摘要： PROBLEM TO BE SOLVED: To achieve a measurement device capable of simultaneously measuring autorotation of a roller, revolution of the roller, and a load exerted on a holder by the roller.SOLUTION: A measurement device 2 for roller bearing motion characteristics can measure autorotation angular displacement (θr) of a roller 103 by measuring rotation of a multipolar magnet disk 110 rotating coaxially with an autorotation shaft of the roller of an autorotation measurement object by a hall element 112 fixed to a holder 104 of a target bearing 100. A pulse groove part 130 is provided in a circumferential direction on the holder 104, and rotation of the holder, that is, revolution angular displacement (θh) of the roller 103 can be measured by a gap sensor 132 fixed to a stationary system. Moreover, a first small type load cell 116 and a second small type load cell 117 for detecting load applied by the roller are attached on the inside of a pocket face accommodating the roller 103 of a load detection object, and thus loads (Wh1, Wh2) applied to the holder by the roller can be measured.

摘要： PROBLEM TO BE SOLVED: To provide a test device capable of simulating relative movement between a roller of an actual roller bearing and a retainer.SOLUTION: A sample roller 14 is fixed to a main shaft 10 rotated by a motor 4 to cause the sample roller 14 to be rotated (auto-rotated). To the rolling surface of the sample roller 14, a sample holder 26 can be pressed by a load-variable load loading device 20. A test control computer 100 preliminarily stores load pattern data 152 based on actual measurement, and outputs a load control signal (Pac) to the load loading device 20 so as to attain load fluctuation, defined by the load pattern data 152, in a period based on a revolution period equivalent to the number of auto-rotations of the sample roller 14.
