FIELD: process engineering.
SUBSTANCE: tapered adapter features vertex angle exceeding 85 degrees, shell being confined by top and bottom flat circular flanges and provided with ribs of tee-bar cross-section. Said ribs are arranged both along cone generatrix and at an angle thereto to connect thrust points of top and bottom flanges. Circular rib is located perpendicular to adapter base plane while other ribs are located in planes perpendicular to adapter base. Metallic frame of high-strength aluminium alloy is secured by glue-mechanical joint to top flange. Metal embedded sleeves from high-strength aluminium alloy are glued into bottom flange holes. Said shell extends into top flange via vertical section to make the platform for assembly of suspended equipment elements on adapter inner side, at top flange. Vertical section is located at a distance from top flange inner edge. Vertical section plan view represents a circle wit local recesses formed by circle arcs.
EFFECT: decreased weight, higher stiffness.
