Title:
摩擦係数測定装置および摩擦係数測定方法
Document Type and Number:
Japanese Patent JP7190231
Kind Code:
B2
Abstract:
To provide a friction coefficient measuring device and a friction coefficient measuring method with which it is possible to realize, by one drive source, a state in which a test piece does a circular motion and a second state in which it does a linear motion, and measure a friction coefficient in the respective motion.SOLUTION: The friction coefficient measuring device comprises: a base plate 10 in which a first open hole 14 is formed; an X-axis table 21 in which a second open hole 24 is formed; a Y-axis table 31 that moves to the X-axis table 21; a Z-axis drive part 40; a motor 50 provided downward of the first open hole 14; and a crank shaft 60 that connects the output shaft 51 of the motor 50 to the reverse side of the Y-axis table 31 via the first and second open holes 14, 24. An upper end 61 of the crank shaft 60 is eccentric to the output shaft 51, the X-axis table 21 has an exposed region G that is exposed from the Y-axis table 31, and the Z-axis drive part 40 presses a first test piece 71 against a second test piece 72 at positions above the Y-axis table 31 and above the exposed region G.SELECTED DRAWING: Figure 1
