Abstract: Based
on the relation between tooth deformation and the transmission load of
spur gears, an equation is presented for the correlation between gear
static transmission error and the total amount of profile modification
of meshing teeth under a specific load. To determine the profile
modification parameters for gears with manufacturing errors, a principle
is put forward, that is, the maximum profile modification of meshing
teeth in designing gears should enable the elimination of the meshing
interference caused by manufacturing errors and the variation amount of
gear static transmission error should be kept within as a narrow range
as possible. Furthermore, formula is provided for determining the
profile modification parameters of meshing teeth for spur gears with
manufacturing error. Corresponding method for determining the parameters
is also proposed. Numerical simulation of system dynamic response
indicates that the approach has good effects on vibration reduction of
gear transmission.
Key words: Spur gears Static transmission error Tooth profile
