The oil formation of the INA bearing ring disposal method

Because of frequent use INA bearing, oil can reduce the use of the bearing life, how can we put an end to the oil on the bearing? Here to teach you a way to easily put an end to the oil on the bearing. Soft dry oil or rust cream hardening bearing, should dip in 100 ℃ ~ 200 ℃ hot oil, clamp bearing with forceps, brush with wool clean oil bearing. Soft dry oil or rust paste is heated to 100 ℃ ~ 200 ℃, condensation, it is easy to from a crack in the bearing of the scour in. Sometimes just put the bearing repeatedly swing in the oil. The oil into crevices from. In cleaning the centripetal spherical bearing, INA bearing should be the ball, pearl frame transverse transfer from the outer ring, internal ring into hot oil, again after a short cylindrical roller bearing when cleaning roller, beads, also should be the inner ring and outer ring off. ( 1) INA bearing raceway sound and its control method of raceway is when bearing is running, the roller rolling on the surface of the raceway and a line of continuous sound, is everything will be all attack in the rolling bearing characteristic of the sound at all. Ordinary bearing ring raceway is combined with other sounds. Ball bearing raceway is irregular, frequency above 1000 hz, its main frequency does not change with speed, but its total sound pressure level increases with speed to speed up. Raceway big INA bearings, the rolling sound of sound pressure level decrease with the increase of the viscosity; The raceway small bearings, the sound pressure level in the viscosity increases to about 20 was/s above, from decreased to increase somewhat. And the rigidity of the bearing, the greater the raceway of the lower the total sound pressure level. Such as radial clearance is too small, the total sound pressure level and race master frequency will increase sharply with the decrease of radial clearance. Control rolling way voice way: choose low noise bearing is bearing waviness is very small, that is, using carefully selected. Race often affect the mechanical noise, reduce the raceway can reduce the mechanical noise. ( 2) Rushing sound of the rolling element and its control measures larger models of ball bearings or cylindrical roller bearings under pure radial load speed, due to the centripetal force is small, roller in the impact load of rolling body will adhere to the frame or race and making noises. But along with the progress of the rotational speed, the noise will disappear. For impact noise control measures include: roller properly reduce the radial clearance, use with reasonable structure and data with kindliness insist on bearing frame. ( 3) INA bearing of rolling mill and its control way to roll is cylindrical roller bearing can attack the harsh metal in all places, most of the attacks in large type bearing grease is smooth, smooth and performance degradation in the base oil in fat are more likely to attack, can't attack when oil is smooth. In addition, more prone to make during the winter, when to accept pure radial load, easy to attack in radial clearance of places, and with different size, easy to attack in a certain speed range, both continuous and intermittent rendering. External ring raceway adopt special processing method to avoid roll ring, can choose this kind of bearing, if necessary or appropriate to reduce bearing radial clearance, using performance good fat and smooth progress and bearing rigidity of matching parts.
