The raceway of the non-standard deep groove ball bearing and the method of controlling the raceway sound The raceway sound is caused by the sound of the rotating body of the non-standard bearing rotating on the non-standard bearing when the non-standard bearing is in operation. , The characteristic is that it is slippery and continuous. This kind of sound is the basic sound that all rotating non-standard bearings will cause. Some of the most extensive non-standard bearing noises are the noise of raceway non-standard bearings combined with other sounds. The sound of the raceway will also be different. For example, the sound of the non-standard bearing of the ball non-standard bearing is the sound of the non-standard bearing of the non-standard raceway of the ball bearing. Its frequency must be above 1000Hz, and then its main frequency and other The different area of ​​non-standard bearing is that it does not change with the transmission ratio, but its total noise coefficient does increase with the acceleration of the transmission ratio.

Some drum sounds, especially in large non-standard bearings, the inverse proportion of the noise coefficient of the drum non-standard bearing sound and the degree of viscosity is that the higher the viscosity, the smaller the drum sound. The noise figure is proportional to the viscosity, that is, the higher the viscosity, the higher the noise figure.

The changing trend of the flip sound is related to the bending stiffness of the non-standard bearing seat. The bending stiffness of the non-standard bearing seat is inversely proportional to the noise coefficient of the flip sound, that is, the greater the bending stiffness of the non-standard bearing seat, the smaller the total noise coefficient of the flip sound. It is also related to the shaft diameter side clearance. The noise coefficient and main frequency of the shaft diameter side clearance and the raceway sound are inversely proportional. The smaller the shaft diameter side clearance, the greater the noise coefficient and the main frequency. After reading the above, the control method of the raceway sound is actually a bit of an eye. We can choose a non-standard bearing with a small wave shape, so that the noise will be effectively reduced, and we must be careful in the application specification. . The noise of the raceway is very harmful to the noise of the overall industrial equipment, and the reduction of the sound of the raceway can effectively reduce the noise of all industrial equipment.
