Abstract: A cutting saw apparatus equipped with a non-contact lubrication and vibrating reduction device is provided to reduce the side deformation of a cutting saw resulting from the pressure exerted on two opposite side surfaces of the cutting saw, vibration, and noise caused by the side deformation. A cutting saw apparatus includes a non-contact lubrication and vibrating reduction device. The non-contact lubrication and vibrating reduction device includes a plurality of hydrostatic thrust bearings(20), a fluid supply unit(21), and a fluid supply horse(22). The hydrostatic thrust bearing includes an introduction passage, an orifice passage, an internal passage. The hydrostatic thrust bearing is installed at two opposite side surface of a safety cover(10) to inject a high-pressure fluid to two opposite side surfaces of a cutting saw provided inside the safety cover. The fluid supply unit is connected to a driving shaft(4) of a driving motor to supply the high-pressure working fluid to the hydrostatic thrust bearing by the driving motor. The horse couples the hydrostatic thrust bearing to the fluid supply unit to allow the high-pressure fluid to flow through the horse.

Abstract: A labyrinth seal is provided to efficiently control the axial leakage of working fluid according to the target leakage and the rotation state of a rotation axis through active-control of the clearance between the labyrinth seal and the rotation axis by an actuator. A labyrinth seal comprises a sealing disk(111) which is formed on a rotation axis to be extended in the radial direction of the rotation axis, a seal ring(120) which is located apart from the sealing disk while facing the sealing disk, an actuator(130) which controls the gap between the seal ring and the sealing disk by moving the seal ring, and a controller(150) which controls the operation of the actuator.

Abstract: A high pressure floating ring seal supported with a bump foil is provided to solve a rubbing problem of an axis and the seal and improve stability by the floating circular seal having a supporting bump. In a high pressure floating ring seal supported with a bump foil, a clamping nut(100) is installed around a rotary axis(400) of a cylindrical shape. A floating circular ring(300) moves between the clamping nut and the rotary axis in the direction of an axis, a radius and a circumference. A bump(500) supports the floating circular ring by being installed between the clamping nut and the floating circular ring. A supporting ring supports the clamping nut, the floating circular ring, and the bump at the side.
