FIELD: mechanical engineering; conveyors. SUBSTANCE: proposed overhead belt conveyor includes support frame with closed guides secured on frame at both sides of conveyor and passed over drive and end drums, and endless conveyor belt with roller hangers uniformly spaced and second on conveyor belt for movement along guides. Each guide is made in form of single pipe. Hangers resting on guides are connected to belt by means of crossmembers. Rollers enclosing guide from top and bottom are made in form of truncated cones, optimum angle of roller opening being α = 2Karctg(P/H) where α is roller opening angle, rad; P is radial load on roller, N; H is axial load on roller, N; K is manufacture error coefficient chosen in interval from 0.8 to 1.2. EFFECT: improved reliability of conveyor in operation. 2 dwg
