Large slewing bearing is an important structural component in construction machinery, which is widely used in excavators, cranes, wind power equipment and other fields. Correct installation is critical to ensure the normal operation of the bearings and the stability of the equipment. This article will introduce the installation method of large -scale rotation branches in detail to ensure the reliable operation of the equipment.
The installation method of large -scale rotary support bearing
Before the installation of large -scale rotation support bearing, we must first prepare for. This includes cleaning the mixed objects on the installation base and the support base, checking the bearing and its components whether it is intact, as well as the tools and equipment you need to prepare.
2. Install the base:
Before starting the bearing installation, the base of the device must be installed correctly. The horizontal and peaceful integration of the base is essential for the normal operation of the bearings. The base is accurately adjusted through the horizontal meter and measurement tools to ensure the flat and horizontal level.
3. Install the Large slewing bearing:
Before installing bearings, the installation position of the bearing and base needs to be marked to ensure that the bearings can be accurately installed on the device. Then use the lifting equipment to slowly hang the bearings to the base, and ensure that the center of the bearing is consistent with the center of the base.

According to the actual situation of the device, connect the bearings and transmission devices. This may involve the correct installation of transmission elements such as gears and chains to ensure that the transmission system is coordinated with the bearing to achieve normal operation of the equipment.
5. Install a sealed device:
Large slewing bearing is usually equipped with a sealing device to prevent external debris from entering the bearing inside and protecting the bearing. After the bearing installation is completed, the sealing device is properly installed according to the design requirements to ensure that the sealing performance meets the requirements.
6. Adjust the bearing gap:
Large -scale rotary supporting bearing needs to be adjusted appropriately during the installation process to ensure that the internal gap of the bearings meet the design requirements. By rotating bearing and adjusting according to the actual situation, you usually need to carefully monitor the operation of the bearings.
7. Check the lubrication system:
Ensuring the normal operation of the lubrication system of the bearing is an important part of the bearing installation. Check the lubrication system, including oil pipes, oil pumps and other components, to ensure that lubricating oil can smoothly flow into the bearings and provide good lubrication.
8. Trial transportation:
After completing the above steps, testing is a step to ensure whether the bearing installation is successful. In the trial movement, carefully observe the operation of the bearings and check whether there are abnormal noise, vibration or temperature rise. Make sure that the equipment meets the design requirements in the trial operation.
Overall, the installation method of large -scale rotation support bearing requires experienced technical personnel to operate. In actual operation, according to the models and requirements of the specific equipment, combined with relevant drawings and technical specifications, the installation steps are carefully executed to ensure the safety, stable and reliable operation of the bearings, so as to provide a solid foundation for the normal work of engineering machinery.
