(1) The rolling sound of Huaian NSK bearing and its control method are continuous. When the imported Chevrolet bearing is running, the rolling element rolls on the rolling surface. Roll to make a basic sound. Generally speaking, the sound of the number roll is the sound of the roll, plus the rest of the sound. The rolling sound of ball bearing is irregular, and its main frequency does not change with the speed. However, the total sound pressure level increases with the increase of rotational speed. The higher the rolling sound is, the lower the sound pressure level of rolling sound is; the bearing with low rolling sound increases its sound pressure level to viscosity. When the bearing is 20 mm 2/d or larger, the imported bearing is reduced to a smaller size.
淮安NSK轴承座刚度越大,滚道总声压级越低。如果径向间隙过小,滚道的声级会降低。随着径向间隙的减小,声压级和主频将急剧增加。控制滚动噪声的方法是选择低噪声轴承,即小波变换。波纹轴承,并仔细选择工作条件。通过降低滚道的噪声,可以降低整机的噪声。
The greater the stiffness of Huaian NSK bearing seat, the lower the total sound pressure level of raceway. If the radial clearance is too small, the sound level of the raceway will decrease. With the decrease of radial clearance, the sound pressure level and main frequency will increase sharply. The method to control rolling noise is to select low noise bearing, i. e. wavelet transform. Corrugated bearings, and carefully select the working conditions. By reducing the noise of the raceway, the noise of the whole machine can be reduced.
(2)球面或圆柱滚子在和径向载荷作用下的低速冲击声及其控制方法。进口淮安NSK轴承空区的滚子离心力会冲击保持架或滚道,产生噪音。但是,随着速度的增加,声音会消失。滚动冲击声的控制方法是合适的。当径向间隙减小,采用合理结构时,采用柔性保持架轴承材料。
(2) Low-speed impact sound of spherical or cylindrical roller under radial and radial loads and its control method. The centrifugal force of the roller in the empty area of the imported Huaian NSK bearing will impact the cage or raceway and produce noise. However, as the speed increases, the sound will disappear. The control method of rolling impact sound is suitable. When the radial clearance decreases and the reasonable structure is adopted, the flexible cage bearing material is adopted.
(3)淮安NSK轴承滚动声及其控制方法为粗金属摩擦声。在大多数情况下,它可能出现在个圆柱滚子中,其中大多数是较大类型的润滑脂。与润滑循环相比,它具有较高的含油量和较低的基础油性能。此外,在冬季更常见。当径向载荷较大时,在一定的转速范围内,径向间隙较大,模型尺寸变化较大,容易发生,且会间歇性发生。舍弗勒采用特殊的外滚道加工方法,防止滚动噪声。如有必要,可使用这种轴承,或适当减小轴承的径向间隙,并可使用优zhi润滑脂。增加和的刚度。
(3) The rolling sound of Huaian NSK bearing and its control method are friction sound of rough metal. In most cases, it may appear in a cylindrical roller, most of which are larger types of grease. Compared with lubrication cycle, it has higher oil content and lower base oil performance. In addition, it is more common in winter. When the radial load is large, in a certain speed range, the radial clearance is large, the size of the model changes greatly, which is easy to occur, and will occur intermittently. Schaeffler adopts special processing method of outer raceway to prevent rolling noise. If necessary, this kind of bearing can be used, or the radial clearance of the bearing can be reduced appropriately, and the excellent Zhi grease can be used. Increase the stiffness of sum.
