TLDR
In this paper, a dimension chain control and surface powder spraying technology of a slewing bearing is presented, which can realize very good corrosion, impact and wear resistance effects, and when a powder sprayed layer deforms, does not peel and does not lose the corrosion resistance, so the service life of the bearing is effectively prolonged.Abstract:
The invention discloses a dimension chain control and surface powder spraying technology of a slewing bearing. The dimension chain control of the slewing bearing comprises the steps of feeding, rough machining, fine machining, QPQ salt bath composite treatment and powder spraying to obtain a dimension chain; and the surface powder spraying of the slewing bearing comprises the steps of degreasing, cleaning, phosphatizing, cleaning, passivating, electrostatic spraying of powder, solidification and cooling. The technology using powder spraying realizes very good corrosion, impact and wear resistance effects, and when a powder sprayed layer is impacted, the powder sprayed layer deforms, does not peel and does not lose the corrosion resistance, so the service life of the slewing bearing is effectively prolonged; and dimension chain and cooperation requirements can be met through dimension chain control to realize a best assembling effect, so the reliability of the slewing bearing is improved, and the popularization use is easy.read more
