Changes on Drive Pinion/Ring Gear
Since about January of 1984 manufacturing uses optionally drive pinions/ring gears, on
which a DM value (e.g. DM 75) is recorded instead of deviation "r" (N).
Since this DM value is equal to adjusting distance E (R, + r), the adjusting distance does not
have to be figured out for these drive pinions/ring gears.
-.
R, = Design distance 74.70 mm
E = Adjusting distance
r = Deviation
1 = Adjusting distance (R, + r)
2 = Pair number
3 = Backlash
