SHAFT ABNORMAL-TEMPERATURE ALARM DEVICE OF FACILITY HAVING MULTIPLE GROUPS OF ROTARY BODY

摘要

PROBLEM TO BE SOLVED: To detect abnormal temperatures of shafts of rollers as rotary bodies.;SOLUTION: Rotating facilities, arranged parallely in multiple groups in a longitudinal direction, which are constituted of a shaft 2 and a rotating body 1 pivotally supported at the outside of the shaft with the shaft as a rotation center, employ constitutions where a heat sensing switch B that is turned on accompanying abnormal temperature rise of the pivotally supported part is provided at an end part of the shaft, a transmitter D that is electrified from a power source C and transmits accompanying the turning-ON of the heat sensing switch is provided in the shaft, and further plural rows between the heads and the tails of the multiple groups of parallel rotating facilities are sequentially divided into groups, the transmitter of the rotating body of each group is connected to a side wall of a device, and each side wall of the device is connected to a central control panel.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2017,JPO&INPIT
