Slewing bearings are components used for supporting rotation in large machinery and are typically composed of inner and outer rings. If the teeth of a slewing bearing gear break, it may affect the efficiency and safety of the entire equipment.
Fatigue fracture due to prolonged operation
Long-term high-intensity operation may cause fatigue fracture in the teeth of the slewing bearing. The solution is to regularly maintain and inspect the equipment to ensure its normal operation, in order to avoid excessive wear and fracture.
Improper installation and use
Improper installation and use of the slewing bearing, such as overloading, overspeeding, and overloading, may also cause teeth breakage. The solution is to follow the instructions for the proper installation and use of the equipment, and avoid overloading, overspeeding, and overloading.
Quality issues with materials
Quality issues with the gears of the slewing bearing may also cause teeth breakage. The solution is to choose high-quality slewing bearing gears to ensure the normal operation of the equipment.
The teeth of the slewing bearing gear need to be regularly maintained. If maintenance is not carried out for a long time, it may cause teeth breakage. The solution is to regularly inspect and maintain the slewing bearing gear, and promptly identify and solve problems.
Complying with the instructions for the use of the equipment, regularly maintaining and inspecting the teeth of the slewing bearing, and choosing high-quality slewing bearing gears are effective methods for avoiding teeth breakage in slewing bearings.
In addition, if the gear of the slewing bearing has already experienced teeth breakage, repair measures need to be taken promptly to avoid affecting the normal use of the equipment.
(1) Shutdown inspection
The equipment needs to be shut down first, and a comprehensive inspection of the slewing bearing needs to be conducted to determine the specific location and cause of the teeth breakage problem.
(2) Gear replacement
If the gear is severely damaged, it needs to be replaced promptly to ensure the normal operation of the equipment.
(3) Gear repair
If the degree of fracture of the gear is not very severe, repair measures can be taken. Repair methods include welding, cold repair, and hot repair.
(4) Gear reinforcement
To avoid similar problems from recurring, reinforcement measures can be taken, such as installing support structures around the gear or increasing the thickness of the gear.
In summary, preventing teeth breakage in slewing bearings is crucial. Regularly maintaining and inspecting equipment, as well as using equipment correctly, are key to preventing problems. If a problem has already occurred, repair measures need to be taken promptly to ensure the normal operation of the equipment.
