無球軸承旋轉(zhuǎn)。近年來，研制成功了世界上首臺永磁軸承離心泵。本發(fā)明挑戰(zhàn)了傳統(tǒng)的機械轉(zhuǎn)動的概念，即“沒有軸，沒有軸，沒有泰州NSK軸承”。

Ball-less bearings rotate. In recent years, the first permanent magnet bearing centrifugal pump in the world has been developed successfully. The invention challenges the traditional concept of mechanical rotation, that is, "no shaft, no shaft, no Taizhou NSK bearing".

新型永磁軸承離心泵僅具有轉(zhuǎn)子、無旋轉(zhuǎn)軸和有形軸承，實現(xiàn)了永磁力作用下無形軸承的功能。研究人員說，永磁體力來自兩個磁體之間的力。軸承內(nèi)圈固定在葉輪上，外環(huán)固定在定子上。

The new type of centrifugal pump with permanent magnet bearings only has rotors, no rotating shaft and tangible bearings, and achieves the function of invisible bearings under permanent magnet force. Researchers say the permanent magnet force comes from the force between two magnets. The inner ring of the bearing is fixed on the impeller and the outer ring is fixed on the stator.

永磁泰州NSK軸承離心泵廣泛應用于工業(yè)、農(nóng)業(yè)、醫(yī)藥等行業(yè)。葉輪的形狀像飛碟，在永磁力的作用下處于自**度全懸浮狀態(tài)。電機軸拉緊一個盤以吸引固定在泵體葉輪上的另一個盤旋轉(zhuǎn)。葉輪的旋轉(zhuǎn)驅(qū)動葉輪中的液體旋轉(zhuǎn)以產(chǎn)生離心力。當流體到達葉輪周邊時，流速較高，當流體流出離心泵時，流速降低。流體的部分動能轉(zhuǎn)換成壓力能，從而完成輸送液體的過程。

The permanent magnet Taizhou NSK bearing centrifugal pump is widely used in industry, agriculture, medicine and other industries. The impeller is shaped like a flying saucer and is in full suspension state with self** degree under the action of permanent magnetic force. The motor shaft tightens one disk to attract another disk fixed on the impeller of the pump body to rotate. The rotation of the impeller drives the liquid in the impeller to rotate to produce centrifugal force. When the fluid reaches the impeller's periphery, the flow velocity is higher, and when the fluid flows out of the centrifugal pump, the flow velocity decreases. The partial kinetic energy of the fluid is converted into pressure energy, thus completing the process of conveying the liquid.

永磁軸承離心泵具有三個優(yōu)點：

Permanent magnet bearing centrifugal pump has three advantages:

首先，轉(zhuǎn)子與泵體之間沒有*機械接觸和摩擦噪聲，這使得離心泵體積更小，能*量效率更高，應用更廣泛。實驗表明，永磁泰州NSK軸承離心泵無需旋轉(zhuǎn)軸和機械軸承即可輸送液體。

Firstly, there is no mechanical contact and friction noise between the rotor and the pump body, which makes the centrifugal pump smaller, more efficient and more widely used. Experiments show that the permanent magnet Taizhou NSK bearing centrifugal pump can transport liquid without rotating shaft and mechanical bearing.

其次，永磁軸承離心泵可以無機械磨損、無潤滑、無密封、無維護地無限期運行。

Secondly, permanent magnet bearing centrifugal pump can operate indefinitely without mechanical wear, lubrication, sealing and maintenance.

第三，永磁軸承的應用表明，傳統(tǒng)軸承不是不可缺少的。科學家們說，永磁軸承離心泵的葉輪只有當永磁力和流體力的所有組合力平衡時才能穩(wěn)定地懸浮和旋轉(zhuǎn)。

Thirdly, the application of permanent magnet bearings shows that traditional bearings are not indispensable. Scientists say that the impeller of a permanent magnet bearing centrifugal pump can be levitated and rotated stably only when all combined forces of permanent magnet force and fluid force are balanced.

第四，當粗磨外滾道時，留給精磨的泰州NSK軸承磨削量應該適當。粗磨滾道的橢圓度、圓度、滾道位置、滾道擺動和溝槽精度應保證滿足工藝要求，這是不容忽視的。如果粗磨滾道的精度較差，為了使精磨滾道的精度滿足工藝要求，需要人工提高粗磨保持率。

Fourthly, when rough grinding the outer raceway, the grinding quantity of Taizhou NSK bearing left for fine grinding should be appropriate. The ellipticity, roundness, raceway position, raceway swing and groove accuracy of rough grinding raceway should be guaranteed to meet the technological requirements, which can not be ignored. If the accuracy of rough grinding raceway is poor, in order to make the precision of fine grinding raceway meet the technological requirements, it is necessary to improve the roughing retention rate manually.

第五，隨著加工余量的增加，精*密磨削的進給量和切削量將增加。從長遠來看，這會影響機床的精度，導致精*密磨削精度的下降。實驗表明，當深溝球軸承的橢圓度、邊緣圓度、滾道位置、滾道側(cè)擺和泰州NSK軸承滾道槽精度滿足技術要求時，滾道精磨的粗磨余量應為0.1個百分點左右。-0.15mm。此外，當外滾道粗糙時，不允許燃燒。

Fifth, with the increase of machining allowance, the feed and cutting amount of precision grinding will increase. In the long run, this will affect the accuracy of machine tools, resulting in a decline in precision grinding accuracy. Experiments show that when the ellipticity, edge roundness, raceway position, raceway sideswing and raceway groove accuracy of Taizhou NSK bearing meet the technical requirements, the roughing allowance of raceway finishing grinding should be about 0.1 percentage points. -0.15mm. In addition, when the outer raceway is rough, combustion is not allowed.
