Abstract:
The bearing life prediction device includes a pressure measuring unit that measures the pressure applied to a front bearing, a coolant pressure measuring unit that measures the pressure of a coolant liquid, a detecting unit that measures or predicts the rotation number and the temperature, a storage unit that stores model information and motor specification information in correlation, a specifying unit that inputs or selects the model information, and a bearing life prediction unit that predicts the life of the bearings on the basis of the motor specification information including the specification information of the bearings stored in the storage unit in correlation with the model information input or selected by the specifying unit, the pressure information of the coolant liquid, the pressure information applied to the front bearing, the rotation number information of the motor, and the temperature information of the bearings.

Claim (Index 1):
A bearing life prediction device that predicts a life of a pair of bearings that rotatably supports a rotating shaft portion of a motor used in a machine tool, through which a coolant liquid can be passed, the rotating shaft portion being connected to a coolant delivery unit via a rotary joint at one end in a rotating shaft direction and connected to a spindle capable of discharging the coolant liquid via a connecting portion at the other end, the bearing life prediction device comprising:\n a pressure measuring unit that measures a pressure in the rotating shaft direction applied to a front bearing disposed on the other end side in the rotating shaft directon of the pair of bearings; a coolant pressure measuring unit that measures a pressure of the coolant liquid; a motor state detecting unit that measures or predicts a rotation number of the motor and a temperature of the pair of bearings; a motor information storage unit that stores model information for specifying respective motor models and motor specification information which is specification information of each motor model and includes at least specification information of the pair of bearings in correlation; a motor model specifying unit that inputs or selects model information for specifying the motor model; and a bearing life prediction unit that predicts the life of the pair of bearings on the basis of the motor specification information including the specification information of the pair of bearings stored in the motor information storage unit in correlation with the model information input or selected by the motor model specifying unit, pressure information of the coolant liquid measured by the coolant pressure measuring unit, pressure information in the rotating shaft direction applied to the front bearing measured by the pressure measuring unit, rotation number information of the motor measured or predicted by the motor state detecting unit, and temperature information of the pair of bearings.
