How to repair the worn slewing bearing
Any turntable bearing / slewing ring can not be worn out. Although wear can not be avoided, we can repair the wear very well. Here we talk about how to repair a worn turntable bearing.
Turntable bearings / slewing bearings in the repair process, and always at room temperature, no internal stress, no thermal deformation, cracks, annealing, softening phenomenon, without breaking, the potential impact. Combination of high strength, does not produce shedding phenomenon, no hard spots, high surface finish, adjustable hardness.
Slewing Ring gear broken tooth repair method is partial repair welding or repair, local repair welding method is: first the damaged parts of the residual crack matrix grinding wheel with a hand-held, with gasoline (oil) to clean; with a torch In this part of the preheating, when it reaches a certain temperature, with carbon steel electrode in the gear tooth damage to push the site of the tooth prototype, it is higher than the normal tooth surface 1-2mm; dispatch experienced mechanized fitter, Follow the tooth pattern test until the teeth meet the requirements.
When an entire tooth of the slewing ring gear is damaged, it can be cut along the root of the tooth and then the tooth root file is shaped. Then in the same kind of waste ring gear storage cut a tooth, processed into the shape corresponding to the base material, into the slot, with a toothed template stuck positioning. To ensure the consistency of pitch, and with double-wire clamp value-added after the teeth around with low-carbon steel welding. Finally, with a file and other tools to repair the weld seam, to ensure that the tooth meshing can be stabilized.
