ROTARY INTERNAL ENGAGING PLANETARY GEAR CONSTRUCTION AND ANGULAR TRANSMISSION ERROR REDUCTION APPROACH

摘要

PROBLEM TO BE SOLVED: To reduce an angular transmission error while keeping difference in the number of teeth between an external tooth gear and an internal gear as unity in a rotary internal engaging planetary gear construction.;SOLUTION: In the rotary internal engaging planetary gear construction of X piece type comprising X pieces of the external tooth gear (X: an integer of 2 or more), preparing X pieces of the internal gear corresponding to X pieces of the external tooth gear respectively, setting the teeth number of X pieces of each external tooth gear at X*n (n: an integer), setting the teeth number of X pieces of each internal gear at (X*n)+1, arranging X pieces of the internal gear by shifting the phase by 1/X to each other, and then building X pieces of the external tooth gear which are fabricated by co-processing external teeth with X pieces of blank being put together into X pieces of the internal gear by moving in each eccentricity direction without rotating in relation to X pieces of the internal gear.;COPYRIGHT: (C)2002,JPO
