この発明は、ラッピングテープを用いて玉軸受のポール
軌道溝を超仕上加工方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method of superfinishing the pole raceway grooves of a ball bearing using a wrapping tape.
ラッピングテープを用いて玉軸受の軌道溝を研摩する超
仕上加工装置を本件出願人は特願昭５９−１０４３号明
細書において既に提案している。The present applicant has already proposed a superfinishing device for polishing raceway grooves of ball bearings using lapping tape in Japanese Patent Application No. 59-1043.
上記明細書に示された超仕上加工装置は、外輪の内径面

るようにしている。The super-finishing device shown in the above specification is explained by taking as an example the case where the raceway groove provided on the inner diameter surface of the outer ring is polished, but it is also possible to polish the raceway groove on the outer diameter surface of the inner ring in the same way. can. The superfinishing method in this case is as shown in FIG. The abrasive coated surface of the lapping tape 10 drawn out along the tip surface of the tape pressing member 3 is pressed against the raceway groove 2 by the pressing member 3, and in this state, the lapping tape is pressed against the raceway groove 2. 10 is moved in the length direction, the tape pressing member 3 is swung around the center of curvature of the raceway groove 2 as the center of oscillation, and the raceway ring 1 is further rotated in one direction.
ここで、ラッピングテープ１０は、第３図に示すように

とするラッピングテープ１０を用いて研摩作業を行なう
ようにしていた。Here, as shown in FIG. 3, the lapping tape 10 is made by uniformly coating abrasive grains 13 on one side of a thin film 11 made of polyester or the like through an adhesive layer 12, and has the above-mentioned raceway grooves. Conventionally, alumina abrasive grains or silicon carbide abrasive grains were used as polishing abrasive grains 13 for super finishing in step 2.
The polishing work was performed using a wrapping tape 10 having the following properties.
ところで、上記のようなラッピングテープを用いる超仕
上げ方法においては、研摩中にアルミナ系砥粒や炭化硅

図に示すように、軌道輪１の軌道溝２に周方向の不均一
なスジ４が残り、玉軸受を構成した場合に、異音が発生
するという不都合があった。By the way, in the superfinishing method using lapping tape as described above, alumina abrasive grains and silicon carbide abrasive grains often break and fall off during polishing, and as a result, the
As shown in the figure, uneven circumferential streaks 4 remain in the raceway groove 2 of the raceway ring 1, which causes an inconvenience in that abnormal noise is generated when a ball bearing is constructed.

合がある。In addition, unlike polishing with a grindstone, the lapping tape 10 described above has a limited abrasive layer, so it is easily clogged.
It is necessary to process the tape by changing it several times, and if the tape pressing force is increased, there are problems such as tape breakage.

る。In order to achieve the above object, the present invention employs a lapping tape coated with cubic boron nitride abrasive grains, and the abrasive grain surface of the lapping tape is pressed into the raceway groove of the raceway ring by the pressing action of a tape pressing member. The tape pressing member is oscillated around the center of curvature of the raceway groove as the center of oscillation while moving the wrapping tape in the length direction, and the raceway ring is rotated in one direction to super finish the raceway groove. It is processed.

。When superfinishing the raceway groove 2, as in the past, with the abrasive grain surface of the lapping tape 1o pressed against the raceway groove 2, the lapping tape 10 is moved in the length direction to align the center of curvature of the raceway groove 2. The tape pressurizing member 3 is oscillated about the oscillation center, and the bearing ring 1 is rotated at high speed in one direction.

る。As described above, according to the present invention, the raceway grooves of the raceway ring are superfinished using a lapping tape coated with low grains of cubic boron nitride, which is harder than diamond and has inter-fold properties. Since it is machined, the superfinishing process leaves uniform machining lines in the raceway groove, which is advantageous for reducing noise generated from the ball bearing when a ball bearing is constructed.
また、砥粒の破砕が少ないため、テープ交換の頻度が低
