Tips on Quality Inspection of Bearing

If the bearing is installed improperly, it will cause the bearing temperature to rise rapidly and damage, and even the bearing stuck to death and other major accidents. The bearing should be installed in place, and the rotation is flexible.
First, the rotation of the bearing with a stethoscope and other tests, a strong metal noise, abnormal sound, irregular sound, such as abnormal. The reasons for poor lubrication, shaft or bearing poor accuracy, bearing damage, foreign body invasion and so on.
Second, the bearing temperature, generally based on the bearing seat of the external temperature speculation. But the use of oil holes directly measured the temperature of the bearing outer ring is more accurate. Bearing temperature, starting from the operation began to rise, usually 1 to 2 hours after the temperature stability. If the bearing is installed poorly, the temperature will rise sharply, abnormal temperature. The reasons such as too much lubricant, bearing clearance is too small, poor installation, sealing device friction is too large and so on. High-speed rotation of the occasion, bearing structure, lubrication mode selection error is also the reason.
Third, small machinery can be rotated by hand to confirm whether the rotation is smooth. Check the project because of foreign objects, scars, indentation caused by poor operation, due to poor installation, poor processing of the mounting seat torque instability, due to clearance is too small, the installation error, sealing friction caused by excessive torque Wait. If no abnormalities can start power operation.
Fourth, large-scale machinery can not be manually rotated, so no-load start immediately cut off the power, mechanical idling, check for vibration, noise, rotating parts have contact, etc., confirmed no abnormalities, into the power operation.
