<p><P>PROBLEM TO BE SOLVED: To provide a bearing testing device capable of precisely reproducing the white exfoliation phenomenon of a bearing in a market, in a short time, and capable of optionally reproducing the white exfoliation of a rolling contact surface or a rolling element of the bearing. <P>SOLUTION: The bearing testing device includes a test bearing 1, constituted of an inner ring, an outer ring and an rolling element; a rotary shaft 3, penetrated and fixed into the inner ring of the test bearing; a pulley 11 attached to one end of the rotary shaft; a support bearing 2 which is located in the direction opposite to the pulley, with the test bearing in between, and into which the rotary shaft is penetrated and fixed; a housing 5 fixing the outer ring of the test bearing and supported by a base via an insulator; a rotation-driving means; an endless belt 12 for transmitting the torque of the rotation driving means to the pulley; and as an external power source, a static electricity generator 10. A projecting part 3a is provided at the rotation center of the end of the rotary shaft, and one of the pair of terminals of the static electricity generator is connected to the outer ring 1g of the test bearing, while the other is slidingly contacted with the projecting part. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
