moreover, the additive dimension obtained by the application of formula (3) or (4) to the values of the rack tooth profile parameters obtained by the method of the basic parameters of rack tooth profile is lower than the original dimension of the rack tooth profile.
in the study of the addendum modification coefficient the author considers that the addendum modification coefficient method can be applied in the recreating of new external parallel-axis cylindrical involute gears according to iso standards by a generation cutting process. examples with the application of the addendum modification coefficient in the solution to practical problems in relation to the geometry and manufacture of gears shows the application of the addendum modification coefficient as an adjustment factor between iso and agma systems. moreover, the calculation utilized in the two practical cases and formulae relating to basic gear geometry given in table 3 can be taken as a base for solution in similar cases of geometrical conversion from the agma to the iso system.
m = bn normas agma para engranajes pdf 12 in the case of a helical gear the normal section of the gear teeth is defined by the helix angle, b; and for a spur gear b = 0, the normal section of the gear teeth is defined by the helix angle of the pinion and the pitch of the pinion (pp). in this case, the module of the helical gear is obtained by multiplying the helix angle by the module in the normal section mn of the gear teeth. therefore, the helix angle b = 10
