Embodiment
Below in conjunction with drawings and Examples unidirectional rotary buffer of the present utility model is done to describe in detail:
Fig. 1, Fig. 2, Fig. 3 show the overall structure situation of the unidirectional rotary buffer of the utility model respectively in the mode of sectional view, sectional drawing, enlarged view.
As seen from the figure, the utility model has adopted and prior art part identical construction, and its formation comprises running shaft 1 and main body 3; The inwall of described main body 3 is provided with symmetrical gusset 8, one end of described running shaft 1 is provided with and connects handle 9, an other end of described running shaft 1 inserts main body 3, the external diameter that described running shaft 1 inserts main body 3 parts is set to footpath curved surface 12 mostly, it is in rotational direction ascending that the radius of described most footpaths curved surface 12 is positioned at the part of pivot region, described most footpaths curved surface 12 is provided with symmetrical blading 7, in the logical square hole 13 of described symmetrical blading 7 switching value valve metal film 4 is installed; The axle journal place of described running shaft 1 is provided with the sealing cover 2 that agrees with mutually with the opening end of described main body 3, adopt 0 V-shaped ring 5 to realize sealing between the axle journal of described sealing cover 2 and running shaft 1, adopt sealing gasket 6 to realize sealing between the boss of described sealing cover 2 and running shaft 1, make and form the Seal cage that to fill damper fluid between described main body 3 and the running shaft 1, described Seal cage is divided into hyperbaric chamber 10 and low-pressure cavity 11 by the running shaft 1 that is provided with symmetrical blading 7, the damper fluid that flows between described hyperbaric chamber 10 and low-pressure cavity 11 realizes the damping function to described running shaft 1, and connection handle 9 output torques by described running shaft 1.
Fig. 4 (a) and Fig. 4 (b) show in the mode of plan view and left view respectively and are arranged on the curved surface 12 of described most footpaths the structure shape of a blade in the symmetrical blading 7.Mark 13 among the figure is the logical square holes that are used to place switching value valve metal film 4, and the mark 14 among the figure is oil pressure runner mouths of being opened on described logical square hole 13 sidewalls.The width dimensions and the prior art of described logical square hole 13 are all 0.55mm, and the length dimension of described logical square hole 13 is also same as the prior art.
Fig. 5 (a) and Fig. 5 (b) show the structure shape that is arranged on the switching value valve metal film 4 in the described logical square hole 13 in the mode of plan view and left view respectively.What wherein Fig. 5 (b) illustrated is the thickness of switching value valve metal film 4.The realization of the utility model technique effect is achieved by the thickness that changes described switching value valve metal film 4.In order to reach the purpose of adjusting the small output quantity of damper fluid with the switching value valve metal film 4 of different-thickness reliably, the utility model is arranged on the serial thickness size of described switching value valve metal film 4 in 0.1～0.55mm scope, in concrete enforcement, can select the thickness size of numerical value such as 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.4mm, 0.5mm or 0.55mm respectively according to the requirement of applying working condition as described switching value valve metal film 4.
Working principle of the present utility model is such: when rotating with the connection handle 9 driven rotary axles 1 of external force by described running shaft 1, damper fluid in the described hyperbaric chamber 10 by described running shaft 1 external diameter and described main body 3 on the formed runner in slit between the symmetrical gusset 8 top cambered surfaces arrive described low-pressure cavity 11, because the external diameter of most footpaths curved surface 12 is ascending variations gradually on the described running shaft 1, so, rotation along with running shaft 1, the slit that forms aforementioned runner will be descending gradually, thereby the flow velocity of restriction damper fluid is more and more slower, until realizing the increasing damping function of described running shaft 1; When producing interference fit between the top cambered surface of symmetrical gusset 8 on the external diameter of described running shaft 1 and the described main body 3, the damper fluid of passing through from the slit of aforementioned formation runner reduces gradually, the frictional force that produces between the cambered surface on the external diameter of described in addition running shaft 1 and described symmetrical gusset 8 tops, make the moment of torsion of described running shaft 1 reach maximum gradually, at this moment, because the slit of aforementioned formation runner has been in closed state, the oil pressure runner mouth 14 that damper fluid in the described hyperbaric chamber 10 can only be opened by logical square hole 13 sidewalls on the described symmetrical blading 7 and be placed on switching value valve metal film 4 in the described logical square hole 13 and the sideshake between the described logical square hole 13 flows to two axial ends of described blade 7 and enters in the described low-pressure cavity 11, the moment of torsion maximum that makes running shaft 1 output, thus maximum cushioning effect obtained.
Because the utility model selects to have disposed the switching value valve metal film 4 of different-thickness in described logical square hole 13, form described logical square hole 13 and be placed on the different gap amount between the switching value valve metal film 4 in the described logical square hole 13, so, can on microcosmic, reach the purpose of control damper fluid flow, and produce different moments of torsion in a big way thus.
Because the utility model is adjusted the through-current capacity of damper fluid in symmetrical blading 7 by changing the volume of described switching value valve metal film 4 in described logical square hole 13, so, need not make the buffer of different moments of torsion with the method for too much selection different viscosities damper fluid.
The utility model changes the design of described switching value valve metal film 4 volume in described logical square hole 13, can make unidirectional rotary buffer under little moment of torsion working condition requirement, also can use the damper fluid of viscosity higher, thereby adjust the through-current capacity of damper fluid by described logical square hole 13 and the different gap amount between the switching value valve metal film 4 in the described logical square hole 13 of being placed on, effectively avoided prior art to use the unavoidable leakage phenomenon of low viscosity damper fluid.
Based on above set-up mode, the characteristics that the utility model is better than prior art are: guaranteed that effectively buffer after using the long period (or more number of times), still can export the moment of torsion of balance and stability reliably; On the basis of this technological scheme, can produce the buffer that can guarantee the balance and stability output torque easily and satisfy the buffer that high pulling torque more requires.
Below in conjunction with the accompanying drawings and embodiments the utility model is schematically described, this description does not have restricted, and shown in the drawings also is embodiment of the present utility model, and therefore, actual enforcement of the present utility model is not limited thereto.Those of ordinary skill in the art should be understood that, in actual enforcement of the present utility model, shape and set-up mode to switching value valve metal film in logical square hole and the logical square hole on the symmetrical blading in the described unidirectional rotary buffer all may have some changes, and under enlightenment of the present utility model, other staff also may make similar Design.Special needs to be pointed out is that only otherwise breaking away from the utility model changes the design aim of damper fluid runner size by the varied in thickness of switching value valve metal film, all conspicuous changes all should belong to protection domain of the present utility model.
