If the inner ring of the bearing produces fretting wear, both the inner ring and the journal of the rolling bearing can be repaired on site with metal brush plating technology. Technical requirements for bearing bush scraping According to the requirements in ‘JB/T5000. The raceway makes the bearing fully and evenly lubricated, and the bearing is well lubricated under heavy load and high temperature, which prolongs the service life of the bearing.
After idling for a period of time, check whether the working current and voltage are normal and whether the crusher has abnormal noise before transporting the stone for crushing work. Check carefully whether the spindle is smooth, whether there are defects such as rust, bruises, etc. To avoid the ‘stuffy car’ phenomenon caused by broken jaw bearings, we should pay attention to: To 1.10-1998 Heavy Machinery General Technical Conditions Assembly’, the tile back must be scraped and ground to make it meet the specified technical requirements.
The elastic deformation of rolling bearings is very small, and it is not necessary to consider in most machines, but in some machines, such as machine tool spindles, bearing rigidity is an important factor. In addition, various types of bearings can also be pre-tightened to achieve the purpose of increasing the supporting rigidity. Because these two types of bearings bear the load, their rolling elements and raceways are in point contact with poor rigidity.
When it is too large, the friction of the bearing will increase, the temperature rise will increase, and the service life of the bearing will be affected.; The rigidity of the bearing refers to the force required to produce unit deformation of the bearing.
Such as angular contact ball bearings and tapered roller bearings, in order to prevent the vibration of the shaft and increase Mechanical ball bearing Factory the supporting rigidity, a certain axial force is often applied in advance during installation to make them press against each other. The amount of preload cannot be too large. Generally, cylindrical and tapered roller bearings should be used
