Deformation-preventing supporting device of slewing bearing

TLDR: In this paper, a deformation-preventing supporting device for a thin-wall bearing is presented. But the deformation is not considered. But it is assumed that the bearing can be installed and used.

Abstract: Provided is a deformation-preventing supporting device of a slewing bearing, wherein a great deformation circumstance of a thin-wall slewing bearing is avoided in lifting, transporting and storing process, and installation and use of the slewing bearing can be guaranteed. The deformation-preventing supporting device includes a top cover, a chassis, connecting blocks, extending arms, female thread blocks, locking nuts, bolts and jack catches; the circular top cover and the chassis are concentrically and parallelly arranged; at least three connecting blocks are uniformly distributed between the top cover and the chassis and radially disposed; the extending arms are disposed on outer ends of the connecting blocks; the female thread blocks are disposed on the outer ends of the extending arms; the locking nuts are disposed on outer sides of the female thread blocks; the bolts are disposed in the locking nuts; the jack catches are disposed on the outer ends of the bolts; and rubber layers are disposed on surfaces of the jack catches. The deformation-preventing supporting device has simple structure, convenience in operation and high stability; and a force applied to supporting of a thin-wall bearing is moderate and uniform so as to guarantee installation and use of the slewing bearing.
