CYLINDRICAL WORM-GEAR Russian patent published in 2021 - IPC F16H1/16 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering. A cylindrical worm-gear contains a cylindrical worm and a worm-wheel made semi-circular and offset relative to the inter-axial transmission line in such a way that the extreme end sections of its crown are located on one side of the middle plane of the wheel, and having the largest wheel diameter from 1.8 to 2.0 of the inter-axial transmission distance. The worm-wheel is made with longitudinal and profile blockages of the side surfaces of the teeth in order to localize the contact spot, and the crown of the worm-wheel is made of heat-strengthened steel.

EFFECT: increases in the strength of the worm-gear.
