Description
本創作係有關於一種風扇監控裝置，尤指一種具有監控軸承狀況及預測軸承剩餘壽命的效果，進而更有效達到操作便利及節省成本之效果的風扇軸承壽命之監控裝置。
The present invention relates to a fan monitoring device, and more particularly to a monitoring device for the life of a fan bearing that has the effect of monitoring the condition of the bearing and predicting the remaining life of the bearing, thereby more effectively achieving the convenience of operation and cost saving.
按，散熱風扇為一種常見的散熱結構，其主要可提供電子元件、電機元件或有熱能產生之機械中，而可以啟動散熱風扇並抽取其中所產生的熱溫，協助揮散熱量進而達到散熱冷卻之目的，藉此，而能保護電子、電機或機械元件，使其得以延長壽命，以避免因高溫而受損及影響運作，因此，現今所常見的電腦主機、錄放影機或影印機中皆裝有散熱風扇。
而習知散熱風扇能夠維持運轉主要是透過其內的一軸承與散熱風扇的軸心相對運動，所以軸承是影響散熱風扇品質的重要關鍵之一，因此，軸承的使用壽命便顯得相當重要。
然，習知軸承於進行測試時，該軸承是裝設於一軸承測試機台上的軸筒座內，並一馬達上的軸心與軸承相樞設，然後將加速規或是與加速規同類型的感測器放置在軸承上(或是軸承附近)，且加速規與一數位信號處理器(digital signal processor，DSP)電性連接，所以當馬達驅動軸心運轉時，該軸承也會隨著該軸心相對運動，此時於該加速規會量測該軸承運轉的震動而產生一震動訊號，然後透過該數位信號處理器根據接收的震動訊號做分析運算處理，來得知軸承的狀況(如軸承是否有異常)。
雖習知於測量軸承時可得知軸承的狀況，但卻延伸出另一問題，就是因軸承測試機台上的空間有限，以導致加速規不易擺放，且加速規的成本也相當昂貴，進而因使用數位信號處理器的關係，使得於運算處理上也顯得複雜。
以上所述，習知具有下列之缺點：
1.加速規不易擺放，安裝受限；
2.成本增加。
是以，要如何解決上述習用之問題與缺失，即為本案之創作人與從事此行業之相關廠商所亟欲研究改善之方向所在者。
According to the heat-dissipating fan, the heat-dissipating fan is a common heat-dissipating structure, which can mainly provide electronic components, motor components or machines with thermal energy generation, and can start the heat-dissipating fan and extract the heat temperature generated therein to assist the heat dissipation and further achieve the heat-dissipating cooling. The purpose is to protect electronic, electrical or mechanical components to extend their life to avoid damage due to high temperatures and affect operation. Therefore, it is commonly used in computer mainframes, video recorders or photocopiers. There is a cooling fan.
However, the conventional cooling fan can maintain the operation mainly through the relative movement of a bearing and the axis of the cooling fan, so the bearing is one of the important keys affecting the quality of the cooling fan. Therefore, the service life of the bearing is very important.
However, when the conventional bearing is tested, the bearing is mounted in a shaft holder on a bearing test machine, and the shaft on the motor is pivoted with the bearing, and then the acceleration gauge or the acceleration gauge is used. The same type of sensor is placed on the bearing (or near the bearing), and the accelerometer is electrically connected to a digital signal processor (DSP), so when the motor drives the shaft to operate, the bearing will also As the axis moves relative to each other, the vibration of the bearing is measured at the acceleration gauge to generate a vibration signal, and then the digital signal processor performs analysis processing according to the received vibration signal to know the condition of the bearing. (If the bearing is abnormal).
Although it is known that the condition of the bearing can be known when measuring the bearing, another problem is extended because the space on the bearing test machine is limited, so that the acceleration gauge is not easy to place, and the cost of the acceleration gauge is also quite expensive. Furthermore, the use of the digital signal processor makes the arithmetic processing complicated.
As mentioned above, the conventional disadvantages have the following disadvantages:
1. Acceleration gauges are not easy to place and installation is limited;
2. The cost increases.
Therefore, how to solve the above problems and problems in the past, that is, the creators of the case and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.
爰此，為有效解決上述之問題，本創作之主要目的在提供一種具有達到監控軸承狀況及預測軸承剩餘壽命的風扇軸承壽命之監控裝置。
本創作之另一目的係在提供一種具有達到降低成本及操作便利的風扇軸承壽命之監控裝置。
