INA CAM bearing adjustment method in use process produce noise

1, scars and restraint method of INA bearings rolling appearance if there is crack, indentation, or rust, like rivet rivet will attack the periodic vibration and noise, the cycle can be fixed but mostly, the corresponding relationship between rotating speed into the inevitable scars will continue in the channel, and scars on the ball, and the noise with the device and smooth and there is a premise of transformation. When this kind of noise restraint measures are: device can tap on a bearing, CAM bearings and shaft assembly and then a load bearing seat when avoid bearing oblique; Inventory to avoid INA bearing corrosion and transport to avoid impact vibration; Using high viscosity of smooth and fat. 2, dust ring rolling bearing with dust and other foreign body and its restraint, will attack the periodic vibration and so-called dust noise, the vibration and noise of intrusive, and with or without. Dust acoustic control measures are: to improve the way to clean the INA bearing, gear before the CAM bearings, shaft, hole and matching parts all stern qing shen clean; Clear smooth agent inside the foreign body; To improve the bearing seal; Avoid using data not pure or foreign bodies are embedded plastic stick to. 3, lubrication elements make up the noise and its countermeasures of lubricant aging scleroma, choose wrong, lack of lubricant or attack can cause INA bearing vibration and noise, and the noise is not necessarily the rules. About this situation, as long as chooses appropriate smooth agent, adjust its smooth dose, extends the using life of smooth agent and reasonable change cycle. When considering the high-speed bearing clearance not only should consider the above-mentioned factors, and to consider the influence of the axial thermal elongation of clearance, request CAM bearing under working state, namely in the working temperature is the best clearance, clearance is, and this, the outer ring groove ball center accurate registration form of the condition. Due to the high speed bearing makes every effort to reduce the relative sliding and internal friction, had better not use the inner and outer ring relative displacement method to adjust the ball along the axial clearance of INA bearings. Considering the amount of the interference with the bearing clearance, and be aware that materials at high temperature becomes soft and easy to deformation characteristics, and many times caused by the temperature change of normal temperature to high temperature must be the possibility of permanent deformation. High-speed bearing for CAM bearing in rotary system after dynamic balancing precision, shaft with a hole installation of INA bearings parts should have higher dimensional accuracy, form and position precision of the general requirements, especially the alignment of hole or shaft neck and shoulder verticality, and considering these problems, also must pay attention to the high speed and high temperature factors in the operation of the bearing. INA bearing system requires both high rigidity, asked for a light quality as much as possible, in order to overcome the contradiction, can take measures such as reducing the surface roughness and improve the surface strengthening the support stiffness, in order to improve the use of hollow shaft to reduce the system quality, etc.
