Description
本発明は、噴射ノズルから潤滑剤を圧縮空気とともに噴射して転がり軸受に潤滑剤を供給する軸受潤滑装置であって、前記噴射ノズルの噴射方向が、前記転がり軸受の転動体の公転方向に向かって傾斜し、前記噴射ノズルが、複数の前記転がり軸受の外輪同士の間に配設される噴射リングに形成されていることを特徴としている。 The present invention is a bearing lubrication device that injects a lubricant together with compressed air from an injection nozzle and supplies the lubricant to a rolling bearing, and the injection direction of the injection nozzle is directed to the revolution direction of a rolling element of the rolling bearing. And the injection nozzle is formed in an injection ring disposed between outer rings of the plurality of rolling bearings .
また、本発明は、前記噴射ノズルの噴射方向は、前記転がり軸受けの中心軸に対して傾斜していることを特徴としている。 Further, the present invention is characterized in that an injection direction of the injection nozzle is inclined with respect to a central axis of the rolling bearing .
