Timken thrust needle roller bearing damage reason and maintenance skills

In front of the thrust needle roller bearing complete destruction, it provides found enough time use, do not ignore the existence of this kind of friction, it will make cycling landing speed, let the long interval of brawn take greater speed slower. If about the appearance of rough subtle level, if the oil film have appropriate thickness, smooth the surface stress generated by the probability is quite low, which is why the right to choose the appropriate oil to stop the cause of the smooth, but, if beyond the oil film pressure load of pu value ( The fatigue load limit, such as high speed, high pressure shock) Tired will come sooner or later, the data. In order to let the timken bearing axis of clamping, avoiding the phenomenon of bushing friction ( This phenomenon can produce high temperature on the high speed rotating machinery are filled, the formation of smooth dry up oil and cause heat to jammed, form the outage) So bearing thunk within and outside the bowl ( Industry is also called the bearing box) Using a 'interference' phenomenon, plain that the shaft is greater than the dang, or bowl larger than the load content, this kind of interference is a big demand of talent strength load, this load demand for palin to stop hitting tremendous strength, which makes palin in the process of tapping damage, so the big timken bearing usually adopt heating on the industrial, hydraulic jacking method. ( 1) As deputy information on metallurgical alloy difficulty levels. ( 2) Data and affinity to smooth agent. ( 3) As a deputy data in the condition of no smooth friction factor. ( 4) The microstructure of materials. ( 5) Thermal conductivity of materials. ( 6) Data can appearance size and characteristics of the oxide film. With oil pump will come into your timken bearing high pressure oil through the nozzle, into the thrust needle roller bearing in the bearing at the other end into the oil in the tank. In bearing high speed rotates, and insist on roller frame is around with fairly high rotate speed makes air flow, using ordinary smooth method can smooth the oil to the thrust needle roller bearing, then required by high radiation will be smooth oil spray to double row deep groove ball bearing, the position of the nozzle should be placed between inner ring and adhere to the center.
