Abstract

PURPOSE:To prevent a holding device from being broken and prolong the service life of a ball bearing by keeping the distance between rolling bodies by the balls made of resin. CONSTITUTION:Balls 2 made of resin are put between the rolling bodies 1 of a ball bearing. Therefore, the breakage of a holding device can be prevented by a centrifugal force, vibration, and gyro-effect in constitution. Further, the sliding friction between the holding device and the rolling bodies is not increased because of the gyro-effect, when the bearing shifts its direction.

Description

【発明の詳細な説明】 この発明は、転動体と転動体の間隔を、樹脂でできた玉
によって保持した、玉軸受に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ball bearing in which the distance between rolling elements is maintained by balls made of resin.

従来の保持器を使用した玉軸受では、高回転で、負荷変
動の激しい軸に使用した場合、たとえば、模型のレーシ
ングボート用エンジンのクランクシャフトに使用した場
合、短時間で保持器が破損してしまい、軸受ばか９でな
く、他の部品まで破損してしまうことが、しばしばあっ
た。When ball bearings with conventional cages are used on shafts that rotate at high speeds and undergo severe load fluctuations, for example on the crankshafts of model racing boat engines, the cage can break in a short period of time. This often resulted in damage not only to the bearing but also to other parts.

したがって、使用者は、これを防ぐため、保持器の寿命
をある程度予測して、定期的に軸受を交換していたが、
とれは、完全な解決方法にはならなかったし、とてもめ
んどうであった。Therefore, in order to prevent this, users had to predict the lifespan of the cage to some extent and replace the bearings periodically.
This was not a complete solution and was very troublesome.

本発明は、このような保持器の破損をなくし、玉軸受の
寿命を向上させることに成功したものである。The present invention has succeeded in eliminating such damage to the cage and improving the life of the ball bearing.

つぎに、その構造を説明すると、 玉軸受の転動体（１）と転動体（１）の間に樹脂の玉（

Insert 2).

このようにすれば構造上、円心力、振動、ジャイロ効果
によって、保持器が破損することはない。In this way, the cage will not be damaged due to circular force, vibration, or gyroscopic effect.

、た辿いに反対方向の運動をしているため、高速回転で

てしまう。しかし、転動体に比べてやわらかい樹脂の玉
であれば、このようなことは々い。Furthermore, when the direction of the bearing changes, the overall friction between the cage and the rolling elements does not increase due to the gyroscopic effect.6 However, even if the rolling elements are held in this way, if all rolling elements are used, the It may seem like no change, but if all rolling elements are used, the rolling elements will come into point contact, and at that point of contact, they will be moving in the opposite direction, so when used at high speeds, the rolling elements will slip and cause damage. It gets scratched and wears out. However, this often happens if the ball is made of resin, which is softer than the rolling element.

単に製作できる。In addition, deep-socket ball bearings are made of slightly elastic resin balls (
2), the rolling element (1) can be connected to the inner ring (3) and outer ring (4).
After arranging them at equal intervals between the rolling elements, resin balls can be inserted between the rolling elements through the gap between the inner and outer rings, making it easy to manufacture.

く、転動体と同じ回転をする必要も々いので、転動体よ
シ多少小さい径で、内輪と外輪のすきまより多少大きい

ことはない。In addition, since the resin balls only maintain the distance between the rolling elements, A-1:I) They do not receive a large load and need to rotate at the same rate as the rolling elements, so the rolling elements If the diameter is slightly smaller and slightly larger than the gap between the inner and outer rings, the rotation will be smooth and the resin balls will not come off during rotation.

これの実験結果をのべると、 転動体の間にふっ素樹脂でできた、直径が転動体の直径

れるなどの問題は全く起らなかった。The results of this experiment are as follows: A ball made of fluorine resin with a diameter of about 1 the diameter of the rolling element and about 1.07 times the size of the gap between the inner ring and outer ring was inserted between the rolling elements. I installed the deep groove ball bearing in a model engine and tested it many times at a rotational speed of 3000r and between pm and 30000rpm, but the rotation was smooth and there were no problems such as the resin balls coming off.

この実験では、ふっ素樹脂の玉を使ったが、実際には、

。In this experiment, we used fluororesin balls, but in reality,
It is best to use different types of resin beads depending on the purpose.
