A general formula of assemblingrequirements for 2K-H planetary gear drivewith planetary gears equiangular or not is derived
the classical formula of assembling requirements of planetary gear drive is improvedand expanded
and the range of number ofteeth selected is extended. Moreover
the formulae for calculating the unbalance coefficientof radial force and dynamic disequilibrlumcentrifugal force caussed by this unequalsangle arrangement are presented.At last
to this kind of configuration
practical examples in the field of aviation andground .are enumarated.
