[Means for Solving the Problems]
In order to solve the above-mentioned subject, the present invention consists of the following composition. That is, the rolling bearing according to claim 1 of the present invention comprises an inner ring, an outer ring, a plurality of rolling elements rollably disposed between the inner ring and the outer ring, and a space between the inner ring and the outer ring And a lubricant supply member made of a lubricant-containing polymer disposed in a gap formed therein and in which the rolling element is installed, wherein the lubricant supply member is an outer diameter surface of the inner ring or a lubricant supply member. The lubricant supply member is in contact with a part of a portion of the rolling element exposed in the gap portion while being fixed to the inner diameter surface of the outer ring.

【0008】
このような構成であれば、前記潤滑剤供給部材は、前記転動体の前記空隙部内に露出した部分のうち一部としか接触していないので、前記転動体の転動を阻害しにくい。また、前記潤滑剤供給部材は前記内輪の外径面及び前記外輪の内径面のいずれか一方に固定されているので、前記内輪及び前記外輪はその動きを阻害されることがない。したがって、転がり軸受の動トルクが低く、回転による温度上昇が少ないから、転がり軸受を高速回転で使用することが可能である。
また、本発明に係る請求項2の転がり軸受は、請求項1に記載の転がり軸受において、前記潤滑剤供給部材は、前記転動体に点接触していることを特徴とする。
さらに、本発明に係る請求項3の転がり軸受は、請求項1に記載の転がり軸受において、前記潤滑剤供給部材の前記転動体との接触部分は、凹面となっていることを特徴とする。
さらに、本発明に係る請求項4の転がり軸受は、請求項1〜3のいずれか一項に記載の転がり軸受において、前記潤滑剤供給部材は、前記内輪の外径面及び前記外輪の内径面の一方に固定されるとともに他方に接触していることを特徴とする。
さらに、本発明に係る請求項5の転がり軸受は、請求項1〜4のいずれか一項に記載の転がり軸受において、前記潤滑剤供給部材を、シール溝に圧入することにより固定したことを特徴とする。
さらに、本発明に係る請求項6の転がり軸受は、請求項1〜4のいずれか一項に記載の転がり軸受において、前記潤滑剤供給部材は、圧入によりシール溝に取り付けられた芯材と一体化されており、該芯材を介して前記内輪の外径面又は前記外輪の内径面に固定されていることを特徴とする。
さらに、本発明に係る請求項7の転がり軸受は、請求項1〜6のいずれか一項に記載の転がり軸受において、冠形保持器を備えており、該冠形保持器のつのが向いた側に前記潤滑剤供給部材が配されていることを特徴とする。
さらに、本発明に係る請求項8の転がり軸受は、請求項1〜7のいずれか一項に記載の転がり軸受において、深みぞ玉軸受又はスラストアンギュラ玉軸受であることを特徴とする。
[0008]
With such a configuration, since the lubricant supply member is in contact with only a part of the portion of the rolling element exposed in the gap, rolling of the rolling element is unlikely to be inhibited. Further, since the lubricant supply member is fixed to any one of the outer diameter surface of the inner ring and the inner diameter surface of the outer ring, the movement of the inner ring and the outer ring is not hindered. Therefore, since the dynamic torque of the rolling bearing is low and the temperature rise due to rotation is small, it is possible to use the rolling bearing at high speed rotation.
A rolling bearing according to a second aspect of the present invention is the rolling bearing according to the first aspect, wherein the lubricant supply member is in point contact with the rolling element.
Furthermore, according to a third aspect of the present invention, in the rolling bearing according to the first aspect, the contact portion of the lubricant supply member with the rolling element is concave.
Furthermore, the rolling bearing according to claim 4 of the present invention is the rolling bearing according to any one of claims 1 to 3, wherein the lubricant supply member comprises an outer diameter surface of the inner ring and an inner diameter surface of the outer ring. It is fixed to one side and is in contact with the other.
Furthermore, a rolling bearing according to a fifth aspect of the present invention is the rolling bearing according to any one of the first to fourth aspects, wherein the lubricant supply member is fixed by pressing into the seal groove. I assume.
Furthermore, according to a sixth aspect of the present invention, in the rolling bearing according to any one of the first to fourth aspects, the lubricant supply member is integrated with a core member attached to the seal groove by press fitting. It is characterized in that it is fixed to the outer diameter surface of the inner ring or the inner diameter surface of the outer ring through the core material.
Furthermore, according to a seventh aspect of the present invention, in the rolling bearing according to any one of the first to sixth aspects, a crown cage is provided, and the crown cage is directed The lubricant supply member is disposed on the side.
Furthermore, according to an eighth aspect of the present invention, in the rolling bearing according to any one of the first to seventh aspects, the groove bearing is a deep groove ball bearing or a thrust angular contact ball bearing.
