Adjustment method of SKF universal joint Bearing Damage
- 1. Listening: using hearing to identify irregular operation is a very common method. For example, using a screwdriver or electronic stethoscope to detect a simple abnormal noise is a method often used by experienced operators and maintenance personnel.
- The damage degree of SKF Bearing in use can be determined by listening, touching and observing.
- If the universal joint bearing is in good operation, it will make a low whine sound. If the bearing makes sharp hiss, squeak and other irregular sounds, it may indicate that the bearing is in poor operation.Adjustment method of SKF universal joint Bearing Damage
- 2. Touch: high temperature often indicates that SKF Bearing has been in abnormal condition, and high temperature is also harmful to the lubricant in the bearing. However, the high temperature of the bearing is caused by the lubricant in the bearing at some times. If the universal joint bearing operates for a long time at a temperature exceeding 120 ℃, the service life of the bearing will be reduced.
- The causes of bearing high temperature include insufficient or excessive lubrication of lubricant, impurities in lubricant, excessive load, bearing damage, insufficient clearance and friction caused by oil seal.
- Under normal circumstances, the bearing will have a natural temperature rise just after lubrication or after lubrication, and it will last for one to two days.Adjustment method of SKF universal joint Bearing Damage
- 3. Observation: if the SKF Bearing is well lubricated and there are no sundries and moisture, it indicates that the oil seal of SKF Bearing is not worn. If the original bearing box is opened, visually check the universal joint bearing and regularly check the oil seal.
- Check the condition of the oil seal near the bearing to ensure that they are sufficient to prevent hot liquid, corrosive liquid and gas from penetrating into the bearing along the axis.
- If the oil seal is damaged, replace it as soon as possible. Check the automatic lubrication system to ensure that the oil or grease enters the bearing and the correct amount is added.
- At the same time, check whether the lubricant is discolored or blackened. If so, it usually indicates that the lubricant contains impurities, which is also harmful to the use of the bearing.Adjustment method of SKF universal joint Bearing Damage
