當淮安NSK軸承的半軸在感應器內加熱時，感應器產生的熱量除了加熱工件外，還可分為三種主要的散熱方式。

When the half axle of Huaian NSK bearing is heated in the inductor, the heat generated by the inductor can be divided into three main heat dissipation modes besides heating the workpiece.

1。向周圍輻射熱量。感應線圈配有磁鐵、絕緣漆和玻璃布。這種形式具有熱損失小、平均散熱量小、對電感燒損影響小的優點。

1. Radiate heat to the surroundings. The induction coil is equipped with magnets, insulating paint and glass cloth. This form has the advantages of small heat loss, small average heat dissipation and little influence on inductance burning.

2。冷凝水帶走熱量。這部分的輻射感應器使感應加熱工作an全。結果表明，冷凝水進口水溫在0～180度之間，說明冷凝水具有良好的傳熱性能，流量穩定，水溫上升幅度不大，超過180度。此后，由于長流道的存在，水溫大幅度上升，水溫上升，使傳熱變差。淮安NSK軸承很容易導致傳感器的后續部件（例如225）。溫度升高是感應線圈燒毀的主要原因。

2. Condensate takes away heat. This part of the radiation inductor makes induction heating work an all. The results show that the inlet water temperature of condensate is between 0 and 180 degrees, which indicates that the condensate has good heat transfer performance, stable flow rate and little increase in water temperature, which exceeds 180 degrees. Thereafter, due to the existence of long runners, the water temperature rises substantially and the water temperature rises, which makes the heat transfer worse. Huaian NSK bearings can easily lead to subsequent components of the sensor (e.g. 225). Increasing temperature is the main reason for the burnout of induction coil.

三。感應線圈的熱量傳遞到連接板上。連接板的電流密度小，水的橫截面積大，使該區域的水溫低，使感應線圈的熱量傳遞到連接板上。0-90度和270-360度感應線圈靠近連接板，導熱性好。但90-270度感應線圈遠離連接板，導熱性差，使該區域感應線圈溫度急劇上升，導致管道線圈燃燒。在這個地區。不同位置感應線圈熱流方向的比較。感應線圈在225度附近有大量的熱積累和bu良的傳導，因此感應線圈在該區域容易燒壞。

Three. The heat of the induction coil is transferred to the connecting plate. The current density of the connecting plate is small and the cross-section area of water is large, which makes the water temperature in this area low and makes the heat of the induction coil transfer to the connecting plate. The induction coils of 0-90 degree and 270-360 degree are close to the connecting plate and have good thermal conductivity. However, the 90-270 degree induction coil is far away from the connecting plate, and its thermal conductivity is poor, which makes the temperature of induction coil in this area rise sharply, leading to the combustion of pipeline coil. In this area. Comparison of heat flow direction of induction coils at different positions. The induction coil has a large amount of heat accumulation and buliang conduction near 225 degrees, so the induction coil is easy to burn out in this area.

滾道聲是進口淮安NSK軸承滾動體在滾道表面運行時產生的一種連續滑動聲。這是所有滾動軸承產生的獨特的基本聲音。一般來說，外球面軸承的聲音等于滾道的聲音加上其余聲音。軸承滾道聲音不規則。頻率超過1000Hz。主頻率不隨轉速變化，但總聲壓級隨轉速增大而增大。

Raceway sound is a kind of continuous sliding sound produced by the imported Huaian NSK bearing rolling element when it runs on the raceway surface. This is the unique basic sound produced by all rolling bearings. Generally speaking, the sound of the outer spherical bearing is equal to the sound of the raceway plus the rest of the sound. The sound of bearing raceway is irregular. Frequency exceeds 1000Hz. The main frequency does not change with the speed, but the total sound pressure level increases with the speed.

對于高滾道噪聲的淮安NSK軸承，滾道噪聲的聲壓級隨粘度的增大而減小，而對于低滾道噪聲的軸承，聲壓級隨粘度的增大而增大。當粘度增加到20 mm 2/s以上時，聲壓級降低，軸承座剛度增加，總聲壓級降低。電纜管道聲壓級。

For Huaian NSK bearings with high raceway noise, the sound pressure level of raceway noise decreases with the increase of viscosity, while for bearings with low raceway noise, the sound pressure level increases with the increase of viscosity. When the viscosity increases to more than 20 mm 2/s, the sound pressure level decreases, the stiffness of bearing seat increases, and the total sound pressure level decreases. Sound pressure level of cable pipeline.

大型軸承或外球面軸承在純徑向載荷下低速運轉時，由于滾動體的離心力較小，非載荷區的滾動體會沖擊保持架或滾道，產生噪聲。但是隨著速度的增加，聲音消失了。滾動體沖擊聲的控制方法包括適當減小徑向間隙、采用合理的軸承結構和美觀的材料保持架。

When large bearings or outer spherical bearings operate at low speed under pure radial load, because the centrifugal force of the rolling element is small, the rolling element in the non-load area will impact the cage or raceway and produce noise. But as the speed increases, the sound disappears. The control methods of rolling body impact sound include appropriately reducing radial clearance, adopting reasonable bearing structure and beautiful material cage.
