Gcr15 bearing steel: big truck clutch release bearing is broken

According to the nominal contact Angle is different, is divided into: radial bearing - contact - - - Nominal contact Angle for the centripetal bearing: the centripetal angular contact bearings - - - - Nominal contact Angle is greater than the centripetal bearing. Cling to some grease on the surface of the rotating element in shear under the action of tensile fiber mesh structure, make a small amount of precipitation of lubricating oil in the rotating element and seat on the surface of cambium lubricating film; The rest of the grease is still intact fiber mesh structure, cooling and sealing role. Heat curing, and improve the material performance and speed up the material curing time; , amount of added lubrication oil lubrication and interval, according to the table below, according to the amount of oil in the table, can achieve at least hours of supplementary lubrication. Spectrum is very single frequency doubling, only a lot of this kind of accident, also accumulated some practical skills, is this kind of bearing in the early part of the device after operation, monitoring the status of vibration, spectrum analysis was carried on. From the fault surface, belongs to the typical bearing outer ring problem, pieces of laser cladding, laser cladding which is also called laser cladding or laser deposition, is a new surface modification technology. Fan bearing chamber and wear of the main reasons: lack of lubrication bearing, due to the high working temperature, bearing damage and wear bearing chamber; Size tolerance, due to the gap between the bearing and the bearing chamber caused by relative motion and worn bearing axial channeling, bearing gland not pressure or bearing chamber size is too big to bearing, fan operation cause the axial channeling and wear and tear. Protector the main reason for the trip are: water pump motor overload; Water pump motor temperature rise too high; Water pump motor current is too large; The pump by matching supply voltage is too high. Check the fault can be controlled under the form, natural cooling after welding, through inspection welding layer does not crack, slag inclusion, porosity and less meat, can lower machining. Bearing WeChat: zhouchen - Methyl amino acetonitrile gren - Deep professional methyl amino acetonitrile. According to rolling bearing structure bearing types classified according to its can carry the load direction or nominal contact Angle different, divided into: the centripetal bearing - - - - Is mainly used to bear radial load of rolling bearings, the nominal contact Angle from to. （ E) Level - — Used in high speed, high rotating accuracy of rotation mechanism, such as precision machine tool spindle bearings, precision instruments and meters of the main bearing, etc. Equipment introduction this paper enterprise in normal production for # dryer drive side bearing wear problem caused downtime, the drying cylinder bearing a phi mm, bearing model for the way the bearing and shaft, uneven wear quantity for tight fit for mm. For high speed and high precision rotation mechanism, using level bearing a class, for example, high precision gear grinding machine, precision coordinate of spindle bearing bed, aviation, high-speed photography main bearing, etc.
