Embodiment Construction

[0015] Such as figure 1 , figure 2 , image 3 , Figure 4 with Figure 5 As shown, a magnetic suspension shock-absorbing fan includes a shock-absorbing frame and a fan 5. The shock-absorbing frame is composed of a shock-absorbing upper cover 1, a shock-absorbing base 2, and a number of limiters 3. The bottom of the shock-absorbing upper cover 1 and the shock-absorbing A number of magnets 4 are symmetrically arranged on the top of the base 2. The magnets of the shock-absorbing upper cover 1 and the magnets of the shock-absorbing base 2 have the same magnetic poles. The stopper 3 is fixed on the shock-absorbing base 2 to limit and prevent the shock-absorbing upper cover 1. When the fan is removed, the bottom of the fan 5 is fixed to the bottom frame 6 on the top of the shock-absorbing upper cover by bolts 7.

[0016] When the present invention is working, the magnets of the shock-absorbing upper cover and the magnets of the shock-absorbing base have the same magnetic poles, so the...

Abstract

The invention discloses a magnetic levitation damping fan. The magnetic levitation damping fan comprises a damping frame and a fan body, the damping frame is composed of a damping upper cover, a damping base and a plurality of limiting devices, a plurality of magnets are symmetrically arranged at the bottom of the damping upper cover and the top of the damping base, and the opposite faces of the magnets of the damping upper cover and the damping base are same magnetic poles; and the limiting devices are fixed to the damping base and can limit the damping upper cover to prevent the damping upper cover from falling off, and the bottom of the fan body is fixed to a bottom frame of the top of the damping upper cover through bolts. According to the magnetic levitation damping fan, the fan bodyis mounted on the magnetic levitation damping frame, the repulsion force of the same poles of the magnets are utilized to offset the vibration force of the fan, operation stability of the fan is effectively guaranteed, and the advantages of ingenious design, durability and the good damping effect are achieved.

Description

Technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a magnetic suspension damping fan. Background technique [0002] The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. The fan converts the rotating mechanical energy into gas pressure energy and kinetic energy and transports the gas. Existing fans will vibrate during operation. Fan vibration is a common phenomenon in operation. As long as it is within the vibration control range, it will not cause much impact. However, if the vibration of the fan exceeds the standard, it will cause damage to the bearing seat or motor bearing, loosening of the motor anchor bolts, damage to the fan casing, blades and air ducts, and motor burning and heating. This will reduce the performance of the fan and even cause it to fail at all. . In severe cases, vibration may cause accidents and endanger human health and working enviro...
