The vibration of the damage caused by high temperature bearing four aspects

The vibration of the damage caused by high temperature bearing four aspects in the high temperature bearing vibration production in general, high temperature rolling bearing itself does not produce noise. The so-called 'high temperature bearing noise', is actually the high temperature of bearing vibration, directly or indirectly, on the surrounding structure to produce acoustic effects. This is why many timeshare vibration problem can be considered to be noise problem, involving the application of the high temperature bearing. Incentive due to variation in the number of rolling batch production load when a load in a high temperature bearing radial load, the load of rolling element bearing capacity quantity in the process of operation will be a little change, this provoked the important research direction of load deviation. Thus can generate vibration is not to in order to prevent, but can through analysis of axial preload to ease, loading in all rolling body ( Discomfort and used in cylindrical roller bearing high temperature) 。 Part of the damage to the equipment or the wrong operation, small local temperature bearing raceway and rolling element may be damaged. In operation, high temperatures across the damaged bearing a scroll to produce specific oscillation frequency. NSK temperature frequency analysis can identify the damage of bearing parts. This principle has been in the state monitoring device was used to detect temperature bearing damage. In order to calculate the frequency of the high temperature bearing, see the application 'high temperature bearing frequency'. The precision of the related components in high temperature bearing ring and high temperature bearing or the shaft system under the condition of the close cooperation between, high temperature bearing ring with the adjacent two parts match the shape and deformation. If we present different deformation, could advance in the running to produce a vibration. Pollutants if running in the environmental pollution, impurities may enter high temperature bearing, rolling and rolling body. The vibration level depends on the number of contaminants in the crush, size, and composition. Although there is no typical frequency patterns, but could hear the noise of interference.
