Installing the slewing bearing requires following certain steps and precautions. Here are some key steps and points:
1. Confirm preparations before installation: Before installing the slewing bearing, it is necessary to confirm whether the gear slewing drive and the motor are intact and undamaged. At the same time, check whether the dimensions of the various parts connecting the motor and the slewing bearing match. In addition, the positioning boss, motor and reducer input shaft connection parts need to be wiped clean, which can be wiped with gasoline or zinc-sodium water.
2. Adjust the system clamping ring: Rotate the screw on the dust hole on the outside of the slewing support flange, adjust the system clamping ring so that the dust hole can be aligned with the side hole, insert the inner hexagon and tighten it, and then remove the screw on the motor. Shaft key.
3. Connect the motor and the reducer: Connect the motor and the reducer naturally to ensure that the output shaft of the reducer and the input shaft of the motor are concentric, and the outer flanges of the two need to be parallel. This results in a longer service life, lower noise and ideal transmission efficiency. If the concentricity is inconsistent, it is easy to cause the motor shaft to break or the rotary drive to break and cause wear.
4. Installation bolts: During installation, do not use hammers to prevent excessive radial or axial force from damaging the bearings or gears. It is necessary to tighten the mounting bolts before tightening the force bolts. When tightening and installing the slewing bearing fastening bolts after applying oil, apply a little oil on the threads to ensure balanced friction resistance. Be careful not to use glue on the bolt locking parts.
5. Manual drive test: After the slewing bearing is successfully installed, you need to turn the drive by hand first to confirm that the drive is flexible and there is no jamming. Before starting the machine, the connecting screws need to be fixed. The no-load test run time should not be less than two hours. The equipment should be free of impact, smoothness, noise and oil leakage during operation. If any problems are found, they should be eliminated in time.
6. Regular maintenance: After starting to use, it is necessary to regularly check whether each fastener is loose to ensure that the equipment can operate normally. At the same time, the bearings should be lubricated and maintained regularly to extend the life of the bearings.
When installing the slewing bearing, care must also be taken to prevent dust, dirt or other impurities from entering the inside of the bearing to prevent reducing the performance of the bearing and causing early failure. Also avoid applying excessive axial loads, maintain appropriate temperature ranges, and follow safety procedures to prevent accidents.
