Changzhi slewing bearing... / ' (3,3,3) - The slewing bearing is a large bearing that can withstand comprehensive loads. It can withstand large axial and radial loads and overturning moments at the same time. Slewing support bearings generally have mounting holes, internal gears or external gears, lubricating oil holes and sealing devices, thus enabling the main engine to be compact in design, easy to guide and easy to maintain. Therefore, it has become a new type of mechanical component that has gradually emerged around the world in the past forty years. But how much do you know about slewing bearings? The following is an introduction to slewing bearings:
/ ' (3,3,3) - Slewing bearings are usually composed of worms, slewing bearings, shells, motors and other components . Since the core component adopts slewing bearing, it can bear axial force, radial force and overturning moment at the same time. There are many forms, but the structural composition is basically the same.
/ ' (3,3,3) -Slewing ring bearings include toothless, externally toothed and internally toothed four-point contact ball bearings, double row angular contact ball bearings, crossed cylindrical roller bearings, crossed There are four series of tapered roller bearings and three-row cylindrical roller composite bearings. Four-point contact ball bearings have high static load capacity, crossed cylindrical rollers have high dynamic load capacity, and cross-tapered roller bearings have pre-passed Yingneng enables the bearings to have greater support rigidity and rotation accuracy. The increase in load-bearing capacity of three-row cylindrical roller combined bearings leads to higher bearing heights. Various forces are borne by different raceways, so under the same force, the bearings The diameter can be greatly reduced, thus making the main engine more compact. It is a slewing bearing with high load-bearing capacity.
/ ' (3,3,3) - Slewing support bearings are widely used in large-scale rotation of lifting machinery, mining machinery, construction machinery, port machinery, ship machinery, and high-precision radar machinery and missile launchers. on the device. At the same time, we can also design, develop and produce various special structure slewing bearings according to the specific requirements of users.
