About the vibration of the bearing

What are the main factors affecting bearing vibration? Determined by bearing structure design parameters of stiffness, flexibility, quality, such as damping of vibration system under the condition of operation will produce that can meet the needs of its mechanical vibration. Manufacturing process of the deviation caused by vibration, the smaller the deviation, the less vibration. Roundness, waviness and surface roughness on the surface of the steel ball is the most profound effect on the vibration in the bearing parts, followed by the shape of the inner ring and outer ring channel error and surface roughness, again is bearing cleanliness and lubricant quality, etc. Operation conditions such as the installation conditions, speed, direction of axial load, quantity, etc. Of the bearing vibration in the physical quantities have? A vibration displacement of physical measurement of characterization of bearing vibration, vibration velocity and vibration acceleration of three. Bearing vibration level and scope of application? Bearing vibration ( Acceleration) Divided into Z, Z1, Z2, Z3 four grades; Bearing vibration ( Speed) : V, V1, V2, V3 four grades. Z, V grade is suitable for the bearing manufacturer of standard regulation range of deep groove ball bearing vibration test; Z1, V1 grade suitable for general requirement of the bearing vibration bearing inspection; Z2, V2 grade is suitable for the Y series motor and the corresponding requirements of other motor bearing; Z3, V3 level suitable for vibration have strict requirements. This level has the international advanced level.
