<P>PROBLEM TO BE SOLVED: To provide a method and a device for testing a relationship between an axial load applied on a rotary shaft such as a main spindle 2 after the start of use and the output signal of a sensor unit 7 disposed to obtain the axial load. <P>SOLUTION: Between the tip surface of the main spindle 2 and a holding member 13 disposed in a part facing the tip surface, a load measuring device 14, a holding case 15, and a load transmission shaft 16 rotatably supported on the holding case 15 by a double row bearing unit 19 are arranged. In a state where the main spindle 2 is rotated while the end of the main spindle 2 is pressed to the load transmission shaft 16, the output signal of the sensor unit 7 is obtained. Then, on the basis of a relationship between the output signal and the measurement value of the load measuring device 14, appropriateness of a relationship between the output signal and the axial load is determined. <P>COPYRIGHT: (C)2012,JPO&INPIT |
