b) Setting Tooth Flank Play
Tooth backlash must be checked regularly and adjusted if required.
Ideally, the pinion is as close as possible to the main cogwheel without the teeth touching
If the cogwheels (pinion and main cogwheel) are too far apart, the teeth of both cogwheels will be dam-
aged.
If the pinion presses against the main cogwheel (gear runs without play), performance is decreased,
power cosumption is increased and the cogwheels will wear more quickly.
To set the tootk backlash, loosen the two fasten-
ing screws at the electro motor until you can push
the motor into the direction of the main cogwheel
with light pressure (only loosen screws slightly, do
not remove them!).
The motor pinion and the main pinion now en-
gage with one another backlash-free.
Put a thin paper strip (no more than 80g paper)
between the motor pinion and the main pinion.
Then manually turn the main pinion so that the
paper strip is pulled in between the two pinions.
The pressure of the paper pushes back the electric motor as far as necessary. Now fasten the fastening screws of the
motor in this position.
If you then turn back the main cogwheel so that the paper strip can be removed again, both cogwheels should have
the correct distance.
Never put any gear grease or oil onto the motor pinion and main cogqheel! Otherwise, dust, sand and dirt
deposits form on both cogwheels. This strongly increases wear or even causes the drive to lock!
