The use of the rolling bearings Koyo fever preventive maintenance countermeasures

Remove koyo bearing repair, the first recorded appearance of bearing, confirm the stock of lubricant residues, sampling inspection with lubricant, bearing. Common use gasoline, kerosene as a cleaning agent. Tear open come down to the bearing cleaning, coarse and fine fine cleaning cleaning, respectively in the container, first put on the metal mesh at the bottom of the rolling bearing is not direct contact with dirt from the container. When cleaning, if to spin bearing with dirt, can damage the bearing koyo, should be pay attention to. In coarse clean oil, use a brush to remove grease, adhesive, after clean, roughly into fine cleaning). Fine cleaning, rolling bearing in the cleaning of oil side spin, side carefully cleaned. In addition, the clean oil is always kept clean. In order to judge whether the bearing of the removed can be used again, check after clean needle roller bearing. Carefully check the raceway surface, koyo, cooperate with the state, the abrasion of cage, the increase of the bearing clearance, and presence of dimensional precision falling damage, abnormal. Non separation of small ball bearings, with one hand will support level, the inner ring spinning confirm whether smooth outer ring. Too much grease. Then replace the rolling bearing lubricants. Used engine oil lubrication needle bearing after xie used engine oil, if possible, should be impregnated with fresh oil and let the machine in low speed rotation for a few minutes. As far as possible make the oil collecting residual pollutants, and then purging in addition to the oil. And the use of grease lubrication koyo bearing in replacing grease, used by Joe in addition to the editor should avoid contact with cotton to any part of the spherical bearing. Because these residues fiber may wedged in between the koyo and damage, especially the application of small bearing more need to pay attention to this problem. 1, measure the size of the bearing form is various, had better use scale bearing in mechanism design. The nature, size, direction is changeable. Usually, the basic load rating on dimension table are displayed. Axial load and radial load, and so on, but also are important factors to select suitable for rolling bearing. When the size of the ball and needle bearing of proportion, usually have higher load capacity and rolling bearings under high vibration and shock loads. 2, on the bearing rotating speed, bearing is according to the type of bearing, size, precision, cage type, load, lubrication, and cooling way. 3, in some cases exerted pressure to koyo bearing in order to increase rigidity, this program is typically used for deep groove ball bearings, angular contact ball bearings and tapered roller bearing inner and outer circle of bias, shaft bending, shaft or the bearing box tolerance changes, matching error could lead to the eccentricity of the inner and outer ring. In order to prevent the eccentric Angle through the large, automatic self-aligning ball bearings, automatic self-aligning roller bearings, or self-aligning bearing seat is a better choice. Voice frequency and torque and rolling bearing according to produce high precision measure is made, so the voice and the torque is small. Deep groove ball bearings and cylindrical roller bearing used for in low voice, low torque has special requirements of the occasion. 4 tolerance, bearing, bearing of dimensional accuracy and rotation accuracy is according to ISO and JIS scale. For high-precision and high-speed machines, recommend the use of level 5 or above precision bearing, deep groove ball bearings, angular contact ball bearings and cylindrical roller bearings are used in high running accuracy mechanical. Rigid, when bearing to move body and contact pressure, will produce elastic deformation. Some mechanical need to minimize the elastic deformation. Roller bearing is smaller than ball bearings produced by elastic shape variables. When using koyo bearings, such as to ensure the safety of use of rolling bearing so be sure to check, check the size of its vibration and sound, temperature, the condition of the lubricant ( Whether the color and viscosity are changed, whether there is a foreign body) 。 Remember, the dosage of the lubricant, must be moderate, more waste, less is not a proper role, in use process, don't exceed the speed limit, because of excessive heat or burn and cause damage, if the working temperature of more than 100 degrees, so the oil 2 - should be replaced every year About three times.
