Embodiment
Referring to figs. 1 through Fig. 4, the utility model Industrial fan embodiment is described further.
A kind of Industrial fan, comprise fixed central cylinder 1, several flabellums 2, described flabellum 2 is fixedly connected on fixed central cylinder 1 excircle side by screw, described each flabellum 2 is equipped with damping device, described damping device comprises the first shock structure 3, second shock structure 4, described first shock structure 3 one end is provided with the shock relieve vent 31 identical with the second shock structure 4 diameter, described second shock structure 4 is sealed and matched with shock relieve vent 31, described first shock structure 3 is hinged on fixed central cylinder 1 side near the other end of the second shock structure 4, described second shock structure 4 is hinged on the other end of flabellum 2 near fixed central cylinder 1 near first shock structure 3 the other end, vent 32 is provided with bottom described shock relieve vent 31, described vent 32 diameter is 0.1mm, when Industrial fan is when rotating, the potential energy that flabellum 2 produces near fixed central cylinder 1 the other end is maximum, and potential energy easily changes into the kinetic energy making flabellum 2 shake, and the shake produced, potential energy is delivered on the second shock structure 4, the second shock structure 4 is made to produce the potential energy of axial motion, because the second shock structure 4 is sealed and matched with shock relieve vent 31, when the second shock structure 4 needs to when sliding near fixed central cylinder 1 the other end, air pressure in shock relieve vent 31 reduces, shock relieve vent 31 is caused to need the second shock structure 4 just can be made to slide by vent 32 air-breathing, make there is certain pulling force to the second shock structure 4 in shock relieve vent 31, make the potential energy consumption of the second shock structure 4, effectively decrease the vibration amplitude of flabellum 2, when the second shock structure 4 needs to when sliding near fixed central cylinder 1 one end, air pressure in shock relieve vent 31 increases, shock relieve vent 31 is caused to need to be given vent to anger by vent 32 just to make the second shock structure 4 slide, make there is certain thrust to the second shock structure 4 in shock relieve vent 31, make the potential energy consumption of the second shock structure 4, effectively decrease the vibration amplitude of flabellum 2, because damping device creates comparatively stable damping function to flabellum 2, most potential energy is consumed by damping function, greatly reduce the vibration amplitude of flabellum 2, the repeatedly alternate load effect that flabellum 2 is subject to is in the limit of fatigue strength always, effectively prevent flabellum 2 permanent bending, greatly improve flabellum 2 working life, flabellum 2 can be conditioned oneself to long hours of work and high speed rotating.
Described first shock structure 3 is provided with the first fixed plate 5 near fixed central cylinder 1 one end, described first shock structure 3 is hinged on the first fixed plate 5, described first fixed plate 5 is threaded connection in fixed central cylinder 1 side, described second shock structure 4 is provided with the second fixed plate 6 near fixed central cylinder 1 the other end, described second shock structure 4 is hinged on the second fixed plate 6, described second fixed plate 6 is threaded connection on flabellum 2, described second fixed plate 6 is threaded in the central position of flabellum 2 near fixed central cylinder 1 the other end, damping device passes through the first fixed plate 5 and the second fixed plate 6 is hinged with fixed central cylinder 1 and flabellum 2 respectively, facilitate damping device and flabellum 2 is dismantled separately, facilitate the maintenance of Industrial fan, maintenance, and flabellum 2 is that flabellum 2 assembles the maximum position of potential energy near the central position of fixed central cylinder 1 the other end, potential energy can effectively be transferred on damping device by the second fixed plate 6, improve the stability of flabellum 2.
