Adjustable device for balancing a fan

Abstract

An adjustable device for balancing a fan includes a hollow hub, which defines a receiving space and a plurality of fan blades extending outward from the hollow hub. Wherein, the receiving space includes an inner ring at the inner wall surface thereof and at least a balancing granular part is connected to the inner ring via a weak spot such that the weak spot is capable of being broken for separating the balancing granular part from the ring. Once the balancing granular part is removed to reduce weight at the position without the balancing granular part, the fan is able to run steadily instead of in a state of unbalancing.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention is related to an adjustable device for balancing a fan and particularly to a device, which is capable of regulating and keeping the fan running steadily. [0003] 2. Brief Description of the Related Art [0004] Generally, once any one of fans is running to drag air moving, it results in convention between the air and heat from a hot object is created to dissipate the heat effectively. It is known that the conventional fan provides a hub and a plurality of fan blades extending from the hub for performing task of dragging the air. However, in case of gravity of center of the fan deviating from the center thereof, vibration is created during the fan is running. [0005] The vibration fan makes the spindle thereof to become fatigue more easily and lead to shorten life span of the fan in addition to generating noise such that integral quality of a product associated with the fan and effect of heat dissip...

AI Technical Summary

Benefits of technology

[0007] In order to solve the preceding problem, an object of the present invention is to provide an adjustable device, which is capable of being simply made to correct unbalanced running of the fan, such that vibration resulted from the fan running unsteadily can be overcome substantially.

[0008] Accordingly, the adjustable device for balancing a fan according to the present invention includes a hollow hub, which defines a receiving space, and a plurality of fan blades extending outward from the hollow hub. Wherein, the receiving space includes an inner ring at the inner wall surface thereof and at least a balancing granular part is connected to the inner ring via a weak spot such that the weak spot is capable of being broken for separating the balancing granular part from the ring. Once the balancing granular part is removed to reduce weight at the position without the balancing granular part, the fan is able to run steadily instead of in a state of unbalancing.

Problems solved by technology

However, in case of gravity of center of the fan deviating from the center thereof, vibration is created during the fan is running.

The vibration fan makes the spindle thereof to become fatigue more easily and lead to shorten life span of the fan in addition to generating noise such that integral quality of a product associated with the fan and effect of heat dissipation is affected significantly.
