Abstract

PURPOSE:To make it possible to reduce friction loss by arranging nonequal rolling elements different in diameter continuously by turns for making small elements function as idlers. CONSTITUTION:Rolling elements 3, 4 of balls or rollers are arranged continuously large one and small one by turns. Arranging in this way, loading load is born only by large elements 3. While, small elements 4 function merely as idler retaining distance between respective large elements and rotate in reverse direction to large elements to help these. Accordingly, force working to idler elements becomes almost of lateral direction, and frictional resistance or the like with inner wall can be neglected so frictional resistance can be reduced.

Description

【発明の詳細な説明】 （イ）産業上の利用分野 この発明は、高負荷高速の回転器機に使われる低損失の
転がり軸受に関するものである。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to a low-loss rolling bearing used in high-load, high-speed rotating equipment.

に逆方向に擦れ合って、摩耗や焼付等の損傷をおこしや
すく、通常、これらを保持器で分離して使用する。(b) Conventional technology Conventionally, in high-speed rolling bearings, when rolling elements such as balls or rollers are arranged in succession, their contact points rub against each other in opposite directions, resulting in damage such as wear and seizure. Usually, these are separated with a cage and used.

しかし、まだ、近来、高負荷高速となるのに従って、案

きた。However, in recent years, as the loads and speeds have become higher, accidents in which the cage itself is damaged due to guiding friction, etc., have been increasing.

視できる。(E) Function By doing this, only the dog element 3 will be responsible for the load. Meanwhile, the small elements 4 simply act as idlers to hold the dog elements together, and rotate in the opposite direction to the dog elements to assist them, as shown by the arrows. Although the drawing emphasizes the difference in size for the purpose of explanation, in reality there only needs to be a slight difference, and at this time, the force applied to the idler element is mostly in the lateral direction, and the force applied to the idler element is mostly in the lateral direction. Frictional resistance etc. can be ignored.
