Reductions of meshing and bearing clearances are requisite in design and production of small backlash planetary gears. In this case, however, there is a risk of losing proper load distribution to each planet gears, which has risk of occurrence of non-working flank load. The state of non-working flank load increases unnecessarily working flank load and gives some undesirable influences on reliability of planetary gears. To solve this problem, this paper aims to analyze quantitatively about relations between the load distribution and position deviations of planet gears. These deviations are considered to be most influential to the problem in reality. About one type of the device with 4 planet gears, 20 kinds of combination pattern of the position deviations are selected out, and the influences of backlash, reduction ratio and gear module to the above relations are clarified. Consequently, allowable position deviations to avoid the state of non-working flank load are found out for various conditions and useful materials for design are obtained.
