Title (EN) BEARING WITH MEASUREMENT FUNCTION
(FR) PALIER AVEC FONCTION DE MESURE
(JA) 計測機能付き軸受
Abstract:
(EN) In order to determine information about the generation of heat in a bearing (10) in a simple manner, a bearing (10) includes an outer ring (12) secured to a securing member, and an inner ring (11) provided on the inside of the outer ring (12) and secured to a shaft that rotates in the circumferential direction relative to the securing member. A thermal flow sensor (14) is coated onto a securing-side surface that includes the outer ring (12), and generates a thermoelectric force including information about frictional heat generated with the rotation of the shaft.
(FR) Afin de déterminer de manière simple des informations concernant la génération de chaleur dans un palier (10), l'invention concerne un palier (10) comprenant un anneau externe (12) fixé à un élément de fixation, et un anneau interne (11) disposé à l'intérieur de l'anneau externe (12) et fixé à un arbre qui tourne dans la direction circonférentielle par rapport à l'élément de fixation. Un capteur de flux thermique (14) est appliqué sur une surface côté fixation qui comprend l'anneau externe (12), et génère une force thermoélectrique comprenant des informations concernant la chaleur de friction générée avec la rotation de l'arbre.
(JA) 軸受(10)における発熱の情報を、簡潔に把握する。軸受(10)は、固定部材に固定された外輪(12)と、この外輪(12)の内側に設けられて、固定部材に対して円周方向に回転する軸に固定された内輪(11)と、を含む。熱流センサ(14)は、外輪(12)を含む固定側の表面にコーティングされて、軸の回転に伴って生じる摩擦熱の情報を含む熱起電力を生成する。
