A flexible roller device of variable rate for rotary machine centering

The utility model relates to a flexible roller device of the variable rate of rotary machine centering, including base, gyro wheel, roller shaft, blend stop and gyro wheel support, the roller shaft passes through that the blend stop is detachable to be fixed on the gyro wheel support, also is equipped with elastic mechanism, adjustment mechanism and fixed establishment, the elastic mechanism includes elastic component and locating shaft, and locating shaft welded fastening is at gyro wheel support lateral part, adjustment mechanism locates guiding orientation bolt and a lock nut, an adjusting nut, the 2nd adjusting nut and the 2nd lock nut on adjusting the backup pad including regulation backup pad, at least two symmetry. The roller device have with low costs, the size is little, conveniently install and remove advantage such as maintenance, can produce the coefficient of elasticity characteristic that corresponds different rigidity with the displacement to the difference, the flexible compensation is carried out to radial displacement characteristic that the adaptation arouses because of track out -of -roundness and work platform dynamic offset etc. Simultaneously can arouse that the race way diameter changes and the displacement that produces is carried out the rigidity and is compensated to the temperature variation.
