摘要： When a finishing operation is performed while rotating a workpiece at a main shaft drive of a machine tool, pulsation occurring in a rotation of the main shaft drive is restricted and the rigidity of a main shaft is increased without increasing the size of a bearing. A rotation-resistance device of a main shaft drive in a machine tool has the following structure in the main shaft drive including a main shaft 4, a rotating body 65, and a driving device 6, the main shaft 4 being supported so as to be rotatable with respect to a frame body 2, the rotating body 65 being secured to an end of the main shaft 4, the driving device 6 rotationally driving the rotating body (65). The rotation-resistance device includes a damping device (10) including a damping member, which is provided at the frame body 2 or the rotating body 65 and which includes a resiliently deformable damping section, a pressing-force applying device 66, which applies a pressing force to the damping member by operating fluid, and a damping surface 32, provided at a side of the frame body 2. The damping device 10 causes the pressing force to act upon the damping section to flex the damping section, so that the damping surface 32 and a sliding surface 33 are pressed against each other, and a rotation resistance that allows rotation is applied to the rotating body 65. A low-friction coefficient member 60 is secured to at least one of the damping surface 32 and the sliding surface 33.

摘要： A rotary table includes a brake mechanism capable of providing a large and sufficient brake force. The brake mechanism includes an inner peripheral surface and outer peripheral surface of a sleeve formed coaxially with an axis of a rotatable table, an outer stationary portion provided to a stationary member rotatably supporting the rotatable table and defining an outer hydraulic chamber, and an inner stationary portion provided to the stationary member, arranged radially inward from the outer stationary portion and defining an inner hydraulic chamber. The outer stationary portion is elastically deformed in a radial direction by expansion of the outer hydraulic chamber to push the outer peripheral surface of the sleeve formed on the rotatable table, while the inner stationary portion is elastically deformed in a radial direction by expansion of the inner hydraulic chamber to push the inner peripheral surface of the sleeve formed on the rotatable table.
