Drawings
Fig. 1 is a schematic view of the structure of the present invention;
in the figure, 1, a foundation, 2, a fan base, 3, a fan shell, 4, an installation groove, 5, a damping air bag, 6, a damping spring, 7, a spring abdicating groove, 8, a hose, 9, a channel, 10, an inflation tube, 11, a pressure gauge and 12, a valve are arranged.
Detailed Description
The utility model provides a damping fan, its includes fan housing 3, fan base 2 and multiunit damping device, fan base passes through bolt fixed mounting on basis 1, has seted up mounting groove 4 on four angles of fan base respectively, and is equipped with passageway 9 intercommunication, every group between the adjacent mounting groove damping device includes damping airbag 5 and damping spring 6, damping airbag fixed mounting is in fan base's mounting groove, and damping spring fixed mounting is in damping airbag top, wear to be equipped with the hose 8 with damping airbag intercommunication in the passageway, fan housing bottom is equipped with spring groove 7 of stepping down with the corresponding position of damping spring, and the spring inslot of stepping down is located at damping spring's top.
Further, be equipped with the gas tube hole of stepping down (not shown) with the passageway intercommunication on the fan base, gas tube 10 is installed to the gas tube hole of stepping down department, gas tube one end and hose intercommunication, the other end stretch out the gas tube hole of stepping down to install valve 12 and manometer 11 on the gas tube, when the manometer shows that pressure ratio is lower, can open the valve, aerify through air pump or other air supplies, in order to guarantee damping device reliable operation.
When the fan runs, because ground or other equipment produce vibrations, shock attenuation gasbag and damping spring can receive the vibrations ripples, prevent that it from spreading to fan axle and motor's transmission shaft department, make fan axle and motor's transmission shaft axle center misalignment, lead to rotor and shell or fan axle and shell collision or wearing and tearing each other, and influence the result of use of fan, or reduce the life of fan. And to the vibrations that fan self operation produced, because damping device includes shock attenuation gasbag and damping spring, shock attenuation gasbag fixed mounting is in the mounting groove of fan base, damping spring fixed mounting is in shock attenuation gasbag top, wear to be equipped with the hose with shock attenuation gasbag intercommunication in the passageway, through the hose intercommunication between four gasbags, can make the atmospheric pressure of four gasbags keep unanimous, thereby change the vibrations that produce because self motion, make the fan remain balanced state all the time, thereby guarantee that the fan axle aligns with the transmission shaft axle center of motor all the time, guarantee the motion reliable operation of fan.
Meanwhile, the fan base is fixedly installed on the basis through the bolts, the spring yielding grooves are formed in the positions, corresponding to the damping springs, of the bottom of the fan shell, the spring yielding grooves are formed in the tops of the damping springs, the structure is simple, the fan base is very convenient and fast to install, the fan base is installed on the basis through the bolts, and the spring yielding grooves in the fan shell are aligned with the corresponding springs and then are put down.
To sum up, the utility model provides a pair of shock attenuation fan, simple structure, simple to operate uses reliably, can extension equipment life.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
