External gear slewing bearings are key components in lifting equipment, such as cranes, tower cranes, excavators, etc. The correct installation method can ensure the stability, reliability and life of the equipment. The following are the installation steps of the external gear slewing bearing: 1. Preparations Before installation, it is necessary to check the parts of the external gear slewing ring. Check whether the gears, racks, seals and lubricating oil are complete, and check whether they are in normal condition. It is also necessary to check whether the installation foundation of the equipment meets the requirements, such as flatness, strength, etc. 2. Install the support First of all, it is necessary to place the external gear slewing bearing on the installation position and lift it up with lifting equipment or other tools. Then, align the bottom of the support with the equipment's mounting base and secure with bolts. 3. Install the gear Before installing the gear, the rack and gear need to be cleaned and lubricated. Then, put the gear on the rack of the external gear slewing ring and fix it with bolts. 4. Connect the hydraulic system Before connecting the hydraulic system, it is necessary to check whether the hydraulic pipelines and joints meet the requirements, and apply sealant. Then, connect the hydraulic pipeline to the external gear slewing ring and test it to ensure the normal operation of the hydraulic system.
