Abstract
The invention relates to a hollow shafting particle damper, which is used for comprehensively controlling hollow shafting vibrations. The hollow shafting particle damper comprises two identical semi-cylindrical damping units and a positioning device, wherein the positioning device is positioned between the two semi-cylindrical damping units and is used for fixing the two semi-cylindrical damping units in a hollow shaft. The damper can effectively control the torsional vibration, transverse vibration and longitudinal vibration of a hollow shafting, and is a comprehensive control device for the vibration of the hollow hafting in three directions. The damper is arranged in the hollow shafting so as to effectively make use of the inner space of the shafting and save cost and space.
Description
Technical field
The present invention relates to a kind of hollow shafting damper, belong to the damping vibration attenuation technical field, relate in particular to hollow shafting three-way vibration control damper.
Background technique
The axle of the transmission system of large corporation such as boats and ships, generator set ties up to and is easy to generate vibration in the work, and its vibration mode is multidirectional, promptly has torsional vibration, extensional vibration and transverse vibration simultaneously.It is more that people often pay close attention to torsional vibration under study for action, studied multiple torque-vibration damper, comprises various pendulum-type dampers; Viscosity liquid formula damper and magnetic rheological liquid damper; The damping device that its transverse vibration of control is also arranged simultaneously as the described Shaft damper of patent CN 1620563A, then seldom relates to the damping device of its extensional vibration; And be that various vibration control apparatus all is the branch research of coming to axle at present, strengthen research cost and need take bigger space.Simultaneously, most dampers take an external space, are that arrangement space has certain requirement to axle, cause the inconvenience of the design of axle system, work.
Summary of the invention
The present invention is in order to remedy the deficiency of hollow shafting vibration damper; A kind of novel hollow shafting three-way vibration control damper is provided; This damper can be controlled the three-way vibration of hollow shafting simultaneously, can control torsional vibration, transverse vibration and the extensional vibration of hollow shafting simultaneously.
A kind of hollow shafting particle damper is used for controlling simultaneously torsional vibration, extensional vibration and the transverse vibration of hollow shafting, it is characterized in that:
It comprises two identical semicircle tubular damping units and between two semicircle tubular damping units, makes them be fixed on the positioning device in the hollow shafting;
Above-mentioned semicircle tubular damping unit comprises a semicircular cylinder outer wall, semicircular cylinder inwall, pair of inner wall plate, a pair of semi-round ring shape side plate that above-mentioned semicircular cylinder outer wall is connected with the semicircular cylinder inwall, and above-mentioned semi-round ring shape side plate is left semicircle ring side plate and right semi-circle ring side plate; Above-mentioned left semicircle ring side plate and right semi-circle ring side plate are filled with the damping particle through along circumferentially being distributed in its inboard cushion cap thin-wall steel tube being installed in the thin-wall steel tube;
Above-mentioned positioning device is by screw rod, and be installed on successively left nut, a left side on the screw rod push away pull out, the right side pushes away and pulls out, right nut is formed; The semicircular cylinder inwall of above-mentioned semicircle tubular damping unit have push away with a left side pull out, the right side pushes away and pulls out the round platform cross section that cooperates.
Because the damping particle is through the caused by relative motion damping function between intergranular and particle and container wall; When hollow shafting produces vibration (no matter vibration mode be torsional vibration, transverse vibration or extensional vibration also or its coupled vibrations form); The vibration of hollow shafting can drive granule damper and vibrate thereupon; Collide and friction thereby make between the damping particle in the damper and constantly produce between damping particle and the thin-wall steel tube tube wall; Through the energy of these collisions and the continuous consumption systems that rubs, reach the effect of vibration damping.
Damper of the present invention places the inside of hollow shafting, makes full use of the hollow shafting volume inside, has practiced thrift very large space with respect to the damper of other form.Because cushion cap evenly arranges along the circumferencial direction of damper biside plate, thereby the thin-wall steel tube that has guaranteed to be installed on the cushion cap is symmetrically distributed along the axis of damper, has effectively controlled the Influence from Eccentric that the damping particle causes system when motion.

Embodiment
Structural representation Fig. 1,2 and 3 by damper can know: semicircular cylinder outer wall 2, semicircular cylinder inwall 4 (respectively clipping a round platform by the hollow cylinder two ends forms), the circumferential equally distributed cushion cap 5 of inside panel 3 and edge are all through being bolted on the side plate 1; it is fixing that cushion cap 5 is all inserted at thin-wall steel tube 6 two ends, and damping particle 7 is filled in the thin-wall steel tube 6 with certain fill factor.The two halves of damper are inserted in the cavity of hollow shafting relatively; And push away through nut 9,10 pairs of screw rods and to pull out 8 and apply axial pre tightening force; Make to push away and pull out 8 pairs of inner cores 4 and apply radial force it is strutted the inwall of being close to hollow shaft, thereby realize the location of damper in hollow shaft.
When vibration takes place in hollow shafting; Constantly bump and rub between the damping particle and between the tube wall of damping particle and thin-wall steel tube 6; Come the consumption systems energy through these collisions and friction; But so, thereby reach the purpose of vibration damping for the equal dissipation energy of torsional vibration, transverse vibration and the extensional vibration damping particle of hollow shafting.From dynamically balanced consideration, damping is particles filled in pressing the even thin-wall steel tube of arranging 6 of circumferencial direction, thus reduced the Influence from Eccentric of bringing by the damping particle.
The size of thin-wall steel tube and quantity can be selected according to concrete requirement.The damping particle that is filled in the thin-wall steel tube can be a metal granule, ceramic particle or viscoelastic material particle and other non-metallic particle, and the material of particle, shape and size can be selected according to concrete requirement.
