How to solve the noise dust bearing dust generated in the bearing is one of my company's main product, the company set research, development, manufacturing, technical services as one company to create value for customers as their business objectives. Below small to tell you about how to solve the noise dust generated in the bearing. Dust bearing the jarring sound and control jarring sound is harsh sound of metal friction cylindrical roller slewing ring that may occur on all occasions, mostly in larger models greased bearing in dust, in addition, more likely to occur in winter, when the dust of the bearing under pure radial load, and with different types of sizes, both prone to noise continuously occurring within a particular speed range and the radial clearance of the occasion prone It will be intermittent. Foreign raceway take special processing methods to prevent the emergence of sound jarring, if necessary, this dust can be used in bearings, slewing ring or appropriate to reduce the fine radial clearance, and improve the performance of grease and dust bearing to match the mechanical rigidity. When rolling the sound and control the impact of the larger models in the dust ball bearings or cylindrical roller slewing bearing low-speed operation under pure radial load, due to the centrifugal force of the rolling element is small, in the non-load zone of rolling element will the impact of cage or raceway and noisy. However, the higher the speed, the sound will disappear. The method of controlling the impact of sound rolling elements are: appropriate to reduce the radial clearance, the use of a reasonable structure of supple material bearing cage dust. Clean Environmental Protection Co., Ltd. Cangzhou unique dust bearing structure, economical and practical, simple and compact structure, installation easier, the wheel bearings for Φ vertical axis vertical axis 40, with the wear sleeve. Dust bearing is used to bearing axis, but this is only part of its role in supporting its essence is to be able to bear the radial load. Also it can be understood as it is used to a fixed axis. It is fixed shaft it can only achieve rotation, and control of its axial and radial. Motor without bearing the consequences is not work at all. Because the axis may be in any direction movement, the motor work requirements shaft can only be rotated.
