FIELD: mining industry.
SUBSTANCE: invention relates to chain wheel for underground mining, particularly, to chain scraper conveyor with chain drive. Proposed chain wheel with first rim consisting of first tooth elements uniformly spaced over perimeter of chain wheel body and at least one second rim axially displaced relative to first rim and consisting of other tooth elements uniformly distributed over perimeter. Sides of tooth elements pointed to each other are provided with cavities which serve as contact surfaces of lying links of chain. Contact surfaces in cavities of each tooth element consist of wear lining made of wear-resistant material.
EFFECT: increased service life of chain wheels.
