The steel, which is determined by the design parameters of INA bearings structure, flexibility, quality, vibration damping vibration system composed of the operating conditions will produce and mechanical adaptation. Vibration caused by the deviation of manufacturing, the smaller the difference, the smaller the vibration. Steel ball surface roundness, roughness, surface roughness is the most influential factor on the vibration of bearing parts, the shape error and surface of the inner ring and outer ring raceway roughness, again is bearing cleanliness and lubricant quality etc.. Operation conditions such as installation conditions, speed, load direction axial bearing, value etc..
What are the physical quantity INA bearing vibration?
Physical quantity of bearing vibration vibration displacement, vibration velocity, vibration acceleration of three.
The vibration level and scope of application of the bearing?
Bearing vibration (acceleration) is divided into Z, Z1, Z2, Z3 four grades;
INA bearing vibration (velocity) is divided into V, V1, V2, V3 four grades.
Z, V level in bearing manufacturing plant on the standard deep groove ball bearing vibration within the scope of inspection;
Z1, V1 level in a bearing finished product inspection general requirements on bearing vibration;
Other motor bearing Z2, V2 level in Y series motor and the corresponding requirements;
Z3, V3 is suitable for vibration is strict. This level with the international advanced level.
