Slewing bearing is a kind of large bearing with special structure that can bear large axial load, radial load and overturning moment and other comprehensive loads at the same time. Therefore, when installing the slewing bearing, we must do the relevant inspection work, or the matters needing attention during installation. For this kind of large bearing, we must do a good job in maintenance and storage, so as to avoid the following damage to the slewing bearing, cause it to not work properly.
Before the slewing bearing is installed, the installation surface of the host should be checked first. It is required that the support should have sufficient strength, the connecting surface should be machined, and the surface should be smooth and free of debris and burrs. For those that cannot be machined to achieve the required flatness, special plastics with high injection strength can be used as fillers to ensure the accuracy of the installation plane and to reduce vibration. The ring of the slewing bearing has a quenched soft belt area, which is marked with "S" on the end face of the ring. When installing, the position of the soft belt should be placed in the non-load area or infrequent load area (the plug hole is always located in the soft area). belt).
When installing the slewing bearing, radial positioning should be performed, the mounting bolts should be tightened crosswise, and the rotation of the bearing should be checked. There should be sufficient pre-tightening force when tightening the bolt, and the pre-tightening force should be 70% of the yield limit of the bolt material. Mounting bolts should be equipped with quenched and tempered flat washers and spring washers are strictly prohibited.
After the slewing bearing installed and put into operation, after 100 hours of continuous operation, it should be fully checked whether the pre-tightening torque of the mounting bolts meets the requirements, and the above inspection should be repeated every 500 hours of continuous operation. After the slewing bearing is installed, an appropriate amount of grease should be filled, and the bearing should be rotated while filling to make the grease evenly distributed. After working for a period of time, the slewing bearing will inevitably lose a part of the grease, so the slewing bearing in normal operation should be replenished with grease every 50 to 100 hours.
During transportation, the bearing should be placed horizontally on the vehicle, and there should be measures to prevent sliding and vibration, and auxiliary support should be added if necessary. Only a slight tilt is allowed, and large bumps or vibrations should be avoided. After unpacking, screw the lifting bolt into the lifting hole of the inner ring or outer ring to transport the bearing to the installation position.
The above is the explanation of the key points of the installation and maintenance of the slewing bearing. The inner and outer surfaces of the slewing bearing are evenly coated with anti-rust lubrication oil on both sides of the bearing, and the packaging is wrapped with plastic film kraft paper and linen strips. The outer surface of the large-size slewing bearing should also be wrapped with plastic cloth. For small size slewing bearings, use wooden boxes.
