ABRASION TESTER, ABRASION TEST PIECE, AND ABRASION TEST METHOD

摘要

PROBLEM TO BE SOLVED: To provide an abrasion test piece and an abrasion tester, capable of uniformly setting a surface pressure on an abrasion surface and reliably obtaining data.;SOLUTION: The test piece 11 includes a cylindrical unit 28, and a flange 29. The test piece 12 is disposed opposite to the test piece 11. The flange 29 is radially protruded from the cylindrical unit 28 toward the outside. Key grooves 24 are provided on an outer circumference 32 in the flange 29. A key 22 of a drive 15 is engaged with the key groove 24. A rotational torque is applied to the cylindrical unit 28. The drive 15 slides the test piece 11 toward the test piece 12. Four key grooves 24 are circumferentially disposed and equally spaced in the flange 29. A depth of the key groove 24 is set so as to prevent the rotational torque applied to the flange 29 from affecting a pressing force applied to the cylindrical unit 28.;COPYRIGHT: (C)2011,JPO&INPIT
