Gear Terminology Question
Gear Terminology Question
(OP)
I deal with European OEMs quite often and was wondering if anyone knows the difference between these three terms related to gearing specs:
Profile Shift
Profile Offset
Correction Factor
In the US we use "Profile Shift" to indicate how much the gear is to but cut under or over pitch diameter.

addendum vs 1.00 times the module
addendum. So if for example they
show 1.25x, subtract 1.00 and it shows
the .25 x the module is the profile
shift.
RE: Gear Terminology Question
they generally refer to
it as x.m where x is ratio
which you multiply times the
module and it give you the
profile shift in millimeters.

addendum is shortened by k times the module,
Example x.m = 1.25m k.m = .10m, then the addendum is 1.25m minus .10m equals 1.15m addendum.
