Sleeve 8 is circular ring, material is carbon steel, wall thickness is 3 ~ 5mm, internal diameter is more smaller than feed screw nut 7 smooth cylindrical structure 22 outer diameter D 5, outside the smooth cylindrical structure 22 being mounted on feed screw nut 7 by interference, its two ends contact with boss structure 21 times edges of feed screw nut and bearing 9 respectively, thus are axially carrying out spacing (as shown in Figure 2) bearing 9.
The internal diameter of bearing 9 is slightly less than feed screw nut 7 cylindrical end outer diameter D 5, outside the smooth cylindrical structure 22 being enclosed within feed screw nut by elastic conjunction (as shown in Figure 2).Bearing 9 axially carry out respectively by sleeve 8 and bearing fixed seat 11 spacing and fixing.
As shown in figure 11, the material of gearwheel 10 is carbon steel, and be processed into flat discoid, the through hole machining internal thread of the heart wherein, the worm structure 23 being D5 by internal thread and feed screw nut 7 diameter is connected, and is tightened to certain prestressing force.Gearwheel 10 retains the gap of 3 ~ 5mm between axis and bearing 9, not collide with bearing 9 when gearwheel 10 rotates.Ball screw pair causes the linear motion at ball screw 6 by the rotation of feed screw nut 7, drives nut 7 to rotate with the gearwheel 10 with large rotating inertia, makes the energy of vibration change into the rotation function of gearwheel 10.
During design, the radius of gearwheel 10 and thickness should design as requested, make the rotary inertia of gearwheel 10 reach usage requirement.In order to prevent flywheel from coming off when rotating speed is larger, locking mechanism can be designed on gearwheel 10.Small gear 14 is connected with gearwheel 10 by outer gearing, the axle 17 of small gear 14 is connected with axle fixed base 15, axle sleeve 16, lower end support 18 and generator 20 input shaft from top to bottom respectively, the upper end of axle fixed base 15 is connected with clevis mounting 2 by upper end support 13, the side of axle fixed base 15 is connected with generator pedestal 19 by bolt, and the shell of generator 20 is bolted on generator pedestal 19.The material of bearing fixed seat 11 is carbon steel, shape is that square steel plate contains small one and large one two circular concentric endoporus, large diameter of bore is identical with the external diameter of described bearing 9, large bore depth is identical with the thickness of bearing 9, little diameter of bore is less than large diameter of bore 4 ~ 10mm, the degree of depth of little endoporus is 4 ~ 5mm, thus described bearing 9 can be made to be located the inside being arranged on described bearing fixed seat 11.Great circle surrounding and square plate four angles offer respectively and is connected the bolt hole that described bearing fixed seat 11 and described bearing support cover plate 12 diameter are respectively D3 and D2.
The thickness of slab of bearing support cover plate 12 is 2 ~ 5mm, and shape is that square steel plate contains an endoporus.Square plate size is identical with bearing fixed seat 11, internal diameter 4 ~ 10mm less of the external diameter of bearing 9.Bearing support cover plate 12 and bearing fixed seat 11 are interconnected (as shown in Figure 2) by the hole bolt that diameter is D3, then to be fixed on intermediate mass block diameter by the bolt hole that diameter is D2 be on the mounting hole of D1.
Working principle:
As shown in Figure 1, when being transferred vibrations to upper strata supporting base 1 by vibration damping object, the relative displacement Dx produced between upper strata supporting base 1 and lower layer support seat 4, the rotation function that gearwheel 10 stores
relevant with angular velocity of rotation w with the rotary inertia J of gearwheel 10, be directly proportional to its rotary inertia, and to square being directly proportional of angular velocity of rotation.And the angular velocity of rotation of gearwheel 10
the relative velocity at rotary device 5 two ends is changed with the pitch p of ball screw 6 and energy
relevant.The relative velocity produced between upper strata supporting base 1 and lower layer support seat 4 is larger, and the angular velocity of rotation of gearwheel 10 is higher, then the rotation function of gearwheel 10 storage is more.By the rotary inertia of appropriate design gearwheel 10 and the pitch of ball screw 6, adjustable gearwheel 10 stores the ability of rotation function, when gearwheel 10 certain mass, should increase its rotary inertia as far as possible, to improve its energy storage capacity.For the gearwheel 10 of High Rotation Speed, due to the hundreds of times of the translational kinetic energy of generation when rotary motion kinetic energy is its vibration, thus utilize the gearwheel 10 of less quality, greatly absorb by the energy of vibration damping object vibration, thus the energy of vibration is delivered on generator by gearwheel 10 with engaging of small gear 14, reach the effect of the conversion of energy, storage and recycling.
More than describe the preferred embodiment of the present invention in detail; but the present invention is not limited to the detail in above-mentioned mode of execution, within the scope of technical conceive of the present invention; can carry out multiple equivalents to technological scheme of the present invention, these equivalents all belong to protection scope of the present invention.It should be noted that in addition, each the concrete technical characteristics described in above-mentioned embodiment, in reconcilable situation, can be combined by any suitable mode.In order to avoid unnecessary repetition, the present invention illustrates no longer separately to various possible compound mode.In addition, also can carry out combination in any between various different mode of execution of the present invention, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
