Since the original imported fag bearing vibration and noise analysis of the factors

As imported fag bearing noise is bearing directly or indirectly with the surrounding structure vibrations and issued. That is a lot of noise problem is the bearing vibration problem when the entire application process. Because in the number of rolling element bearing load in operation will have change, the direction of the load caused by migration, so the vibration is generated. And parts of waviness on bearing operational cooperation between ring and bearing seat, bearing ring is easy to cooperate with other components of the deformations can occur from time to time. In case of deformation, vibration will be output. In the process of operation, the damaged imported fag bearing components also can produce vibration frequency. To solve these problems need to be aware of is through the axial loading to reduce vibrations with the surrounding structure. It is loaded with rolling body so. The bearing and the shaft to solve the parts were machined to the required tolerances in the wave of imported fag bearing ring fit between the drive shaft. At the same time the correct configuration of using bearing and its application in can reduce application such as vibration, etc. When under radial load bearing, bearing the load and the load area, if the bearing has a certain radial clearance, the load of roller and inner raceway is not contact, but because of the action of centrifugal force may be in contact with the outer ring, therefore, under the low speed, when the centrifugal force is less than the rolling body weight, scrolling experience fall with inner raceway or bearing cage collision and to stimulate the natural vibration and noise, and has the following characteristics: a. Grease lubrication easy generation, oil lubrication is not easy to produce. When using inferior grease is easier to produce. b。 Often occur in winter. c。 For only when radial load and the radial clearance is bigger, also easy to produce. d。 Also can produce in a certain range and the different size of bearing its speed range is also different. e. Could be continuous sound may be interrupted. f。 The forced vibration often stimulate the outer ring of the second order and third order bending vibration mode, which produces the noise. By using the load method can effectively reduce the noise, reduce work fag import bearing radial clearance after installed, choose good lubricant can improve, some foreign enterprises to adopt light rolling body, such as ceramic roller or hollow roller and other technical measures to prevent the production of this kind of noise, the noise is very annoying, many people don't want to appear when using bearing such noise, but there's no way to solve, so let a person is very headache.
