Slewing ring （2500LB S235JR Nipolet Flange）is also called "slewing ring" because its shape is similar to a plate. Its diameter is usually 0.2 ~ 10m. It is a large bearing that can bear axial and radial load and overturning moment. The slewing bearing is composed of mounting hole, inner gear ring or outer gear ring, isolation block, cage, lubricating oil hole and sealing device. Therefore, it can make the design structure of the host compact, easy to guide and easy to maintain.
This time introduces the principle and application method of Slewing ring （2500LB S235JR Nipolet Flange）that was not introduced last time
Ⅳ、 A basic working mode of slewing ring（2500LB S235JR Nipolet Flange）
1. Point contact rolling working mode of slewing ring （2500LB S235JR Nipolet Flange）
The roller contact mode is mainly used for the four contact points of rotary bearing and rotary ball. This working principle requires high quality of steel ball and uniform angle of track for combined bearing of radial and axial force of point contact.
2. Surface contact rolling combined working mode of slewing bearing,slewing ring（2500LB S235JR Nipolet Flange）
The surface contact rolling combined working mode is mainly used for three rows of roller slewing bearings. Its advantage is large contact surface, uniform bearing force and flexible rolling.
3. Surface contact rolling sliding combined working mode of slewing bearing
The surface contact rolling sliding combined working mode is mainly used for the turntable bearing. Now the new turntable bearing has compact structure and high precision. Therefore, the surface contact rolling sliding combined working mode is suitable.
4. Rolling sliding combined rolling working mode of slewing ring（2500LB S235JR Nipolet Flange）
The main rolling sliding combined rolling working mode is mainly used for ball column combined slewing bearing. This principle has the advantages of small eccentricity, long service life and dual structure of roller and ball.
Ⅵ、 Daily maintenance of slewing ring（2500LB S235JR Nipolet Flange）
1. The slewing ring （2500LB S235JR Nipolet Flange）shall be maintained for 100 working hours, and the bolt pre tightening torque shall be checked.
2. If more than 10% of the bolts are loose, check again within 200 working hours.
3. Check every 500 working hours in the future; The inspection interval shall be shortened under severe working conditions.
4. If a bolt is found to be loose below 80% of the specified torque after the equipment has worked for 2000 hours, the bolt and two adjacent bolts shall be replaced.
5. If 20% of the bolts are found to be loose below 80% of the specified torque, the bolts shall be replaced with new ones.
6. After the equipment has worked for 14000 hours in total, all bolts shall be replaced.
7. For equipment with high slewing speed or continuous slewing or frequent operation, add oil every 100 working hours.
8. In case of bad working conditions, it is necessary to improve and shorten the time interval of lubricating grease filling.
Each component has its basic structure construction and related construction principles, especially for the slewing ring, a new mechanical component. At the same time, it has been applied in more fields.
