CENTRALIZED LUBRICATING DEVICE

PURPOSE:To automatize control of a supply amount of oil by detecting a physical quantity generated by a supplied object, judging this detected value for whether it is in a proper region of displaying an ordinary condition of the supplied object or in a correction region of displaying an extraordinary condition, and adjusting a preset supply amount of oil in the case of the detected value in the correction region. CONSTITUTION:In a controller 9, an oil supply command is fed to transceiving stations 7Z1 to 7Zn through a transmission line 8. Then for instance, in the transceiving station 7Z1, based on this command, the oil supply command is output to a pump 4Z1 to start supplying oil. The controller 9, fetching a detection signal of a flow meter 11 from the transceiver 7Z1, judges whether a preset supply amount of oil is supplied or not to a bearing 1Z1. Thereafter, the controller 9 fetches a detecting temperature of a temperature sensor 12 compared with a temperature at ordinary time, to judge a temperature of the bearing 1Z1 for whether in a normal region or in a correction region. At correction region time, based on a difference between the detection temperature and the temperature at normal time, the supply amount of oil is corrected.
