KOYO bearing used in the cause of the vibration testing analysis

The cause of the onset of bearing vibration has a lot of, mainly for the following stop check: 1, the number of load rolling body mass change and the excitation when a load to KOYO bearing radial load, the number of rolling element bearing load will be a slight change in the operation, that is: this provoked the load in the direction of migration. The resulting vibration is not to prevent, axial preload to ease, but after loading in each rolling element but not applicable to cylindrical roller bearing. 2, components of wave degree between the bearing ring and bearing or the shaft under the condition of the reamer, KOYO bearing ring with adjacent components are likely to match the shape and deformation. If appear deformation, can produce vibration in the operation. Therefore, the bearing and the shaft to stop the machined to the required tolerance is very important. Part 3, bearing damage due to error operation or unit, small local bearing raceway and rolling body may be damaged. In operation, rolled the damaged bearing parts will produce a particular vibration frequency. Bearing vibration frequency analysis are recognized the damaged parts. KOYO bearing is the key equipment of the ultrasonic cleaning machine system, as a result of the cleaning machine bearing task particularly bad working conditions, to accept the shock, vibration, overload continuously under the conditions of operation, and use life request more than 15 years, strong sex is particularly high request, therefore, the use of ultrasonic cleaning machine design and manufacture of bearing is put forward higher request. Bearing in the repair process, has been in normal temperature condition, do not produce internal stress, thermal deformation and crack, annealing, softening phenomenon, no broken, split the potential impact. Separation, high intensity, does not produce shattered phenomenon, no hard points, high brightness, hardness is adjustable. For low carbon steel and low carbon alloy steel, medium carbon steel and medium carbon alloy steel, high carbon steel and high carbon alloy steel, high strength alloy steel, stainless steel, cast steel, cast iron, copper and copper alloy, aluminium and aluminium alloy, zinc and zinc alloy nickel, chromium, nickel, chromium steel and unknown information cease to repair. Repair location accurate, sensitive, XiuFuLiang can control precision, also can not collapse the repair, after repair location can stop reply accurate size tooling grinding technology. Cleaning machine used in grinding cement, coal and other construction, chemical, ceramics and other industrial raw materials, has small volume, light weight, covers an area of less, low power consumption, saving energy to reach an agreement over 30%, long using life and so on a series of advantages. ( 1) Due to the maintenance staff in KOYO bearing assembly is not serious when a process, to force on bearings, causing stick to plastic deformation, contributed to the frame and ask the friction roller, roller clip to death, can not turn, bearing in motion by the strong impact the effect of cyclic loading, attack adhere to damage, ball pieces. ( 2) Due to the maintenance staff to bearing gland and 4631 l paper pad improper adjustment between the bearing outer ring, forming bearing axial momentum increases, in strong stick to frame under the action of impact load attack damage, ball pieces. ( 3) KOYO bearing itself generated when the grinding machining, heat treatment of the residual stress, thermal stress in the high load exercise is too big, fatigue strength decreases sharply, from stick to damage, ball pieces.
