Detailed description of the invention
See Fig. 1 ~ Fig. 2, a kind of frequency that the present invention relates to increases the vibrator that amplitude reduces automatically, and it comprises base 1, first bolt 2, covers the 3, second bolt 4, inner cap 5, plug 6, the 3rd bolt 7, end cap 8, flange shaft 9, bearing 10, spacer 11, sealing ring 12, inner ring 13, damping fluid 14, transparent cover 15, the 4th bolt 16, balancing weight 17, the 5th bolt 18, the 6th bolt 19, flat spring 20, the 7th bolt 21 greatly.
Wherein: large lid 3 is installed on base 1 by the first bolt 2, end cap 8 is arranged on the middle part right-hand member of large lid 3 by the 3rd bolt 7, transparent cover 15 is arranged on the middle part left end of large lid 3 by the 4th bolt 16, flange shaft 9 is laterally arranged on in the middle part of large lid 3 by bearing 10, the axle left end (power intake) of flange shaft 9 is positioned at the left of transparent cover 15, the axle left end (power intake) of flange shaft 9 is provided with transmission keyway, the axle right-hand member of flange shaft 9 is positioned at the left of end cap 8, the flange of flange shaft 9 is in the up-small and down-big eccentric setting in inside of large lid 3, inner ring 13 is connected with the flange outer rim of flange shaft 9 by the 5th bolt 18, inner cap 5 outer rim is connected with inner ring 13 by the first bolt 4, sealing ring 13 is provided with between the axle of inner cap 5 and flange shaft 9, spacer 11 is provided with between the right side of inner cap 5 and bearing 10, plug 6 is arranged on inner cap 5, inner ring 13, inner cap 5 and flange shaft 9 form a cavity, damping fluid 14 is filled in cavity, flat spring 20 and balancing weight 17 are also arranged in cavity, one end of flat spring 20 is connected with the axle of flange shaft 9 by the 6th bolt 19, the other end of flat spring 20 is connected with balancing weight 17 by the 7th bolt 21.Described inner ring 13 inwall is also provided with block 13.1, and the distance of inner ring 13 inner surface distance from top flange shaft 9 is not less than the size of balancing weight 17, and the oblique upper that block 13.1 is positioned at flange shaft 9 is arranged.Block 13.1 prevents flat spring 20 to be wound in flange shaft 9.
Operation principle: when additional transmission mechanism drives flange shaft 9 to rotate, the inner ring 13 linked together with flange shaft 9, inner cap 5, flat spring 20 and balancing weight 17 also will together with rotate, along with the increase of rotational frequency, increase along with angle of rotation acceleration also increases by the tangential acceleration of balancing weight 17, one end due to flat spring 20 is fixed in flange shaft 9, the other end of flat spring 20 is connected with balancing weight 17, the torque that such balancing weight 17 pairs of flat springs 20 produce also will increase, such flat spring 20 by bending moment and produce the elasticity of flexure distortion, torque is produced in plane own, the size of its deformation angle and the torque of applying are directly proportional, therefore, along with the increase of rotational frequency, balancing weight 17 is moved upward from the below Fig. 2, so just change the position of vibrator eccentricity, thus cause the reduction of amplitude.The damping fluid 14 arranged in the cavity that inner ring 13, inner cap 15 and flange shaft 9 form in addition can play the effect of steady amplitude.
