ORTHOGONAL DOUBLE-MODULE WORK GEARING Russian patent published in 2000 - IPC

FIELD: mechanical engineering, namely machine-tool manufacture. SUBSTANCE: orthogonal double-module worm gearing may be used instead of hypoid and spiroid gearings. Worm axis of given gearing is positioned in middle end plane of worm wheel. External diameter of worm wheel is equal to double value of interaxial distance. Worm turns in shifted end plane are made as double- and straight-sided rack, dividing straight line of which is parallel to worm axis, and it is positioned at definite space. Position of dividing straight line serves as starting point for reading of worm wheel radial shift. Worm turn is positioned along depth of worm wheel tooth. EFFECT: simplified construction. 1 tbl, 2 dwg
