KOYO needle bearing repair method using heat

Provide solutions for processing, but may be because of KOYO bearing heating for different reasons, so the solution is different also, so still have to treat, particular case is particular with the help of the technical staff to complete. If you look closely at orbit, will know that only bear radial load, bear the axial load of big, inherit the torque load, or extreme rigid in bearing box is not equal. Can check whether the needle roller bearing with unexpected load and installation error is too big, etc. , shall be investigated for KOYO bearings hold clues to the cause of damage and become. 1, KOYO bearings cleaning removing KOYO bearings under repair, first recorded bearing appearance, 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 bearing is not direct contact with dirt from the container. When cleaning, if to spin bearing with dirt, can damage the bearing rolling surface, should be pay attention to. In coarse clean oil, use a brush to remove grease, adhesive, after clean, roughly into fine cleaning). Fine cleaning, bearing side rotation in the cleaning of oil, while carefully cleaned. In addition, the clean oil is always kept clean. 2, KOYO bearing inspection and judgment to judge whether the bearing of the removed can be used again, check after clean needle roller bearing. Carefully check the raceway surface, rolling surface, 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. And then replace the bearing lubricant. 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 scroll and damage, especially the application of small bearing more need to pay attention to this problem. When using KOYO bearings, such as to protect the safety of use, so be sure to inspect the needle roller bearing, 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.
