Title:
WHEEL, TRAVEL DEVICE, X-RAY TESTING SYSTEM, AND X-RAY TESTING METHOD
Document Type and Number:
Japanese Patent JP2017001505
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a wheel that suppresses slippage with respect to a steel pipe.SOLUTION: A wheel 20 includes a first disc part 25 that generates magnetic force, and a second disc part 35 made of an elastic material which is formed in a larger diameter than the diameter of the first disc part, is arranged side by side with the first disc part in an axis C direction of the first disc part, and is arranged coaxially with the first disc part. A static friction coefficient in an outer peripheral surface 37a of the second disc part is larger than the static friction coefficient in an outer peripheral surface 27d of the first disc part, and elasticity modulus of the second disc plate is smaller than the elasticity modulus of the first disc part.SELECTED DRAWING: Figure 4
