Long-term Use Of Double Row Ball Slewing Bearing How To Do
Oct 10, 2017


In order to ensure Double Row Ball Slewing Bearing sufficient inventory, some manufacturers will buy Double Row Ball Slewing Bearings. Do not use for a long time, Double Row Ball Slewing Bearing stored in a place, lead to rust for a long time, resulting in Double Row Ball Slewing Bearings can not be used normally. Today Xiaobian is to introduce a long time double pole ball slewing bearing is not used, how to store. Hope that through the introduction, we all help.
Double Row Ball Slewing Bearing long-term storage conditions and matters:
1, the warehouse temperature: Double Row Ball Slewing Bearing in the factory are coated with anti-rust oil, the temperature is too low or too high will lead to rust-proof oil deterioration, room temperature should be controlled at 0-25 ℃.
2, the warehouse humidity: too high humidity will double the ball slewing ring corrosion, the relative humidity of the warehouse should be maintained at 45% -60%.
3, the warehouse environment: Double Row Ball Slewing Bearings are best stored separately, when must be stored with other items, with the other items must not be acid, alkali, salt and other chemicals. Placement should leave the ground, away from the heating pipe.
4, regular inspection: according to the provisions of the product rust, every 10-12 months to check once. If the oil seal is found to rust, should be re-oil seal packaging, to prevent other substances into the internal, resulting in double row ball slewing ring corrosion.
When the Double Row Ball Slewing Bearings do not have long, we must carefully maintenance, to prevent the Double Row Ball Slewing Bearing rust, corrosion and other problems, thus affecting the product is life and use.
When the Double Row Ball Slewing Bearing after installation, the operation of spiritual investigation, may be installed with the host surface mounting surface is not good, the installation of the axial clearance, can not make up for the deformation, support the negative gap, roll back in a negative gap state, rolling The body is difficult to run inside the raceway. Or the size of the gear meshing bad, or the size of the gear inside the card with foreign matter.
Remedy: re-processing the host installation plane, so that the installation plane to meet the requirements, re-adjust the size of the gear meshing backlash, in particular, pay attention to the maximum position of the gear beating, check to ensure that the size of the gear meshing position without foreign matter, swap a gap slightly larger.
Double Row Ball Slewing Bearing is a mechanical joint, is the core role. Double Row Ball Slewing Bearing flexible, strong, is widely used in a variety of machinery industry, was used in the port, light industry, machinery and other industries. Double Row Ball Slewing Bearings, especially in the crane has a very important role, will directly affect the performance of the crane. Today Xiaobian will introduce the Double Row Ball Slewing Bearing in the crane industry application advantages.
Double Row Ball Slewing Bearing in the crane application Double Row Ball Slewing Bearing in the crane application characteristics:
1, the car crane: the lifting part of the assembly in a general or special car chassis, according to the maximum weight, select the appropriate car chassis and the size of the Double Row Ball Slewing Bearings, the greater the chassis, mid-effect more stable, The bigger ones.
2, tire crane: tire crane with a flexible mobile, reliable lifting material form, off-road capability is very strong, in civilian, military are very wide.
3, the whole road cranes, suitable for poor conditions of local operations, such as road rugged mountain application of the crane effect is very good.
4, crawler cranes: crawler cranes, generally there is no slippery situation, generally suitable for muddy, smooth environment.
In the continuous progress of technological development, mechanical engineering presents a rapid development trend. The Double Row Ball Slewing Bearing is excellent performance of mechanical parts, its engineering machinery can withstand three kinds of force, so that the normal operation of machinery. On the current situation, many manufacturers in the Double Row Ball Slewing Bearing to obtain a certain benefit. However, in the Double Row Ball Slewing Bearing installation but also a full range of exploration. The following look at the next double pole ball slewing bearing installation technical specifications.
