Bearing: electric rear wheel bearing rust

Marks the emergence of the marks can be divided into two cases: engine produced by the vibration at work, or on the surface of the outer ring raceway of local area, appear some closely arranged along the rolling direction parallel to the axial stripes, according to the marks. LB— — Light metal solid cage, inner ring guidance, under the action of electromagnetic vibration force of the generator, lead to a significant bearing axial resonant frequency doubling. The north cold area, the surface of the axle box heat faster, if you have any individual with car axle box above the top temperature is higher than the temperature of baidu, is not normal phenomenon, should find out the reason. Note: heating heating does not exceed degrees Celsius, motor at run time because of the fan will produce negative pressure, so as to increase the oil inside and outside differential pressure, lead to the oil. In fact, the carbon content of martensite in the micro zone is uneven, near around carbide carbon concentration is higher than from carbide parts original ferrite, so they began to occur martensitic transformation temperature is different, thus inhibiting the martensite grain grew up and display in the form of microscopic cryptocrystalline martensite. Bearing maintenance contact degree examination between bearing housing and bearing contact area is greater than %, the adjustment between gasket and block and gasket and the contact between tile uniform contact area is greater than %, the tilting pad and the corresponding spindle and uniform contact area is greater than %. Things is not big, oil bath lubrication the lubrication method is immersed part of the bearing lubricating oil, used in the thrust bearing of vertical shaft, and should not be used for horizontal spindle radial bearing. Without oil bearing is a kind of both metal bearing characteristics and bearing characteristics of novel lubrication bearing lubrication system, by load matrix, and the special formula of solid lubricating materials lubrication. a) With shaft with retaining ring embedded in the shaft inside the groove, it is mainly used for axial force is not big and the speed is not high; b) With screw shaft end ring fastening, can be used under the high speed under large axial force, should be screw locking measures; c) With a round nut and lock washer with fastening, mainly used in high speed, large axial force; d) With conical sleeve, lock washer with and round nut fastening, used in optical axis, the inner ring for the taper hole of the bearing. If the bearing inner ring configuration in the big end in not heating position, you have to keep frame damage, remove the roller, the inner ring ontology exposed, directly to the coil in the roll channel to heat. C is called the normal load, P> for C diagram of lathe spindle bearings after tolerance and fitting, therefore, the mixture ratio of the shell bearings on the shaft hole with the matter. Transmission bearing role will auto transmission is directly related to its function, auto transmission must meet the requirements of all kinds, including shift smoothly and high output power, compact structure, light weight, rate and low noise, etc. , and the demand is higher and higher.
