The turntable bearings are widely used in large-scale slewing devices such as hoisting machinery, mining machinery, construction machinery, port machinery, marine machinery and equipment, as well as high-precision radar machinery and missile launchers. At the same time, it can also design, develop and produce various special structure turntable bearing bearings according to the specific requirements of users.
How to check the turntable bearing?
How to properly use the tooth surface of lubricating turntable bearing?
What should I pay attention to before installing turntable bearing?
1. Before each crane works or at least once a week, visually check the bolts on the turntable bearing;
2. After the turntable bearing works for 100 working hours for the first time, check whether the bolts are loose, and check again at the 300th working hour; after that, check every 500 working hours; the inspection interval should be shortened under severe working conditions. If the bolts are found to be loose during the inspection, please stop the construction operation, and immediately contact the local after-sales service department, and the factory or professional technicians will check and decide whether to disassemble and inspect immediately;
3. The turntable bearing should be filled with lithium-based grease before installation;
4. When replacing the bolts, wipe the bolts clean, apply thread tightening glue, and then tighten them;
Use the crane in accordance with the requirements of the operation manual and the lifting performance table, or check the fastening bolts regularly as required, so as to avoid the risk of fatigue failure of the bolts.
The turntable bearing ring gear has been coated with anti-rust oil before leaving the factory. The validity period of this anti-rust is generally 3 to 6 months. After the validity period is exceeded, the anti-rust oil should be coated in time. In addition, in use, the turntable bearing is prevented from being exposed to direct sunlight. It is forbidden to rinse the turntable bearing directly with water to prevent water from entering the raceway and prevent hard foreign objects from approaching or entering the tooth meshing area.
Before the turntable bearing is installed, the installation surface of the main engine 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 ferrule of the turntable bearing has a quenched soft belt area, which is marked with "S" on the end face of the ferrule. When installing, the position of the soft belt should be placed in the non-load area or the non-regular load area (the plug hole is always located in the soft belt. place).
With the increase in market demand, the types of turntable bearings are also expanding. To meet these growing demands, LYXQL Slewing Bearing Co., Ltd. founded has various turntable bearings and they are all more effective, reliable, and consistent.
LYXQL Slewing Bearing Co., Ltd. founded in 2003, is the leader manufacturer of large size slewing bearings in China. As one of the national key high-tech enterprises, LYXQL became the GEM listing company successfully on July 13, 2020 (stock code 300850).
