Avoid the bearing system failure on five kinds of methods

High temperature bearing peeling channel by channel unilateral limit working position one main table limit position of spalling problem now channel and guard the borders with serious peeling band. Sources is China imported high temperature bearing system device management does not reach the designated position or suddenly appeared in the process of axial overload operation development. Take corresponding measures is to make sure whether through high temperature bearing device in place or will ease side clearance fit, the high temperature bearing outer ring in order to in order to make high temperature bearing high temperature bearing overload economic compensation is calculated. 2. High temperature bearing raceway position along the circumferential symmetric spalling table now stripping with stripping ring around the inner ring and outer surrounding detachment ( Namely, oval short axis direction) To the location of the symmetry, mainly due to the causes of elliptical hole is too big or hole half left shell type structure of particularly high temperature properties of the camshaft bearings on the motorcycle. When the pressure into the larger oval or half shell split fastening elliptical bearing outer ring of bearing seat hole temperature, on the gap in the direction of the short axis significantly reduced or even negative gap. Under the load of bearing temperature, inside is the circumferential rotation, outer ring tracking in the position of symmetry, only to remove traces of the short axis spalling. This is the early failure of bearing temperature, high temperature test instructions component after bearing the main reason for the failure, from the original process control of cylindrical bearing temperature becomes zero. 8μm27μm。 This value is much larger than radial clearance value. Temperature, therefore, can make sure that the bearing with serious deformation and negative clearance, the working surface structure easy to early rapid wear and spalling of abnormal operation. Countermeasures are shell hole machining precision or do not use the shell hole two and a half integral structure of the progress as soon as possible. High temperature influenced the bearing raceway tilt peeling a tilt of the endless belt work surface spalling inlet temperature of bearings, bearing temperature is shown in the tilted work condition, when slope Angle reach or exceed the critical state, the early and simple configuration unusually rapid wear and spalling. Main reason is due to poor device axis deflection, journal and shell holes and low precision, to take steps, to ensure the quality and the progress of high temperature equipment bearing shaft shoulder, shoulder hole axial runout precision. High temperature bearing ring ring fracture failure of common enterprise is relatively rare, is often a sudden overload. An important reason for relatively rich and complex, such as high temperature bearing the original data management defects ( Bubbles, shrinkage) , forging defects ( Burnt) , heat treatment of defects ( Overheating) , processing defects ( Some burns or micro cracks appearance) , host defects ( Poor device adverse, smooth, instantaneous overload) Etc. , once the overload or violent vibration impact load could make the ring fracture. Take corresponding countermeasures to prevent overload shock load, and the choice of an appropriate amount of interference, the progress space gear accuracy, improve the students use economic conditions and improves the high temperature bearing manufacturing quality cost control in the process of development. 5. High temperature bearing stickers frame abnormal rupture stent fracture belongs to contingency failure forms, reasons are as follows: a. Attached to the frame of abnormal load.
