Description
Technical field
The utility model relates to a kind of permanent-magnet linear two way damper.
Background technique
Damper is the device of the resistance providing motion, depletion kinergety.Utilize damper to carry out energy-absorbing damping to be widely used in space flight, aviation, military project, automobile and other industries.After nineteen seventies, people start step by step these technology to be converted in the structural engineerings such as building, bridge, railway, and its development is very rapid.Particularly have five more than ten years history hydraulic pressure viscous damper, the U.S. by structural engineering circle accept before, experienced by a great many of experiments, close scrutiny, proves repeatedly, particularly earthquake test lengthy procedure.
At present, a few class class is broadly divided into according to output damping force mode different China damper: spring-damper, hydraulic damper, viscous damper etc.Spring-damper structure is simple, but spring-damper can change the natural frequency of institute's mounting mechanism and the life-span of spring shorter so inconvenience works long hours again, the place being not easy to change uses.Hydraulic damper complex structure, needs a set of hydraulic system, and hydraulic medium may occur to leak so can not use in a lot of occasion.Viscous damper stable performance, energy dissipation capacity is strong, can provide higher additional damping to structure, and the natural frequency of not change structure, but its damping force exported at different temperature changes, and manufacturing is more difficult, expensive, and viscous liquid is easily leaked, befouling environment.Traditional linear damper is generally that the restoring force by recovering original state after flow of metal provides damping torque, can cause getting rusty and aging corrosion etc. of deformable metal, thus reduce the life-span of self when air weighs high humidity.
Model utility content
The purpose of this utility model is the defect overcoming at present existing damper on the market, provides a kind of permanent-magnet linear two way damper.
In order to achieve the above object, design of the present utility model is:
The utility model mainly adopts the repulsion magnetic force between permanent magnet to provide a power of prolonging axis, a dynamic magnet ring is connected on main shaft by magnetic shield cylinder, a magnetostatic ring is connected on end cap by magnetic shield cylinder, when without applied external force, two ends magnet ring distance quite, can keep steady state.When there being external force left to act on main shaft, main shaft is moved to the left and drives and is moved to the left every insulator cylinder and dynamic magnet ring, and right-hand member two magnet ring relative distances become large, and left end two magnet ring distances reduce relatively.Now right-hand member two magnet ring magnetic force reduce, and left end two magnet ring magnetic force increase, thus to main shaft generally, have a repulsion to the right, stop main shaft to be moved to the left.Now suffered on main shaft repulsion is exported by main shaft, and it is exactly the repulsion that linear damper exports.
Conceive according to above-mentioned model utility, the utility model adopts following technical proposals:
A kind of permanent-magnet linear two way damper, comprises and connects axle head, main shaft, end cap, quiet every magnetic magnetic support, magnetostatic ring, screw, nut, packing ring, dynamic magnet ring, dynamic every magnetic magnetic support, set screw nut and magnetic shield cylinder; Described dynamic magnet ring, dynamic be connected on main shaft every magnetic magnetic support by screw, nut, packing ring; Described magnetostatic ring, quietly to be connected together by screw every magnetic magnetic support, two groups quiet is connected to the both sides of magnetic shield cylinder every magnetic magnetic support by interference fit; Two end caps are arranged on the two ends of magnetic shield cylinder, and described connection axle head and main shaft are threaded connection, and to be exported by repulsion for being connected with the external world by main shaft; Described set screw nut and magnetic shield cylinder are threaded connection; Described magnetic shield cylinder and quiet between magnetic magnetic support and main shaft and magnetostatic ring, quietly have gap between magnetic magnetic support, all can not mutually touch in movement process.
Compared with prior art, the utility model has following substantive distinguishing features and advantage:
The sensitivity of the utility model damper to ambient temperature is less, and especially when high temperature and low temperature, the damping force of output is more or less the same.

Fig. 2 is stereogram of the present utility model.
Embodiment
With specific embodiment, the utility model is further described below:
As depicted in figs. 1 and 2, a kind of permanent-magnet linear two way damper, comprises and connects axle head 1, main shaft 2, end cap 3, quiet every magnetic magnetic support 4, magnetostatic ring 5, screw 6, nut 7, packing ring 8, dynamic magnet ring 9, dynamic every magnetic magnetic support 10, set screw nut 11 and magnetic shield cylinder 12; Described dynamic magnet ring 9, dynamic be connected on main shaft 2 every magnetic magnetic support 10 by screw 6, nut 7, packing ring 8; Described magnetostatic ring 5, quietly to be connected together by screw 6 every magnetic magnetic support 4, two groups quiet is connected to the both sides of magnetic shield cylinder 12 every magnetic magnetic support 4 by interference fit; Two end caps 3 are arranged on the two ends of magnetic shield cylinder 12, and described connection axle head 1 and main shaft 2 are threaded connection, and to be exported by repulsion for being connected with the external world by main shaft 2; Described set screw nut 11 is threaded connection with magnetic shield cylinder 12; Described magnetic shield cylinder 12 and quiet between magnetic magnetic support 4 and main shaft 2 and magnetostatic ring 5, quietly have gap between magnetic magnetic support 4, all can not mutually touch in movement process.
Working procedure of the present utility model is as follows:
When applied external force acts on main shaft 2, main shaft 2 drives and dynamic prolong axis together every magnetic magnetic support 10 and dynamic magnet ring 9 and move, this damper is two-way, when if main shaft 2 is subject to active force left, main shaft 2 is moved to the left and drives and is moved to the left every insulator cylinder 12 and dynamic magnet ring 9, right-hand member two magnet ring relative distances become large, and left end two magnet ring distances reduce relatively.Now right-hand member two magnet ring magnetic force reduce, and left end two magnet ring magnetic force increase, thus to main shaft 2 generally, have a repulsion to the right, stop main shaft 2 to be moved to the left.Now suffered on main shaft 2 repulsion is exported by main shaft 2, i.e. the repulsion that exports of linear damper.When main shaft 2 is subject to active force to the right, it is analyzed with similar time left.
