Summary of the invention
The object of the invention is to overcome defect of the prior art and deficiency, a kind of novel turbine slender axles are provided to stablize jacket, these turbine slender axles are stablized jacket and are utilized self distinctive cover plate magnet ring, flywheel magnet ring and electric-controlled hydraulic flexible rod, use magnetic pole principle of same-sex repulsion to control shafting vibration.
Above-mentioned purpose can be realized by following technological means: a kind of turbine slender axles stablize jacket, comprise cover plate and be arranged on the flywheel in cover plate, flywheel is arranged on to be needed on the axle of vibration damping, axle, cover plate and flywheel are coaxially installed, the position of the corresponding flywheel of cover plate internal surface is provided with cover plate magnet ring, flywheel is provided with flywheel magnet ring, the face that flywheel magnet ring is relative with cover plate magnet ring is same pole, and cover plate magnet ring and flywheel magnet ring are built exists gap.
Vibration damping equipment also comprises cooling unit.In the present invention, cooling unit is preferably water cooling plant.Its concrete structure is: this water cooling plant comprises water cooling box, water-cooled outflow tube, water-cooling pipe and water cooled reflux pipe, and wherein water-cooling pipe is arranged in cover plate, and water-cooling pipe is connected with water cooling box with water cooled reflux pipe by water-cooled outflow tube.
Turbine slender axles are stablized jacket and are also comprised regulating mechanism for adjusting cover plate and flywheel relative position.Regulating mechanism comprises the flexible rod support being fixed on cover plate outer surface and the flexible rod be fixed on flexible rod support, and flexible rod carries out control action by electronically controlled hydraulic system.Direction and the plane parallel perpendicular to the axle of cover plate of adjustment, can reach circumference 360 degree.
Preferably, flexible supporter and flexible rod have four groups, are equidistantly arranged on sleeve outer surface and are distributed in same perpendicular in the plane of sleeve axis.
Turbine slender axles are stablized jacket and are also comprised the vibration monitor be fixedly mounted in cover plate, and the signal data of vibration can be sent back monitor control system by vibration monitor.When boats and ships start by vibration monitor monitoring vibration coefficient, when Oscillating Coefficients reaches harm critical value, send a signal to monitor control system, start above-mentioned electro-hydraulic system and cover plate position is finely tuned, realize vibration damping operation automation.
Preferably, in order to reach better damping effect, flywheel has three, coaxial and be parallel to each otherly arranged on sleeve inner.
Usefulness of the present invention is: by regulating four electric-controlled hydraulic flexible rods, the position of fine setting cover plate, due to the principle of magnetic pole two like magnetic poles repel each other, the cover plate magnet ring be arranged in cover plate produces active force by with the flywheel magnet ring be arranged on flywheel, active force passes to axle system by flywheel, due to the impact of circumferential active force when axle ties up to rotation, thus reduce vibration when rotating.This apparatus structure is relatively simple, simple installation.

Embodiment
Below in conjunction with specific embodiment and accompanying drawing, the present invention is described further.
Turbine slender axles as shown in Figure 1 to Figure 3 stablize jacket, and comprise three flywheels 8 be coaxially arranged on ship shaft, cover plate 11, the vibration monitor 3 being arranged on cover plate 11 outer surface, regulating mechanism and water cooling plant, wherein flywheel 8 is arranged on the inside of cover plate 11.The outer surface of flywheel 8 is fixed with flywheel magnet ring 2, and accordingly, the inside of cover plate 11 is provided with cover plate magnet ring 1, there is gap between cover plate magnet ring 1 and flywheel magnet ring 2.
Water cooling plant comprises water cooled reflux pipe 4, water cooling box 5, water-cooled outflow tube 6, water-cooling pipe 7, and water-cooling pipe 7 is looped around the outer surface of cover plate 11 and is connected with water cooling box 5 with water-cooled outflow tube 6 by water cooled reflux pipe 4.
The electric-controlled hydraulic flexible rod 10 that regulating mechanism comprises flexible rod support 9 and is fixed on flexible rod support 9, wherein flexible supporter 9 and flexible rod 10 have four groups, are equidistantly arranged on the outer surface of sleeve 11 and are distributed in same perpendicular in the plane of sleeve axis.
Specific works mode is: as shown in Figure 1, and water cooling box 5 and four electric-controlled hydraulic flexible rods 10 are arranged on the predetermined supporting position of watercraft engine room, and the drive line of boats and ships is inserted in flywheel 8, as shown in Figure 2, have three flywheels 8.When axle system rotates, produce certain vibration, read the reading of vibration monitor 3, when vibration reaches harm critical value, start regulating controller and carry out vibration control.By controlling four electric-controlled hydraulic flexible rods 10, the position of fine setting cover plate 11, direction and the plane parallel perpendicular to marine shafting of adjustment, can reach circumference 360 degree.As shown in Figure 3, because the face that cover plate magnet ring 1 is relative with flywheel magnet ring 2 is same pole, the magnetic action power produced will be applied to axle by flywheel 8 and fasten, axle system rotates flywheel driven 8 and rotates, due to the annular design of flywheel magnet ring 2, in 360 degree of scopes of rotating, all have received the effect of magnetic force, after active force is applied to axle system, effectively can reduce the vibration of axle system.The design of three flywheels 8 in device, it also avoid axle system because of stressed single and cause damage.The vibration monitor 3 be arranged in cover plate 11 can read vibration frequency and intensity in real time, by the feedback of reading, can, so that suitably regulate electric-controlled hydraulic flexible rod 10, make vibration control in the most rational scope.Axle system can produce certain heat when rotating, these heats will be passed on device, as shown in Figure 1, when plant running, cold water is delivered in water-cooling pipe 7 by water-cooled outflow tube 6 by water cooling box 5, the heat in cover plate 11 taken away effectively by water-cooling pipe 7, and then, water is back in water cooling box 5 by water cooled reflux pipe 4, by the mode of water-cooled, make device remain on suitable temperature, the reliability of intensifier, increases the service life.
