GEARING Russian patent published in 2004 - IPC

FIELD: mechanical engineering.

SUBSTANCE: tooth of driving wheel (1) of the gearing is made of a single-turn helicoid having the equilateral trapezium profile in the normal section of the turn. The tooth of the driving wheel engages tooth (4) of driven wheel (2) whose screw lead t is equal to the lead of the driven wheel (2) at diameter d passing through the mid-width of the gearing rim b and is determined from the relationship t= d/Z, where t is the lead in engaging, d is the diameter passing through the mid-width of the gearing rim of the driven wheel, and Z is the number of hollows in the driven wheel.

EFFECT: improved design.
