IKO auto bearing assembly testing points for attention

Auto bearing on the environment for the first time inspection should be in the light environment, it is the best astigmatism, in order to better IKO bearings, was observed on the surface appearance and no crack and other anomalies. Such as cloud of mechanical wear and scratches, touch pressure in the process of bearing equipment can lead to shift, and result in poor equipment location, lead to IKO bearing the shape of the flat load and stress concentration, reduce precision and service life. When the detection of rivet head main observation is there a link between slanting, easing the welding position is not correct. The welding quality. Welding point is too small, do you have any welding or welding, solid ball card caused problems. IKO bearing test need to pay special attention to the process. There are also some problems needing attention. According to the journal equipped with auto bearing, namely first repair size after light grinding crankshaft according to regulations, choose to repair the size of the bearing assembly, the fitting clearance in conformity with the provisions. This way the quality is good, easy to operate, and can shorten the working hours, but when matching bearing should be paid attention to the following: matching new bearing, should check bearing hole of the roundness and taper error, and make it conform to the prescribed standards. Check, the bearing cover and torque tighten according to regulations, dosage of cylinder table or inside diameter micrometer, the roundness and taper error should not exceed 0. 02 mm, otherwise will disturb the normal fit clearance IKO bearings and shaft neck, accelerate bearing and shaft neck of wear and tear. New bearing put seat holes, each side was bearing shall be bearing surface above the 0. 03 - 0. 04mm。 Such after that car bearing pressure, bearing in the elastic deformation and to everyone here, not loose, and has the good performance of thermal conductivity. IKO bearing plate fixed teeth should be intact, or in the work can make the shift of the bearing, lubricating oil way blocked, the oil supply disruption, burn out parts. Bearing the reverse side should be smooth level off, are not allowed to use file processing, or padded pieces of paper, so as not to affect the cooling. But in the maintenance work, often will meet with some necessary conditions, such as bearings and shaft neck fit clearance is too large, or use the old bearing, allowing padded a layer of thin copper sheet on the back of the bearing, but it must be flat and spear out of the oil hole. In addition to pay special attention to the work environment or the pollutants in the water, which is most likely to lead to auto bearing rust, rust is lead to bad IKO bearing installation, early wear and tear, will lead to more serious waste is a direct relationship. Therefore, it is important to pay special attention to in water to moisten of course.
