FIELD: manufacturing technology.SUBSTANCE: cowl for high-speed cabin of elevator comprises rectangular top cover (1), with four edges of which there are front cover (2), rear cover, left cover (4) and right cover. Top edges of rear cover, left cover (4) and right of cover are connected to upper cover (1) through arc-shaped transition section (6) respectively, while lower edges are turned outwards. Inner side surfaces are rigidly connected with arc-shaped transition sections (6) and upper cover (1) by means of ribs. Said fairing is fixed on upper part of elevator cabin. Section (6) can perform air circulation and reduced resistance to air flow and protection of cabin during high-speed movement of lift.EFFECT: fairing provides prevention of lateral and vibration during high-speed movement of elevator cabin and considerably reduces noise.9 cl, 3 dwg |
