摘要： PURPOSE:To constitute a segment so that the same can bear a heavy load in a radial direction and replacement of a cam plate resulting from a change of dimensions of a belt can be performed swiftly, by bearing shaping reaction force by the cam plate other than the one for expansion or contraction driving of the segment. CONSTITUTION:At the time of holding of a belt, a cam plate 10 is revolved, a supporting bar 2 is moved inside in a radial direction and the belt is held by performing contraction of the diameter of a segment. At the time of locking (against reaction force expanding the diameter), a disc plate 13 is revolved and a cam part 19 of a cam plate 15 is fitted to a position I. In this instance, force which acts upon the segment and is apt to expand the diameter is born by the cam part 19 of the cam plate 15 through a cam roller 9 and force which is apt to revolve against the cam plate 10 is not generated. At the time of release of the locking, the disc plate 13 is revolved and the cam part of the cam plate 15 is removed from the cam roller 9 at a position II. At the time of the release of the belt, the cam plate 10 is revolved, the supporting bar is moved outside in a radial direction and the diameter of the segment 1 is expanded.

摘要： PURPOSE:To eliminate a clearance between the inner diameter of a spacer and the projection of a spindle in heating to correct the concentricity and facilitate the accuracy control by loosely fitting the projection having large rate of expansion at the end face of a rotary shaft into a hole in the rotary center of a rotor and mounting radially expansively a rotor on a flange of the rotary shaft. CONSTITUTION:In a cylindrical hole 11a at the center of a side plate 11 of a drum 1 is cold mounted a cylindrical spacer 13 having coefficient of thermal expansion larger than that of the side plate 11. The inside of the spacer 13 engages a projection 14 of a spindle 4 to fasten the drum 1 to the spindle 4 with bolts 15. The inner diameter of the spacer 13 and the outer diameter of the projection 14 on the spindle 4 are spaced from each other in the normal temperature. Since the material of the spacer 13 has the coefficient of thermal expansion larger than that of the drum side plate 11 and spindle 4, the clearance present in the normal temperature between the spacer 13 and the projection 14 is offset in heating by the difference between the coefficients of thermal expansion of the spacer 13, drum side plate 11 and spindle projection 12 in the rise of temperature to provide concentricity between the spacer and spindle.
