Title: (DE) ALARMSYSTEM.
(EN) ALARM.
(FR) SYSTEME D'AVERTISSEMENT.
Abstract: front page image
(EN) The present invention relates to an alarm system suitable for use in warning of overheating in rotatable bearings (4) having first and second bearing portions. The alarm system comprises an alarm signal generator means having a thermally activated engagement element (8) on a first bearing portion or body (6) connected thereto. The element (8) is in thermal connection with the bearing (4) and is formed and arranged so as to be driven from a first primed retracted position into a second deployed extended alarm position upon reaching a predetermined temperature. In the alarm position the element (8) contacts an engaging portion (12) on the second bearing portion so as to produce a distinctive alarm signal indicating that said bearing (4) has exceeded the predetermined temperature.
(FR) Système d'avertissement apte à donner l'alerte lorsqu'un palier rotatif (4) comportant une première et une seconde parties porteuses risque de surchauffer. Ledit système comporte un générateur de signal d'alarme possédant un élément de contact à actionnement thermique (8) placé sur une première partie porteuse ou un corps (6) relié(e) à celui-ci. L'élément (8) se trouve en communication par voie thermique avec le palier (4) et est conçu pour pouvoir se déplacer entre une première position dans laquelle il est escamoté et armé, et une seconde position d'avertissement dans laquelle il est sorti, cela lorsqu'un seuil de température prédéterminé est dépassé. Dans la position d'avertissement, l'élément (8) se trouve en contact avec une partie de contact (12) de la seconde partie porteuse de manière à produire un signal d'alarme facilement reconnaissable destiné à indiquer que la température du palier (4) a dépassé le seuil de température prédéterminé.
