摘要： A first seal member includes a double-structure bellows in corrugated form, and vibration control device provided on the outside of the bellows such as to cover part of the bellows. A flat portion that is not in corrugated form is provided in part of the bellows. The vibration control device is provided in circumferential direction on an outer surface of the flat portion, and made up of a ring-shaped rib having a plurality of holes in a circumferential direction and weights inserted in the holes provided in a wall of rib. Natural frequency is adjusted by adjusting the number of weights, thereby preventing resonance between the natural frequency of the first seal member and the rotational frequency of rotor from occurring.

摘要： A sealing mechanism includes a pair of space forming rings which face each other and are configured for surrounding a shaft body, an outer bellows-joint having one end connected to an outer periphery of one of the space forming rings and another end connected to an outer periphery of the other of the space forming rings, and an inner bellows-joint having one end connected to an inner periphery of one of the space forming rings and another end connected to an inner periphery of the other of the space forming rings. Each of the inner bellows-joint and the outer bellows-joint is a corrugated plate. The space forming rings space the inner bellows-joint and the outer bellows-joint apart from each other such that the inner bellows-joint and the outer bellows-joint do not come in contact with each other.

摘要： Spindle inclination detectors (41A, 41B) are equipped in columns (32A, 32B) of a portal bridge (24) of a machine tool (21). Each spindle inclination detector includes: a string (43) which hangs vertically with an upper end fixed to the column (reinforcement (32b)) and a lower end attached to a weight (45); a gap sensor (44) which is attached to the string to measure a distance to a front face plate (32a) of the column; and an oil damper (46). Moreover, a spindle inclination correction controller provided to the machine tool controls a Peltier device (42A, 42B) attached to a rear face plate (32d) of the column, on a basis of an average distance measured by the gap sensor, and thus corrects an inclination of a spindle (28) due to the thermal deformation of the column by correcting thermal deformation of the column.
