本発明は損傷、摩耗等によって使用できなくなったヘア
リングの再生加工法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for recycling hair rings that have become unusable due to damage, wear, or the like.
損傷、摩耗等によって使用できなくなったベアリングは
スクラップとして廃棄されているが、通常その内輪、外
輪とボールあるいはコロ等の転動体の全てが損傷あるい
は均等に摩耗していることはまれである。Bearings that can no longer be used due to damage, wear, etc. are discarded as scrap, but it is rare that all of the inner ring, outer ring, and rolling elements such as balls or rollers are damaged or evenly worn.
ベアリングは同型式のものでも、それを使用している機
械の種類及び状況等の相違により、内輪。Even if the bearings are of the same type, the inner ring may differ depending on the type and situation of the machine in which it is used.
外輪、転動体のいずれか異なるものが損傷あるいは摩耗
することが多い。しかも内輪、外輪、転動体のいずれか
１つが損傷あるいは摩耗しても回転に支障が生しるため
に新しいベアリングに交換している。Often, either the outer ring or the rolling elements are damaged or worn out. Moreover, even if any one of the inner ring, outer ring, or rolling element is damaged or worn, rotation will be hindered, so the bearing must be replaced with a new one.
従って、例えば内輪の損傷により使用不能になって取り
外したベアリングの場合には、外輪及び転動体には損傷

動体が多く含まれている。Therefore, for example, in the case of a bearing that has become unusable due to damage to the inner ring and has been removed, the outer ring and rolling elements are undamaged, have little wear, and have a predetermined dimensional accuracy. That is, conventional bearings that are discarded as scrap contain many reusable inner rings, outer rings, or rolling elements.

生加工法に関するもので、その目的は従来廃棄されてい
るベアリングの有効利用を図ることにある。The outer ring and rolling elements are adjusted to the required clearance accuracy, one rotation end degree, etc., and then assembled to form the required bearing, and among the selected inner rings, outer rings, and rolling elements that cannot be combined with each other, those of the same type as these are assembled. , relates to a method of remanufacturing bearings that combine unused inner rings, outer rings, or rolling elements, adjust the required clearance accuracy per revolution, etc., and then assemble them into the required bearings. The aim is to make effective use of bearings.
以下には円筒コロ軸受型式のヘアリングを再生加工する
実施例について説明する。An example of reprocessing a cylindrical roller bearing type hair ring will be described below.
まず、圧延機等で使用し損傷あるいは摩耗等により使用
できなくなった円筒コロ軸受型式のベアリングを６０個
回収し、それぞれ内輪と外輪と転動体たる円筒コロとコ
ロ保持器に分解する。First, we collect 60 cylindrical roller bearings that were used in rolling mills and are no longer usable due to damage or wear, and disassemble them into an inner ring, an outer ring, cylindrical rollers as rolling elements, and a roller retainer.
上記分解した内輪、外輪９円筒コロ及びコロ保持器をそ
れぞれ検査して損傷がなく、かつ所定の寸法精度を有す
る内輪、外輪２円筒コロ及びコロ保持器を選別する。す
なわち、損傷については内。The disassembled inner ring, outer ring 9 cylindrical rollers, and roller retainer are each inspected to select the inner ring, outer ring 2 cylindrical rollers, and roller retainer that are free from damage and have predetermined dimensional accuracy. In other words, damage is included.
外輪の起動面にピッチング、フレーキング、圧こん、打
こん等があるか、円筒コロあるいはコロ保持器に欠け、
フレーキングがあるか等を検査する。Is there any pitting, flaking, dents, dents, etc. on the starting surface of the outer ring, or is the cylindrical roller or roller retainer chipped?
Inspect for flaking, etc.
また、所定の寸法精度については、例えば呼び外径が、
１８０〜２５０１の外輪の場合には外径の寸法差（並級
）が（上）＋８μ、 （下）−３８μ以内に対応してい

２個、コロ保持器を４６個、円筒コロを４０組分ずつ選
別し、それらの潤滑油。In addition, regarding predetermined dimensional accuracy, for example, the nominal outer diameter is
In the case of outer rings from 180 to 2501, it is inspected to see if the difference in outer diameter (normal grade) corresponds to within +8μ (top) and -38μ (bottom). As a result of the above inspection, for example, 50 inner rings and 4 outer rings were found to be undamaged and had the specified dimensional accuracy.
Lubricating oil for 2 rollers, 46 roller retainers, and 40 cylindrical rollers.
塵埃等の汚れを洗浄する。Clean away dirt such as dust.
しかるのち、それら内輪、外輪１円筒コロ、及びコロ保
持器を適宜組み合せて所要の隙間精度。After that, the inner ring, outer ring 1 cylindrical roller, and roller retainer are appropriately combined to obtain the required clearance accuracy.
回転精度等を、新品のベアリングにおける使用目的に対
応した種々の所定の規格のいずれか所要のものに合致す
るように調整する。The rotational accuracy and the like are adjusted to meet any one of various predetermined standards corresponding to the purpose of use of the new bearing.
すなわち、隙間精度については、例えばラジアル隙間の
軸受内径の呼び寸法が８０〜１００鶴の場合には、（普

Ｃ４）最小１３５μ、最大１８０μの各所定の規格のい
ずれか所望の規格に合致する隙間精度が得られるように
組み合せて調整する。That is, regarding the clearance accuracy, for example, if the nominal size of the bearing inner diameter of the radial clearance is 80 to 100 Tsuru, (normal) minimum 60μ, maximum 100μ, (C2) minimum 35μ,
Maximum 60μ, (C3) Minimum 100μ, Maximum 135μ, (
C4) Combine and adjust so as to obtain a gap accuracy that meets the desired standard of each predetermined standard of minimum 135μ and maximum 180μ.
また、回転精度については、例えば外輪の呼び外径が１
８０〜２５０龍の場合には外輪の偏心が５０μ以内であ

、各所定の規格のいずれかに合致する回転精度が得られ
るように組み合せて調整する。Regarding rotation accuracy, for example, the nominal outer diameter of the outer ring is 1
In the case of 80 to 250 dragons, the eccentricity of the outer ring is within 50μ, and when the nominal inner diameter of the inner ring is 80 to 120 am, the eccentricity and lateral runout of the inner ring are each within 25μ (normal grade), so each specified Combine and adjust to obtain rotation accuracy that meets one of the standards.

望の再生ベアリング５を例えば合計３８個得る。In this way, we comprehensively check the dimensional accuracy of the selected inner ring, outer ring 2 cylindrical rollers, and roller retainer, the range of possible combinations in terms of clearance accuracy, 1 rotation end degree, etc., and the rotational accuracy of the predetermined standard corresponding to the purpose of use of the remanufactured bearing. Inner rings that can be combined with each other are selected by taking into consideration the combination with the highest regeneration efficiency. The inner ring 2° roller retainer 3 and one set of cylindrical rollers 4 are arranged for each set, and the required adjustments are made and assembled to obtain, for example, a total of 38 desired recycled bearings 5.
これにより、前記の選別された内輪、外輪９円筒コロ及

内輪が１２個、外輪が４個、コロ保持器が８個、円筒コ
ロが２組分残る。As a result, among the selected inner and outer rings, 9 cylindrical rollers, and roller retainers, those that could not be used for assembling the remanufactured bearing 5, namely, 12 inner rings, 4 outer rings, and roller retainers, which cannot be assembled with each other. Eight bowls and two sets of cylindrical rollers remain.

Combined with outer ring, cylindrical roller and roller retainer, 1
By arranging two sets, making necessary adjustments, and assembling them, for example, a remanufactured bearing 7 can be obtained, which is a combination of a used inner ring 1 and outer ring 2 and an unused roller retainer 6 and cylindrical rollers.
A total of 12 remanufactured bearings were obtained, each consisting of an unused outer ring, one cylindrical roller, or a roller retainer.

されていた再使用可能な内輪。As is clear from the above description, according to the present invention,
We disassemble multiple bearings of the same type that are unusable due to damage, wear, etc., and select inner rings, outer rings, and rolling elements that are undamaged and have the specified dimensional accuracy, and which can be combined with each other. A remanufactured bearing is obtained by assembling the bearings after adjusting the required clearance accuracy, etc., and also with the inner rings selected above that cannot be combined with each other, and with unused inner rings, outer rings, or rolling elements of the same type. A reusable inner ring that used to be discarded because a recycled hair ring can be obtained by combining and assembling the required gap accuracy, etc.
外輪、転動体の全てを再生利用し得て経済的である。It is economical because the outer ring and rolling elements can all be recycled.
