown in Figure 1,3, a kind of for forming the oilstone of convexity after raceway superfinishing, comprise oilstone body 1, described oilstone body 1 is elongated, this oilstone body 1 is provided with processing department, this processing department is the first groove 3 and the second groove 4, and this first groove 3 is arranged on oilstone body 1 middle above, and this second groove 4 is arranged on oilstone body 1 middle below.
While forming raceway superfinishing, the area of this oilstone contact in the middle of raceway is different with the time contacting, raceway just can make the removal amount in the middle of raceway be less than the removal amount at raceway edge after superfinishing, thereby in the middle of reaching after raceway superfinishing, there is projection amount, can ensure that roller bearing bears load and increase the service life.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, it will be understood by those of skill in the art that its technical scheme that still can record aforementioned each embodiment modifies, or part technical characterictic is wherein replaced on an equal basis; And these amendments or replacement do not make the essence of appropriate technical solution depart from spirit and the scope of the each embodiment technical scheme of the utility model.
Claims (3)
1. for forming an oilstone for convexity after raceway superfinishing, comprise oilstone body, it is characterized in that, described oilstone body is elongated, and this oilstone body is provided with processing department.
