当淮安NSK轴承的半轴在感应器内加热时,感应器产生的热量除了加热工件外,还可分为三种主要的散热方式.

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.向周围辐射热量.感应线圈配有磁铁、绝缘漆和玻璃布.这种形式具有热损失小、平均散热量小、对电感烧损影响小的优点.

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.冷凝水带走热量.这部分的辐射感应器使感应加热工作an全.结果表明,冷凝水进口水温在0～180度之间,说明冷凝水具有良好的传热性能,流量稳定,水温上升幅度不大,超过180度.此后,由于长流道的存在,水温大幅度上升,水温上升,使传热变差.淮安NSK轴承很容易导致传感器的后续部件(例如225).温度升高是感应线圈烧毁的主要原因.

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 (. 225). Increasing temperature is the main reason for the burnout of induction coil.

三.感应线圈的热量传递到连接板上.连接板的电流密度小,水的横截面积大,使该区域的水温低,使感应线圈的热量传递到连接板上.0-90度和270-360度感应线圈靠近连接板,导热性好.但90-270度感应线圈远离连接板,导热性差,使该区域感应线圈温度急剧上升,导致管道线圈燃烧.在这个地区.不同位置感应线圈热流方向的比较.感应线圈在225度附近有大量的热积累和bu良的传导,因此感应线圈在该区域容易烧坏.

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.

滚道声是进口淮安NSK轴承滚动体在滚道表面运行时产生的一种连续滑动声.这是所有滚动轴承产生的独特的基本声音.一般来说,外球面轴承的声音等于滚道的声音加上其余声音.轴承滚道声音不规则.频率超过1000Hz.主频率不随转速变化,但总声压级随转速增大而增大.

Raceway sound is a kind of continuous sliding sound produced by the imported Huaian NSK bearing rolling element when it runs on the raceway su-ce. 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.

对于高滚道噪声的淮安NSK轴承,滚道噪声的声压级随粘度的增大而减小,而对于低滚道噪声的轴承,声压级随粘度的增大而增大.当粘度增加到20 mm 2/s以上时,声压级降低,轴承座刚度增加,总声压级降低.电缆管道声压级.

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.

大型轴承或外球面轴承在纯径向载荷下低速运转时,由于滚动体的离心力较小,非载荷区的滚动体会冲击保持架或滚道,产生噪声.但是随着速度的增加,声音消失了.滚动体冲击声的控制方法包括适当减小径向间隙、采用合理的轴承结构和美观的材料保持架.

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.
