Separated double-raceway slewing bearing

TLDR: In this article, a separated double-raceway slewing bearing is described, where a first connecting platform is arranged in the circumferential direction of the outer side wall of the inner rotating ring, and the section of the first connecting platforms is of a step-shaped structure; the second connecting platforms are superposed with each other and are fixed through bolts.

Abstract: The utility model relates to a separated double-raceway slewing bearing comprising an inner rotating ring, an upper raceway ring, an upper rolling ball layer, a lower raceway ring, a lower rolling ball layer and a gear ring, wherein a first connecting platform is arranged in the circumferential direction of the outer side wall of the inner rotating ring, and the section of the first connecting platform is of a step-shaped structure; a second connecting platform is arranged in the circumferential direction of the inner side wall of the gear ring; and the first connecting platform and the second connecting platform are superposed with each other and are fixed through bolts. The separated double-raceway slewing bearing is precise and stable in structure, reliable in working, convenient to mount, capable of greatly reducing the cost and lowering the machining difficulty and particularly suitable for application in wind power and construction machine industries.
