Characteristics and Application of Slewing Bearing
Slewing Bearing are precision grinding machines for precision machine tools and similar equipment. It plays a very important role in ensuring the accuracy and performance of the spindle and prolonging its service life. It is also called bearing oil.
Its main performance:
    1, the appropriate viscosity and good viscosity characteristics
In order to make the machine tool spindle temperature is not too high and make the machine thermal deformation, affecting the processing accuracy or poor bearing lubrication, should be based on spindle bearing structure, speed and bearing clearance, etc. Select the appropriate temperature of the lubricating oil and require a good viscosity characteristics , To prevent the spindle operating temperature and ambient temperature changes, the viscosity of the change is too large and affect its lubrication performance.
    2, good lubricity
    In order to maintain a uniform oil film between the spindle and the bearing contact surface, the oil film does not damage when the spindle starts or stops the movement to produce the impact load, and maintains good lubrication performance to reduce the friction and friction heat, Processing accuracy of the role, requires a good lubrication performance.
    3, good antioxidant
    Machine spindle in the use of circulating lubrication, the spindle bearing oil for long-term use without deterioration, so require a good antioxidant.
    4, good anti-rust
    As the oil in the spindle lubrication system during the work will inevitably be mixed into the air condensate water or machine coolant, so the oil has a good anti-rust.
Slewing Bearing can be used in different industries, but in all cases will lead to damage to the Slewing Bearing, and found in the Slewing Bearing damage, but do not know where the damage, only a comprehensive anatomy to find the damage point. The following Xiaobian will introduce the method of disassembly of Slewing Bearing.
In the disassembly of the slewing bearing, the outer ring of the slewing bearing is connected with the vehicle, the inner ring is connected with the vehicle, and the seal on the Slewing Bearing is clean and clean, and the equipment is separated by a crane, The screw on the bearing, the bolt is removed. In the steel ball and isolation sleeve all removed, the steel ball and isolation sleeve to check, if the isolation sleeve on the crack or damage to the timely replacement, and check the ball is clean the ball, and placed in the sun Watch, you can clearly see whether the ball on the pitting or pits.
For mechanical products, the slewing bearing is an indispensable part, but sometimes we will find it will be inflexible, if not flexible, then the use of the time there will be a lot of trouble, and there is no way very good To work, today Xuzhou Hailin Slewing Bearing Co., Ltd. for everyone to share the rotation bearing stuck or movement is not flexible reasons and solutions.
1, Slewing Bearing gear deformation or broken teeth caused by stuck or movement is not flexible. The corresponding solution: repair gear, re-welding gear.
2, Slewing Bearing sealing system there is a problem, this will cause the entry of debris, such as stones, sand, etc. caused by stuck or movement is not sensitive. The corresponding solution: all the debris clean up.
3, overload operation, resulting in Slewing Bearing movement is not flexible. The corresponding solution: the need to reduce the workload of the work.
4, Slewing Bearing position is not flat. The corresponding solution: the need to replace the platform position, work in a flat position.
5, Slewing Bearing appear lack of lubricating oil, grease caused by increased friction, resistance becomes larger, it will cause the movement is not sensitive. The corresponding solution: add the same specifications of the lubricating oil or all the replacement of lubricants.
Know the Slewing Bearing appears inflexible reasons and solutions, the future encounter this situation, we do not need to worry about. For the user in addition to the need to know this knowledge, but also need to understand the use of Slewing Bearing precautions and related maintenance methods.
