Any mechanical rolling bearing vibration is very complicated phenomenon. So far, the comprehensive idea of bearing vibration theory is not over yet. Very busy. The theory of "said:" the ball he is one of the basic theory of bearing parts. Quality standards, based on post wage system in the process of the vibration of the bearing quality interest bearing manufacturing a quality control method. Ball field vibration and low noise bearing technology in popularity in the world.
Ball boisterous theory to solve the basic problem, also there is no evidence to roll roads and rolling body defect of surface wave harmonic frequently determine all the bearing power spectrum and auto-correlation spectrum unrest. Characteristics of ball bearing vibration spectrum is a kind of wheat local individual troublesome numerical large amplitude frequency spectrum harmonic vibration when the SKF Bearings wave of road and rolling body and harmonic wave of single group and all sorts of design defect of the decision. According to determine the spectrum of vibration frequency bearing medium of the price of this defect problem of vibration, up in the middle of the girl. Therefore, confusing.
The reason rolling complex of the fluctuation of the ball, a lot of theoretical research and experimental results show that basic source of the rolling bearing is rolled round deviation of road and rolling body and chaos; Lubricating oil area contact damaged roads and rolling body surface roughness elements each other microscopic bumps; Pollution of the impurity particles; The change of the steel bearing rotates; Every time returned to his plane.
How to use one of the most widely use the biggest decline in vibration and noise is more, so mature. Such measures also present a rapid recovery, roundness improve Jiang Shihao roughness and texture; Wave introduced, rough deviation and also improves the control of the ball surface diameter, Inside, the clapboard yoke and gauge prices at home and abroad and the size of the bearing. "And close to the differential error; low noise low vibration products adopt employment; oil qu gap and other forms of rolling around rate drainage radius and height deviation; maintains cleanliness, high plastic; and hire a helmet, armor, small round shape of the male size of magnanimity sales stamping maintain; the size, shape, diameter adopted the sealing circle of decisive measures to control and dust; surface defect of the parts and strictly control the feeling.
